Crate Amplifiers GX-120, GX-212+ User Manual
GX-120/212+
Guitar Amplifier
Congratulations!
You are now the proud owner of the Crate GX-120/212+ guitar amplifier. Each of
these rugged amplifiers delivers serious clean and distorted sounds through premium 12”
Crate Custom speakers (one in the GX-120, two in the GX-212+). Channel selection and
Crate’s Exclusive Shape circuit are controllable by use of a two-button footswitch. An
Insert jack allows virtually noise-free connection of your favorite effects.
Like all Crate products, your GX-120/212+ is Musician Made in the U.S.A., using only
the best components. Extensive testing at the hands (and ears) of skilled technicians and
musicians insures you that this amplifier is the absolute best it can be.
In order to get the most out of your new amplifier, we strongly urge you to go over
the information contained in this manual before you begin playing.
And thank you
for choosing

ENGLISH
FRONT PANEL - INPUT SECTION
1: Input jack accepts a standard 1/4” phone plug and is suit-
able for any low to line level input source.
LEAD CHANNEL CONTROLS
2: Gain is used to set the level of distortion. The signal gain
setting will be boosted when the Shape active button (#4) is
pressed in.
3: Shape adjusts the general tone. Counter-clockwise emphasizes midrange frequencies and clockwise emphasizes low and
high frequencies. The Shape control is only active when the
Shape Active button (#4) is pressed in.
4: Shape Active boosts the gain of the Lead channel and activates the Shape control (#3).
5: Low adjusts the amount of low frequency tone.
6: High adjusts the amount of high frequency tone or “presence”.
7: Level controls the overall volume and should be used in
conjunction with the Gain control (#2).
CHANNEL SWITCHING CONTROL
8: Lead Channel Indicator LED will be lit when the amplifier is
in the Lead Channel mode.
9: Channel Select Switch is used to select either the Lead or
Rhythm Channel. This switch is defeated if an external
footswitch is used.
10: Rhythm Channel Indicator LED will be lit when the amplifier is in the Rhythm Channel mode.
RHYTHM CHANNEL CONTROLS
11: Volume sets the overall listening level of the Rhythm
Channel. This control is independent of any setting made in
Channel A.
12: Low adjusts the amount of low frequency tone.
13: Mid adjusts the amount of midrange frequency tone.
14: High adjusts the amount of high frequency tone.
15: Bright Switch gives a brighter tone.
REVERB CONTROLS
16: Lead sets the amount of reverb for the Lead Channel.
17: Rhythm sets the amount of reverb for the Rhythm Channel.
18: Insert/Effects Loop jack allows connection of external
effects. Use a stereo 1/4” male Y cord here: ring = send, tip =
return and sleeve is ground for both. See the illustration below
for more information.
19: Ext. Speaker jack allows connection to an extension speaker cabinet. This jack is in series with the internal speaker(s).
20: Footswitch jack allows the use of an optional dual
footswitch for remote control of the Channel Select and Shape
Active buttons.
21: Power Indicator LED will be lit when the unit is turned on.
22: Power Switch turns the AC power on and off.
REAR PANEL
23: Power Cord: Your GX-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 GX-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.
24: Fuse 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 2.5A 250V normal
blow fuse. If the fuse blows repeatedly check the AC source; if
it’s okay, contact your Crate dealer for service information.
Connecting to the Insert jack:
The Insert/Effects Loop jack (#18) lets you patch external
effects into the amplifier just prior to its power amp stage. Use
Crate’s CYC6MS stereo-to-mono Y-cord or an adapter such as
Crate’s CA11Y and 2 1/4” mono signal cables to connect to the
effect as shown below.
