MOON MC-8 Multi-Channel Power Amplifier

Connecting the MC-8

Prior to making any connections or removing the XLR jumpers, the power amplifier must be turned off and the AC cable disconnected for at least 1 minute.

1.Connect the input cables running from your preamplifier’s outputs, whether balanced or single-ended, to the amplifier’ s XLR or RCA inputs respectively. We highly recommend that you use the balanced XLR inputs (provided that your preamplifier/processor has balanced outputs) to take full advantage of MOON MC-8multi-channel power amplifier’s capabilities. Please refer to the next section “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 MC-8and the connected equipment can result that is not covered by warranty.

Don’t hesitate to use high quality interconnect cables. Poor quality interconnect cables can degrade the overall sonic performance of your system. It is recommended, though not mandatory, to use balanced interconnects between your preamplifier and the MC-8when using long cable runs (i.e. more than 3 meters in length).

2.Connect your speakers, with the cables of your choice, to the MC-8polarity (“+” , “-” ) of the output. Once again, don’t hesitate to use cables can degrade the overall sonic performance of your system.

3.Connect the supplied AC power cable to the IEC receptacle, located on the amplifier’s rear panel. Alternatively, if you wish, you may use a dedicated high-performance NEMA 6-20 type AC cable designed for high current applications. Ensure that the AC wall outlet you use is a NEMA 6-20 with a functioning ground. For the best sonic performance, it is preferable that you plug your MC-8directly into this NEMA 6-20 AC outlet and avoid using an extension cord. In the event that you do not already have a NEMA 6-20 AC wall outlet in your listening room, we strongly recommend that you hire an electrician install one.

4.In order to obtain the maximum performance from your audio system, we strongly recommend that the detachable power cord not come into physical contact with either the interconnect cables or the speaker cables running to and from your MC-8. 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.

Balanced Operation

When using an unbalanced interconnect, the audio signal runs through both the center wire and the shield/ground wire. Any noise picked up by this interconnect (ie. nearby magnetic fields such as an AC power cord) will be reproduced by the amplifier and heard through the loudspeakers. Conversely, a balanced interconnect has three separate conductors; one for the ground and two for the actual signal. These two signals are identical except that one is 180 degrees out of phase with the other. For example, when one conductor is carrying a signal of +5 Volts, the other will be carrying a signal of –5 Volts. When these two inverted signals on a balanced line are input into a differential power amplifier such as the MOON MC-8, 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.
