Audio Sensitivity Control
The P2100 allows the flexibility of controlling the left and right channel gain for the incoming audio signal. The Sensitivity allows a control of

Sensitivity Trims
To best utilize this feature, set the volume for the source at its fullest output level. Then adjust the left and right sensi- tivity trims on the amplifier to allow the fullest possible out- put from the speakers without distortion.
+6 or a counter clockwise turn is used to reduce the gain. This would be the preferred setting for a distributed audio system with variable preamp line outs, such as the NuVo Essentia system. Reducing the gain can also be useful for limiting the maximum power going to the speakers.
0 or straight vertically is the factory default. This is the pre- ferred setting for an audio signal from a preamp, such as a distributed audio system with a fixed lineout, or the audio output of a music server or CD player.
Power Mode
The P2100 provides three basic methods for supplying power to the amplifier. This can be accomplished by simply push- ing the POWER button on the front of the unit, by sensing an incoming audio signal, or by supplying a

Setting the power mode switch in the left in the AUDIO MODE sets the amplifier to respond to the presence of an audio signal. If you are triggering the amplifier in this way, you should expect a slight delay before it turns on. It will then remain on for approximately three minutes after the incoming audio signal has ended before the unit turns off. This will prevent the unit from inadvertently turning off when the audio signal is very low or stops temporarily.
