Lanzar OPTIXA6B - Manual (Page 8)

2) USING TWO PAIRS OF INPUTS
When front and rear pairs of input are available, from the source, use the“1/2” and “3/4” inputs,
respectively. Set the INPUTS switch to “FOUR” position to allow the signals to be fed internally
to the SUBWOOFER section to give proper outputs to allow control of fader from the head unit.
3) USING THREE PAIRS OF INPUTS
All three pairs of inputs on OPTIXA6B can be utilized when front, rear and subwoofer pairs of
inputs are available from a pre-amp EQ. Set the SUBWOOFER INPUT switch to” DIRECT”
position to allow independent subwoofer level control from the EQ to allow control of fader from
the head unit. Note that some head units offer independent subwoofer output signals as well.
