4. Mode & Buttons

Scroll to the previous and next available listening mode,
auditioning listening modes with the current Main Zone input
source. Scrolling occurs in the order shown on the MODE
ADJUST menu. Pressing the Mode button scrolls upward
through available listening modes, and pressing the Mode
button scrolls downward through available listening modes.
Basic Operation
MC-12
2-3
Note:
Power is still supplied to the MC-12 when standby
mode is activated.

2. Front Panel Display

Indicates the current input, listening mode, input source, and
volume level. This 2 x 20 character display can also be used to
view messages and menus, one line at a time.

3. IR Receiver

Receives infrared commands from the MC-12 remote control.
There are three LEDs located in this area as shown below. An
amber LED blinks when a remote control command is received.
A red LED lights when the A/D converters are overloading.
And, a blue LED lights when the MC-12 is powered on and
activated – even if the FRONT PANEL DISPLAY menu STATUS
parameter is set to ALWAYS OFF.
For example, if a 2-channel source is present, the Mode and
buttons scroll through available 2-channel listening modes. The
selected listening mode appears in the bottom-left corner of
the Main Zone two-line status. The MC-12 automatically
activates the selected listening mode when scrolling stops.

5. Mute Button

Mutes Main Zone volume level and restores Main Zone volume
to its original level. Pressing the Mute button once lowers Main
Zone volume level. The message "MUTE ON" appears on the
on-screen and front panel displays. Pressing the Mute button
again restores Main Zone volume to its original level. The
VOLUME CONTROL SETUP menu MUTE LEVEL parameter can
be used to set mute levels.
The amber Mute button LED lights whenever mute is activated,
whether activated automatically or manually. For instance, the
MC-12 briefly activates mute when changing input sources or
listening modes.

6. Volume Knob

Adjusts volume level in all zones.
Note:
When MC-12 output levels have been properly
calibrated, the +0dB volume level setting corresponds
to THX reference levels (75dB).
