Featuring a thick aluminum housing and stackable, rubber corners to protect the electronics, the Behringer DI100 is a single-channel, active direct injection box built to handle the rigors of the road. Equally suited for both studio use and live applications, this versatile DI box provides impedance and signal matching for the direct connection of an unbalanced line or instrument signal (guitars, basses, keyboards, effect processors, and other line-level devices) to the balanced input of a mixer or amplifier. It can also be used to balance a signal for long cable runs.
