Operating the 330A
We recommend leaving your Nēo 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 Nēo 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 Nēo 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.
