Description of the DELTA System

ADA's DELTA System is a multi-room/multi-source system that utilizes ADA's

exclusive ADA Bus™ Bi-Directional serial data network. The Delta-88 acts as both a source

selector, preamplifier, and amplifier. Apart from being the ultimate in multi-room technology,

the Delta System will operate perfectly as an audio-video selector when one zone (two, or up

to 256 zones) is set up as a home theater using ADA's SSD-66 Dolby ProLogic® Surround

Sound Decoder or SSD-66THX Home THX® Controller. The user is able to select audio sources

(and video sources when using the VSM-8 Video Switching Module) with the MC-3000 Music

Control, MC-3011 Decora® Style Keypad (Single Gang), MC-3800 Music Control with Nu-

meric Direct Access (triple gang), MC-3000 OD All Weather Outdoor Keypad, or MC-0038

Hand-Held IR Remote for that zone, while other zones can select their own source (from their

own keypads or IR remotes). All of the information that appears on the L.E.D. display of the

Delta-88 (and MT-3000, SSD-66, PCT-4, or PCT-8 if used) will also appear on the MC-3000

Series controls, so the user is aware of the system's status at all times without having to be in

front of the rack of equipment. From MC-3000's and MC-3800's, the user can also access other

rooms and turn them on or off, program a source to those rooms, and even adjust the other

room's volume level.

DELTA -88 System Controller • an ADA Bus™ Component • is the heart of the Delta System.

As many as 32 Delta-88s can be stacked together to provide a total of 256 possible rooms/zones.

The Delta-88 can house up to eight cards (RAM-50 Room Integrated Amps, RBM-50 Room Bass

Amps, or VSM-8 Video-follow-Audio Switcher {one per Delta-88 max}). From the front panel,

the Delta-88 permits control of all rooms, room acoustical preset programming, and system

programming. The Delta-88 also provides the power supply for the room amplifiers (RAM-

50s and RBM-50s) and is fully fanned cooled. The Delta-88 can accept up to eight sources for

direct access from any 3000 Series keypad. If video sources are included among these eight

sources for composite video distribution, a VSM-8 Video-follow-Audio Switching Module

will be required so that the video sources' composite video outputs connect to the Delta-88.

When using several Delta-88s to form a system, sources are connected to the first Delta-88 and

the additional Delta-88s are connected to the first Delta-88 with a ribbon cable (System Bus).

This ribbon cable sends balanced audio signals to all other Delta-88s. Composite video signals

will need to be split (use an ISO-V Video Isolation Amplifier) to both Delta-88s' VSM-8s. When

using up to seven audio only sources and as many as eight video sources with the need for

composite video switching and/or keypad control of the video sources, use the VS-3 as an

alternate scrolling input selector (see pages 44-55).

RAM-50 Room Amplifier Modules are used as needed, one RAM-50 for each

room/zone. The amplifier provides 50 Watts per channel and is stable

down to 4Ω. Each RAM-50 also provides: a fixed line-level output for use

with surround decoders (SSD-66 or SSD-66THX Decoders); a variable line-

level output for use with external power amplifiers for greater power (PF-

250, 250W/Ch Amp) or when driving an impedance load below 4Ω (PF-200,

1/2Ω stable power amp); and banana pin speaker jacks. For rooms which

may need more amplification than a single RAM-50 can provide, several

RAM-50s can be slaved off of a main RAM-50 while tracking the same source

and acoustical settings. While a single Delta-88 can hold up to eight RAM-

50s, you can assemble the Delta-88 with exactly the right number of RAM-

50s to suite your particular project. Any unused slots in the Delta-88 are

available for future zones.

RBM-50 Room Bass Amplifier Modules are used for rooms that have a passive

subwoofer. The RBM-50 can be pre-ordered to a specific frequency roll-off

point and provides 100 Watts of subwoofer power stable down to 4Ω. When

using a RBM-50, the signal to the bass amplifier is derived from a RAM-50's

variable line level output. Even though the RBM-50's bass level is set in

software, once set, the bass level will track the RAM-50's volume

(room's volume level). The RBM-50 will take the space of one RAM-50

in the Delta-88. Thus, using one RBM-50 in a single Delta-88, will leave

space in the Delta-88 for up to seven RAM-50 Room Amp Cards.

