GFX-120/212

GUITAR AMPLIFIER WITH

DIGITAL SIGNAL PROCESSING

OWNER’S MANUAL

Congratulations!

You are now the proud owner of the Crate GFX-120/212 guitar amplifier. These

rugged amplifiers combine outstanding features with serious clean and distorted

sounds. An easy to operate DSP section lets you dial in a variety of digital effects such

as delay, flange, chorus and reverb – with separate level control. Channel selection,

Crate’s exclusive Shape circuit, and DSP on/off are controllable by the supplied three-

button footswitch. An insert jack allows virtually noise-free connection of your favorite

effects.

Like all Crate products, your GFX-120/212 is Musician Made in the U.S.A., using

only the best components. Extensive testing at the hands (and ears) of skilled techni-

cians 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

1: INPUT: Connect your guitar here using a shield-

ed instrument cable.

no output; turning the control to the right increases

the output. Use this control along with the Gain and

Shape controls (#2, 3 & 4) to create a wide variety

of sounds.

OVERDRIVE CHANNEL: A high gain channel giv-

ing you sounds from a slight edge to serious over-

drive.

9: CHANNEL SELECT: When this switch is

pressed in the Overdrive Channel is engaged. The

Clean Channel is selected when this switch is out.

A footswitch (#22) overrides this switch. The adja-

cent LEDs indicate which channel is selected.

2: GAIN 1: When active, sets the amount of com-

pression and distortion from the amplifier. At far

left, the sound will have a thick compressed quali-

ty. As you turn the control to the right the amount of

distortion increases. Gain 1 produces less intense

distortion than Gain 2 and is active only when the

Gain Select switch (#5) is out.

CLEAN CHANNEL: A normal gain channel

designed to give you crystal clear sounds.

10: LEVEL: Sets the output volume level from the

Clean Channel: in the far-left position there is no

output; turning the control to the right increases the

output level.

3: GAIN 2: When active, sets the amount of com-

pression and distortion from the amplifier. At far

left, the sound will have a thick compressed quali-

ty. As you turn the control to the right the amount of

distortion increases. Gain 2 produces more intense

distortion than Gain 1 and is active only when the

Gain Select switch (#5) is in.

11: LOW: Adjusts the low frequency output level:

to the left reduces the low frequency output; to the

right increases it. This control allows a range of

22dB at 80Hz.

4: SHAPE: Working in conjunction with the Gain 2

control, rotate the Shape control until you find the

sound you’re looking for. Turning the control

towards the left enhances the mid frequencies;

turning it to the right enhances the low and high fre-

quencies. (Only affects Gain 2 when active.)

12: MID: Adjusts the mid frequency output level: to

the left reduces the midrange output; turning it to

the right increases it. This control allows a range of

14dB at 600Hz.

13: HIGH: Adjusts the high frequency output level:

to the left reduces the high frequency output; to the

right increases it. This control allows a range of

28dB at 10kHz.

5: GAIN SELECT: Switches between Gain 1 (out)

and Gain 2 (in). A footswitch (#22) overrides this

switch.

14: DSP LEVEL: Adjust the amount of digital sig-

nal processing with this control: in the full-left posi-

tion the output signal is “dry” (no effect); rotating

the control to the right increases the amount of

effect. The DSP can be turned on and off with a

footswitch (#23).

6: LOW: Adjusts the low frequency output level: to

the left reduces the low frequency output; to the

right increases it. This control allows a range of

11dB at 80Hz.

7: HIGH: Adjusts the high frequency output level:

to the left reduces the high frequency output, to the

right increases it. This control allows a range of

10dB at 10kHz.

15: DSP MODE: Select the type of digital effect(s)

desired with this control. Each category and its

central location is called out (delay, flange, etc.) by

the markings around the control; there are two

variations per effect, as follows:

8: LEVEL: Sets the output volume level from the

Overdrive Channel: in the far-left position there is

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.

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.
