16: INSERT: Connect an external effects device
via this jack. Use a stereo 1/4” male Y-cord: ring =
send, tip = return, sleeve = ground. See the illus-
tration on the panel to the right for more informa-
tion.
17: EXT. SPEAKER: Connect to an extension
speaker cabinet with this jack. The jack is wired in
series with the internal speaker(s).

turned on.
19: POWER SWITCH: Turns the amplifier ON in

20. POWER CORD (rear panel, not shown): Your
GFX-120/212 is equipped with a heavy-duty
grounded three-wire power cord. Be sure this cord
is properly plugged into a safely wired grounded
120 volt, 60Hz AC power outlet before use. (If your
GFX-120/212 was purchased outside the United
States, refer to the rear panel for power ratings.)
For your safety, never attempt to defeat the ground
connection on this cord.
21: FUSE (rear panel, not shown): Protects the
amplifier against damages caused from a faulty AC
power source or other problems. 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, contact your Crate dealer for service
information.
22: CHANNEL SELECT / GAIN FOOTSWITCH
JACK (rear panel, not shown): Connect the
stereo 1/4” plug of the supplied three-button
footswitch here for remote control of the Channel
Select and Gain Select settings.
23: DSP FOOTSWITCH JACK (rear panel, not
shown): Connect the mono 1/4” plug of the sup-
plied three-button footswitch here for remote con-
trol of the DSP on and off.
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.
