OWNER’S
MANUAL
GFX2200HT
GUITAR AMPLIFIER
with Channel Tracking &
Digital Signal Processing
Congratulations!
You are now the proud owner of the Crate GFX2200HT guitar amplifier. This rugged amplifier combines
outstanding features with serious clean and distorted sounds, with lots of power. An easy to operate DSP
(Digital Signal Processing) section lets you dial in a variety of digital effects including reverbs, octave and
wah-wahs – with a separate level control. Crate’s unique Channel Tracking feature means that as you
switch between channels and gains, the DSP “tracks” the changes – your DSPsettings for each channel are
stored and automatically recalled! The supplied three-button footswitch allows you to select channels,
change the overdrive gain, and turn the DSP on and off by “remote control.” The front-mounted electronic
tuner allows you to tune your instrument any time the amplifier is on.
Like all Crate products, your GFX2200HT is designed by musicians and assembled using only the best
components. Extensive testing confirms that this amplifier is the absolute best it can be. Crate’s transferable
five-year warranty protects your investment long after many other companies’ warranties have expired.
In order to get the most out of your new amplifier, we strongly urge you to read the information contained
in this manual before yo begin playing.
Thank you
for choosing

The Digital Signal Processor:
Crate’s Digital Signal Processing (DSP) offers 16 exciting digital effects, accessible through the DSP
Mode control. The effects are described as follows:
1 REV 1 small room reverb
2 REV 2 medium room reverb
3 REV 3 large room reverb
4 REV 4 concert hall reverb
5 DLY 1 short slapback + small room reverb
6 DLY 2 medium delay + plate reverb
7 DLY 3 long delay + large room reverb
8 FLNG 1 slow deep flange + reverb
9 FLNG 2 flange + reverb + delay
10 CHO 1 slow tremolo chorus + reverb
11 CHO 2 chorus + reverb + delay
12 RTRY simulated rotating speaker effect
13 OCTV DN adds a signal one octave lower than input
14 T-WAH touch sensitive wah-wah effect
15 I-WAH inverse wah-wah effect
16 DBLR simulated second track, slightly out-of-sync
Channel Tracking:
Your Crate GFX2200HT gives you the power of Channel Tracking! Once you select a DSP setting for
each channel, Channel Tracking recalls those DSPsettings automatically – without changing the DSP controls!
For example:
• Select the Clean channel. Set the DSP Mode to “FLNG 1”
(slow flange + reverb)
• Select the Overdrive channel, Gain 1. Set the DSP Mode to “CHO 1” (slow chorus + reverb) (the setting for
the Clean channel is now saved to memory)
• Select the Overdrive channel, Gain 2. Set the DSP Mode to “T-WAH”
(touch wah-wah) (the setting for the
Overdrive channel, Gain 1 is now saved to memory)
• Reselect the Clean channel (the setting for the Overdrive channel, Gain 2 is now saved to memory)
Now when you go back to the Clean channel, even though the DSP Mode was last set to “T-WAH,” Channel
Tracking automatically recalls the last setting for the Clean channel – in this example, “FLNG 1.” Change to the
Overdrive channel, Gain 1, and “CHO 1” is recalled. Change to the Overdrive channel, Gain 2, and “T-WAH” is
recalled. That’s the power of Channel Tracking!
(Note: Even when the power is turned off, Channel Tracking still retains the settings – until you change them!)

