3. For low impedance use COM and 8 O Keep impedance above 8 Q For 70 or 100V speaker lines use COM and 70 or 100V terminals Don t mix the types of speaker connections Only one at the time should be used For 100V operation the minimum impedance has to be 153 O For 70V operation the minimum impedance should be 75 Q 11 Mute control terminals By shorting this terminals the signals coming from inputs 3 and 4 will be muted and the chime will be activated if the chime level has been turned on see 19 12 Ground terminal By connecting external equipment to your MA65 hum noise might occur Connecting this terminal to the functional terminal of the other equipment may reduce this noise A more common solution to get rid of buzz ground loops is to use a ground loop isolator in the signal path 13 Pre amp in out You can send the signal of the preamplifier to an external device such as an equalizer APart PXQ2215 or limiter and feed the treated signal back into the amplifier via the poweramp input When you don t use this feature the RCA bridge should be placed 14 Rec out When you need a copy of the contents you page you can connect this output to any recording device such as tape decks MD recorders VHS recorders etc You can also use this output to feed an extra amplifier When you connect your MA65 pre amp out or record out to a microphone input of another mixing amplifier this input will have signal overload and the sound will be m
