  • Page 3: Congratulations

    MOON amplifiers are so musically satisfying. The performance of your W-3 will continue to improve during the first three weeks of use. This is the result of a “break-in” period required for the numerous high quality electronic parts used throughout this amplifier.
  • Page 4: Introduction

    MOON W-3 Stereo Power Amplifier Introduction Your MOON W-3 Stereo power amplifier incorporates many significant design features to achieve its “world class” level of performance. This is an abbreviated list of the more important features: Proprietary “Advanced Renaissance” Technology which eliminates feedback. The results are as follows: Real-time amplification is achieved since interactions from the speaker back to the amplifier are virtually eliminated;...
  • Page 5: Unpacking And Warnings

    Unpacking and Warning! The MOON W-3 Stereo power amplifier is a large and heavy component that should be removed from its box with care. We strongly advise that you seek another person to help lift the amplifier out of its box, and place it in its final location.

    “-”. The reason for two single-ended RCA connectors per channel is as follows: In the event that you wish to operate the MOON W-3 Stereo power amplifier in balanced mode using RCA terminated interconnects. Furthermore, some preamplifiers invert phase and, as a result, their output signal requires phase correction;...

    W-3. In the event that this can’t be avoided, you should ensure that any cables coming into contact with each other are crossed at ninety degree angles to minimize the contact area.

    Volts. When these two inverted signals on a balanced line are input into a differential power amplifier such as the MOON W-3 Stereo power amplifier, any noise picked up by the interconnect will be eliminated since a differential circuit amplifies only the difference between these two signals: Noise on a balanced interconnect will be equal on both conductors and therefore not be processed.

    Figure 3. One lead from the “Y” adapter should plug into the “+” input of one channel and the second lead must plug into the “-” input of the W-3’s other channel. You must insert the two “dummy” RCA terminator plugs, supplied with your W-3 amplifier, into the female RCA input connectors that are not being used.

    Player). If your W-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.
