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.
