Congratulations on the purchase of the US Audio P-12 power amplifier. The P-12 is a stereo 12 Watt amplifier capable of producing moderate listening levels through speakers and headphones.

Front Panel

These knobs vary the amplifier output level.

2.Channel and 2 Clip LEDs

These LEDs will light when the P-12 amplifier output is approximately 3dB below clipping. (You will hear audible distortion if the amplifier is run at clipping.)

When this switch is in the speaker position (out) the speaker out terminals on the back panel are active while the headphone jack on the front panel and the XLR headphone jack on the back panel are off. When this switch is in the headphone position (in), the headphone jack on the front panel and the XLR connector on the back panel are active and the speaker terminals are off.
