Operation
ADJUSTING GAIN
To
adjust the gain setting, turn the amplifier gains all the way down. Turn the source unit volume
up until distortion is audible and then turn it
down
a bit until the distortion
is
inaudible. Next, turn
the amplifier gain setting until once again distortion is audible and then back it down until the
distortion is inaudible.
NOTE: For a more in depth setting procedure, contact Lightning Audio Technical Support.
ADJUSTING CROSSOVER {X-OVER}
Turn the crossover adjustment knob all the way down. With the system playing at normal
listening level, turn the crossover adjustment knob up slowly until the desired crossover point is
achieved.
