Congratulations and thank you for choosing the Crate GTX30
Guitar Amplifier with Digital Signal Processing. This rugged amplifi-
er features a Clean channel with a three-band EQ and level control,
and a Solo channel with our patented FlexWave technology, Gain,
Level and Shape control. An easy to operate DSP section lets you
dial in a variety of digital effects including reverbs, delays, octave
and wah-wahs. RCA input jacks allow connection of a CD or tape
player for practicing with your favorite music, while the Headphones
jack allows you to practice in private.

1: INPUT: Use this 1/4" jack to connect your guitar to
the amplifier by means of a shielded instrument cable.
SOLO CHANNEL: A high gain channel giving you
sounds from a slight edge to serious overdrive.
2: GAIN: Use this control to adjust the amount of dis-
tortion for the Solo channel.
3: SHAPE: Use this control to adjust the tone of the
Solo channel.
4: LEVEL: Use this control to adjust the output level
of the Solo channel.
5: SOLO/CLEAN: Use this switch to select the Solo
or Clean channel. With the switch in the out position,
the Clean channel is selected. When the switch is
depressed, the Solo channel is selected.
CLEAN CHANNEL: A normal gain channel designed
to give you crystal clear sounds to medium distortion.
6: LEVEL: Use this control to adjust the output level
of the Clean channel.
7: LOW: Use this control to adjust the low frequency
level of the clean channel.
8: MID: Use this control to adjust the midrange fre-
quency level of the clean channel.
9: HIGH: Use this control to adjust the high frequen-
cy level of the clean channel.
10: DSP LEVEL: Use this control to adjust the level of
the selected digital effect. The DSP effects can be
turned on and off by using a footswitch (#16, rear
panel).
11: DSP MODE: Use this control to select one of the
16 built-in digital effects. The numbers around the
control correspond to the digital effects as listed in the
chart below.
12: CD INPUT: Use these RCA jacks to connect the
output from a CD payer or tape deck to the amplifier.
The signal at these jacks is summed into a mono sig-
nal which is sent to the internal power amp circuit.
Use the CD or tape player's output level control to
adjust the signal for the proper mix with your guitar.
13: HEADPHONES: Use this jack to connect head-
phones to the amplifier. The internal speaker is dis-
connected when headphones are used.
CAUTION: To avoid possible damage to your
hearing, do not use headphones for extended
periods of time at extremely loud levels.
14: POWER: Use this switch to turn the amplifier on
(top of the switch depressed) and off (bottom of the
switch depressed). The switch illuminates when the
amplifier is turned on.
15: EXTENSION SPEAKER (rear panel, not shown):
Use this jack to connect the amplifier to an external
speaker. The internal speaker is disconnected when this
jack is used. The impedance of the external speaker
must be 4 ohms or greater.
WARNING: Do not attempt to use headphones in
the Speaker jack! Permanent hearing damage
could result!
16: FOOTSWITCH (rear panel, not shown): Use this
jack to connect the 1/4" stereo plug on the cable of a
two-button footswitch (such as the Crate CFP2). This
allows you to remotely switch between the Clean and
Solo channels and turn the DSP function on and off.
17: POWER CORD (rear panel, not shown): The
grounded power cord should only be plugged into a
grounded power outlet that meets all applicable electri-
cal codes and is compatible with the voltage, power, and
frequency requirements stated on the rear panel. Do not
attempt to defeat the safety ground connection.
