24.FUSE: The fuse protects the amplifier from damage caused by a faulty AC power source or other problems. If the fuse opens, replace it with the same size and type. If fuses continue to fail, check the AC source. If the source is okay, refer to page 12 or con- tact your Crate dealer for service information.

25.EXTENSION SPEAKER: Use this jack to connect the amplifier to an external speak- er cabinet. This jack is wired in series with the internal speaker, which remains active when an extension speaker is connected.

26.DSP FOOTSWITCH:

Use this jack to connect one of the footswitch cables to the three-button footswitch (sup- plied). This allows you to select between two DSP presets for each of the three channels. Additional information about the operation

of the footswitch is on page 8.

28.INSERT: Use this jack to connect an external signal processor 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.

29.POWER 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!

30.ELECTRONIC TUNER (cabinet top) The electronic tuner is active whenever the amplifier is turned on, providing constant

“real-time” tuning. The row of red LEDs on the left indicates which note is being tuned.

When a single LED is lit, it represents the note

27.CHANNEL FOOTSWITCH: Use this jack to connect one of the footswitch cables to the three-button foot- switch (supplied). This allows you to remotely switch between the Clean, High Gain, and Overdrive channels. Additional information about the operation of the footswitch is on page 8.

that appears just below the LED. When two LEDs are lit, it represents the note that appears between them in the bottom row. The left green LED indicates the note is flat, and the right green LED indicates the note is sharp. The note is properly tuned when both LEDs are lit at the same time.
