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 oper-
ate 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
(475 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.

COMMON
CTRL I/O
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) out-
puts 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 degrada-
tion 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.
