Basic Operation

5.MODE Switch (continued from page 2-5)

Make sure the amplifier is powered off when the MODE switch setting is changed.

INPUTs and OUTPUTs used in (BRIDGED) mode are labelled in parenthesis. Do not use other INPUTs and OUTPUTs that are not labelled in parenthesis. Connect the positive speaker lead to the positive (red) OUTPUT of the first channel, and connect the negative speaker lead to the positive (red) OUTPUT of the second channel.

6. UNBAL/BAL Switch

Selects between unbalanced (RCA) or balanced (XLR, tip/ring/ sleeve) audio input for each channel. Power the amplifier off or reduce system volume before changing the setting of the UNBAL/BAL switch. If the amplifier is connected to a digital controller such as the MC-12 or MC-8, output levels should be re-calibrated whenever the setting is changed.

7. GROUND LIFT Switch

When set to ON, isolates the ground connection between the audio inputs and the chassis. This can be useful for eliminating audible hum or noise caused by multiple grounding paths in the system. When set to OFF, the audio inputs are grounded to the chassis. This switch should be set to ON whenever there is ground noise present in the system.

WARNING Do not defeat or remove the ground prong on the AC power cord. This will result in a safety hazard, and will not

reduce audible hum. The GROUND LIFT switch has no effect on the safety ground of the amplifier.

8. TRIGGER INPUT

Enables the amplifier to be controlled by the MC-12/MC-8 or other external devices with a 12V DC trigger output. Connect the trigger output of the external device to the TRIGGER INPUT of the amplifer, and set the TRIGGER switch on the amplifier to ON or DELAY. The amplifier will automatically respond when the external device is powered on and off.

9. TRIGGER INPUT Switch

When set to OFF, the amplifier only powers on and off in response to the front panel standby button. When set to ON or DELAY, only the external device connected to the TRIGGER INPUT can be used to power the amplifier on and off. The front panel standby button will not power the unit on and off. (However, the standby LED still functions normally.) When set to DELAY, the normal 5 second power on delay is extended to approximately 7 seconds.

The TRIGGER INPUT Switch setting will not take effect until the amplifier has been power cycled.
