Type: Installation And Operating Instructions Manual

SPS05 POWERED LOUDSPEAKER

The SPS05 is designed to mount directly onto a flat surface, e.g. a ceiling or dry wall, and will

operate directly from several models of remote transmission systems.

It is supplied complete with a regulated power supply which provides 12 Volts DC @ at least 1A.

The unit incorporates an audio pre-amplifier and an audio power amplifier giving a maximum

output of 6 Watts RMS at 12 Volts DC. The pre-amplifier and power amplifier are in a single

integrated device and may be used with audio signals ranging from 50mVpp to 5000mVpp, with a

nominal source impedance of 600Ω.

An internal sensitivity jumper selects high or low sensitivity (see specifications for details).

The unit may be used directly with balanced line equipment as it’s input is balanced and

transformer isolated. When used in unbalanced mode, the screen of the input cable should be

earthed (this is normally connected to earth by the source equipment) and a link should be inserted

between the Screen pin and the input cold pin.

See example connection drawings later in this

document

CABLING

We strongly recommend that all audio signal cables should be a good quality type, with overall

screen. Failure to use the correct cable type may result in noisy or unusable audio performance.

PLEASE SEE INSTALLATION DRAWINGS LATER IN THIS DOCUMENT.

AUXILIARY POWER and “THROUGH” CONNECTIONS

Each kit includes a separate 12V DC

Linear

power adapter which is specifically intended for use

with the

microphone only

However, since the unit is to be used as a “separate loudspeaker plus microphone” intercom

system, a facility exists to provide the microphone unit with the required 12 Volts DC from the

SPSO5 speaker unit. The audio from the microphone can be routed through the SPS05 unit,

allowing audio both to and from the transmitter to be carried in a single cable (a screened, twin,

twisted pair). This makes cabling simpler as all cables to/from the microphone only go to the

speaker unit

(see sample drawings later in this document)

NOTE: The 12 Volt DC supply output from the speaker unit is current-limited and has independent

reservoir and filter components. It is intended to supply

one microphone only

DO NOT ATTEMPT TO USE THIS OUTPUT FOR ANY OTHER PURPOSE!

Installation instructions and drawings

SPS05

UNBALANCED SOURCE INSTALLATION

The audio cable should be a screened, twisted pair type, although a simple, 2-core microphone

type e.g. RS Stock-Code 365-8703 may be used.

IMPORTANT NOTE!

The screen or drain-wire must be earthed at the

SOURCE EQUIPMENT

end

and

MUST

be connected to the connectors marked “SCREEN”

AND

“INPUT COLD” in the SPS05

unit when using single-ended configuration. The power supply unit supplied in the kit has a floating

0 Volt line and should only be replaced with a similar type.

The 12 Volt DC power should be supplied via a separate cable to the audio cable and needs only

to be a twin core, low-Voltage type. This cable does not require a screen and should ideally be of a

0.75 mm

cross-section or more.

NOTE:-

The 12 Volt DC power cable should be kept as short as possible and, in any event

, no

longer than 10 metres.

BALANCED SOURCE INSTALLATIONS

The system may be installed with source equipment which provides a balanced-line output. These

sources are normally low-impedance (e.g. 600 Ohm).

The audio cable should be of a twisted-pair type with overall screen, such as the Belden “Beldfoil”

range (e.g. RS stock code 207-4716).

IMPORTANT NOTE!

The screen or drain-wire must be earthed at the

SOURCE EQUIPMENT

end

and should be connected at the SPS05 unit when using Balanced-Line configuration. The power

supply unit supplied in the kit has a floating 0 Volt line and should only be replaced with a similar

type.

The 12 Volt DC power should be supplied via a separate cable to the audio cable and needs only

to be a twin core, low-Voltage type. This cable does not require a screen and should ideally be of a

1.0mm

cross-section.

NOTE:-

The 12 Volt DC power cable should be kept as short as possible and, in any event

, no

longer than 10 metres.

IMPORTANT NOTE #1

For installations which use a PC

sound card as the audio source

(e.g. the Heitel remote transmission system)

The

TIP

RING

terminals in the jack plug should be

connected together, the resulting (single) signal wire should

be connected to the “

INPUT H

” terminal of the PCB, the

screen of the cable should be connected to the

SCREEN

terminal of the PCB and a shorting link should be inserted

between the

SCREEN

and

INPUT C

terminals of the PCB.

