To use the preferred method of setting the
input gain using a voltmeter or oscilloscope,
begin by turning off the amplifier and
disconnecting all speakers from it. Turn the
gain knob completely off (counterclockwise)
and all crossovers off, or to their least
effective setting. If a remote bass accessory
is connected to the amplifier, turn it
completely on (clockwise). Ensure all EQ
and DSP settings on the source unit such
as bass, treble, fader, seating position etc
are set to linear, flat, center, or off. Turn
on the amplifier. Play a 0dB sine wave
through your source unit and increase the
volume to about 3/4 of maximum. Sine
wave tracks can be downloaded for free
from KICKER.com under the "Support" tab.
Use the 50Hz sine wave to set the gain for
a subwoofer and the 1kHz sine wave for
full-range speakers. Set your voltmeter or
oscilloscope to measure AC voltage. Place
the voltmeter's probes on the amplifier's
speaker output terminals. With the sine
wave playing, slowly turn the gain knob
clockwise and watch the AC voltage on the
voltmeter increase.
