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.