VSM-8 Video Switching Modules are available for providing com-

posite video-follow-audio switching within the Delta-88. A single

VSM-8 takes a card slot inside the Delta-88. Thus, using one VSM-8

(only one per Delta-88) in a single Delta-88, will leave space in the Delta-88 for up

to seven RAM-50 Room Amp Cards. A single VSM-8 can provide switching of up

to eight video sources to up to seven zones. When using several Delta-88s to make

up a system where each zone requires composite video switching, each Delta-88

will require one VSM-8.

The previous items are used to build a Delta-88. The following components are external to the

Delta-88 and can be used to create a full Delta System.

System & Source AC Control

The Delta-88 is the heart of the Delta System but AC switching of home theater systems,

external power amplifiers, and even the source components must use either an ACC-

3 and DB-9, ACC-48, or ACC-3000.

ACC-3000 Source AC Controller • an ADA Bus™ Component • is used for to provide smart

AC switching to each source. If a source is selected on the Delta-88, the ACC-3000 will

turn it on. This ideal operation extends the life of source components while permitting

true one-button operation of Tuners, CD players, and Cassette Players. Using CDs and

Cassette Players with a timer play function, mere selection of that source from either the

Delta-88 or a keypad will turn on that room, turn on that source, and automatically

engage play. To determine if your source component incorporates timer/play, either

locate a switch marked timer/play or: turn the source on, engage it into play, unplug

the source component while in play, plug the source component back into an AC outlet,

and wait 5-10 seconds. If the source has automatic timer/play, it will resume playing

automatically.

ACC-48 Basic AC Controller can be configured to provide one, two, or three different AC

controlling tasks. Designed as an inexpensive way to

provide AC switching, the ACC-48 has four AC

outlets which are triggered via the 9 pin ribbon cable

that connects to the Delta-88's 9 pin "D" connector.

Each AC outlet has a corresponding jumper pin bank

of eight plugs. These eight plugs determine when

that AC outlet turns on. Furthermore, the Delta-88

has a step in its setup program which sets the function

of its 9 pin "D" connector. These options exist

Option 1 - Source Tracking. When the Delta-88's 9 pin "D"

connector is set to source tracking (in software), the ACC-48's AC outlets will engage on

and off with respect to the sources in use on the Delta-88. Thus an ACC-48 can provide

basic independent AC control of up to four sources. Two ACC-48s could provide basic

independent AC control of eight sources. When using the MT-3000 Multi-Tuner, the

MT-3000 typically acts as three of the eight sources on the system. Therefore, if you only

have three other sources in addition to the MT-3000, a single ACC-48 can be used. The

AC outlet for the MT-3000 would have three jumper pins in it bank in correspondence

with the inputs it takes up on the Delta-88. The remaining three sources will plug into

the other three AC outlets with their respective jumper pin banks set with a single

jumper in correspondence to the sources' connection to the Delta-88.

Option 2 - Zone Tracking. When the Delta-88's 9 pin "D" connector is set to zone tracking (in

software), the ACC-48's AC outlets will engage on and off with respect to a zones use

on the Delta-88. Thus an ACC-48 can provide independent AC control to up to four

zones. This device is used when including a home theater system on a particular zone

or external power amplifier on a particular zone. Please note that the ACC-48 can

handle a 10 amp load. If the total four outlets will draw more than 10 amps, additional

ACC-48s will be needed. You can slave several ACC-48s off of the Delta-88's 9 pin "D"

connector. *When working with a tight budget, a single ACC-48 can be used to provide

all sources on at once AC switching on one outlet with the remaining three outlets used

to provide independent room amplification AC control. **If you are using more than

one Delta-88 and have auxiliary amplifiers on both Delta-88s, you will need one ACC-

48 per Delta-88.

Option 3 - Zone Tracking & Source Tracking. The Delta-88 can be modified to accommodate

a second 9 pin "D" connector which provides only zone tracking. This connector and an

ACC-48 would provide amplifier/theater AC switching. The standard 9 pin "D"

connector would be set to source tracking (in software) and be used with ACC-48(s) for

independent source AC switching.

ACC-3 Single AC Controller is capable of providing a switched AC outlet (two AC outlets

rated at 15 amps per ACC-3) when it receives one of

two low voltage triggers. It is connected to the Delta-

88 using a DB-9 9 Pin "D" to Screw Terminal connec-

tor. If you are using a Delta-88's 9 pin "D" connector

for zone tracking, a single DB-9 is used per Delta-88

with any number of ACC-3s to power large external

amplifiers. Since the ACC-3 has a 15 Amp rating, it

may be more conducive for systems using several

large amplifiers in place of an ACC-48 (10 Amp max).

