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.
