While the Behringer Ultra-DI DI20 Professional Active 2-Channel DI-Box/Splitter may seem like a simple device, it's a powerful tool for musicians who require superior sound quality and versatility. This unique DI (Direct Injection) box is capable of converting two separate unbalanced 1/4" TRS lines into two balanced XLR outputs, offering a solution for reducing unwanted noise and interference. Ideal for electric guitarists, keyboardists, and bassists, the DI20 provides unparalleled flexibility. With a simple flip of a switch, it can serve as a launching pad for two distinct mono signals, a stereo signal, or a split-signal feeding two separate amplifiers. This multi-functionality makes it an indispensable asset for any musician's gear setup.The DI20 is not just about flexibility; it also prioritizes signal integrity. It features a ground lift switch to eliminate hum or buzz caused by ground loops, and a 3-position input attenuator that can handle input levels of up to +48dBu. This built-in attenuator allows you to safely connect to your amplifier's speaker outputs, even those rated as high as 3000 Watts.Powering the DI20 is as flexible as its functionality. It can be powered by either a 9V battery for portability or your mixer's phantom power supply (+18 to +48V DC) for convenience. Encased in an ultra-compact, road-suitable, and rugged metal housing, the DI20 is built to withstand the rigors of touring and frequent use. For working musicians seeking uncompromising functionality, durability, and affordability, the Behringer Ultra-DI DI20 Professional Active 2-Channel DI-Box/Splitter is a sound investment.