Source Transport Control

PCT-8 Source Controller • an ADA Bus™ Component • Will control up to eight sources via

IR or Serial Data with 19 transport functions per source. Sources can be programmed

on site. Pre-programmed EEPROM Chips for a particular manufacturer (i.e. Pioneer,

Sony) are available from ADA at an nominal fee. The PCT-8 has two address settings

to correspond to the eight direct source buttons on the MC-3000 Series keypads and has

several additional address settings to track the source selected on a VS-3 for scrolling

input selection and source control.

PCT-4 Source Controller • an ADA Bus™ Component • One PCT-4

will control up to four source components via IR or Serial data

with seven transport functions per source. Sources must exist in

the PCT-4 Library.

PDF-3000 • an ADA Bus™ Component • is used to control and read

Pioneer PD-F100 and PD-F107 100 Disc CD Changers. Using the

CD changers scuzy port, the playing disc and track number will

display on all MC-3000 and MC-3800 keypads listening to that

source. Even if you change discs and tracks directly on the

CD Changer, the keypads will update to the newly selected

disc and track numbers. Up to eight 100 disc changers can

be included on any one system (as direct access sources only

- no VS-3 scrolling source selection) with as many as eight

PDF-3000s. The PDF-3000 will also take the place of a port

on the PCT-8 or PCT-4 for CD Changer Control.

BC-232 • an ADA Bus™ Component • This device permits the ADA Bus™ to interface with

RS-232 components such as, AMX or Crestron Touch Screens, Gefen Systems CD and

Laserdisc Computer Management Software Systems, home

automation systems, personal IBM based computers, and

additional devices capable of controlling or being controlled

via RS-232 Data. New manufacturers are constantly integrat-

ing the latest technologies with the ADA Bus™. Please consult

with ADA regarding a particular application.

MT-3000 Multi-Tuner - 3 Broadcast Sources in One Chassis

MT-3000 Multi-Tuner • an ADA Bus™ Component • is used as up to three broadcast sources

in any configuration (FM/FM/AM, FM/TV/TV, etc.) The MT-3000 fully integrates

with MC-3000 Keypads on the ADA Bus™ to provide complete feedback in the form of

station frequencies with programmable preset labels. When selecting a tuner module,

the keypad will display the same information displayed on the MT-3000. While the MT-

3000 acts as three sources, it has only one AC power cord and will need to be turned on

when either sources 1, 2, or 3 are selected from a keypad. You can turn the MT-3000 on

using either an ACC-3000 or ACC-48. Also see FMA-1 and AMA-1 MT-3000 Tuner

Accessories below.

FMA-1 & AMA-1 • an MT-3000 Accessory • The FMA-1 is a remotely controlled FM Antenna

Preamplifier (not an FM antenna) and works in conjunction with the MT-3000 Multi-

Tuner's FM Tuner Modules. Typically, the FMA-1 is used when the FM antenna is

located away from the equipment mainframe. The FMA-1 should be located near the

antenna location and requires an RF Cable and 2 Conductor/18 Gauge w/Stranded

Shield control cable run from it to the MT-3000. Every time the user changes FM

stations, the FMA-1 is told which frequency the tuner is set for and thereby preamplifies

that particular frequency rather than the entire bandwidth. The end result is a more

finely tuned FM signal, preamplified prior to sending the signal through electronically

noisy environments. The AMA-1 AM Antenna and Antenna Preamplifier works

similar to FMA-1, except the AMA-1 is also an AM Antenna in addition to an antenna

preamplifier. This unit should also be located away from electronically noisy environ-

ments (typically an attic space). When using FMA-1s and/or AMA-1s, you will need

to run individual control cables and RF cables for each FM and/or AM Modules. In

typical Delta Systems, where the MT-3000 Tuner Module format is FM, AM, TV, you

will need one FMA-1 and one AMA-1, each with its own RF and Control Cable run to

the MT-3000. Please note, if you wish to use antenna preamplifiers, you will need one

FMA-1 or AMA-1 for every MT-3000 FM Module or AM Module. If your source format

is FM 1, FM 2, AM, you will require two FMA-1's and one AMA-1, each with its own RF

cable and control cable run to the MT-3000.

