MC-12

Basic Operation

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.

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.

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).
