MOON W5.3 Stereo Power Amplifier

Operating the W5.3

We recommend that you leave your MOON W5.3 Stereo 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 W5.3 will require several hours of playing time before it reaches its peak performance after you’ve powered it up again.

Turning on your MOON W5.3 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 W5.3. Finally, power up your W5.3 in the following manner:

1)On the rear panel, flick the main rocker switch 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 W5.3 is in standby mode.

2)Next, momentarily press the push button labeled “Standby” located on the front panel. Your W5.3 will make a very faint click sound, confirming that everything is in order. The blue LED on the front panel will illuminate, indicating that the W5.3 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 W5.3 on or off, you should always power up your preamplifier prior to powering up your W5.3. As well, always power down your W5.3 prior to powering down your preamplifier.

Troubleshooting

Your MOON W5.3 Stereo Power Aamplifier is equipped with a self-diagnostic system that will automatically shut itself down when it detects DC (direct current) from any input. If your W5.3 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. You must determine if there is any DC present. The best way to accomplish this is by first powering down the W5.3 via the main power rocker switch, then disconnecting the input to the W5.3 leaving only the speaker connected. Attempt to power up your W5.3 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 W5.3 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 W5.3. If not, immediately consult your dealer for assistance.