MC-3000 Room Keypad • an ADA Bus™ Component • One

keypad is needed per zone and will control source selection,

seven source transport commands, room volume, bass and

treble levels (when a zone is a home theater {using an SSD-66}

the MC-3000 Keypad will control Volume Preset, Time De-

lay, Stereo Enhance, and Mode Selection), room off, and

system off. When keypads have been off for ten seconds, the

keypad will display the time. The MC-3000 also incorporates

an IR Receiver which can be used to IR repeat any source's

original hand-held remote (sources must operate on a 35-

45KHz IR). If the keypad receives sunlight or a great deal of

incandescent light, ADA recommends turning the IR emitter

and receiver off. This can be done once the keypad is installed

since it is software controlled. If you anticipate a problem

with the location of the MC-3000 with respect strong lights or

sunlight, plan to include an IRT-3000 IR Transceiver (single-

gang Decora) somewhere else in the room or relocate the MC-

3000. The IRT-3000 has a filter lens.

The MC-3000 Keypad fits into a

double-gang wall box and is available in Brass, Chrome, Black

Chrome, Black Anodized, or painted White. The wall plates

rest on top of the walls surface and

do not provide any play

once installed into a wall box. Wall boxes will need to be

mounted perfectly square or the keypad, once installed, will

appear crooked.

MC-3000T Table Top Keypad • an ADA Bus™ Component • The MC-3000 all metal Table

Top Keypad is available in Brass, Chrome, or painted black or white, and has a slim

control cord with a modular connector. The box is angled and permits the client to move

the keypad to an optimum position when seated. When using the MC-3000T, you must

plug its slim cord with modular jack into a WPA-3000 Wall Plate Adaptor. The WPA-

3000 fits into a single-gang wall

box and comes unfinished in a

brushed aluminum wall plate

ready for painting or wall paper.

ADA strongly recommends add-

ing an IRT-3000 IR Transceiver

to any room which only has an

MC-3000T when IR repeating is

required. The MC-3000T's, IR re-

ceiver/transmitter is usually

turned off to prevent IR interfer-

ence on the ADA Bus™, since the

MT-3000T is usually on a table

top, underneath a lamp.

MC-3800 Keypad with Numeric Source Control • an ADA Bus™ Component • This control

option permits the client to control source components with twelve additional numeric

transport commands in addition to the MC-3000's seven transport functions. You must

be using the PCT-8 in order to access these additional numeric transport functions. This

keypad also offers six additional buttons for low voltage controls (when using an LVI-

3800 for lighting, screen, curtain control, etc.).

MC-3800 can also be purchased as an MC-3800T

Table Top Control and will require a WPA-3000

Wall Plate Adaptor. The MC-3800 Keypad fits

into a three-gang wall box and is available in

Brass, Chrome, Black Chrome, Black Anodized,

or painted White. The wall plates rest on top of

the walls surface and

do not provide any play

once installed into a wall box. Wall boxes will

need to be mounted perfectly square or the key-

pad, once installed, will appear crooked.

MC-3011 Decora Style Delta System Keypad • an ADA Bus™ Component • The MC-3011

Keypad permits direct access of any source, control of volume, room off, and system off.

In addition to these standard functions, the MC-3011 also permits the

control of five transport commands per source. The first transport

function is accessed when the source button is repeatedly pressed and

typically permits tuner preset skip, disc skip, and cassette skip. The

remaining four functions typically include fast forward and fast

rewind buttons (track skip up and down, tune up and down), stop,

play. The MC-3011

does not include an alphanumeric display or

built-in IR transceiver. LED indicators do show which source is

playing or if a zone is on elsewhere when that room is off. The MC-

3011 is programmed through DIP switches and cannot access infor-

mation or control other rooms like the MC-3000.

MC-3800RF Keypad with Bi-Directional RF Wireless Control • an ADA Bus™ Component

• This control option permits the client to control source components using the MC-3800

in a completely wireless format with full two-way communication and feedback. Using

an RF-3000 Transceiver, the MC-3800RF is housed in a wooden enclosure and comes

with a transformer for recharging. Full recharge time takes 1.5 hours and the MC-

3800RF will run continuously for 2.5 hours (we used a screw driver jammed into a

button to test the batteries real-continuous usage

life). Actual time between recharges will be

significantly longer (several weeks) since the

MC-3800 will automatically time out if no but-

tons are pressed. This keypad also offers six

additional buttons for low voltage controls (when

using an LVI-3800 for lighting, screen, curtain

control, etc.). The MC-3800RF is available with a

Brass, Chrome, Black Chrome, Black Anodized,

or painted White face plate and wooden table-

top box options vary in wood type.

