interference in a residential installation. This equipment generates, uses and can radiate radio frequen-
cy energy and, if not installed and used in accordance with the instructions, may cause harmful interfer-
ence to radio communications. However, there is no guarantee that interference will not occur in a par-
ticular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

VTX200SH Three-Channel Guitar Amp Head with Stereo DSP
Congratulations!
You are now the proud owner of the Crate VTX200SH three-channel guitar amp
head with Stereo Digital Signal Processing (DSP). This rugged amplifier combines out-
standing features with serious clean and distorted sounds. Dual DSP controls provide
15 “Must Have” effects and 15 Delay effects which can be combined for a wide variety
of sounds. The Tap/Save button allows you to manually set the tempo of many of the
effects and to save new DSP presets in the amplifier’s non-volatile memory. A sepa-
rate Reverb control adds even more to the array of effects. Channel switching and
DSP may be controlled by means of a footswitch, which also allows access to two DSP
presets on each of the three channels. Stereo and Mono Effects Loops allow you to
connect additional effects for even greater flexibility. The electronic tuner (with a Mute
switch for silent tuning) lets you get tuned and stay in tune any time the amplifier is on.
Like all Crate products, your VTX200SH 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 suggest that you read
the information contained in this guide before you begin playing.
CRATE
And thank you for choosing
.

1: 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.
2: REVERB: Use this control to adjust the amount of the digital reverb effect. In its fully counter clock-
wise position the signal is “dry” (without any reverb). As you rotate the control clockwise the amount
of reverb increases. The Reverb setting may be saved as a channel preset - see page 8.
3: Tap/Save LED: This LED flashes in time with the tempo set by the Tap/Save button (#4) and
serves as a status indicator for certain DSP activities (see page 8).
4: Tap/Save: Use this pushbutton to set the tempo of many of the effects by tapping the button
repeatedly in time with the desired tempo. The Tap/Save button is also used to save DSP presets
and to restore the factory default DSP settings. Additional information about the Tap/Save button is
on pages 7 and 8.
5. DELAY: Use this control to select one of the fifteen digital delay effects. Complete information
about the DSP effects is on page 7.
6. EFFECTS: Use this control to select one of the fifteen digital effects. Complete information about
the DSP effects is on page 7.
7: TUNER: The electronic tuner is active whenever the amplifier is turned on, providing 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 facilitate quick and precise tuning of your instrument. The
indicated note (string) is properly tuned when only the center LED is illuminated.
8: MUTE: This switch, when depressed, mutes the output signal at the speaker jacks and the effects
loops, allowing you to silently tune or switch instruments. The adjacent LED illuminates when the
Mute function is active.
CHANNEL 3 - Featuring a high gain FlexWave circuit for extreme distortion and sustain:
9: CHANNEL 3 SELECT: This switch, when depressed, selects Channel 3 as the active channel. The
adjacent LED illuminates when Channel 3 is active.
10: HIGH: Use this control to adjust the high frequency level of Channel 3.
11: LEVEL: Use this control to adjust the output level of Channel 3.
12: MID: Use this control to adjust the midrange frequency level of Channel 3.
13: GAIN: Use this control to adjust the amount of distortion produced by Channel 3.
14: LOW: Use this control to adjust the low frequency level of Channel 3.

28: FOOTSWITCH: Use this jack to connect the footswitch cable (5-conductor midi cable) to the four-button
footswitch (supplied). This allows you to remotely switch between the channels, set tap tempos, save new presets,
and access a second set of DSP presets. (See page 9 for additional information.)
29: MONO EFFECTS LOOP SEND: When using a mono external effects processor, connect this jack to the input
jack of the effect by means of a shielded signal cable.
30: MONO EFFECTS LOOP RETURN: When using a mono external effects processor, connect this jack to the
output jack of the effect by means of a shielded signal cable.
31: STEREO EFFECTS LOOP SEND: When using a stereo external effects processor, connect this jack to the
input jack of the effect by means of a shielded three conductor signal cable terminated with a stereo (R/T/S) 1/4”
connector.
32: STEREO EFFECTS LOOP RETURN: When using a stereo external effects processor, connect this jack to the
output jack of the effect by means of a shielded three conductor signal cable terminated with a stereo (R/T/S) 1/4”
connector.
33: SPEAKER OUTPUTS: Use these jacks to connect the amplifier to your speaker(s) by means of speaker cables
with mono 1/4” plugs. The VTX200SH has two separate internal power amplifiers: one for the left channel, one for the
right. The two Left Speaker Output jacks are wired in parallel to each other, as are the two Right Speaker Output jacks.
Make certain the total impedance of your speakers does not go below four ohms per channel. Use the chart below to
help determine parallel loads. If in doubt, ask your dealer.

When using the stereo Chorus effect the right channel is dry and the left channel is detuned (wet). Each channel
will provide 70 watts RMS into an eight ohm load and 100 watts RMS into a four ohm load.
34: AC LINE 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. Do
not attempt to defeat the safety ground connection.
WARNING: The speaker output of this unit can exceed 10 Watts and could be a
shock injury. Connection to speakers should be performed by a skilled person in
compliance with local building codes. Class 2 wiring is required for speaker cables.
Use of external speakers outside the ratings stated at the speaker jack may result
in a shock injury or damage to the unit.
