(When the Channel Switch [#7] is depressed, the footswitch switches between the Clean channel and the Distortion channel; when the switch is in the out position, the Clean channel is always active, and the footswitch turns the Distortion channel on and off, allowing you a blend of both channels.)

23.EFFECTS LOOP SEND: Use this jack to connect an external signal processor to the amplifier by means of a shielded signal cable. Connect the other end of this cable to the input jack of the external processor.

24.EFFECTS LOOP RETURN: Use this jack to connect an external signal processor to the amplifier by means of a shielded signal cable. Connect the other end of this cable to the output jack of the external processor.

25.BALANCED LINE OUT: Use this XLR jack to send a balanced line level signal to an external power amplifi- er, mixing board, or recording console.

26.PRE/POST: Use this switch to determine whether the Balanced Line Out signal is Post-EQ (switch depressed) or Pre-EQ (switch in the out position).

27.GROUND LIFT: This switch, when depressed, lifts the ground connection at the Balanced Line Out jack (#25). This may help reduce hum in the Balanced Line Out signal.

28.VOLUME: Use this control to adjust the signal level at the Balanced Line Out jack (#25).