MC-3000 OD • an ADA Bus™ Component • The MC-3000

OD is an all weather outdoor keypad complete with a

twelve character alphanumeric LED display. All func-

tions are identical to the MC-3000 except the MC-3000

OD does not have an IR transmitter and receiver. The

MC-3000 OD fits a Mulberry 30601 Three Gang Out-

door Box and should be sealed to the box with silicon.

For custom source formats, the MC-3000 OD will re-

quire a custom silk screen provided at a nominal fee.

All MC-3000 ODs come in a white wall plate.

MC-0038 Hand-Held Infrared Remote Control • an ADA Bus™ Component

• The MC-0038 is a full function remote control which offers the same

functions as the MC-3800 hard-wired keypads. The MC-0038 is zone

specific in that it is programmed, much like a MC-3800, to control a

specific zone. Yet, unlike the MC-3800, the MC-0038 cannot access any

other room. Since all ADA IR Transceivers, whether they are on the MC-

3000 or IRT-3000, all connect to the same wiring harness, it is the MC-0038

which knows what room it is intended to control, not the IR receiver.

Therefore, if your client requires hand-held control in more than one

zone, specify several MC-0038s. When using an MC-0038, ADA strongly

recommends adding an IRT-3000 IR Transceiver to that room. If the

room has an MC-3000T Table-Top control, you will have to provide an

IRT-3000 and disengage the MC-3000T's IR transceiver.

IRT-3000 • an ADA Bus™ Component • This unit acts as both an IR Receiver

and Transmitter and fits into a single-gang Decora Wall Plate. The IRT-

3000 is the best device for receiving signals from a Delta-88 Remote and

particularly the MC-0038 IR Remote Control. It also works well as a

primary or secondary IR receiver for repeating a source component's IR

signals. This unit includes a Red Filter Lens which cuts down on IR

interference. For rooms with a great deal of ambient light (sunlight or

incandescent light) use an IRT-3000 and turn off the IR Transceiver on

the MC-3000 and MC-3800 Keypads.

Assorted Support Hardware

WH-3000 ADA Bus™ Wire Harness • an ADA Bus™ Component • All ADA

Bus™ Components connect to this harness. The WH-3000 provides fuse

protection for short circuits which incorporate automatic reset. One WH-

3000 is required for every eight ADA Bus™ Components. If you are using

more than eight ADA Bus™ components, add one WH-3000 for every eight

additional devices.

BI-3000 ADA Bus™ Isolators • an ADA Bus™ Component • Isolates devices such

as MT-3000s and SSD-66s from picking up control data

noise. One unit is required for each MT-3000, SSD-66, and

SSD-66THX used in a Delta System. BI-3000s are also used

to isolate different ADA Networks which come into play

with larger more elaborate systems.

LVI-3800 Low Voltage Relay • an ADA Bus™ Component • This device can be used in a

variety of applications.

Option 1 - Zone Source Tracking - The LVI-3800 can be set to track

a specific zones source selection such that an AC controller

for a projector and screen (ACC-3) receives a control signal

to turn on only when a video source is selected. When an

audio source is selected or the zone is turned off, the

projector will turn off. If a projector, screen, or even a TV can

be controlled via a switched AC outlet, the addition of an

ACC-3 permits automatic AC control of the video hardware

when only a video source is selected.

Option 2 - MC-3800 Softkey Contact Closure & Voltage - The LVI-3800 can be set so that the

extra six buttons on the MC-3800 Series controls trigger momentary switches for control

of lighting, curtains, etc. No other wire will need to be run to the keypad and the LVI-

3800 can be located anywhere in the house providing that an ADA Bus™ is run to its

location.

Option 3 - Source Transport Controller - The LVI-3800 can be set to control sources which do

not operate via IR or Serial Data. This application can only be done for one of the eight

sources and would permit as many as seven different functions for that source from the

keypads. These functions are translated to momentary low voltage relay closures

making this package ideal for control of a slide projector or other low voltage controlled

source.

