1. MRC44 Keypad.
2. Power. Turns the zone ON and OFF. Can be programmed with IR
codes or sequences.
3. IR Sensor. Receives IR from hand-held remotes to control both source
components and the MRC44 system. A Programmable Learning Remote
such as the Xantech URC2 is recommended for integrating the IR
commands of the MRC44 and source components into a single
controller. Compatible with most brands of remote controls, though some
may not be programmable and will therefore only control the source
components.
4. Status Indicator LED. Will indicate zone/system status and will flash as
IR is received at the IR Sensor. These indicators, one for each Keypad,
provide the following Information:
a) Off=Zone OFF
b) Steady Green=Zone ON
c) Flash Green=Zone MUTE
d) Flash Red=IR Sensor INPUT or Keypad OUTPUT
e) Flash Amber=System BUSY
5. LCD Display. When the zone power is ON, the LCD will indicate the
selected source, zone and system status, zone volume level and other
system conditions. The display is automatically backlit when any button
is pressed.
