The Finesse and Power To Please A Household...

The Receiver family serve the same goals; to bring to the entire house the same performance and sound quality B&K has brought to audiophile home theaters and music listening rooms. A level of performance that up to now could only be achieved by a stack of B&K preamplifiers and power amplifiers. Legendary B&K warmth, dynamics, and detail make critical listening possible in every room of the house. New innovations in automation make operating an entire house full of audio/video equipment a matter of one touch, every time!

Typically, the three zone CT Receiver is used for systems with one to three stereo zones and the six zone CT Receiver is used for systems with up to six stereo zones. The six zone reciever offers 55 watts per channel. The three zone reciever offers 55 watts per channel in all zones. CT Receivers can be chained to accommodate independent control for up to 126 zones with 9 shared sources!

Please visit B&K on the web at www

.bkcomp.com for information on our full line of hand assembled B&K

products, including digital preamplifiers, receivers and high current power amplifiers for the best in movie and music reproduction. High quality amplifiers start at 125 watts per channel in 1, 2, 3, 5, and 7 channel options. For the most demanding listener, our 200 watt per channel amplifiers offer 1, 2, 3, 5, and 7 channel options. All of B&K’s home theater amps are class Apre-driver with a class A-B mosfet output stage to supply even the most challenging speakers with massive amounts of driving current. Toroidal transformer power supply, computer grade capacitors, and discrete circuitry using 1% metal film resistors provide superior dynamics and sound quality. B&K, Simply Better!

CT Receiver Features and Benefits

Separates Performance

The CT Receivers are born into the heritage of twenty years experience designing and building high current low distortion high-end separates. Every design, concept, and tested part, unifies the vision that critical listening happens when the music matters. It doesn't matter where you are or what room you are in. With a B&K Multi-Zone receiver, any room gets the solid deep bass, the warmth, and the transparency of B&K. Extraordinary preamplifier build quality using 1% Metal Film resistors and computer grade electrolytic capacitors lend the CT Reciever preamplifier section precision, linearity and dynamics that will reveal every detail your source components can provide. The ultimate reason to own B &K is the astonishing revolution in performance you'll enjoy. Available in 17” (standard) and 19” (rack mount) black or silver faceplates.

Built-In Intelligence

The CT Receivers work quietly behind the scenes to provide simple automation and flexibility for everyday living. Using unique Personal Action Macros

and B&K's SmartZoneTMsystem, the CT Receiver instantly

recalls your favorite settings without any additional external automation systems. The intelligence is built in.

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

The CT310/300 provides three independent listening Zones, the CT610/602 provides six. In each zone the user can freely select sources, raise and lower the volume, adjust the bass or the treble without affecting users in other zones! All the performance and ability that a dedicated stack of high-end separates would give a user in each room, without any of the visible clutter. The multi-zone receiver and all shared sources can be concealed in a cabinet or rack in one central location. Only a keypad need be seen in any zone!

Connect Up to Nine Shared Sources

More than any other single feature, the nine input capability frees the system architecture from restriction. Now, designs can include multiple CD changers or multi-output hard drives. Nine inputs enables 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 from up to ten video sources (nine shared and one dedicated to each zone).

Twin AM/FM Tuners Allow Simultaneous Listening to Two Radio Stations

The CT Receiver Family offers a combination of internal AM/FM tuner configurations. The CT610 and CT310 include two internal tuners. The CT602 also includes two internal tuners. The CT600 and CT300 include one internal AM/FM tuner.

Six Dedicated Zone Inputs

Each zone has its own dedicated local Audio/Video source input. This input can detect when a source is being played and automatically turn the zone on and/or switch from one of the nine shared sources. All the user needs to do is turn on the local source, simple!

CK1.2 Keypad Features and Benefits

Automation Everywhere! Keypads Automate the Central System with Local TVs and Components

The CK1.2 keypad can accommodate control of up to twenty devices with four pages of custom labeled buttons per device. Each button can be programmed with a single IR command (pre-programmed from the database or learned) or it can be programmed with a macro of up to 190 steps (steps can include IR commands, delays of .1 to 99.9 seconds, 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 CK1.2 also features RS-232 status feedback and input syncing for the zone in which it is operating. Macros can 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 can be cloned by simply downloading to each keypad. Each keypad stores its program on an EEPROM so even if the power is lost, the memory is 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 locally installed components and the central system. If your client wants to use a remote control in any room, they can simply point it at the B&K keypad.

