General Information and Features
Front Panel
Power Switch: This is used to turn the unit on or off.
LED Indicators: There is one LED indicator for the power
and each zone. When first turning the power on, the
power LED will come on red and then switch to blue to
indicate the amplifier is in a ready mode, if there is no
audio active to any of the inputs approximately 15
minutes later the power light will turn red to indicate it's in
sleep mode. Zone LED lights will come on blue as each
zone senses an audio source to the zone input. In case of
a fault to a particular zone the LED changes to RED. If
the fault remains, the corresponding LED remains red. If
the short circuit is momentary then the zone LED changes
to red and then switches to solid blue after a few seconds.
Once all zones are cleared of faults the front LED's will
turn blue as long as they are active, if no audio source in
present the lights will turn off to indicate the zones are in
sleep mode.
Rear Panel
BUS 1 and 2 Inputs: There are "right" and "left" RCA style
connectors labeled as "1" & "2". These inputs are used
for sending a single audio source (i.e. CD, Tuner, MP3
etc.) to more than one zone.
