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.
