Adjusting & Tuning - Soundstream Edge Series EGA2160 User Manual

Tuning on the Amplifier
The amplifier automatically turns on a few seconds after you turn your vehicle's ignition switch to
ACC or ON or turn on your auto sound system, depending on how you wired the system. The
POWER indicator on the top of the amplifier lights when the amplifier is on.
Important : Your amplifier requires 30 amps or more of power from your vehicle's battery during
operation. To protect your battery from discharging, do not operate the amplifier
unless your vehicle is running.
Adjusting The Audio Level
For the best performance, you must set GAIN (MIN / MAX) on the side of the amplifier to adjust
the level of the audio signals that enter the amplifier .
1. Use a screwdriver to turn GAIN (MIN / MAX) fully counterclockwise to MIN.
2. Turn the auto sound system's volume control to about one-third of its full range.
3. Adjust GAIN (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 GAIN (MIN / MAX) until the sound is at the maximum level you want the amplifier to
produce.
6. Adjust the auto sound system's volume control to a comfortable listening level.
