Installation guide
9 10
If your head unit has only one pair of Left and Right
RCA out put jacks, plug them in to RCA input Jacks
1 and 2 of the amplier and set the Input model
switch to the 2CH position.
The amplier preamp circuit will automatically
route the signals to channels 3 and 4 thereby
preserving your Left and Right Balance control
but with no Fade control Front to Rear.
The D100.4 features a unique CLONE FUNCTION to assist in setting up a 2-channel bridged system with perfect gain and
crossover tracking between the speakers. Typically when setting up a system you would need to set up channels 1 - 2 and then
channels 3 - 4 crossovers and gains separately not guaranteeing perfect balance or frequency cutoffs. By using the CLONE
FUNCTION you can control channels 1 -2 from the processed signals of channels 3 - 4 thereby guaranteeing that all 4 channels
are getting identical voltages and have their crossover settings identical at identical frequencies. Here is how you do it:
