Behringer GI100 Active 1-Channel DI Box with Speaker Simulation

On stage or in the studio, the Behringer GI100 gives guitarists and bassists a reliable way to send a balanced signal straight to the mixing console—no microphone bleed, no ground hum, no compromise. This active DI box takes your instrument's high-impedance output and converts it into a clean, low-impedance XLR signal that can run hundreds of feet without losing clarity. A built-in speaker simulator lets you capture the character of a mic'd cabinet even when you're going direct, making it a favorite for live sound engineers and home recordists alike.

Why choose it

The GI100 isn't just a utility box—it's a tone-shaping tool. The integrated speaker simulation adds the warmth and punch of a 4x12 cabinet to your direct signal, so your amp-less rig still sounds like the real thing. With its rugged metal housing and flexible power options, it adapts to any setup, from a small club PA to a professional recording console.

Ideal use cases

• Live performance: run your instrument directly to the front-of-house mixer
• Studio recording: capture clean DI tracks alongside a miked amplifier
• Reamping: use the link output to send a dry signal to your amp while recording the processed XLR
• Keyboard and acoustic instruments: balance any high-impedance source

Good to know

The GI100 automatically switches to phantom power when available, saving battery life. If you're using a pedalboard with a 9V supply, the battery compartment is easily accessible for quick changes. The ground lift switch is essential for eliminating hum in venues with dirty power, and the -40 dB pad handles even the hottest active pickups without distortion.
