(Shown here is AX-1000, but the diagram is also applicable to AX-2000.)

1Amplifier Input The amplifier MUST receive input on BOTH RCA jacks for proper operation.

2Amplifier Output The low level output can be connected to other amplifiers.

3Input Gain is variable from 1 to 9 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.

4Low-pass Crossover Control

For the internal amplifier, adjustable from 50 Hz to 500 Hz @ 24dB.

5Remote Bass Gain A phone jack that accepts the included RBG control harness to allow the amplifier volume to be controlled from the passenger compartment.

6Low-pass Crossover On/Off Switch

A 2-way switch which enables/disables the low-pass crossover feature.

7Subsonic Filter To optimize amplifier power in the audible frequencies, a defeatable 36 Hz subsonic filter provides a 6 dB per octave roll-off.

WARNING: NEVER use ground-loop isolation on the input of your U.S.Amp! It doesn’t need it!
