US Amps AX - Manual (Page 9)

WARNING: All U.S.Amps require a grounded input connection.
DO NOT use ground-loop isolation devices or high/low conversion devices
on the input of your U.S.Amp!
Amplifier Input The amplifier MUST receive input on BOTH RCA jacks for proper
operation.
1
Input Gain is variable from 150 mV to 3 volts for full output. Best results are achieved
by adjusting the control to the lowest setting in relation to the output of the source unit.
2
Low-pass Crossover Control
For the internal amplifier, adjustable from 50 Hz to 500 Hz @ 24dB.
3
Remote Bass Gain A two-position removable plug that accepts the included RBG
control harness to allow the amplifier volume to be controlled from the passenger
compartment.
4
The Magic Switch
The far left "Subsonic Filter" position makes more efficient use of amplifier
power by discarding frequencies below 36Hz.
The center "XOver" defeats the Subsonic Filter tor amplifier operation down to 5 Hz.
The far right "Slave" position defeats all amplifier controls to receive information through the Remote
Bass Gain wires from another "master" amplifier.
This can be repeated as often as necessary with all slave units receiving Identical gain, frequency, and
subsonic functions from the master amplifier.
A single Remote Bass Gain can be connected at any point to universally control the volume of the
entire amplifier bank.
