Rear Panel Overview (continued from page 2-9)

Note:

The numbered items below correspond with the rear panel illustrations on pages 2-6 and 2-8.

13.Trigger Output Connectors

Provide 12V DC output to control connected components. Three trigger output connectors are available on a removable terminal block. The connector labeled PWR – the power trigger output connector – is not configurable. It is activated when the MC-12 is activated, and deactivated when the MC-12 is deactivated. The trigger output connectors labeled 1 and 2 can be configured for remote or program operation.

14.IR IN Connector

Accepts input of IR signals from infrared distribution equipment. One 3.5mm jack that accepts a stereo plug (Tip/Ring connection) or mono plug (Tip/Sleeve connection) is available.

15.Microphone Input Connectors

Provide microphone input for speaker distance and output level calibration. Four 3.5mm Tip/Ring/Sleeve connectors are available.

16.Removable Access Panel

Accommodates connectors for emerging technologies.

REMOTE CONTROL OVERVIEW

The MC-12 remote control provides full operation of the MC-12, performing commands such as menu navigation that are not available from the front panel. The command matrix that begins on page 2-14 indicates the commands remote control buttons perform when each command bank is activated. The numbered items in the matrix correspond with the remote control illustrations on pages 2-14 to 2-18.

OPERATION CONSIDERATIONS

The bulleted items that begin below describe factors that can improve or impede remote control operation. It is recommended to observe these items as well as the battery installation instructions on page 1-5 before operating the remote control.

Please note the following before operating the MC-12 remote control:

•When the MC-12 is not using the rear panel IR IN connector, the remote control must be in line-of-sight with the front panel IR receiver for proper operation. Eliminate obstructions between the remote control and the IR receiver. The remote control might become unreliable if strong sunlight or fluorescent light is shining on the IR receiver.

•For optimal performance, position the remote control at a 30 degree angle no more than 17 feet (5m) from the MC-12. If the MC-12 is placed inside a glass cabinet, smoked glass will reduce the remote control range.

•Remote controllers for different components can interfere with one another. It is recommended to avoid using remote controls for different components at the same time.

•The remote control batteries should be replaced as needed.
