SYSTEM TUNING - BASIC
1. Install all system fuses.
2. Set the amplifier's input sensitivity (LEVEL) controls to their
minimum positions (full counterclockwise).
3. Set all amplifier crossovers according to your system's design.
4. Make preliminary adjustments to the crossover frequency,
usually 80Hz is a 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 a RBPC, set it to maximum (full clockwise).
6. Turn the headunit on with the volume set to minimum.
7. Visually check the amplifier has turned on by the power LED.
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 to maximum volume.
Play music you typically listen to through the system.
11. Turn up the sensitivity or input level control on the amplifier
until the speakers reach maximum undistorted output.
12. Repeat sensitivity level adjustments for all other amplifiers.
13. Reduce the headunit's volume to a comfortable level.
SYSTEM TUNING - ADVANCED
Advanced Tuning (Recommended Method)
1. Disconnect all speaker wires from amplifier.
2. Disconnect RCA's from any other system amplifiers.
3. If using RBPC, turn LEVEL fully clockwise. (Full output)
4. Select a test tone within the range of the output you
are going to connect the amplifier. Highpass (5kHz),
Midrange (1kHz), Bass 80Hz.
5. Adjust source unit to 85% full output and play selected
test tone.
6. With the DMM set to AC voltage, measure output
of amplifier (only one channel per level control is
needed).
7. With test tone playing, slowly turn level control
clockwise until target voltage is displayed on DMM.
(see diagram below)
8. Repeat for all amplifiers/pairs of channels in system.
9. You have now set your amplifier(s) to perform at
maximum output. Do not adjust the level higher from
this point forward. Reconnect speakers.

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.
Note: For subwoofers controlled by the Remote level control,
keep the level setting from step 11 or 12. Use the control 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.
10. Adjust all crossovers and listen to the system.
Level Matching:
If output levels do not match, determine which
speakers are too loud in comparison to the others.
Select the level control to these "louder" speakers
and lower it to match the others. Listen again and
readjust if needed. Do not increase levels higher
than the set point that was determined in step 7. This
method will provide the best dynamic range, exhibit
no distortion and have an ultra-low noisefloor.
Turn LEVEL slowly clockwise until DMM reads target voltage
