Important Safeguards and Precautions:
All Crate products are designed for continuous safe operation. Abiding by the following
rules can help prevent damage to your amplifier, yourself and others.
• The amplifier is equipped with a three-pronged AC power cord. To
reduce the risk of electrical shock, NEVER remove or otherwise attempt
to defeat the ground pin of the power cord.
• Connect the amplifier ONLY to a properly grounded AC outlet of the
proper voltage for your amp.
• Avoid sudden temperature extremes, rain and moisture. Also, avoid
sudden and intense impact. (If the unit has been subjected to any of the
preceding abuses, have it looked at by an authorized service center.)
• Do not expose the unit to splashing or dripping liquid. Do not place liq-
uid filled objects on the unit.
• NEVER set the amplifier on a support that will not bear its weight.
• Always keep the total speaker impedance at or above the rated load.
• Unplug the amplifier before cleaning it. NEVER spray liquid cleaners
onto the amplifier. Wipe it with a slightly dampened, lint-free cloth to
remove dirt and film.
• DO NOT use the amplifier if it has sustained damage to the chassis,
controls, or power cord. Refer the unit to an authorized service center
for inspection.
• Prolonged exposure to high volume levels may cause permanent hear-
ing loss or damage. Such damage is progressive and irreversible!

The Front Panel:
1: INPUT: Use this 1/4” jack to connect your guitar to the amplifier by
means of a shielded instrument cable.
2: LEVEL: Use this control to adjust the overall output of the amplifier.
3: LOW: Use this control to adjust the bass response of the amplifier.
Rotating the control counterclockwise reduces the low frequency output.
Rotating the control clockwise increases the low frequency output. It may
be necessary to reduce the Low control at higher volume levels.
4: MID: Use this control to adjust the midrange response of the amplifier.
Rotating the control counterclockwise reduces the midrange frequency
output. Rotating the control clockwise increases the midrange frequency
output.
5: HIGH: Use this control to adjust the high frequency response of the
amplifier. Rotating the control counterclockwise reduces the high fre-
quency output. Rotating the control clockwise increases the high fre-
quency output.
6: SPEAKER: Use this jack to connect the amplifier to an external speak-
er. The internal speaker is disconnected when this jack is used. The
impedance of the external speaker must be 4 ohms or greater.
WARNING: Do not attempt to use headphones in the Speaker jack!
Permanent hearing damage could result!

7: HEADPHONES: Use this jack to connect headphones to the amplifier.
The internal speaker is disconnected when headphones are used.
CAUTION: To avoid possible damage to your hearing, do not use
headphones for extended periods of time at extremely loud levels.
8: ON LED: This LED illuminates when the amplifier is turned on.
9: POWER: Use this switch to turn the amplifier on (top of the switch
depressed) and off (bottom of the switch depressed).
10: POWER CORD (rear panel, not shown): The grounded power cord
should only be plugged into a grounded power outlet that meets all appli-
cable 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.
