Operating the Unit
We recommend leaving your 760A 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 760A requires several hours of
operation before reaching optimal performance
after powering it up again.
TURNING ON YOUR 760A 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 760A. 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
760A 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 760A 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 760A on or off,
you should always power up your preamplifier
prior to powering up your 760A. As well, always
power down your 760A prior to powering down
your preamplifier.
TROUBLESHOOTING
The blue LED located on the front panel also
indicates the operational status of your MOON
760A Dual-Mono power amplifier. When the
LED starts blinking on and off during use, the
circuitry is either over-heating or has detected
the presence of DC in the input signal:
DC protection LED blinks 2 times
Over-heating LED blinks 3 times
Unknown Problem LED blinks 4 times
Your MOON 760A is a “smart” power amplifier
equipped with a self-diagnostic system that will
automatically shut itself down when it detects
DC (direct current) from any input. If your 760A
power amplifier turns itself off 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 760A via the main power rocker switch, then
physically removing all inputs to the 760A leaving
only the speakers connected. Attempt to power
up your 760A 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 760A 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
760A. If not, immediately consult your dealer for
assistance.
