CALIBRATION
Setting Gain
1. Turn the gain and bass control all the way
down (counterclockwise).
2. Turn the vehicle on, and make sure the source
unit is turned on.
3. Insert a CD/DVD with undistorted music.
4. Start to increase the volume at the source unit
until you hear distortion (about 90%).
5. Turn the volume down at the source unit until
the distortion goes away.
6. At the amplifi er, slowly turn the Gain control
up (clockwise) until you hear a slight audio
distortion.
7. Turn the Gain control back down until the audio
distortion goes away.
8. When the Gain control is properly set, you
should be able to achieve the maximum
undistorted output with the volume turned all
the way up.
Warning!
Do not set the amplifi er’s gain very high as noise,
distortion and amplifi er heat will increase signifi cantly
and amplifi er failure could occur.
If Bass Boost is used, keep the Gain setting down.
