Use the FADER switches to select which inputs are active with
respect to their paired output. ON will activate the second input.
for example:
If you are using a single RCA pair of inputs, set all FADER
switches to OFF.
For any amp section being driven by additional RCA input(s), set
the FADER switch(es) to ON.
If you are using all four RCA pairs of inputs, set all FADER
switches to ON.
