There are several methods of properly adjusting the gain (or sensitivity) setting on an amplifier.
The goal is to achieve the maximum clean output that the amp is capable of delivering.
The following steps are an overview, requiring no additional test equipment:
1. Turn the input level control on the amp to minimum (fully counter-clockwise).
2. Play a tape or CD and turn up the receiver's volume control until:
* you hear distortion on the speakers connected to the amp (this can happen even if the sound is not very loud), or
* you reach about 3/4 volume setting.
3. When you begin to hear distortion, you have exceeded the maximum setting for the volume control on the receiver. Turn the volume down slightly until the distortion is eliminated. This is the highest clean signal available from the receiver.
4. Now you can turn up the input level on the amp to a comfortable volume. If you begin to hear distortion, turn the input level down slightly.
