Amplifier Manual
1.
Install all system fuses.
2.
Set the amplifier’s input sensitivity controls to
their minimum positions (full counterclockwise).
3.
Set all amplifier signal routing switches
according to your system’s design.
4.
Make preliminary adjustments to the crossover frequency, usually 80Hz is good starting
point for high and low pass. It may be necessary to
fine tune the crossover frequency later for the best
overall sound quality.
5.
If using an XRB1 Remote Level Control, set it to
maximum (full clockwise).
6.
Turn the headunit on with the volume set to minimum.
7.
Visually check the amplifier’s has powered on by the logo lighting blue.
8.
Check the condition of all other components to make sure they are powered up.
9.
Set the headunit’s tone controls, balance, and fader to the center (flat) position. Turn off any
loudness or other signal processing features.
10. Set the volume control of the headunit for maximum undistorted output (on most headunits
this will be approximately 7/8 of maximum volume). Use a very clear and dynamic
recording.
11. Turn up the input sensitivity control until the speakers reach maximum undistorted output.
12. Repeat input sensitivity adjustments for all other amplifiers.
Note: The Exile amplifier’s sensitivity, bass boost and XRB1 Level controls have
no affect on the auxiliary outputs. An amplifier connected to the auxiliary outputs
receives the same signal level available to the Exile amplifier’s inputs (unity gain).
13. Reduce the headunit’s volume to a comfortable level.
14. Listen to various musical selections to check overall system balance. Compare front to rear,
midbass to midrange, etc. If one speaker set is too loud compared to another, then its level
must be lowered to blend correctly with the other speakers. The idea is to reference all
speakers to the weakest set.
Note: For subwoofers controlled by an Exile XRB1 level control, keep the sensitivity setting
from step 11 or 12. Use the XRB1 to blend subwoofers with the rest of the system. The correct
subwoofer volume will change depending on road noise and differences in recordings.
15. Fine tune crossover frequencies to achieve the smoothest possible blending of each
speaker set.
16. Adjust the Bass Equalization Controls on the amplifier, headunit or processor upstream if
necessary to increase output.
Note: Use these controls sparingly. Every 3dB of boost requires double the power at 45Hz. If your
subwoofer system requires a lot of boost to sound good, there may be a problem. Look for out-of-
phase woofers, a leaking subwoofer box, or incorrect box size.
17. With all levels set correctly, the system will reach overall maximum undistorted output at
the volume level set in step 10.
