DXJ112 Digital Guitar Amplifier
Welcome. Please, Read This:
We at Crate extend our sincere “welcome” into a whole new world: a world where the legendary performance of a musician-made Crate amplifier combines with the wonders of digital amp modeling and effects. We bring you the only amplifier you’ll ever need: the Crate DXJ112. The heart and soul of sixteen different amplifiers have been captured through the miracles of digital software engineering and placed into the DX amplifier. Not only does the amp sound like the originals, it performs like the originals, with the same tones and character of all your favorites – from vintage British grit to today’s heavy metal – with a wide variety in between.
Along with digital amp modeling comes sixteen digital effects, all designed to rock your world from here to Sunday. And, you can tweak each effect to your heart’s content!
Got your own favorite effects? Not to worry – the DX amps have stereo line in and line out jacks for use as a stereo effects loop, or for connecting to an external stereo power amp. It’s like having your cake and eating it, too – with extra icing!
The DX amplifier is programmable and can be controlled in a number of ways, including through the front panel keypad, with the optional Crate Foot Controller, or via MIDI.
Within the pages of this Operating Guide you will find all sorts of pertinent, useful and sometimes technical information which we at Crate felt you ought to have. Please indulge us a bit and take the time to actually read through this Guide at some point. Until then, for those of you who just can’t wait to plug in and go, we offer you:
Quick Start: Plug In and Go!
(page 1)
There you’ll find just enough information to get you started. If you run into any situation that isn’t covered in the Quick Start section, you might have to – guitar gods forbid – read this guide first.
We at Crate thank you for choosing the DXJ112 Digital Guitar Amplifier!

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 problems. 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.
