Behringer Ultra-DI DI100 Active Direct Box - Used
The Behringer Ultra-DI DI100 is a workhorse active direct box built for stage and studio use. It converts unbalanced instrument signals from guitar, bass, or keyboards into clean balanced signals for your console, with the Behringer OT-1 transformer providing ultra-flat frequency response and galvanic isolation. Switchable -20dB and -40dB pads handle hot signals and allow direct connection to speaker outputs on systems up to 3,000 watts. Ground lift switch eliminates hum. Runs off 9V battery or 18–48V phantom power, with the battery automatically decoupling when phantom is connected. Rugged aluminum housing with stackable rubber corners.
This one is in fantastic shape with very light wear — nearly none to speak of. Everything functions normally.
