To prevent shock hazard, all three connections must ALWAYS be used. Connect the MOON W5.3 only to an AC source of the proper voltage; Both the shipping box and rear panel serial number label will indicate the correct voltage. Use of any other voltage will likely damage the unit and void the warranty AC extension cords are NOT recommended for use with this product.
Before setting up your new MOON W5.3, we encourage you to please read this manual thoroughly to properly acquaint yourself with its features. We hope you enjoy listening to the MOON W5.3 Stereo power amplifier as much as the pride we have taken in creating this fine audio product.
The W5.3 uses two large toroidal transformers in its power supply; even though they are well shielded, you should not place this amplifier too close to source components sensitive to EMI, such as turntables, phono preamplifiers and CD Players.
MOON W5.3 Stereo Power Amplifier Rear Panel Layout Figure 1: Rear panel of Moon W5.3 Stereo Amplifier The rear panel will look similar to Figure 1 (above). Each channel has one balanced (differential) input on an XLR connector and one unbalanced (single-ended) input on a RCA connector. There is no switch to toggle from balanced mode to single- ended mode.
“Balanced Operation” on for further information. Do not connect cables to both the XLR and RCA inputs at the same time. Damage to both the W5.3 and the connected equipment can result that is not covered by warranty.
Figure 3: Bridged-Mono operation of the MOON W5.3 Stereo Amplifier In the event that you wish to operate the MOON W5.3 Stereo Power Amplifier as a monoblock amplifier, it can be converted to bridged mode without any complex modifications. Only a Simaudio XLR-BRIDGE Y-cable is required. This custom cable will allow one input signal to be sent to both channels of the amplifier’s inputs, as pictured above in Figure 3.
(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.
The “12 Volt Remote Trigger” can turn the MOON W5.3 Stereo Power Amplifier on or off by a hard wired remote connected to its input. When correctly installed, the system allows the use of both the trigger and the push button to turn the W5.3 on or off.
