Chapter 4 Operation Section
This dual potentiometer controls the volume of the stereo headphone
circuit. The Headphone Master Control operates the headphones that
are plugged into the front and rear headphone jacks, as well as the
transmitter feed jack.
The operation of the Headphone Master Control does not affect the
operation of the program level or monitor level.
This standard 1/4" stereo phone jack will operate with any impedance
headphones. This jack is identical in operation to the rear jack.
The tip of the stereo jack is the left headphone signal, and the ring of the
jack is the right headphone signal.
