Operating the W-3
We recommend that you leave your MOON W-3Stereo power amplifier powered up at all times to maintain optimal performance. In the event that you plan to be away from your home for a few days, powering off the amplifier may not be a bad idea. Once fully “broken-in”, please keep in mind that your W-3will require several hours of playing time before it reaches its peak performance after you’ve powered it up again.
Turning on your MOON W-3 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 W-3. Finally, power up your W-3in the following manner:
1)Flick the main rocker switch labeled “MAIN POWER” to the ‘1’ (on) position.
2)Next, momentarily press the push button labeled “Power”. The amplifier will make a faint click sound, confirming that everything is in order. The blue LED on the front panel indicates that the amplifier is 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 W-3on or off, you should
1)Always power up your preamplifier prior to powering up your W-3.
2)Always power down your W-3prior to powering down your preamplifier.
Troubleshooting
Your MOON W-3Stereo power amplifier is equipped with a self-diagnostic system that will automatically shut itself down when it detects DC (direct current) from any input. If your W-3power 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. You must determine if there is any DC present. The best way to accomplish this is by first powering down the W-3via the main power rocker switch, then disconnecting all inputs to the W-3leaving only the speakers connected. Attempt to power up your W-3again: 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 W-3still 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 W-3. If not, immediately consult your dealer for assistance.
