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 gains set to minimum by turning the controls counter-
clockwise. Turn the source level up until distortion is barely audible. Then turn the
source down slightly. This will typically be at about 85 to 95% of full volume. Raise
the front amplifier gain control until distortion is just audible in the front speak-
ers. Now the deck is matched to the front amplifier channels. Turn the source
down to a realistic listening level.
Turn the rear amplifier gain control up until the desired front/rear balance is
achieved.
Turn the remote subwoofer control all the way up. Turn the sub gain adjust-
ment on the amplifier chassis up to provide the bass level desired.
Note: As the KICKEQ controls are turned up to provide additional bass or tre-
ble, the overall signal goes up. It may be necessary to readjust the gain controls if
the KICKEQ controls are turned up very much.
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 speak-
ers 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.
