C 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 880M 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 cancel out 880M Evolution Series Operating the 880M We recommend leaving your 880M powered up at all times to maintain optimal performance When you plan on being away for a few days it may not be a bad idea to power off your amplifier Please keep in mind that once fully broken in your 880M requires several hours of operation before reaching optimal performance after powering it up again Turning on your MOON 880M 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 880M Flick the main rocker switch located on the rear panel labeled POWER t
