On and Off Sequence
To avoid having any annoying noises (ie. “thumps” and
“pops”) emanate from your speakers when powering your
888 on or off, you should always power up your preamplifier
prior to powering up your 888. As well, always power down
your 888 prior to powering down your preamplifier.
Standby Modes
The 888 have two standby modes, the default and the low
power. Both modes prevent the output of signal at the loud-
speaker terminals and turn the front panel blue LED off.
The default standby mode keeps all amplifier stages fully
powered so that the amplifier keeps its optimal working
temperature. The low power standby mode, keeps only
logic control powered, and turn off all amplifier stages. This
saves electricity wasted in heat.
Activate the Low Power Standby mode or not according
to your preference using the switch labeled ‘Low Power
Standby’.
An automatic standby feature is available to turn off
automatically the 888 after 20 minutes of silence. Use the
switch labeled ‘Auto Standby’ to activate this function.
Note : The 12V trigger operation override this function.
Troubleshooting
The blue LED located on the front panel also indicates the
operational status of the MOON 888. In the unlikely event
the LED starts blinking on and off during normal use, it
means it has detected a problem. It is a “smart” power
amplifier equipped with a self-diagnostic system that will
automatically shut itself down if it detects abnormal DC or
overheat. If such situation arise, look at the back of the unit
as one red LED under the label ‘Protection’ will indicate for
which reason, either Thermal (overheating), DC Level, or
other (unknown) the unit has entered Protection mode.
Thermal Protection
If the 888 enters thermal protection, we invite you to turn off
the back panel rocker switch labeled Power and wait for the
amplifier to cool down. Then turn on the unit normally.
DC Level
If the 888 enters DC Level Protection, first power down the
888 via the main power rocker switch, remove physically
the input connection to leave only the speakers connected.
Attempt to power up your 888 again: A successful
power up will indicate the presence of DC coming from your
preamplifier or one of your signal sources (ie. CD Player).
You may then use the switch labeled ‘Coupling’ and enable
AC coupling mode to get rid of the problematic DC, then
connect and turn on the amplifier normally.
Other
If the 888 enters this protection mode, first power down the
888 via the main power rocker switch, and wait one minute.
Then try to turn on the unit normally.
If your 888 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 888. If not, immediately
consult your dealer for assistance.
