The Finesse and Power To Please A Household...

The CT Receiver family serve the same goals; it is to bring the same performance and sound quality that B&K

has brought to audiophile home theaters and music rooms to the entire house. The CT Receiver is the new

innovation in automation. The CT Receiver may operate an entire house’s audio/video equipment with a mat-

ter of one touch while still bringing the legendary B&K warmth, dynamics, and detail that make critical listen-

ing possible in every room of the house. The CT Receiver family bring a level of performance that was only

available by separates in the past.

Typically,athree zone CT Receiver is used for systems with one to three stereo zones and the six zone CT

Receiver is used for systems with one to six stereo zones. A CT Receivers delivers 55 watts per channel into

8ohm speakers and up to 85 watts per channel while driving 4 ohm speakers. In addition, CT Receivers may

be linked for use in up to 127 zones configurations allowing 9 shared sources all with independent command

and control.

Please visit B&K on the web at www.bkcomp.com for information on our hand assembled product lines, includ-

ing digital preamplifiers, receivers and high current power amplifiers for the best in movie and music reproduc-

tion. High quality amplifiers start at 125 watts per channel with the option of 2 or 7 channels. B&K also carries

200 watt per channel amplifiers with the option of 1, 2, 5, or 7 channels for the most demanding listener. All

of B&K’s home theater amplifiers are class A pre-driver with a class A-B mosfet output stage in order to sup-

ply the most challenging speakers with massive amounts of driving current. B&K also uses toroidal transformer

power supply, computer grade capacitors, and discrete circuitry, which use 1% metal film resistors to provide

superior dynamics and sound quality.B&K,Simply Better!

CT Receiver Features and Benefits

Separates Performance

The CT Receivers are born from the heritage of twenty years experience in building high current, low distortion,

high-end separates. Every design, concept, and tested part, unifies the critical listening vision, which happens

when the music matters. With a B&K Multi-Zone receiver, any room may get the solid deep bass, the warmth,

and the transparency of B&K. The CT Receiver is built by using 1% Metal Film resistors and computer grade

electrolytic capacitors in order to create precision, linearity and dynamics that will reveal every detail of your

source components. The ultimate reason to own B&K is the astonishing revolution in performance that you will

enjoy. The CTReceiver is available in 17” (standard) and 19” (rack mount) faceplates with a black or silver color

choice.

Built-In Intelligence

The CT Receivers work quietly behind the scenes to provide simple automation and flexibility for everyday live.

The CT Receiver may instantly recall your favorite settings without any additional external automation systems

by using unique Personal Action MacrosTM and B&K's SmartZoneTM system. The intelligence is built-in.

A Single Keypad in Each Room - Multi-Zone From One Central System

The CT300.3 provides three independent listening Zones whereas the CT 600.1/600.3 provides six. In each

zone, the user may select sources, raise/lower volume, adjust bass/treble independently without affecting users

in other zones! The CT Receivers give all the performance and ability that a dedicated stack of high-end sepa-

rates would give a user in each room, without any of the visible clutter. The receiver and all shared sources may

be concealed in a cabinet or rack in one central location. The user only needs a keypad to take control!

Connect Up to Nine Shared Sources

More than any other single feature, the nine input capability frees the system architecture from restriction. Nine

inputs enable your system to grow in the future and accommodate any new technology. Built-in IR routing allows

any of the source components to be identical, yet still be controlled independently without problems.

Video For The Entire House

The CT Receivers incorporate a composite video matrix, delivering a pristine picture to every room in the house.

One touch to your remote control or keypad enables you to select different video sources.

Three AM/FM Tuners Allow Simultaneous Listening to Three Radio Stations

The CT Receiver Family offers a combination of internal AM/FM tuner configurations. The CT 600.1 includes 1

tuner, and the CT 300.3 and CT 600.3 include 3 tuners.

Six Dedicated Zone Inputs

Each zone has its own dedicated local Audio/Video source input. The dedicated inputs have the ability to sense

an audio/video input.Once the audio/video input is detected, the zone will be switched automatically to the ded-

icated input. All the user needs to do is turn on the local source, simple!

