It's a professional and multi-purpose DI box for stage and studio applications, designed to provide impedance and signal matching for instruments connecting to mixers and amplifiers.
It features an internal battery that automatically shuts off when phantom power is applied, and it can directly connect to speaker outputs with up to 3,000 Watts.
The DI100 also includes a switchable attenuation pad for handling high input levels (up to +50 dB) and a ground lift switch to eliminate ground loop noise.
It is known for its rugged, road-proof aluminum case with stackable rubber corners and features Behringer's renowned OT-1 output transformer for full galvanic insulation.
