Adjusting the audio level
For the best performance, you must set LEVEL (MIN/MAX) on the side of the amplifier to adjust
the level of the audio signals.
1.
Use a screwdriver to turn LEVEL(MIN/MAX) fully to MIN
2.
Turn the auto sound system's volume control to about two-third of its full range.
3.
Adjust LEVEL(MIN/MAX) to a comfortable listening level
4.
Turn up the auto sound system's volume control until the sound begins to distort.
Then immediately turn the volume down to a point just before where the distortion
began.
Caution: Never turn up the auto sound system's volume control more than needed to
adjust the audio level, more than two thirds of its maximum volume.
5.
Adjust LEVEL (MIN/MAX) until the sound is at the maximum level you want the
amplifier two produce.
6.
Adjust the auto sound system's volume control to a comfortable listening level.
Trouble shooting
This power amplifier has protection features to prevent any damages from misuse or faulty conditions. If the unit
senses excessive heat, short circuited speakers or overload, the protection indicators will light, and the system will
be turned off. In order to check the occurred problem, you should turn all levels down and all power off and
carefully check the installation for wiring mistakes or short. If the amplifier shuts down due to excessive heat, the
protection indicators will not light: simply allow time for the unit to cool.
