The Rear Panel:

22:INSERT: Use this jack to connect an external effects device to the amplifier. Use Crate’s STP201, STP202, or STP203 stereo-to-mono Y-cord or an adapter such as Crate’s YPP117 and two 1/4” mono signal cables to connect to the effect as shown below.

23:CLEAN/SOLO/RHYTHM 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.

24: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.

25:SPEAKER: Use this jack to connect the amplifier to your speaker cabinet(s). The minimum impedance for the cabinet(s) is 4 ohms.

WARNING: The speaker output of this unit can exceed 10 Watts and could be a shock injury. Connection to speakers should be performed by a skilled person in compliance with local building codes. Class 2 wiring is required for speaker cables. Use of external speakers outside the ratings stated at the speaker jack may result in a shock injury or damage to the unit.

26:FUSE: The fuse protects the amplifier from dam- ages caused by a faulty AC power source and/or other problems. If the fuse opens, 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.

27: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 con- nection.
