MANUAL

GFX2200HT GUITAR AMPLIFIER

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 DSP settings 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

LEVEL

Use the DSP Mode control to access any of the 16 built-in digital effects.

Use the level control to mix in the desired amount of each effect.

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 DSP settings 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: Inert 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 selecon (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 outut 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 A is 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.

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.
