GX-212 Amplifier
16: EXT. SPEAKER: Use this jack to connect an
extension speaker cabinet to the amplifier. This
jack is wired in series with the internal speaker(s).
WARNING: Do not attempt to use head-
phones in the Speaker jack! Permanent
hearing damage could result!
17: POWER ON LED: This LED illuminates
when the amplifier is turned on.
18: POWER SWITCH: Use this switch to turn
the amplifier on (top of the switch depressed)
and off (bottom of the switch depressed).
19. 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.
20: FUSE (rear panel, not shown): This pro-
tects the amplifier against damages caused
from a faulty AC power source or other prob-
lems. If the fuse blows, replace it ONLY with the
same size and type fuse. If the fuse blows
repeatedly check the AC source; if it’s okay, con-
tact your Crate dealer for service information.
21: CHANNEL SELECT / GAIN FOOTSWITCH
JACK (rear panel, not shown):
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
Gain 1 and 2 of the Overdrive channel.
22: REVERB FOOTSWITCH JACK (rear panel,
not shown):
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.

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 in the
