Preamp Output
A preamp output is provided for optional driving of an auxilary
stereo amplifier or active subwoofer etc. Connection from the
preamp should be by screened audio cable. If utilising the preamp
output facility you may wish to activate the Fader function. This will
allow you to balance the relative output levels between the AMR650
V2.0 and the auxilary component. Move the Fader jumper switch on
the AMR650-A to the the centre and right pins - see page 7.
Independent 24V local power supply
The AMR650 is powered directly from the MCU300 via the Cat5
cable. If your installation has very long cable runs from the MCU300
to the AMR650 V2.0 (greater than 30M) the AMR650 V2.0 must be
locally powered instead. This simply involves plugging an Opus
PSA65U power supply into the local power socket on the AMR650-
A.
