Crate Amplifiers GX-1200H User Manual

OWNER’S MANUAL

Congratulations!

You are now the proud owner of the Crate GX-1200H guitar amplifier. This rugged
amp head combines outstanding features with serious clean and distorted sounds.
Channel selection, Crate’s exclusive Shape circuit, and reverb 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 GX-1200H 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

GX-1200H

GUITAR AMPLIFIER

1: INPUT: Connect your guitar here using a
shielded instrument cable.

OVERDRIVE CHANNEL: A high gain channel
giving you sounds from a slight edge to serious
overdrive.

2: GAIN 1: When active, sets the amount of
compression and distortion from the amplifier. At
far left, the sound will have a thick compressed
quality. 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.

3: GAIN 2: When active, sets the amount of
compression and distortion from the amplifier. At
far left, the sound will have a thick compressed
quality. 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.

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
frequencies. (Only affects Gain 2 when active.)

5: GAIN SELECT: Switches between Gain 1
(out) and Gain 2 (in). A footswitch (#21) over­rides this switch.

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.

8: LEVEL: Sets the output volume level from the
Overdrive Channel: in the far-left position there
is 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.

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 (#21) overrides this switch.
The adjacent LEDs indicate which channel is
selected.

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.

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.

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.

14: REVERB LEVEL: Adjust the amount of
reverberation with this control: in the full-left
position the output signal is “dry” (no reverb);
rotating the control to the right increases the
amount of reverb. Reverb can be turned on and
off with a footswitch (#22).
