Three-channel Guitar Amplifiers
with
DSP & Channel Tracking
Congratulations!
You are now the proud owner of the Crate GLX65/120/212 three-channel guitar amplifier. This
rugged amplifier combines outstanding features with serious clean and distorted sounds. An easy to
operate DSP section lets you dial in a variety of digital effects including reverbs, delays, 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 automatically "tracks" the changes - your DSP
settings for each channel are stored and automatically recalled! The supplied three-button footswitch
allows you to select between the three channels and turn the DSP on and off by "remote control."
The top-mounted electronic tuner lets you get tuned and stay in tune any time the amplifier is on.
Like all Crate products, your GLX amplifier is designed by musicians, and built using only the best
components. Extensive testing confirms 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 read the information
contained in this manual before you begin playing.
And thank you for choosing

The Digital Signal Processor:
Crate's Digital Signal Processing offers 16 exciting digital effects, accessible through the DSP
Mode control. The effects are described below.

Channel Tracking:
Your Crate GLX amplifier gives you the power of Channel Tracking! Once you select a DSP set-
ting for each channel, Channel Tracking recalls those DSP settings automatically without chang-
ing the DSP controls! For example:
· Select the Clean channel. Set the DSP Mode to "8" (slow flange w/reverb)
· Select the Overdrive channel, Gain 1. Set the DSP Mode to "10" (slow chorus w/reverb)
(the setting for the Clean channel is now saved to memory)
· Select the Overdrive channel, Gain 2. Set the DSP Mode to "14" (touch 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 Touch
Wah, Channel Tracking automatically recalls the last setting for the Clean channel in this exam-
ple, Slow Flange with Reverb. Change to the Overdrive channel, Gain 1, and Slow Tremolo
Chorus w/Reverb is recalled. Change to the Overdrive channel, Gain 2, and Touch 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!)

1: MUTE: This switch, when depressed, silences the input signal. The Tuner (#21) remains active when this
switch is depressed.
2. 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 with serious overdrive.
3: GAIN: Use this control to adjust the amount of distortion for the Solo channel.
4: SHAPE: Use this control to "dial in" the tone for the Solo channel. Rotating the control counterclockwise
enhances the mid frequencies, while rotating the control clockwise enhances the low and high frequencies.
5: LEVEL: Use this control to adjust the output level of the Solo channel.
6: SOLO/RHYTHM SELECT: Use this switch to select the Solo or Rhythm channel. When this switch is
depressed, the Solo channel is selected. With the switch in the out position, the Rhythm channel is selected.
This switch is active only when the Solo-Rhythm/Clean Select switch (#12) is depressed.
7: GAIN: Use this control to adjust the amount of distortion for the Rhythm channel.
8: LOW: Use this control to adjust the low frequency level of the Rhythm channel.
9: MID: Use this control to adjust the midrange frequency level of the Rhythm channel.
10: HIGH: Use this control to adjust the high frequency level of the Rhythm channel.
11: LEVEL: Use this control to adjust the output level of the Rhythm channel.
12: SOLO-RHYTHM/CLEAN SELECT: Use this switch to select the Clean channel or the Solo and Rhythm
channels. With the switch in the out position, the Clean channel is selected. When the switch is depressed,
either the Solo or Rhythm channel is selected, depending on the setting of the Solo/Rhythm Select switch (#6).
CLEAN CHANNEL: A normal gain channel designed to give you crystal clean sounds.
13: VOL: Use this control to adjust the output level of the Clean channel.
14: LOW: Use this control to adjust the low frequency level of the Clean channel.
15: MID: Use this control to adjust the midrange frequency level of the Clean channel.
16: HIGH: Use this control to adjust the high frequency level of the Clean channel.
17: DSP LEVEL: Use this control to adjust the amount of digital effect: in its fully counterclockwise position the
signal will be "dry" (without any effect). As you rotate the control clockwise the amount of effect increases.
18: DSP MODE: Use this control to select one of the 16 built-in digital effects. A listing of the effects is shown
on page 3 of this manual.
19: LIGHTS: Use this switch to turn the front panel illumination on (top of the switch depressed) and offf (bot-
tom of the switch depressed).
20: POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch
depressed).

21. ELECTRONIC TUNER (top panel): The electronic tuner is active whenever the amplifier is turned on, pro-
viding constant, "real-time" tuning. The bottom row of LEDs indicate which note (string) is being tuned. The top
row of LEDs provides directional queues to facilitate quick and precise tuning of your instrument. The indicated
note (string) is properly tuned when only the center LED is illuminated.

The Rear Panel:
22: FUSE: The fuse protects the amplifier from damages caused by a faulty AC power source and/or
other problems. If the fuse opens, replace it ONLY with the same size and type. If fuses continue to
fail, check the AC source if the source is okay, contact your Crate dealer for service information.
23: AC LINE 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 stat-
ed on the rear panel. Do not attempt to defeat the safety ground connection.
24: CLEAN/SOLO/RHYTHM FOOTSWITCH JACK: Use this jack to connect the 1/4" stereo plug on
the footswitch cable to the three-button footswitch (supplied). This allows you to remotely switch
between the Clean and Distortion channels and between the Solo and the Rhythm channels.
25: DSP FOOTSWITCH JACK: Use this jack to connect the 1/4" mono plug on the footswitch cable
to the three-button footswitch (supplied). This allows you to remotely turn the DSP function on and off.
26. EXTENSION SPEAKER: Use this jack to connect the amplifier to an external speaker cabinet.
This jack is wired in series with the internal speaker(s) which remain active when an extension
speaker is connected.
27. EFFECTS RETURN: Use this jack to connect the signal from an external effects device to the amplifier.
28. EFFECTS SEND: Use this jack to connect the signal from the amplifier to an external effects
device for processing.
