17. HEADPHONES: Use this jack to listen to the amplifier through a pair of stereo headphones. The internal speaker is disconnected when the headphones jack is used. To avoid possible damage to your hearing, do not use headphones for extended periods of time at extremely loud listening levels. 18. POWER: Use this switch to turn the amplifier on and off. The adjacent LED illuminates when the amplifier is turned on. 19. ELECTRONIC TUNER (top panel, not shown): This active electronic tuner is on whenever the amplifier is turned on, allowing you constant, �real-time� tuning. The tuner is fully chromatic � use the flat and sharp indicators until the LED between them illuminates, indicating proper tuning.
The Rear Panel:
20. AC LINE CORD (not shown): 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 frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection. 21. EXTERNAL SPEAKER: Use this jack to connect the amplifier to an external speaker cabinet. This jack is wired in series with the internal speaker, which remains active when this jack is used. A 4 ohm external speaker cabinet is recommended.

22. FOOTSWITCH: Connect a two-button footswitch (such as the Crate CFS-2) here for 21 22 25 26 27 28 remote control of the channel selection/�blend� (see #7) and octave on/off. (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 amplifier, 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). 5
