18: POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch
depressed). The switch illuminates when the power is on.
19: ELECTRONIC TUNER (top panel): The electronic tuner is active whenever the amplifier is truned on, pro-
viding constant, “real time” tuning. The bottom row of LEDs indicate which note (string) is being tuned. The top
row of LEDs provides directional queues to faciltate quick and precise tuning of your instrument. The indicated
note (string) is properly tuned when only the center LED is illuminated.
The Rear Panel (not shown):
20: FUSE: The fuse protects the amplifier from damages 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 the fuse continues to
fail, check the AC source – if the source is okay, contact your Crate dealer for service information.
21: CHANNEL / GAIN SELECT 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 Overdrive channels and between Overdrive Gain 1 and Gain 2. When a footswitch is
used, the front panel Gain and Channel Select switches (#5, #9) are rendered ineffectual.
22: DSP 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 DSP on and off.
23: AC LINE CORD: This grounded power cord is to be plugged into a grounded power outlet, wired to cur-
rent 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.
Connecting to the Insert jack:
The Insert jack (#16) allows you to
patch an external effects device into
the amplifier prior to its power amp
stage. 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 the effect as
shown to the immediate right.
