Marantz MM9360 manual PROTECT indicator, POWER indicator, POWER switch, INPUT LEVEL control

4. PROTECT indicator

The protect LEDs illuminate when the fault monitoring mi- croprocessor has determined that one of the following con- ditions exists:

-Power supply undervoltage

-Power supply overvoltage

-Output overcurrent

-Heat sink overtemperature

-Unacceptable DC output content

-Unacceptable high frequency output content

-AC power interruption

Because the signal processing module processes two channels simultaneously, a fault in one channel will result in a protect condition for both channels processed by the same module, ex. channels 1-2, 3-4, and 5-6 (MM9360 only). Thus there will never be a case where only one of the amplifier channels is shown in protect mode. When a pair of protect LED's are illuminated, internal relays have removed the channel pair's speaker loads from the ampli- fier output and connected the speakers to ground. If the fault is isolated to one module (channel pair), the other channels will remain unaffected.

5. POWER indicator

The blue power LED comes on when the amplifier is fully powered up.

6. POWER switch

Press this switch to the ON position to turn the power on, and to the OFF position to turn the power off. When it is required to remote control the power mode of the amplifier, be sure to leave this switch in the ON mode.

7. INPUT LEVEL control

This control sets the amplifier's output level by adjusting its input level. When two adjacent amplifier chan- nels are switched into bridge mono mode, only the odd number channel level controls (1, 3, 5) determine signal level.

8. STEREO/BRIDGE MONO switch

This switch selects between normal stereo chan- nel mode for two adjacent channels, or bridge mono mode, where two channels are supplied the same signal with the second channel's phase inverted 180°. The speaker is then connected across the (+) red output connections of the two channels, resulting in twice the power to the speaker that either channel could deliver by itself. Since in Bridge Mode both connections have voltage present, never con- nect or touch either speaker wire to ground.
