The Rear Panel:

21. LINE OUT: When using an external effects processor, connect this jack to the input of the effect by
means of a shielded signal cable. This jack also doubles as a source for a post-EQ, preamp signal to send
your signal to a mixing board, recorder, powered monitor or external amplifier.

22. LINE IN: When using an external effects processor, connect this jack to the output of the effect by
means of a shielded signal cable. This jack also doubles as a direct connection to the power amp, bypass-
ing the input and preamp stages. This is useful for “slaving” a pair of amplifiers together.

23,24. SPEAKERS: Use these jacks to connect the amplifier to your speaker cabinet(s) using speaker
cables with mono 1/4” plugs. These jacks are wired in parallel. Make sure that the combined impedance
of your speakers is equal to or greater than 2 ohms! Use the chart below to help determine parallel loads.
If in doubt, ask your dealer.

25. SOLO/RHYTHM/CLEAN FOOTSWITCH: Use this jack to connect the 1/4” stereo plug on the
footswitch cable to the three-button footswitch (supplied). This allows you to remotely switch between the
Clean and Distortion channels and between the Solo and Rhythm channels.

26. REVERB FOOTSWITCH: Use this jack to connect the 1/4” mono plug on the footswitch cable to the
three-button footswitch (supplied). This allows you to remotely turn the reverb on and off.

27. FUSE: The fuse protects the ampifier from damages caused by a faulty AC power source and/or other prob-
lems. If the fuse fails, replace it ONLY with the same size and type. If fuses continue to fail, check the AC source
– if the source is okay, contact your Crate dealer for service information.

28. AC LINE CORD (not shown): This grounded power cord is to be plugged into a grounded power outlet, wired
to current electrical codes and compatible with the voltage, power, and frequency requirements stated on the rear
panel. Do not attempt to defeat the safety ground connection.
