The Brick DI box and instrument preamp is designed for both stage and studio. The preamp allows for isolated balanced low impedance output for all instruments and provides either unity gain or use the variable output level control for up to 55dB of all tube gain! The Brick preamp offers perfect tube tone and isolaton for vintage keyboards, electric bass and acoustic/electric guitars with internal transducer type pickups. Onboard phantom power allows the use of high quality condensor mics on stage.

The Brick preamp will noticeably improve the tone of all common stage mics, either dynamic, condenser or wireless. The Brick's 3 internal tubes and massive custom output transformer can drive a signal 100's of feet with no loss and improve any performance. Now you can get studio grade tone and performance on any stage. You will find this especially helpful for those instrument wireless systems that can sound thin. The Brick preamp shrugs off that thin wireless tone and replaces it with Fat!

In the studio.
With Phantom power, and true transformer output, plus an available gain of +55db, The Brick will handle dynamic mics, condensor mics, and ribbon mics.

On the stage
With onboard phantom power, you can now use higher grade large diaphragm mics on stage. Forget about those long cable runs back to the "house system" or house console, The Brick can run 1000 feet and more without the losses of simple direct boxes.
