Guitar Amplifier

the high frequency output. Rotating the control
clockwise increases the high frequency out-
put. The High control provides a range of 28dB
of boost or cut at 10kHz.
14: DSP LEVEL: Use this control to adjust the
amount of digital signal processing to be
applied to the signal. In the fully counterclock-
wise position the output signal is “dry” (no
effect applied). As you rotate the control clock-
wise the amount of effect increases. The DSP
may be turned on and off with a footswitch
(#17).
15: DSP MODE: Use this control to select one
of the ten digital effects. The nomenclature
around the Mode control defines the five types
of effects available. Each effect listed has two
variations as described below:
DELAY: Slapback delay
Long delay w/regeneration
FLANGE: Light Flange
Heavy Flange
CHORUS: Slow Chorus
Fast Chorus
CHO-REV: Chorus w/small room reverb
Chorus w/large room reverb
REVERB: Small room reverb
Large room reverb
16: INSERT: Use this jack to connect an
external signal processor to the amplifier.
Refer to the adjacent illustration for additional
information.
17: FOOTSWITCH: Use this jack to connect a
two-button footswitch to the amplifier for
remote control of channel selection and DSP
on and off.
18: ON LED: This LED illuminates when the
amplifier is turned on.
19: POWER: Use this switch to turn the ampli-
fier on (top of the switch depressed) and off
(bottom of the switch depressed).
20: POWER CORD (rear panel, not shown):
The grounded power cord should only be
plugged into a grounded power outlet that
meets all applicable electrical codes and is
compatible with the voltage, power, and fre-
quency requirements stated on the rear panel.
Do not attempt to defeat the safety ground
connection.
Connecting to the Insert jack:
The Insert jack (#16) allow 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 below.
