GLX1200H

Three-channel Guitar Amplifier

with

DSP & Channel Tracking

Congratulations!

You are now the proud owner of the Crate GLX1200H three-channel guitar amplifier. This rugged
amp head 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 electronic
tuner on the front panel 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 T

racking:

Your Crate GLX1200H amplifier gives you the power of Channel Tracking! Once you select a
DSP setting for each channel, Channel Tracking recalls those DSP settings automatically – with­out changing the DSP controls! For example:

• Select the Clean channel. Set the DSP Mode to “8”

(slow deep flange w/reverb)

• Select the Overdrive channel, Gain 1. Set the DSP Mode to “10” (slow tremolo 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 exam­ple, 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 T racking still retains the settings – until you change them!)
