B&K Introduction / Overview 1 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 A pre-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! S IMPLY B ETTER! B&K 2 CT Receiver Features and Benefits 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 MacrosTM and B & K 's SmartZoneTM system, 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! S IMPLY B ETTER! B&K CK1.2 Keypad Features and Benefits 3 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. S IMPLY B ETTER!

B&K Installation Considerations 11 Installation Considerations RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION 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. S IMPLY B ETTER! B&K 12 Power Connections 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: C AU T I O N : F O R C O N T I N U E D PROTECTION AGAINST RISK O F F I R E R E P L A C E O N LY W I T H S A M E T Y P E A N D VA LU E F U S E 1. 2. 3. 4. 5. Power off the unit and unplug the power cord. Push up on the fuse release tab. Pull the entire fuse holder out. 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. 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. 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 ZONE A LEFT RIGHT 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.