Delta-88 Hand-Held IR Remote • Can be used with the

Delta-88, MC-3000, and IRT-3000 (both have an IR

receiver) - The Delta-88 Remote incorporates 3 Room

Selectors which tells the Delta-88 which zone the

remote wishes to control (zones 1, 2, & 3 only). If the

zone is using the Delta-88's preamplifier stage, you

should specify the Standard Delta-88 Remote Control

overlay. If the zone is using an SSD-66 Surround

Sound Decoder for preamplification, you should

specify the Delta-88/SSD-66 Remote Control over-

lay.

PF-200 Low Impedance Power Amplifier - This amplifier

could be used for any zone with several speakers

pairs. The PF-200 is rated down to 1/2 Ω and is the

perfect amplifier when powering as many as sixteen

8Ω speaker pairs on any one zone. Use an additional

ACC-3 so that the PF-200 powers up only when that

zone is on.

SSD-66 or SSD-66THX Surround Sound Controllers • an ADA Bus™ Component • can be

completely controlled from MC-3000, MC-3800, or MC-0038 controls with full feedback

to the MC-3000 or MC-3800 Keypads. These keypads will display the same information

as displayed on the SSD-66. Since the SSD-66 will act as a zone's preamplifier, the SSD-

66 receives a fixed line-level signal from that zone's RAM-50 card. It is essential, that

when incorporating a home theater onto a zone, the home theater is its own zone with

no other rooms shared on that zone. Furthermore, each home theater must use its own

SSD-66 and each home theater will require a RAM-50 even though the cards amplifier

will not be used. Refer to "ADA's Guide To Home Theater Systems" (4 color brochure)

for selecting the appropriate home theater power amplifier.

Source Input Selection & Control Beyond The Standard 8 Sources

VS-3 Video Switcher (8 In x 3 Out) • an ADA Bus™ Component • can be used to provide

additional source inputs to the standard eight sources the Delta-88 can accept. The VS-

3 has multiple addresses, several of which permit the VS-3 to act as a source to the Delta-

88. This permits a system, loaded with seven audio only sources and up to eight video

sources, to access all fifteen sources from a 3000 Series keypad. The audio only sources

would be labeled what they are on the keypad's buttons. The video sources would all

be accessed through an eighth source button labeled VIDEO. Every time the VIDEO

button is pressed, the VS-3 advances to the next input. To provide the user with a sense

of where they are, the VS-3's display will appear on the MC-3000 or MC-3800 telling the

user what video source is selected to that room. Furthermore, the keypad's transport

buttons would correspond to the selected source (when using a PCT-8 Source IR

Controller for the video sources). Since a single VS-3 has three independent outputs, as

many as three rooms can independently and simultaneously select their own video

source using one VS-3. Each room's keypad will have the VIDEO button programmed

to control a specific VS-3 output and since the VS-3 has several addresses, multiple VS-

3s can be used to provide independent video switching to the entire house. Please note,

that the Delta-88 has only eight source inputs and since these are common to all zones,

special design considerations need to be considered when using the VS-3 as a scrolling

input selector. Several options exist and here are some examples:

Option 1 - The selected video source (can also be an audio only source) is common to all rooms,

no independent simultaneous selection. In this scenario, a single VS-3 is used to expand

the system's source input capability. The VS-3's output is fed back into the Delta-88 on

the same source input number as it is on the keypad (i.e. AUX or VIDEO button). Every

time this button is pressed, the VS-3 will advance to the next source with the keypad

displaying that source's name (off the VS-3) and the transport functions operating that

source (use of a second PCT-8 Source IR Controller). Since the VS-3's output is fed back

into the Delta-88, the signal is common to all rooms which select that source.

Option 2 - The selected video source is independent to specific rooms or all rooms and video

sources are capable of being selected simultaneously. In the previous option, the VS-

3's output is fed back into the Delta-88 and is therefore common to the whole house. To

provide independent and simultaneous selection, you will need to use more than one

output of the VS-3 and perhaps several VS-3s to accommodate the entire house. In these

applications, the video signals and stereo audio signals need to be distributed to each

remote room and each room keypad's VIDEO button would access a specific VS-3 and

VS-3 output. In this option, the TVs need to be switched to an external input to receive

the central sources. If the client wants to hear the audio through the same speakers

which are used for central music, a CCA-20 Current Sensing TV Amp & Speaker

Switcher or a CCS-3 Current Sensing Speaker Switcher should be used to override the

speakers with the output of the TV whenever the TV is on. If the room is a home theater,

a LLS-2 Line-Level Switcher should be used in conjunction with some type of voltage

controller (CCS-4 or LVI-3800) to trip the input to the room's surround decoder from the

fixed output of a room's RAM-50 to the fixed output of the local TV or central VS-3. The

output of the TV might be used instead of the VS-3, because the TV tuner's audio may

need to be decoded in addition to the centrally switched video sources.

