XT65R Three Channel Guitar Amplifier

Congratulations!

You are now the proud owner of the Crate XT65R three-

channel guitar amplifier. This rugged amplifier combines out-

standing features with serious clean and distorted sounds.

Front panel RCA input jacks allow you to play along with your

favorite CD or tape. The rear panel Insert Jack allows you to

connect your effects for greater flexibility. Channel switching

and reverb may be controlled by means of a footswitch.

Like all Crate products, your XT 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 CCRRAATTEE.

XT65R Three Channel Guitar Amplifier

The Front Panel:

1: INPUT: Use this jack to connect your guitar to the amplifier by means of a shielded instrument cable.

SOLO/RHYTHM CHANNELS: High gain channels giving you sounds with serious overdrive.

2: SOLO LED: This LED illuminates when the Solo channel is selected.

3: GAIN: Use this control to adjust the amount of distortion produced by 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 (#13) is depressed.

7: RHYTHM LED: This LED illuminates when the Rhythm channel is selected.

8: GAIN: Use this control to adjust the amount of distortion produced by the Rhythm channel.

9: LOW: Use this control to adjust the low frequency level of the Solo/ Rhythm channel.

10: MID: Use this control to adjust the midrange frequency level of the Solo/ Rhythm channel.

11: HIGH: Use this control to adjust the high frequency level of the Solo/ Rhythm channel.

12: LEVEL: Use this control to adjust the output level of the Rhythm channel.

13: 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.

14: CLEAN LED: This LED illuminates when the Clean channel is selected.

15: LEVEL: Use this control to adjust the output level of the Clean channel.

16: LOW: Use this control to adjust the low frequency level of the Clean channel.

17: MID: Use this control to adjust the midrange frequency level of the Clean channel.

18: HIGH: Use this control to adjust the high frequency level of the Clean channel.

19: REVERB: Use this control to adjust the amount of reverb effect: in its fully counterclockwise position the

signal will be “dry” (without any effect). As you rotate the control clockwise the amount of reverb increases.

20: CD INPUT: Use these RCA jacks to connect the output from a CD player or tape deck to the amplifier. The

signal at these jacks is combined into a mono signal 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.

21: 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 power is on.

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: EXTENSION SPEAKER: Use this jack to connect the amplifier to an external speaker cabinet. This

jack is wired in series with the internal speaker which remains active when an extension speaker is con-

nected.

24: REVERB FOOTSWITCH: 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 reverb on and off.

25: CLEAN/SOLO/RHYTHM FOOTSWITCH: 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 Rhythm channels.

26: INSERT: Use this jack to connect an external

effects device to the amplifier. Use Crate’s STP201,

STP202, or STP203 stereo-to-mono Y-cord or an

adapter such as Crate’s YPP117 and two 1/4” mono

signal cables to connect to the effect as shown to the

immediate right.

27: AC LINE CORD (not shown): This grounded

power cord is to be plugged into a grounded power out-

let, wired to current electrical codes and compatible with

the voltage, power, and frequency requirements stated

on the rear panel. Do not attempt to defeat the safety

ground connection.
