16: INSERT: Use this jack to connect an exter-
nal effects device to the amplifier. Use a stereo
1/4” male Y-cord: ring = send, tip = return, sleeve
= ground. See the illustration to the right for
more information.
17: EXT. SPEAKER: Use this jack to connect an
extension speaker cabinet to the amplifier. This
jack is wired in series with the internal speaker.
18: FOOTSWITCH: Use this jack to connect a
two-button footswitch to the amplifier for remote
control of the Channel Select and Gain Select
settings.
19: POWER ON LED: This LED illuminates
when the amplifier is turned on.
20: POWER SWITCH: Use this switch to turn
the amplifier on (top of the switch depressed) an
off (bottom of the switch depressed).
21. POWER CORD (rear panel, not shown):
The grounded power cord should only be
plugged into a grounded power outlet that meets
all applicable electrical codes and is compatible
with the voltage, power and frequency require-
ments stated on the rear panel. Do not attempt
to defeat the safety ground connection!
22: FUSE (rear panel, not shown): The fuse
protects the amplifier against damages caused
by power overload conditions. If the fuse fails,
replace it only with the same size and type fuse.
If the fuse fails repeatedly check the AC source;
if it’s okay, contact your Crate dealer for service
information.
Connecting to the Insert jack:
The Insert jack (#16) lets you patch external
effects into the amplifier just 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 2 1/4” mono signal
cables to connect to the effect as shown below.