Option 3 - This option is a combination of the previous two options such that a single VS-3 can

provide independent direct switching to two rooms using the VS-3 outputs 1 & 2 (i.e.

Theater and Master Bedroom) while the rest of the house accesses a common non-

simultaneous (independent) output of the VS-3 (output 3). The two independent rooms

wire as in option 2 and the whole house wires as in option 1.

Option 4 - Using the VS-3 as a scrolling selector to gain transport control of video sources even

though the video sources are being modulated for distribution throughout the house.

In this application, the home could be broken into three areas when using one VS-3, to

gain independent control to the video sources over three areas simultaneously. Again,

this option could also be expanded using several VS-3s such that each room can access

a video source for keypad control independently of all other rooms.

Please note, ADA will introduce additional products which will operate with the Delta System.

Consult with your installer or ADA to find out what new products are available.

Description of the DELTA System (cont.)

Audio Inputs

When looking at the rear panel of the Delta-88, the far right card is the

AIB-50 Audio Input Board. When stacking several Delta-88s to accommo-

date additional zones, only the first Delta-88 will have an AIB-50. The

remaining Delta-88s will have a blank panel and receive the sources line-

level audio signals via a 34 pin flat ribbon cable which is called the System

Bus. The System Bus connection is left unused in a system using only one

Delta-88. The AIB-50 contains a total of eight stereo RCA jacks and is labeled

for sources 1 through 8 corresponding to the Delta-88's front panel sources

1 through 8 reading left to right. The sources' audio outputs connect directly

to the AIB-50 in the appropriate order. Please note, if you do not have a full

compliment of eight sources, take care to connect the sources on the

appropriate RCA jack.

Video Inputs

To permit the greatest flexibility for system design, the Delta-88 does

not come with a video switcher in its standard form. Because cards are added

only as needed, the Video-Follow-Audio Switching Module (VSM-8) is

available as an option. Only one VSM-8 is required per Delta-88 Chassis and

it can switch video to as many as seven zones. It is important to note, that the

VSM-8 takes the place of a zone's room integrated amp card (RAM-50) and

including a VSM-8 in a Delta-88 will leave space available for only seven more

zones.

In most systems which

require two or more

Delta-88s, only a hand-

ful of rooms may actu-

ally require video

switching. If for example, in a home

with 15 zones, perhaps only six or seven

of the zones have TVs. It is suggested to

group these zones with TVs on the first

Delta-88 with the VSM-8 card, while the

rooms that do not require video switch-

ing be grouped on the second Delta-88

that does not include a VSM-8 card.

When connecting video sources to the

VSM-8, please note that the numeric

inputs silk-screened on the VSM-8 panel

are slightly different from the AIB-50

Audio Input Board.

Fixed Audio Line-Level Outputs

Each RAM-50 Room Integrated

Amp Module incorporates a fixed line-

level stereo audio output which can

be used to provide a fixed signal to

surround sound processors (SSD-66

or SSD-66THX). When connecting to

home theater systems, the RAM-50

for that zone acts as the input selector

while the decoder acts as the room's

preamplifier.

In certain cases, you may

be locating the surround

sound processor a signifi-

cant distance from the

Delta-88. When running

the fixed line-level audio

signal an extended distance or near high-voltage wires,

you may experience signal loss or ground loop hums

across the line-level signal. ADA provides two options to

improve audio levels or reduce/eliminate ground loop

hums. The first option includes the use of an ISO-2 Line

Level Isolation Amplifier which buffers the two channels

essentially providing each with its own ground. The

second option involves the use of ADA's XLRX-1 Unbal-

anced to Balanced Line Level Convertor and the XLRR-1

Balanced to Unbalanced Line Level Convertor. Place the

XLRX-1 on the transmitting end of the audio path and the

XLRR-1 on the receiving end of the

audio path. These devices will re-

quire a 2 conductor shielded wire run

for each channel.

