MOON MC-8 Multi-Channel Power Amplifier
Operating the MC-8
We recommend that you leave your MOON MC-8 Multi-Channel Power Amplifier powered up at all times to maintain optimal
performance. In the event that you plan to be away from your home for a few days, powering off the amplifier may not be a
bad idea. Once fully “broken-in”, please keep in mind that your MC-8 will require several hours of playing time before it
reaches its peak performance after you’ve powered it up again.
Turning on your MOON MC-8 for the first time
Prior to turning the amplifier on for the first time, make sure that every cable is properly connected to avoid any problems.
Then turn on your preamplifier connected to the MC-8. Finally, power up your MC-8 in the following manner:
1) On the rear panel, flick the main rocker switch labeled “MAIN POWER” to the ‘1’ (on) position.
2) Next, momentarily press the push button labeled “Standby” located on the front panel. Your MC-8 will make a
very faint click sound, confirming that everything is in order. The blue LED on the front panel will illuminate and
flash for several seconds.
Then each red LED on the front panel will illuminate, in sequence, one at a time for
each installed channel, indicating that the MC-8 is powered up and ready for use.
On and Off Sequence
To avoid having any annoying noises (ie. “thumps” and “pops”) emanate from your speakers when powering your MC-8 on or
off, you should always power up your preamplifier prior to powering up your MC-8. As well, always power down your MC-8
prior to powering down your preamplifier.
Troubleshooting
Each red LED located on the front panel indicates the operational status of each channel of your MOON MC-8. In the event
that a red LED it starts flashing on and off during use, the circuitry is either over-heating or has detected the presence of DC
in the input signal:
DC detection ....................................... LED blinks 2 times
Thermal Protection .............................. LED blinks 3 times
Your MOON MC-8
is a “smart” power amplifier equipped with a self-diagnostic system that will automatically shut down any
or all channels when it detects DC (direct current) from any input. If your MC-8 power amplifier turns off one or more
channels or will not power up, there may very well be DC present in one (or more) of the amplifier’s inputs coming from one
(or more) of your preamplifier/processor’s outputs or connected source components. You must determine if there is any DC
present. The best way to accomplish this is by first powering down the MC-8 via the main power rocker switch, then
physically removing thel inputs to the MC-8 leaving only the speakers connected. Attempt to power up your MC-8 again: A
successful power up will indicate the presence of DC coming from your preamplifier or one of your signal sources (ie. CD
Player).
If your MC-8 still doesn’t power up, turn off the main power switch and check the AC fuse. If the fuse appears OK, put it back
in its socket and then try to power up again the usual way. If the fuse is blown, replace it with a fuse of the same rating, and
repeat the above process. At this point, you should be able to power up your MC-8. If not, immediately consult your dealer
for assistance.
