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 (aproximately at 90%).
5. Turn the volume down at the source unit until
the distortion goes away.
6. At the amplifier, 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 amplifier’s gain very high as noise,
distortion and amplifier heat will increase significantly
and amplifier failure could occur.
If Bass Boost is used, keep the Gain setting down.
Setting Bass Boost
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 (aproximately at 90%).
5. Turn the volume down at the source unit until
the distortion goes away.
6. At the amplifier, slowly turn the Bass Boost
control up (clockwise) until you hear a slight
distortion from the speakers.
7. Turn the Bass Boost control back down until
the distortion goes away.
8. When the Bass Boost 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 or increase the amplifier’s gain when setting
the Bass Boost control. Increasing the gain even slightly
will cause the amplifier to heat up and amplifier failure
could occur.
