Bass Amplifier

Congratulations!

Y ou are now the proud owner of the compact but powerful Crate MXB25 Bass Amplifier. The small size
of this amplifier belies its big performance: the 10” Crate Custom speaker makes the most of the amplifier’s
27 watts of musical output power. A4-band rotary EQ combined with Crate’s variable Contour control gives
you complete control over a wide variety of sounds. In addition, the front panel headphone and external
speaker jacks make this amplifier equally suited for practicing as well as perfoming in intimate surroundings.

Like all Crate products, your MXB25 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 urge you to read the information contained
in this manual before you begin playing.

And thank you

for choosing

Important Safeguards and Precautions:

3

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 liq­uid 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 hear­ing loss or damage. Such damage is progressive and irreversible!
