How to Connect
(CONT.)
Using the Trigger In/Out (MC-66/DMA-1240 or DMA-1275):
**
Be sure to power off the controller before disconnecting or connecting Cat5e cables or speaker cables.
**
Trigger In: Only use this input when you want to turn on the controller at the same time another device is turned on. To do
this, the other device must have a low voltage trigger output and be connected to the controller via a 3.5mm mono connec-
tor patch cable. As an example, you might want the controller powered on when you power on a particular CD player. When
the CD player is powered on, it sends a low voltage signal to the trigger input on the controller. When the controller detects
this signal, it powers up out of sleep mode and all of the keypads will power on. IMPORTANT: Please note that while the CD
Player in this example is powered on, the controller and keypads can NOT be powered off.
Trigger Out: Use the trigger output to automatically power up an external device with a low voltage trigger input whenever
a zone is powered on. As an example, with the MC-66 controller, it is often a good idea to connect the Trigger Out to the
Trigger In on the external multi-channel amplifier using a 3.5mm mono connector patch cable. That way, the multi-channel
amplifier will only be powered up when a zone is active. Once all zones have been powered off, the multi-channel amplifier
will return to sleep mode.
On - Auto On - Trigger Switch (MC-66/DMA-1240 or DMA-1275):
For the most energy efficient setting, set this switch to Trigger and connect a 3.5mm mono patch cable from the Trigger Out
on the MC-66 to the Trigger In on the DMA-1240/1275. If a zone is powered on, the low voltage output will be
active which will signal the DMA-1240/1275 to “wake up” and power on. If all of the zones are powered off,
the trigger output will be inactive and the DMA-1240/1275 will automatically return to sleep mode. Please note
that the Power Button on the front of the DMA-1240/1275 should be pressed in with the blue power indicator
light illuminated. Trigger mode, using the included Trigger cable is preferred. We generally don’t recommend
use of the “Auto” setting for this application. “Auto” mode detects the presence of an audio input signal. If that
audio input signal strength is low (as from iPods, MP3 players, computers, and other sources) it can cause the
amplifier to either “turn off”, or not turn on.
Connecting IR Emitters and an IR Receiving Eye
The controller includes the ability to pass infrared (IR) signals on to other components located nearby. This allows the
controller and source components to be located in a centralized (and often hidden) location and still be controlled by the IR
remotes supplied with each of the source components.
The IR signals are sent to the controller either via the IR receiving eyes located on each keypad, or via an IR receiving eye
connected directly to the 3.5 mm input on the back of the controller (the IR input on the back of the controller is a source
passthrough only). The IR signals are passed along to the source components by connecting IR emitters to the back of the
controller and placing them in front of the receiving eyes on the source components. See figure 8.

Use the double-sided tape included with the IR
emitter to attach the emitter to the devices’s IR
recieving eye.
This emitter is attached in the appropriate loca-
tion. The emitter cable is running under this
device to the whole-house audio controller.
This is a side view show-
ing how the IR emitter
should be attached to
the device that is being
controlled.
