MOON by Simaudio
Operating the Unit
We recommend leaving your MOON 330A
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 330A requires several hours of
operation before reaching optimal performance
after powering it up again.
TURNING ON YOUR MOON 330A 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 330A. 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
330A 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 the 330A 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 330A on or off,
you should always power up your preamplifier
prior to powering up your 330A. As well, always
power down your 330A prior to powering down
your preamplifier.
TROUBLESHOOTING
Your MOON 330A Power Amplifier is
equipped with a self-diagnostic system that will
automatically shut itself down when it detects
either DC (direct current) or it enters into thermal
protection mode due to overheating. When
either of these situations occur, the blue LED on
the front panel will begin to blink continuously. If
your 330A power amplifier turns itself off or will
not power up, there may very well be some DC
present in the amplifier’s input coming from your
preamplifier’s outputs. To determine if there is
any DC present power down your 330A via the
main power rocker switch, then disconnecting
the input to the 330A leaving only the speaker
connected. Attempt to power up your 330A
again: A successful power up will indicate the
presence of DC coming from your preamplifier or
one of your signal sources (ie. CD Player). When
your amplifier has overheated, simply wait until it
cools down before attempting to power it back
on again. If your 330A 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 powering up again. 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 330A. If not,
immediately consult your Authorized MOON
Retailer for assistance.