Status Feedback to Keypads

RS-232 feedback from the CT Reciever to the keypads will keep the keypads in synchronization with the source that is selected. The keypad will stay 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). The keypads will also display zone status when the backlight button is pressed. Status feedback includes zone radio station or input name, volume, bass, treble and loudness levels. Additionally a 12VDC status signal lights up the Green Status LED whenever the zone is on.

Multiple Keypads In One Zone

Keypads can 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 have successfully been tested up to 1000ft using CAT5-E cable.

CT610 / CT310 Front Panel

1. The front panel Vacuum Florescent Display (VFD) displays what zone you are controlling.

2. The Volume Control adjusts volume of the displayed zone.

3. Stereo headphones with a standard ¼ inch plug connect here. The receiver must be on and in HEADPHONE Mode for proper headphone operation. Headphone mode available in Zone A.

4. The Master Power Switch is only used to completely power off the CT Receiver. Normally, use the Sleep button to power the CT610/310 on or off from the front panel. There is very low electrical consumption when the unit is “sleeping” (35 watts drawn during sleep).

Keypads connect to the Zone Control terminals on the CT Receiver using CAT-5 cable and/or phoenix

connectors. Composite video is used for video distribution, usually RG-6 or better.

IR Flashers for A/V components are connected to the IR flasher outputs corresponding the their A/V Input number.

Video

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 of a B&K CT Receiver is 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

Connecting a CT Reciever can 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 SERVICEABLE 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 can be 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 can 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 in the ends of the cable so that the CT Receiver can be rotated in its shelf or pulled out of the shelf. Don't leave all the wires tied down so tightly that the components cannot be rotated or extracted from the rack without huge difficulty.

Power Connections

Speaker Connections for CT Receiver

The CT Receiver connects to speakers using 4 position plug-in Phoenix connectors. Speaker wires are all 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 connection to each conductor. Connectors accommodate up to 12-gauge wire.

Make sure to observe polarity as you hold the connector upside down to connect Left and Right as shown. Two guide tabs also insure proper orientation.

Speaker Connections CT310 / 300

The CT310/300 Zone B and Zone C connectors terminate using the 4 position plug-in Phoenix connector. CT310 Zone Aspeakers can be connected either via the same plug-in Phoenix connector or via 5 way binding posts for premium speaker wire. The CT310 Zone A amplifier is 150 watts per channel, CT300 Zone A amplifier is 55 wats per channel. The CT300 does not include binding posts.

AC Power and Line Fuse

Before connecting any cables, verify that the CT Receiver powers up. Check functionality of the receiver by connecting the AC power cord and powering on the receiver with the main power button. When the front panel display lights up, power the system down once it has finished the boot up process. Disconnect the AC power cord at the rear of the CT Receiver for safety. You can re-connect once the system connections are complete.

If you need to check the fuse, follow this procedure:

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. You cannot tell if it is blown by looking at it.

5. Replace only with fuse of same value. CT Receivers use 12A Slow-Blow fuses for main A/C.

Caution! A blown fuse is usually an indicator of an installation or service problem. If fuses continue to blow, call B&K Components Customer Service at 716-656-0026 or contact an Authorized B&K Service Center for assistance.

Keypads connect to the CT Receiver at the Control Terminals. There is a five position phoenix terminal for each of the hardware Zones labeled A-F on the six zone receiver and A-C on the three zone receiver.

Termination of the Keypad cables to the Control Terminals can be done in one of two ways: Strip the keypad cable and terminate five wires to the five terminals of each Zone. If you are using a CAT 5

cable connected to an RJ-45 at the Keypad, there are extra connections for Ground,12V and IR data, (identified by the colors in parenthesis) to utilize the 4 twisted pair. These can be left un-terminated however for maximum signal strength they should be connected. It is not important which wiring standard is used, (CAT5 A or CAT5 B), however the T568B is illustrated here:

If the cables have already been terminated in RJ-45 plugs, order the accessory "RJ-45 to 5 Position Phoenix" (P/N 21419) separately from B&K. Plug the RJ-45 plug into the adapter and screw the adapter in place on the phoenix plug. Be sure to match the labels on the CT back panel to the labels under the pins of the adapter. Additional keypads for any zone can be connected to the slave output on the keypad back panel. Keypads should be programmed in series order starting with the Master Keypad, then slave 1, etc...

Each of the 5 terminals for the keypad control ports are defined as follows:

+12VDC - Use this terminal to power the sensors and keypads for this zone. Each control card is limited to 1 amp capacity per three zones in each vertical array. See the next page for examples.

