INITIAL SETUP
Activating the Controls
Press both CCW and CW buttons at the same time for less than three seconds
and release, to activate the controls. The adjustment selector indicator
will light. Use the CCW and CW buttons to move the indicator to the
parameter you wish to adjust. After you've made your adjustments and
the controls have been inactive for more than 30 seconds, the selection-
indicator light will go out and the controls will become deactivated to
prevent unintentional adjustment of the amplifier's controls.

lower display). Turn the rotary controller to select the input connector(s) that will feed
output channels 3 and 4.