. POWER: Use this switch to turn the amplier on (top of the switch depressed) and off
bottom of the switch depressed).
. ON LED: This LED illuminates when the
mplifier is turned on.
. CHANNEL SELECT FOOTSWITCH: In-
ert the 1/4” stereo plug on the cable attached
o the two-button footswitch (supplied) into
his jack. This will allow you to use the
ootswitch to control channel and gain selec-
on (Channel A- see #18).
. DSP FOOTSWITCH: Insert the 1/4” mono
lug on the cable attached to the two-button
ootswitch (supplied) into this jack. This will
llow you to use the footswitch for on/off conrol of the selected DSP effect.
. DSP MODE: Use this control to select one
f the 16 built-in digital effects. A listing of the
ffects is shown on page 3.
. DSP LEVEL: Use this control to adjust the
mount of the digital effect. In its fully counter
lockwise position the signal will be “dry”
without any effect). As you rotate the control
lockwise the amount of effect increases.
CHANNEL B: The Clean Channel:
. BRIGHT: This switch, when depressed,
oosts the upper frequencies of Channel B.
. LEVEL: Use this control to adjust the out-
ut level of Channel B.
. HIGH: Use this control to adjust the high
requency level of Channel B.
10. MID: Use this control to adjust the
midrange frequency level of Channel B.
11. LOW: Use this control to adjust the low
frequency level of Channel B.
12. CHANNEL SELECT: Use this switch to
select either channel. With the switch in the
out position, Channel B is selected and the
adjacent LED illuminates. When the switch is
depressed, Channel Ais selected.
CHANNEL A: The Overdrive Channel:
13. LEVEL: Use this control to adjust the output level of Channel A.
14. HIGH: Use this control to adjust the high
frequency level of Channel A.
15. MID: Use this control to adjust the
midrange frequency level of Channel A.
16. LOW: Use this control to adjust the low
frequency level of Channel A.
17. GAIN TWO: Use this control to adjust the
amount of heavy distortion for Channel A.
Gain Two produces more intense distortion
than Gain One (#19) and is active when the
Gain switch (#18) is depressed.
18. GAIN SELECT: Use this switch to select
one of the two gain controls for Channel A
(#17, #19). When the switch is depressed,
gain two is selected and gain one is disabled.
Both of the adjacent LEDs will illuminate. With
the switch in the out position, gain one is
selected. The right-side LED will illuminate.
When a footswitch (#3) is used, this switch is
disabled. The LEDs continue to function in the
manner described.
19. GAIN ONE: Use this control to adjust the
amount of light distortion for Channel A. Gain
One produces less intense distortion than
Gain Two (#17) and is active when the Gain
switch (#18) is in the out position.
20. INPUT: Use this 1/4” jack to connect your
guitar to the amplifier by means of a shielded
instrument cable.
21. TUNER: The tuner is active whenever the
amplifier is turned on. The bottom row of
LEDs correspond to the strings of your guitar.
The top row of LEDs indicate which way you
need to adjust each string for proper tuning. A
string is properly tuned whenever the corresponding LED on the bottom row and the LED
in the center of the top row are illuminated.

22. EFFECTS LOOP LINE OUT: When
using an external effects processor, connect this jack to the input of the effect by
means of a shielded signal cable. This jack
also doubles as a source for a post-EQ,
preamp signal to send your signal to a mixing board, recorder, powered monitor or
external amplifier.
23. EFFECTS LOOP LINE IN: When
using an external effects processor, connect this jack to the output of the effect by
means of a shielded signal cable. This jack
also doubles as a direct connection to the
power amp, bypassing the input and preamp stages. This is useful for “slaving” a
pair of amplifiers together.
24. SPEAKERS: Use these jacks to connect the amplifier to your speaker cabinet(s) using speaker cables with mono 1/4”
plugs. These jacks are wired in parallel.
Make sure that the combined impedance of
your speakers is equal to or greater than 2
ohms! Use the chart below to help determine parallel loads. If in doubt, ask your
dealer.
CAB IMP # CABS TOTAL IMP
4 ohms 2 2 ohms
8 ohms 2 4 ohms
8 ohms 4 2 ohms
16 ohms 2 8 ohms
16 ohms 4 4 ohms
16 ohms 8 2 ohms
25. POWER CORD: This grounded power
cord is to be plugged into a grounded
power outlet, wired to current electrical
codes and compatible with the voltage,
power, and frequency requirements stated
on the rear panel. Don not attempt to
defeat the safety ground connection.