GND - Use this terminal as a common ground for data, control and power. RS-232 XMIT - This terminal transmits RS-232 (BKC-DIP) information. This pin allows RS-232 status feed-

back to the CK1.2 keypad or other RS-232 capable devices. It can be configured with Tab 11 of BKcSuite.

The CT Receiver cannot receive RS-232 via this terminal. DATA IN - This terminal is an OPTICALLY isolated IR data port feeding both the flasher port of the selected

input (unless routing is set to ALL) and the B&K CT microprocessor for B&K commands. CTRL OUT - The 12VDC 200mA outputs are used to control external amplifiers, relays, screens or devices

that activate when a voltage is detected. The default action is that the voltage is ON when the Zone is ON, OFF when the zone is off. This is controlled by going into the Advanced FULL Setup Tab 9 in BKcSuite. The 12VDC controls can be modified to the following choices:

Zone On - The 12V Control Out is on if the corresponding Zone is on (This is Default). Zone Active - The 12V Control Out will turn on only if the Zone is on AND the CT Receiver can

detect an audio or video signal on the selected input for that hardware zone.

Zone Off - The 12V Control Out will turn on only if the corresponding hardware Zone is off. Selected Input - The 12V Control Out is on only if this input is selected (switched to) by the user.

Note that when this option is selected the input check boxes, in BKcSuite, are active (no longer grayed out). Check the inputs that you want to turn on the Zone Control Out.

Headphone - Only Zone A of a CT610 or CT310 allows you to set the Control Out to be triggered by headphone mode. Setting the Zone AControl Out to enables you to connect a separate Zone A power amp and still have it turn off automatically when the user selects headphone mode from a keypad or remote controlling Zone A. Note: Not all CT Receivers offer headphone jack.

Adding Additional Keypads in the Same Zone.

When rooms are interconnected or are open to each other (for example: interconnecting family room, kitchen, and dining areas are common in many homes) you may opt to expand a zone to include several rooms. Many keypads can be connected in a daisy chain from the master keypad in that zone. The master is the keypad which is home run back to the CT Receiver. To daisy chain keypads, simply connect a CAT5 cable terminated into RJ-45 between the two keypads. All the chained keypads need be programmed separately . Daisy-chained keypads can be programmed for independent zone control using the appropriate code-set.

The home run (master) keypad is connected using the MASTER [IN] on the keypad back panel. From the Master Keypad's SLAVE[OUT] connect to the second keypad's MASTER [IN]. You can continue the daisychain to as many as four keypads per zone control terminal. When programming daisy chained keypads,

each keypad must be programmed separately. Always program chained keypads in series order starting with the Master keypad, then the first slave, etc.

Example Shared Source Connection to a CT Receiver

Shared Source Connections

BK&

SBIMPLY ETTER!

Any source that is desired to be shared throughout the system should be connected to one of the 9 A/V Source Inputs. Up to nine sources can 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:

Use the analog audio and composite video from the source. The CT receiver(s) does not process any digital signals. Composite video and analog audio can be distributed throughout the system.

Mount the IR Emitter on the

front panel, in front of the

IR receptacle of the source.

IR Flasher Emitter Output

Each of the nine shared sources can be controlled from any zone in the system using the CT Receiver built in IR routing circuitry. When the IR Flasher outputs are set to “selected input,” (Default) IR is routed from the keypads in each zone to the corresponding source according to the input selected for that zone. This way multiple identical sources can be controlled without changing the source's IR code. For the system to operate properly, an IR emitter connected to the IR output must correspond to the source input, i.e. IN 6 with IR 6. The IR outputs are compatible with any standard 1/8” (3.5mm) miniature flasher/emitter from Niles, Xantech, Elan, Sonance or Speakercraft, etc. The IR outputs operate at 5V and can supply up to 10mA of current (475Ω internal output resistance). Carrier frequency ranges from 32 kHz to 42kHz. Make sure to use IR shields when working with multiple identical sources in the same rack.

The IR outputs are factory default set for selected input operation thus requiring the device input and IR out to match. Simultaneous or “All Inputs” flash can be configured for the 9 IR outputs using either the OSD menu or BKcSuite. When using matrix video switching (i.e. audio and video from different inputs), IR routing will follow the audio input only for that zone.

Buffered Outputs

Line level, impedance matched, (buffered) outputs are provided in order to pass source signals from one unit to another. Each of the 9 shared A/V inputs has a buffered output. These outputs are buffered in order to minimize signal degradation as the signal passes from unit to unit in series. Essentially they can eliminate the need for Y-cables. The Buffered outputs will primarily be used for sharing of sources between other whole house units or home theater systems.

