When running multiple amplifier's in large systems all amplifiers can be linked together so
the primary master amplifier can control all amplifiers. In the following example we show
four amplifiers controlled by one master ampilifer.
Master amplifier's crossover, bass boost
and subsonic adjustments control
for the master and slave amplifiers.
MASTER AMPLIFIER
1.) Set Phase to IN
2.) Set Source to NORMAL
SLAVE AMPLIFIER
1.) Set Phase to OUT
2.) Set Source to SLAVE
SLAVE AMPLIFIER
1.) Set Phase to OUT
2.) Set Source to SLAVE
SLAVE AMPLIFIER
1.) Set Phase to OUT
2.) Set Source to SLAVE
CAUTION!
The amplifiers must see a 1 Ohm load or higher for the subwoofer(s). Any lower
than the above mentioned impedance will cause the amplifiers to overheat and possibly cause
permanent damage to the amplifiers.