CK 1.1 and CK1.2 Keypad Features and Benefits

IMPLY ETTER!

CK 1.1 and CK 1.2 Keypad Features and Benefits

Automation Everywhere!

Automate the Central System with Local TVs and Components

The CK1.2 keypad may control up to twenty devices or rooms with 5 hard buttons and four pages of custom

labeled buttons per device. The CK 1.1 has 4 pages of custom labeled buttons and 5 hard buttons. Each but-

ton on either keypad may be programmed with a single IR command (pre-programmed from the database or

learned) or it may be programmed with a macro with up to 190 steps, which may include IR commands, delays,

and jumps to another page. A vast database of more than one thousand brands instantly programs IR Codes

for most products. B&K Batch Learning does the rest in a fraction of the time of any other system. The CK

1.2 has input synchronization with the zone where it operates. The CK 1.1 and CK1.2 also have RS-232 status

feedback. Macros may be programmed using the fastest macro programming method available (simply click on

the button to make it a macro step). Once one keypad is programmed, the rest of the keypads may be cloned

by downloading the program to each keypad. Each keypad stores its program on an EEPROM, so even if the

power is lost, the memory is still good for up to 10 years.

Point Any Remote Control at the Keypad

The integrated IR pass-through sends the commands of any IR remote control to both local installed compo-

nents and the central system. If your client wants to use a remote control in any room, they may simply point it

at the B&K keypad.

Realtime Status Feedback to Keypads

Both the CK 1.2 and CK 1.1keypads will also display zone status when the backlight button is pressed. Realtime

status feedback includes zone input name or radio station, volume, bass, treble and EQ settings. Additionally,

a12VDC status signal lights up the Green Status LED whenever the zone is on. CK 1.2 also offers RS-232

feedback from the CT Receiver so the keypads will be kept in sync with the source that is selected regardless

of how it was selected (by a remote control, the front panel controls or the keypad itself).

Multiple Keypads In One Zone

Keypads may be used in a daisy chain application to accommodate up to 6 keypads per hardware zone. Any

keypad has the ability to control any zone regardless of whether it is daisy chained (slaved) off another keypad.

Slaved keypads are perfect for large rooms that require user interface at both ends. Keypads may be intercon-

nected and used with up to 1000ft using CAT5-E cable.

CT Front Panel (CT300.3 and 600.1/600.3)

1. Main Power Indicator.

2. Master Power Switch, used to disengage power to the CT Receiver. Normally, this switch is set

to ON (in) which allows the power function of a remote or keypad to power the zones on or off.

While the unit is in SLEEP the electrical consumption is reduced to about 35 watts.

Placement and Ventilation

The CT Receiver incorporates built in power amplifiers and requires at least 3" of free air space above the

unit. If built into a rack, please insert at least one rack space of vent panel immediately above the unit.

Default Operation

The factory default settings of a B&K CT Receiver are designed for simplicity and functionality right out of the

box! Default settings will allow for simple functions such as zone power, volume control, input changing and

video connections to be checked as soon as they are connected. No programming required!

Connection Strategy

Installation of a complex A/V system may be a daunting task at first glance. However, the secret to a great

looking and easy to service installation is to be as deliberate as possible. Make the installation SERVICE-

ABLE as well as neat! Dress the wires in groups according to purpose:

·AC Power lines tied together and attached to the cabinet/rack on the opposite side of the signal

cabling. Any component without enough slack in the power wire to enable rotating it or extracting it

should have its length extended with a dedicated extension cord.

·Speaker wires tied together and attached to the cabinet/rack on the opposite side of AC Power lines.

·Antennas should be routed so that they may be re-positioned later.

·IR emitters should be routed and tied down, but NOT attached to source components. Remember,

emitter position is best done with the system powered up! Emitter wires may safely be run adjacent to

AC Power cables.