Zone Line Outputs

Zone line outputs are used to run the audio and/or video into each zone. Composite video outputs supply video to monitors in each zone. Zone A's video output provides access to the on screen display for unit setup. The setup menu is only accessible through composite video output of zone A. Line level audio outputs are supplied for each zone in order to provide a means for external amplification in any zone. These line outputs can be configured either fixed at line level, or variable to match the volume level of the receiver’s internal amplification (see next page). Factory default is set for line level fixed output. An external amplifier can be controlled with the 12VDC control out from the zone that it is connected to. When line levels are set to fixed, audio will continue to output regardless of the zone being off. An external volume control is needed for this application. The video signal will shut off when the zone is shut off.

An example of external amplification and video connection in Zone Ais provided below. Note that the amplifier control voltage is supplied directly from the Zone Control terminal on the CT Receiver back panel. If desired, this control voltage can be supplied from the back panel of the CK1.2 Keypad terminated to the Alternate Master [IN]. The figure below shows the fixed/variable jumper is set to fixed; the wall mounted volume controls will control the externally amplified speakers while the keypad selects the source for the zone. The Keypad controls the volume of the Zone A amp channel.

Dedicated Source Inputs (Local)

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 Reciever, the user can utilize the auto-sense capability built into these inputs. The CT Reciever will immediately auto-detect the audio or video signal from a Dedicated input and switch that zone to its dedicated input. This feature is factory default set on, however it can 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 sources are auto-detected, built in software stores the state the zone was in before the Dedicated input detected a signal, this way when the signal is switched off the zone is returned to its previous state.

Dedicated inputs require a second audio/video home run home from the zone back to the CT Receiver.

Changing Line Level Outputs From Fixed to Variable

An internal jumper is used to change the output between line level fixed or variable. This adjustment is typically useful when using additional external amplification. Open the chassis and locate the blue jumper on the audio card for the Zone Line Outputs. The jumpers are in line with each channel on the back panel. The right position is fixed (F) line level, the left position is variable (V) volume control. When set to variable the volume level of the output is matched with the volume level of the receiver amplifier output. The jumper has the ability to change only the left (L) or only the right (R) side of each zone if desired. Note: When these outputs are set to fixed, the last used source will continue to transmit audio only regardless of the zone being powered off. An external volume control is required for this application.

Local Source IR Control

BK&

SBIMPLY ETTER!

Local IR Source Control

Local source control is accomplished by connecting IR emitters to the Alternate Master [IN] of the keypad. Local control is not limited to one source, as many as four IR emitters can be wired in series directly from the keypad. NOTE: Additional resistance will need to be added when running emitters directly from the keypad. Resistance will vary depending on the distance of the run and the size of the wire used. Typical in line resistance will range from 50Ω for long runs to 150Ω for short runs. 12V Control voltages for local amplifiers or other voltage sensing devices may also be terminated directly to the keypad’s Alternate Master [IN] using the 12V control and ground. If resistance is not added, control of shared sources may be lost.

Multiple emitters should be connected in SERIES!

Most common brands of emitter can be used, however all Emitter output more consistent levels when connected in series. Parallel connections may work “some of the time”. Series connections are recommended for consistent operation!

Standard 2 conductor 16 gauge speaker wire is ideal for long runs from the keypad to a Local TV or device using an IR emitter. Utilizing CAT 5 cable will also work well.

Note: Additional resistance

needs to be added when running a flasher directly off a keypad. Resistance will vary depending on length of run usually between (50ΩΩ- 150ΩΩ). The resistor needs to be wired in series with the flashers. This can either be on the + or - side of the connection. You will know if you need additional resistance if the keypad is not able to control the shared sources connected to any of the 9 IR outputs.

Common Control Triggers

BK&

SBIMPLY ETTER!

Common Control Triggers

The B&K CT receiver line incorporates common control triggers that can be used for whole house events such as telephones and doorbells. Two common controls on the six zone receiver (one on the three zone) allow up to 24VAC or DC voltage sensing. Referred to as Page/Events, typical applications might involve a doorbell and front door security camera. For example, when the doorbell is pressed, the CT receiver will switch all zones to the specified A/V source input that the camera is connected to. The user can specify which zones should or should not respond to either or both Page/Events. Wiring diagrams for specific applications are available through B&K. Please visit our website or contact our Customer Service Department for specific applications. The diagram below illustrates the installation of a front door security camera coupled with a doorbell. The Page/Event is default set to switch to input 8 when a voltage is detected through Common Control 1 IN- and IN+.
