System tuning
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 Remote Level Control, set it to
maximum (full clockwise).
6. Turn the headunit on with the volume set
to minimum. or pair your bluetooth device
and set volume to mininum.
7. Visually check the amplifier's has powered 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 source unit for
maximum undistorted output (on most headunits
/ media devices this will be approximately 7/8 of
maximum volume). Use a very clear and dynamic
recording.
Bluetooth P airing INstructions

11.
Turn up the input level control until the speakers reach
maximum undistorted output.
12. Repeat input level adjustments for all other amplifiers.
13. Reduce the source unit 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.
15. Fine tune crossover frequencies to achieve the smoothest possible
blending of each speaker set.
16. With all levels set correctly, the system will reach overall maximum
undistorted output at the volume level set in step 10.
