  • Page 5: Introduction

    MOON amplifiers are so musically satisfying. The performance of your 330A will continue to improve during the first 300 hours of listening. This is the result of a “break- in” period required for the numerous high quality electronic parts used throughout this amplifier.
  • Page 6: Unpacking

    The 330A uses a large toroidal transformer in its power supply; even though it is well shielded, you should not place this amplifier too close to source components sensitive to EMI, such as turntables, phono preamplifiers and CD Players.
  • Page 7: Rear Panel Layout

    330A Stereo Power Amplifier Rear Panel Layout Figure 1: Rear panel of Moon 330A 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 330A and the connected equipment can result that is not covered by warranty.
  • Page 9: Bridged-Mono Operation

    Figure 3: Bridged-Mono operation of the MOON 330A Stereo Amplifier In the event that you wish to operate the MOON 330A Stereo Power Amplifier as a monoblock amplifier, it can be converted to bridged mode without any complex modifications. Only a MOON XLR-BRIDGE adapter 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.

    In figure 4 we have a MOON 350P Preamplifier and 330A Amplifier connected together via their respective 12V triggers; The 12V trigger output on the 350P is connected to the 12V trigger input on the 330A using a 1/8” mini-jack cable. When you turn on the 350P via remote control (or its Standby button), the 330A will automatically turn on.
