Stereo Mode:
Stereo mode will play the audio entering the amplifier through the left & right input channels out to
the left & right speakers attached to that zone.
Bridge Mode:
Bridged mode will take the audio entering the LEFT channel of the zone ONLY and send it out of
the outermost ports of the phoenix connector.
Bridged mode will output up to 150w @8Ω.
Bridge mode must see an 8Ω signal, lower than
8Ω will damage the amplifier.
ST/BR Switch (Stereo/Bridge)
Use this switch to change between stereo and bridge mode for each zone.
Crossover Knob for Subwoofer RCA
This knob is used to adjust the crossover frequencies (40Hz to 140Hz) sent out of the “SUB OUT”
RCA jack.
Gain Adjustment
This knob adjusts the output level for each zone independant. Set the input gain control to your
desired level and make sure the speakers are not distorting at very loud volumes.
Ground Lift Switch
If there is a problem with a 60Hz ground loop with this amplifier due to poor house electrical
grounding, this switch can sometimes help eliminate the noise or hum problem that can occur.
Speaker Terminals
These Phoenix type terminal connectors are used to connect the speakers to the amplifier. Max
gauge of speaker wire is 14 AWG.
Anti-Clipping Protection Circuitry
The anti-clipping circuitry will automatically reduce the output level going to the speaker from the
amplifier when it senses the volume is too loud. The RED clipping light will flash until you lower the
source or the input gain control for that zone.
Fault Safety Circuitry
If by accident the speaker wires cross (touch each other) the blue channel LED light for that zone
will turn solid RED. No sound will come from any speakers attached to the faulted wires until you
correct the fault (seperate the touching wires). No damage will come to the Amp.
