Operating the W-7
We recommend that you leave your MOON W-7Dual-Mono 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-7will require several hours of playing time before it reaches its peak performance after you’ve powered it up again.
Turning on your MOON W-7 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-7. Finally, power up your W-7in the following manner:
1)On the rear panel, flick the main rocker switch labeled “MAIN 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 W-7is in standby mode.
2)Next, momentarily press the push button labeled “Power” located on the front panel. Your W-7will make a very faint click sound, confirming that everything is in order. The blue LED on the front panel will illuminate, indicating that the W-7is 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 W-7on or off, you should always power up your preamplifier prior to powering up your W-7.As well, always power down your W-7prior to powering down your preamplifier.
Troubleshooting
The blue LED located on the front panel also indicates the operational status of your MOON W-7Dual-Mono power amplifier. In the event that it starts blinking on and off during use, the circuitry is either over-heating or has detected the presence of DC in the input signal:
Left Channel DC protection | LED blinks 2 times |
Right Channel DC protection | LED blinks 3 times |
Left Channel Over-heating | LED blinks 4 times |
Right Channel Over-heating | LED blinks 5 times |
Unknown Problem | LED blinks 6 times |
Your MOON W-7is 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 W-7power 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 W-7via the main power rocker switch, then physically removing all inputs to the W-7leaving only the speakers connected. Attempt to power up your W-7again: 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-7still 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-7. If not, immediately consult your dealer for assistance.
