"Balance Output" (Balanced Quarter Inch Stereo Output)
These Quarter Inch outputs are for sending a balanced level signal to a PA system or recording device.
The level of the balanced output signal will also increase with the "master" volume control. These outputs
are durable and offer a better output signal than the "master" or "booth" outputs.
"Player A/B" (Fader Start Eighth Inch Terminals)
These two eighth inch terminals allow Fader/Remote Start Compatible devices (CD Players, Turntables,
etc) to be connected to the unit using eighth inch fader start cables (not included.) Any connected device
can then be remotely started using the Crossfader (Section 7 "Special Crossfader Related Features.)
"Fader Start" must be switched to the on position for this feature to work properly.
AC In and Power Switch
This mixer will only work with the power supply assembly that comes with the unit. Make sure that the
arrow on the multi-pin power connection is facing upward before inserting the power cable into the mixer
(See illustration below.) The mixer should be switched on after all devices are already connected to
prevent damage to your equipment. A Blue Power LED indicates that the unit has been switched on (See
Section 3 "Meters and Lighting.")
