FXT65Guitar Amp with DSP & Channel Tracking
The Digital Signal Processor:
The FXT65’s Digital Signal Processor provides 16 exciting digital effects. Use the DSP Selector control
to choose the desired effect, then use the DSP Level control to mix in the desired amount of effect.
The effects are described below:
FLNG 1
FLNG 2
CHO 1
slow deep flange + reverb
flange + reverb + delay
slow tremolo chorus + reverb
chorus + reverb + delay
CHO 2
RTRY
OCTV DOWN
T-WAH
simulated rotary speaker effect
adds a signal one octave lower than input
touch sensitive wah-wah effect
inverse wah-wah effect
I-WAH
DOUBLER
REV (1)
REV (2)
REV (3)
REV (4)
DLY (1)
DLY (2)
DLY (3)
simulated second track, slightly out of sync
small room reverb
medium room reverb
large room reverb
concert hall reverb
short slapback + small room reverb
medium delay + plate reverb
long delay + large room reverb
Channel Tracking:
The FXT65 gives you the power of Channel Tracking! Once you select a DSP setting for each chan-
nel, Channel Tracking recalls those DSP setting automatically – without changing the DSP controls!
For example:
• Select the Clean channel. Set the DSP Selector to “FLNG 1” (slow flange + reverb)
• Select the Overdrive channel, Gain 1. Set the DSP Selector 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 Selector 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 Selector 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 chan-
nel, 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!)

1: INPUT: Use this jack to connect your guitar to the amplifier by means of a shielded instrument cable.
OVERDRIVE CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive.
2: GAIN 1: Use this control to adjust the amount of light distortion for the Overdrive channel. Gain 1 produces less
intense distortion than Gain 2 (#3) and is active when the Gain Select switch (#5) is in the out position.
3: GAIN 2: Use this control to adjust the amount of heavy distortion for the Overdrive channel. Gain 2 produces
more intense distortion than Gain 1 (#2) and is active when the Gain switch (#5) is depressed.
4: SHAPE: Use this control to “dial in” the tone for the Overdrive channel when Gain 2 is selected. Rotating the
control counterclockwise enhances the mid frequencies, while rotating the control clockwise enhances the low and
high frequencies. This control is only active when Gain 2 is selected.
5: GAIN SELECT: Use this switch to select which Gain control is active for the Overdrive channel. With the switch
in the out position, Gain 1 is selected. When the switch is depressed, Gain 2 is selected. When a footswitch is
connected to the Channel / Gain Select Footswitch jack (#21), this switch is rendered inactive and the Gain Select
function is controlled by the footswitch (see #21).
6: LOW: Use this control to adjust the low frequency level of the Overdrive channel.
7: HIGH: Use this control to adjust the high frequency level of the Overdrive channel.
8: LEVEL: Use this control to adjust the output level of the Overdrive channel.
9: CHANNEL SELECT: Use this switch to select either channel. With the switch in the out position, the Clean
channel is selected. When the switch is depressed, the Overdrive channel is selected. The adjacent LEDs illumi-
nate to indicate which channel is active. When a footswitch is connected to the Channel / Gain Select Footswitch
jack (#21), this switch is inactive and the Channel Select function is controlled by the footswitch (see #21).
CLEAN CHANNEL: A normal gain channel designed to give you crystal clear sounds to medium distortion.
10: VOL: Use this control to adjust the output level of the Clean channel.
11: LOW: Use this control to adjust the low frequency level of the Clean channel.
12: MID: Use this control to adjust the midrange frequency level of the Clean channel.
13: HIGH: Use this control to adjust the high frequency level of the Clean channel.
14: DSP LEVEL: Use this control to adjust the amount of digital effect: in its fully counter clockwise position the
signal will be “dry” (without any effect). As you rotate the control clockwise the amount of effect increases.
15: DSP SELECTOR: 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 user’s guide.
16: INSERT: Use this jack to connect an external effects device to the amplifier. Use a stereo 1/4” male Y con-
nector: ring = send, tip = return, sleeve = ground. (Refer to the illustration at the bottom of page 5.)
17. EXTERNAL SPEAKER: Use this jack to connect the amplifier to an external speaker. This jack is wired in
series with the internal speaker, which remains active even when an external speaker is connected.

18: 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.
19: ELECTRONIC TUNER (top panel): The electronic tuner is active whenever the amplifier is truned 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 faciltate quick and precise tuning of your instrument. The indicated
note (string) is properly tuned when only the center LED is illuminated.
The Rear Panel (not shown):
20: 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 the fuse continues to
fail, check the AC source – if the source is okay, contact your Crate dealer for service information.
21: CHANNEL / GAIN SELECT 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 Overdrive channels and between Overdrive Gain 1 and Gain 2. When a footswitch is
used, the front panel Gain and Channel Select switches (#5, #9) are rendered ineffectual.
22: DSP 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 DSP on and off.
23: AC LINE CORD: This grounded power cord is to be plugged into a grounded power outlet, wired to cur-
rent 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.

The Insert jack (#16) allows you to
patch an external effects device into
the amplifier prior to its power amp
stage. 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 the effect as
shown to the immediate right.
