Introduction / Overview The CT-1 IR integrator is the keystone to any multi-CT Receiver install. A single CT-1 can integrate control for up to three CT Receivers, one B&K Home Theater preamplifier/receiver, nine shared sources and one CK1.2 Keypad. The CT-1 uses IR as the communication interface between units, it can also pass RS-232 for control of a Home Theater piece. Should future expansion be desired, a CT-1 easily allows additional CT Receivers to be added to the whole house system.
Safety Precautions Installation Considerations CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN WARNING: to prevent fire or shock hazard, do not expose this unit to rain or moisture. Care should be taken to prevent objects or liquid from entering the enclosure. The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the presence of uninsulated "dangerous voltage" within the product's enclosure that may constitute a risk of electric shock to you.

CT-1 IN MASTER - 5 PIN Phoenix plug for connecting to a CT610/600/310 zone control I/O. +12V - +12VDC power input for the CT-1 GND - Common ground for power and data RCV - Receives RS-232 data to pass through to the RJ45 connector (RS-232 XMIT). NC - No connection NC - No connection 2. RS-232 XMIT (Output)- RJ45 connector used for direct RS-232 linking between a CT Receiver and B & K A/V Home Theater preamplifier/receiver.
CT-1 Back Panel 7. CT 2 OUT - One 1/8" mono mini connector. To be used with an IR emitter for control of a CT Receiver. This output is a sum of IR Data from CT-1, CT-3, Home Theater and Chain IN. 8. Home Theater Routing -On/Off DIP switches determine which of the nine IR FLASHER outputs will emit IR to a shared source from the HOME THEATER IR inputs. These DIP switches will allow IR Data from the Home Theater to control certain shared sources. 9. HOME THEATER IN / OUT - Two 1/8" mono mini connectors.
Single CT-1 Basic Connection Basic CT Receiver Expanded System - Up to 18 Stereo Zones A basic expanded system consists of one, two or three CT Receivers, up to nine shared sources, one CT-1 and one Home Theater product. A basic system can require the use of one CT-1, it allows up to three CT Receivers (or 18 stereo zones) to communicate with one another while also sharing and communicating with common sources. The following diagrams depict how a basic system is connected.
CT-1 Basic Connection Source Emitter Connections Source 1 Source 2 Up to nine sources can be shared in any CT system, not including the dedicated inputs. Source control is provide by installing an IR emitter to the front panel of each source. Each source is connected to the CT-1 according to which CT input it is located on. For example, if the DVD player is located on IN 1 on the CT600, then its IR emitter should be connected to Flasher OUT 1 on the CT-1 and so on.
Connecting a Home Theater Product Connecting a Home Theater Product B & K manufactures Home Theater preamplifier/processors and receiver/processors. Any of these products can be combined to share sources in a CT system. Depending on which form of control communication you wish to use (IR or RS-232) B & K can accommodate either or both. Typically only one form of communication is needed, however for some installations, both forms may be required.
Connecting a Home Theater Product Non-Identical Shared Sources with a Theater The following diagram illustrates a CT Receiver and an Theater Receiver sharing a DVD player. Only one source is illustrated here for simplicity. Use the diagram below to add additional non-identical sources. In this diagram, RS-232 (CAT5) is being used to integrate the AVR507 into the CT system. If IR communication is desired instead of RS-232, refer to the previous page for the IR Connection diagram.
Multiple CT-1 Chaining Chaining Multiple CT-1’s Multiple CT-1 IR Integrators can be combined for very large systems. A total of 11 CT-1’s can be chained together to form 126 independent stereo zones. This allows two way IR control of the entire CT system and each of the nine shared source devices. Each multi-linked CT-1 will accommodate a maximum of two CT receivers with the exception of the first CT-1 in the chain (See diagram). The first CT-1 will supply control to three CT Receivers.
