solid state electronics add up to create one very roadworthy, stage-ready piece of gear.
The BFX-220H packs solid state performance and easily accessible digital effects into a compact head unit,
housed in a rugged Tolex
®

just the bottom, but also on the end you set it down on in real life situations) increase its value to those performers
who are always on the go.
The BFX-220H delivers 220 watts into 4 ohms and 150 watts into 8 ohms. Several of the amplifier’s outstanding
features are listed below.

• Variable input gain control with -15dB pad switch and 3 input icon LEDs for the best match
between your bass and the amplifier

can be turned on and off by means of the supplied single button footswitch
• Balanced line out jack with level control and pre/post-EQ switch
• Headphones jack with level control for practicing in private
• Effects loop for noise-free connection of your favortie processors and effects

Important Safeguards and Precautions:
All Crate products are designed for continuous safe operation, as long as common sense is used and steps are taken to help avoid certain prob-
lems. 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.)
• NEVER set the amplifier on a support that might give out under 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.
• Amplifiers capable of producing high volume levels are also capable of inflicting permanent hearing loss or damage, if the exposure
to such levels is prolonged. Such damage is progressive and irreversible! Consider using quality hearing protection devices.
