The Electronic Tuner:
5
20. ELECTRONIC TUNER (top panel): The electronic tuner is active whenever the amplifier is turned on,
providing 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 facilitate 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):
21: AC LINE CORD: 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.
21: 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 fuses continue to fail,
check the AC source – if the source is okay, contact your Crate dealer for service information.
22: CHANNEL SELECT / GAIN FOOTSWITCH JACK: Use this jack to connect the stereo 1/4” plug of
the supplied three-button footswitch for remote control of channel selection and gain selection.
23: REVERB FOOTSWITCH JACK: Use this jack to connect the mono 1/4” plug of the supplied three-
button footswitch for remote control of DSP on and off.
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.
