Operating the MC-8
We recommend leaving your MC-8 powered up at
all times to maintain optimal performance. When
you plan on being away for a few days, it may not
be a bad idea to power off your amplifier. Please
keep in mind that once fully “broken-in”, your MC-
8 requires several hours of operation before
reaching optimal performance after powering 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. Flick the main rocker
switch, located on the rear panel, labeled “POWER”
to the ‘1’ (on) position. The blue LED on the front
panel will blink for up to 10 seconds while it
achieves standby mode. When it stops blinking and
is not illuminated, your MC-8 is in standby mode.
Next, briefly press the push button labeled
“Standby” located on the front panel. You will hear a
very faint click sound confirming that everything is in
order. The blue LED on the front panel will
illuminate, indicating that theMC-8 is now 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. When an red LED it begins 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.
