Adding a 7th Zone Using The AVR507/505/50 Second Zone
Sometimes a simple seventh zone is needed for a CT install. If a B&K Home Theater is also being installed,
then the independent second zone can be used for the audio/video switching. Amplification must be provided
for the seventh zone. B&K manufactures two channel amplifiers capable of 55 watts per channel,125 watts
per channel or 200 watts per channel. Control of the Home Theater is accomplished by means of a RS-232
Swap cable. See page 27 for swap cable construction. The CT Receiver flashers should be set for “ALL
INPUTS” (Tab 9 BKcSuite). The keypad for the seventh zone should be slaved off of the closest keypad to the
seventh zone. The keypad for the seventh zone should be programmed specifically with the code-set 002.
Code 002 is default for a B&K Home Theater second zone. See figure below for connection diagram.
Status feedback for the seventh zone will not be possible because the zone is actually located in the Home
Theater processor/receiver. The keypad will be connected to the CT Receiver. However, status feedback will
still appear on the keypad for the zone the keypad is slaved from. To alleviate confusion, the status feedback
to the seventh zone keypad should be disabled. To do so, the keypad transmit ID of the CT Receiver should be
changed. On tab 13 of BKcSuite, change the Keypad Transmit ID to 254(FE). When programming the key-
pads for zones 1-6, set the keypad ID to 254(FE) in the Ck1.2 Keypad editor. You may still program each key-
pad using code-set 128 for zones 1-6. Set the Keypad ID for keypad in the seventh zone to 253(FD). OR cut
the RS-232 wire going to the seventh zone keypad.
Only one source is illustrated for
simplicity. A maximum of 7 non-
identical sources can be shared
between a CT Receiver and B&K
Home Theater product. Additional
sources can be added using the
same connection method.
The figure left shows and
AVR507 being used in a seventh
zone application. Audio and
video are passed to the theater
receiver/processor from the
buffered outputs on the CT
Receiver. Analog L & R are con-
nected to the amplifier from the
ZB audio outputs on the theater
receiver/processor. Composite
video for the seventh zone is con-
nected to the video monitor from
the ZB video output of the theater
receiver/processor. Connect a
swap cable between the RJ-45
jack of the theater
receiver/process and the CT
Receiver. Connect an emitter
from the 7th zone keypad to the
video monitor if IR control of the
video monitor is desired.
*Note: Page/events will not be
active in the seventh zone.
