Congratulations on the purchase of the US Audio P-12 power amplifier. The P-12 is a

and headphones.

Front Panel

Channel and 2 volume controls

These knobs vary the amplifier output level.

When this switch is in the speaker position (out) the speaker out terminals on the back

headphone jack on the front panel and the XLR connector on the back panel are active
