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. Up to 11 CT-1 IR Integrators can be combined to
accommodate 21 CT Receivers or 126 zones. The CT-1 can be thought of as the common hub for IR control
of the entire CT system. Each source is connected directly to the CT-1 along with any CT Receivers installed
in the system. All zones will have the ability to control all nine sources when the CT-1 is used.
One CT-1 IR Routing System Integrator provides a system with connections for up to:
One B&K Home Theater Preamplifier or Receiver with Keypads
And
Three CT610/600/310 Multi-Zone Receivers with Keypads
And
Nine shared sources.
Some additional features and benefits associated with the CT-1 are as follows:
1. Multiple CT Receivers are flawlessly controlled using IR from any or all of the CT610/600/310 multi-
zone receiver keypads.
2. The B&K Home Theater CK1.2 Keypad or SR10.1 Remote control can be programmed to control any
source or zone in the system.
3. Up to 7 non-identical sources can be shared between the Theater Zone and the rest of the house
zones. The entire system can also be controlled directly from the Theater Zone using the CT-1.
4. Any keypad in any zone can be programmed to control any other zone, including the B&K Home
Theater and Whole House.
5. In the case that additional zones wish to be added, the CT-1 allows for easy future hardware
expansion of additional CT Receivers and source gear.

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. When connecting
multiple CT Receivers to the CT-1, always connect all nine emitters to insure proper IR routing. When any
zone is using the Dedicated input (IN A, IN B, etc.) or the tuner, IR Out #9 is used.
Each CT Receiver needs to be provided with an emitter attached to the front panel. This emitter allows IR to
be sent back to any of the CT Receivers in this system, thus allowing keypads from any CT610/600/310 to
control any or all of these 18 zones.

Source Emitter Connections
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.
CT-1 Power Connection - 12VDC
Power can be supplied to the CT-1 through any 12VDC (30mA -100mA) power supply. To simplify installation,
utilize the 12VDC power supply from one of the CT610/600 or 310's in the rack. Additionally connect the RS-
232 transmit from the master CT610/600/310 for potential RS-232 communication to a theater receiver or
preamplifier. If RS-232 control is not desired, then the RS-232 portion does not need to be connected.
If RS-232 is not needed, or if all zone keypad ports are being used, then use the 12VDC supply from the
common control +12V and ground.

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 advanced installations, both forms may be required. The following diagrams
depicts both IR or RS-232 being used to control the home theater product.
The illustrations below will also allow for sources that are only used in the theater zone. Control of those
sources is maintained through the theater keypad or IR sensor. Set the DIP switche(s) to pass IR an un-used
IR flasher output. Otherwise the theater receiver/processor Control Outputs can be set to pass IR.
You may not need both forms of communication connected, only connect what you need.
IR = 1/8” mono mini jack
RS-232 = CAT5 straight through cable
The Home Theater sensor plug (three position phoenix) can be used either for a Keypad (CK1.2) or for an IR
sensor located in the theater room. RS-232 XMIT ports on the CT Receiver back panel are outputs only.
RS-232 Data (BKC-DIP) can be obtained from any zone RS-232 XMIT pin.
B&K RS-232 (BKC-DIP) Information
The CT610/600/310 automatically generates a RS-232 (BKC-DIP) message whenever a B&K IR
command is received. A RS-232 (BKC-DIP) message will not be generated if the IR is not a B & K command.
This RS-232 information is transmitted out the CT Receivers six RS-232 XMIT pins and main RJ-45 jack. In
order to control your home theater piece using RS-232, the IR information must be received through the CT
receiver. Once the IR is received by the CT receiver, a RS-232 (BKC-DIP) message will be generated and
transmitted to control the home theater unit. The theater zone now becomes integrated part of the CT system
via RS-232. The generated RS-232 (BKC-DIP) messages only control functions associated with the home
theater processor. These RS-232 (BKC-DIP) messages will not control non-B&K source pieces.

Non-Identical Shared Sources with a Theater
The following diagram illustrates a CT600 and an AVR507 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. RS-232 is illustrated here
because it has a less susceptible to outside interference (i.e. plasma, florescent light, etc.). All nine IR
Flashers should be connected from the CT Receiver to the CT-1. Emitters are connected from the Flasher
output(s) to the front panel of the source device(s). Any component video and digital audio signals should be
connected directly to the AVR507 since the CT does not process either type of signal. The buffered outputs
on the CT Receiver pass the analog audio and composite video signals to the AVR507. Also, a CK1.2
Keypad can be used in place of an IR sensor in the home theater room if use of a remote controller is
desired. This example provides full control over both the Main Home Theater zone and the sources used in
the Theater zone.
Using this system example, if a source is not intended to be "shared" with the rest of the house, control of
that source from the keypad is accomplished by simply connecting an emitter from an un-used FLASHER
OUT on the CT-1 to that source. Set the dip switch accordingly, see section below.
DIP Switch Routing
In the diagram above, the DVD is located on INPUT 2 of the CT Receiver. DIP
switch number 2 needs to be switched ON (up) in order for the IR signal to pass from
the theater keypad or IR sensor to the DVD player. Whenever a DIP switch is set to
ON, it is merely allowing IR to pass from either of the Home Theater IR inputs to the
selected Flasher Outputs. Identical sources cannot be shared between a home
theater and a CT Receiver using this connection method.

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 IR control of the entire CT system and each of
the nine shared source devices. Each additional CT-1 uses one of the three CT FLASHER IN sections on the
CT-1. Each multi-linked CT-1 will accommodate a maximum of two CT receivers (See diagram below). Using
this method will allow IR routing from any of
the 126 potential independent zones to any
of the nine shared sources. The diagram
shown to the right illustrates six CT
receivers linked together (36 stereo zones).
Always connect all 9 IR flashers from the
CT receiver(s) to the CT-1. This is needed
for proper IR routing when the dedicated
inputs or the tuner is selected.
Notice that IR is passed between CT-1s
using the CHAIN OUT to CHAIN IN 1/8” mini
jacks. Therefore, IR data passes from CT-1
#1 to CT-1 #2 to CT-1 #3. Additional CT-1s
can be added at the bottom of this chain by
continuing the method shown. Source
devices are always connected to the last
CT-1 in the chain. A maximum of 11 CT-1s
can be chained together.
IR data cannot be passed “up” the chain of CT-1s (from #3 to #1). Keypads that are programmed with whole
house control (code 000), need to be connected to CT Receiver #1 or #2 in this example. Keypads that
intended to control other zones in the house will only have the ability to control zones located downstream of
where that keypad’s IR signal is entering the chain.
Please refer to our website for additional information pertaining to specific installation scenarios and
programming the system keypads.
