Kicker Impulse 654xi User Manual

Adjustments and Controls
Setting Gain Control
The gain control is provided for level matching purposes. The control does
not give the amplifier any .more power by turning it up. Its purpose is to adjust
the sensitivity of the amplifier in relation to the output level provided by the
source.
Start with the amp gain set to minimum by turning the control counter¬
clockwise. Turn the source level up until distortion is barely audible. Then turn
it down slightly. This will typically be at about 85% to 95% of full volume. Raise
the amplifier gain until distortion is just audible. The gain is now set correctly.
Check the level with cd/tape and tuner to make sure the adjustment is
correct for all sources.
Setting KICKEQ ™ Controls
The Bass and Treble controls on your Impulse Amplifier are provided to help
tune your system for ideal sound quality. After the system is installed and the
vehicle is put back together, do a listening test with music that is typical of
the type you normally listen to.
Initially set the tone controls on the source unit to flat and turn the
KICKEQ ™ controls fully counter-clockwise. Depending on your personal taste
and the speakers used in the system, you may want to increase the high or
low frequencies by turning the KICKEQ ™ controls clockwise. Remember that
once the vehicle is in motion there will be an apparent loss of bass due to the
masking effect of road noise. Do not attempt to make adjustments while the
vehicle is in motion. It is safer to pull off the road to make changes.
Never change the crossover settings while the amplifier is on. A loud pop will
result which could destroy speakers or cause hearing loss.