Variable Audio Line-Level Outputs

Each RAM-50 Room Integrated

Amp Module incorporates a variable

line-level stereo audio output which

can be used to provide an audio sig-

nal to external power amplifiers (PF-

200 or PF-250). When connecting to

external power amplifiers, the RAM-

50 acts as both the input selector and

preamplifier while its own internal

amplifier is left unused.

Stereo Speaker Jacks on the RAM-50

Each RAM-50 Room Integrated

Amp Module incorporates two banana

jack speaker connectors, one for the

right channel and the second for the left

channel. Please use the banana jacks

that are provided with the Delta-88.

The banana jacks have a small tab on

one of the polls marked GND for

ground. If you wire your speaker cable using the polarity tab as a

ground mark, connection to the Delta-88, even when you cannot

completely see the rear panel, is made significantly easier. Again,

make certain that the bannana jacks connect vertically to both the plus

and minus speaker outputs.

Each RAM-50 is stable down to 4Ω which means it can accept a speaker load of two pair of 8Ω

speakers or one pair of 4Ω speakers. Any load lower than 4Ω will eventually damage the RAM-

50 Amplifier Module. If you are connecting two pair of 8Ω speakers, you can use a second set

of banana jacks to piggyback off of the first set connected to the Delta-88.

Bass Audio Input & Speaker Jacks (Only When Using the RBM-50 Bass Amp Module)

The RBM-50 is designed specifically to drive passive subwoofers with 100 Watts of

power. The subs are receiving a mono

audio signal derived from one of the

other zone amp cards (RAM-50s) on

the same Delta-88. The RBM-50 must

receive a variable line-level audio sig-

nal from the corresponding RAM-50

for that room so that the bass amp

raises and lowers its output along with

the room's other speakers. There are additional settings

in software that permit the bass amps output level to be

set to an initial level. This will be discussed in upcoming

sections of this manual.

Once you have connected a stereo line-level RCA wire from the corresponding RAM-50's

variable line-level output to the RBM-50's loop right & left (it does not matter whether you use

the upper or lower RCA jacks), you can connect the subwoofer's speaker wire to the RBM-50

using the bannana jacks that are provided. Since you can load the RBM-50 down to 4Ω, you

can connect two 8Ω subs to the RBM-50. Again, you can piggyback the second sub on top of

the first subs banana jack.

Composite Video Outputs (Only When Using The VSM-8 Video Switching Module)

The VSM-8 Video Switching

Module has a total of eight composite

video outputs marked 1 through 8.

Actually only seven outputs are used,

since the inclusion of the VSM-8 re-

moves one zone card. The outputs

numbered 1 through 7 correspond to

the first seven room buttons on the

front of the Delta-88 reading left to

right. Connect the composite video

cables to the Delta-88 corresponding to

the appropriate room. Please note that

the numbers on the VSM-8's output are

laid out differently than the AIB-50

Audio Input Board.

In this diagram, the composite video signal is being sent to both TVs in zones 1 & 2. For audio

distribution several options exist and here two are highlighted. In zone one, the fixed line-level

audio signal is also being sent to the room's TV such that when a central video source is selected

on the room's keypad and the TV is set to an external input, the video source appears on screen.

The audio will both come out of the TV's speakers as well as the

room's speakers, with the TV's sound level controlled from the

TV's remote control and the room's sound controlled from the

keypad. In zone two, the TV will only receive the central video

sources video output when set to an external input. The audio

will only come out of the room's speakers using the keypad for

sound level control. Several other audio routing options exist

and are discussed in upcoming sections.

When using a single zones composite video output to drive more than one TV, make certain

to include one ISO-V Video Isolation Amplifier for every additional TV. When more than one

TV is fed a single composite video signal, a wavy interference may appear on both TVs. The

ISO-V allows for a clean split of a single composite video signal and will assist in eliminating

these wavy line forms. Furthermore, if you are running exceptionally long composite video

signals and experience a reduced level of video quality, the use of an ISO-V will improve and

enhance the video image.

AC Connections

The Delta-88 has two AC EIC connectors on its rear panel. The first is for

its own power and is plugged into the ACC-3000 or directly into an AC outlet.

The second is used as a switched outlet to power the PCT-8 (when used) or a

second Delta-88. Connection of the AC lines will be discussed in upcoming

sections.
