GAIN control adjusts the amount of level provided at the rear mounted output male XLR jack. Nominal gain is 40dB in mic mode, with the control set at #6.
Headphone jack accepts 30Ω to 600Ω headphones for monitoring signals applied to the headphone amplifier.
PWR button turns the unit on and off.
BATT OK LED illuminates when the unit is turned on and will not illuminate when battery voltage is less than 13VDC.
VOLUME control adjusts the level of the headphones.
MIX control blends the signals from the driver circuit and the LINE IN jack to the headphones.
LINE IN jack accepts balanced or unbalanced TRS line level signal and applies it to the headphones through the mix control for foldback and other applications.