This is done because the output of a PC sound card is

stereo. However, when a mono signal is present, the left &

right signals arrive at the ouput

in phase

. If you feed these

signals into the PCBs H & C (balanced) input terminals,

the

cancel each other out!

So, if you have installed the

system, and you have no audio,

check that you have

followed these instructions!

MICROPHONE INSTALLATION & CONNECTION

Mounting The Microphone

Ideally, the microphone should be mounted in the ceiling tile of a suspended ceiling. In order to

mount the microphone, remove the chosen ceiling tile and drill a 12mm Diameter hole in the tile,

where the microphone is to be located. Feed the open end of the microphone’s cable through the

front of the tile and thread the plastic washer onto the cable at the rear of the tile. Place the washer

over the microphone’s threaded section, so that it makes contact with the back of the tile. Now

thread the plastic nut onto the cable at the rear of the tile and screw this down on the microphone’s

threaded section and hand-tighten the nut.

Connecting to the Pre-amp &

Line Driver (Model CMPALD03).

The pre-amp/line driver module

is housed in a small plastic

enclosure. It may be attached to

the back of the ceiling tile with

the supplied Velcro patches, if

required. Cable entry is via three

holes pre-drilled into the case.

This device should be wired as

follows:-

J1 (+V In) DC Power supply Positive (+) Terminal

J1 (0V In) DC Power supply Negative (-) Terminal (0V)

J1 (Earth) Earth from external location

J2 I/P H Microphone Head Positive (Hot)

POWERED LOUDSPEAKER AND AVS MICROPHONE COMBINATION

If required, the audio cables to and from the on-site transmitter can be combined into a single 2-

pair, individually screened cable. If this is favourable, the connection details are shown below.

When using this cabling, ensure that the cable type used has an individual screen on each pair!

Below is the diagram showing how to wire the system using this cable format.

This diagram also shows how to connect the system using only the switch-mode power adapter

supplied in the kit.

If this is NOT required

, then omit the wiring to the SPS05 connections marked

“+V OUT” and “0V OUT” and connect the power input terminals of the microphone pre-amp

module to the DC output of the linear power adapter supplied in the kit.

Connect using 2-pair cable

IMPORTANT ! SEE NOTE #1 ON PAGE 5 FOR PC CARD SOURCES

FINAL CHECKS & SETTING UP

SPS05 LOUDSPEAKER

Remove the front cover and locate the jumper switch marked “SENS”. Set this to the position

marked “LO”.

Locate the preset volume control.

Switch on the power to the SPS05 loudspeaker unit and plug it in to the audio source.

While receiving an audio signal, adjust the preset volume control until the sound is at the required

level. If the sound level is not high enough, turn the volume control to a low setting (anti-clockwise)

and set the SENS jumper switch to the “HI” position. Now adjust the preset volume control again

until the sound is at the required level.

If you cannot obtain a suitable level, there is a problem with the input signal path. Check the

installation again.

CMPALD03 MICROPHONE PREAMPLIFIER

The gain of the preamplifier is variable.

Remove the cover of the case and locate the preset Gain control.

The gain of the preamplifier is factory set to give an output which is suitable for most line-level

applications. However, the gain may can be increased or decreased manually by turning the preset

gain control. Turning the control clockwise increases the gain, and therefore the output level, and

anti-clockwise decreases the gain, and therefore the output level.

Adjustment of this control should only be made while monitoring the audio output from the

microphone. Mis-adjustment of this control can lead to an audio output which is too low (quiet) or

may cause distortion of the perceived signal if it is too high.

TECHNICAL SUPPORT

Advanced Visual Solutions Ltd provide full technical support for our products. We have two, fully equipped

“central station” workstations, running the latest version of ADPRO video central gold software and HEITEL

monitoring software. We can therefore connect to ADPRO or HEITEL remote transmitters, providing that

they are on standard PSTN telephone lines (modem), standard ISDN lines (terminal adapter) or standard

ADSL (broadband) connections. We

cannot

connect via a clients’ VPN (Virtual Private Network), as these

are (as the name suggests), private!

We have provided this service free of charge for several years, and at our own expense. It is a service to

assist installation and/or service engineers in locating faults, or to “test” a

working

new installation, prior to

going live to a monitoring centre.

Please do not abuse this facility.

It is NOT there to provide free training to installers or “engineers” who

are not sufficiently qualified or experienced to handle the job!

We do not wish to be placed into a situation where we have to make a charge for technical support, as most

of our customers use this facility reasonably and effectively.

If you need support, please call us on 01442 252280