·Combine Keypad/IR Sensor cables together with any Dedicated Zone Input cables that originates in

another zone. Tie each Zone Control cable together with its dedicated source. Tie everything

together; make sure there is a service loop of free cable and dress on the opposite side of the AC

Power cables.

·Combine all cables coming from the sources, label each cable and connect them to the nine inputs.

·Combine all buffered outputs and connect to additional preamplifiers/receivers in the system.

·If you are utilizing any external power amps, combine the zone line outputs and connect to each

amplifier in turn.

Always leave enough slack at the ends of the cable so that the CT Receiver may be rotated and pulled out of

the shelf. Do not leave wires tied down so tightly that the components are unable to be rotated or extracted

from the rack.

Power Connections

Speaker Connections for CT Receiver

The CT Receiver connects to speakers using 4 position plug-in Phoenix connectors. Speaker wires are home

run from each zone to the back panel of the CT Receiver. Unplug the connector from the rear of the receiver,

strip the speaker wire approximately ¼" and insert the bare end into the gate on the connector. Use a small

flat blade screwdriver to tighten the con-

nection to each conductor. Connectors

accommodate up to 12-gauge wire.

Make sure to observe polarity as you

hold the connector upside down to con-

nect Left and Right as shown. Two

guide tabs also insure proper orienta-

tion.

AC Power and Line Fuse

Before connecting any A/V cables, verify that the CT Receiver powers up. Check functionality of the receiver by

connecting the AC power cord and powering on the receiver using the main power button, the front panel LED

should now be lighted. After 45 seconds, the receiver has finished it’s boot process. Turn off the main power but-

ton and disconnect the AC power cord. Connect all A/V and other interconnect cables and re-connect the AC

power cord. The CT Receiver connection process should now be complete.

Checking the AC Power fuse:

1. Power off the unit and unplug the power cord.

2. Push up on the fuse release tab.

3. Pull the entire fuse holder out.

4. Remove the fuse from the fuse holder and measure the fuse

with a meter. It is not possible to know if the fuse is

blown by looking at it.

5. The CT 600.3/600.1 requires a 12A Slow-Blow type fuse.

The CT 300.3 requires a 8A Slow- Blow type fuse.

Replace only with fuse of same type and value.

Caution! A blown fuse is usually an indicator of an installation or serv-

ice problem. If the fuse continues to fail, the installer should contact

B&K Components Customer Service at 716-656-0026 or contact an

authorized B&K Service Center for assistance.

Dedicated (Local) Source Inputs

Shared Source Inputs

IMPLY ETTER!

14 Source Connections

Any source that is desired to be shared throughout the system will connect to one of the 9 A/V Source Inputs.

Nine sources may be "shared" throughout any zone in the entire system. Internal tuners in the CT receiver

products do not utilize an input. Each of the nine shared sources should be connected as follows:

Source Connection

Use the analog audio and composite video from the source.

Composite video and analog audio may be distributed

throughout the system. Digital audio may be passed through

the composite video inputs and outputs See Page 15.

Mount the IR Emitter on the front

panel, in front of the IR receptacle

of the source.

Source

CT Receiver

Connection

Plug the analog

audio L&R,

the back panel.

Dedicated source inputs are used for local sources that are dedicated only to that individual zone. Typically

this feature is appropriate for sources that are physically located in the zone, such as DVD players or satellite

boxes in bedrooms or dens. By running well shielded audio and video cable from the local source back to

the CT Receiver, the user may utilize the auto-sense capability, which is built into these inputs. The CT

Receiver will immediately auto-detect the audio or video signal from a Dedicated input and switch that zone

to its dedicated input. By default, this feature is set to on; however it may be turned off to add an additional

manually selectable input for that particular zone. Dedicated source inputs are identified on the back panel

by the zone to which they are associated, i.e. IN A, IN B, etc. When auto-detect is used, the CT Receiver will

store previous state of the zone before the Dedicated input detected a signal. Therefore, when the dedicated

signal is switched off, the zone is returned to its previous state.
