21.AC LINE IN: Firmly insert the female end of the AC power cord into this socket. The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power and fre- quency requirements stated on the rear panel. Do not attempt to defeat the safe- ty ground connection.

22.AC LINE SELECTOR: Use this switch to match the unit to the AC line voltage.

23.FOOTSWITCH: Use this jack to con- nect a two-button footswitch to the preamp for remote control of the Mute and Graphic EQ. (Tip controls Mute, ring controls the Graphic EQ.) The front panel switches remain active when a footswitch is con- nected. The front panel Graphic EQ switch (#13) must be depressed for the footswitch to control the Graphic EQ.

24.PREAMP OUTS: Use these jacks to connect the signal from the preamp to your power amplifier, mixing console or house PA system.

25.EFFECTS LOOP RETURN: Use this jack to connect the signal from an external effects processor to the preamp by means of a shielded signal cable.

26.EFFECTS LOOP SEND: Use this jack to connect the signal from the preamp to the input of an external effects processor by means of a shielded signal cable.

27.TUNER OUT: Use this jack to connect the preamp to an external tuner. The signal at this jack is a direct output from the instru- ment. This is the only signal which remains active when the Mute switch (#2) is depressed.

28.PRE/POST: Use this switch to deter- mine whether the signal at the Transformer Balanced Out jack (#29) is pre-EQ (switch in the out position) or post-EQ (switch depressed).

29.TRANSFORMER BALANCED OUT: Use this XLR jack to connect the preamp to an external power amplifier, mixing console or house PA system. The signal at this jack is pre- or post-EQ depending on the setting of the Pre/Post switch (#28).
