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 provid-
ed 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 speakers. 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 sub amplifier gain control up to provide the bass level desired.
Note: As the KICKEQ controls are turned up to provide additional bass or treble, 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 typi-
cal 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.
