Behringer DI800 Ultra-DI PRO V2 — 8-Channel Active DI for Stage and Studio

Behringer DI800 Ultra-DI PRO V2 is an active 8-channel direct injection box built for musicians who need to convert unbalanced instrument signals to balanced mic-level runs without losing tone. Eight independent DI channels share a single 1U rack chassis, replacing a stack of single-box units and keeping the rack tidy. This model is the right choice for live-sound engineers, project studios, and houses of worship that route multiple guitars, basses, keyboards, or playback devices through long XLR snakes to the front-of-house console.

What sets the DI800 V2 apart from typical single-channel DIs

Most direct boxes handle one instrument at a time. This rack unit packs eight servo-balanced channels into a 1U enclosure, each with its own ground-lift switch and illuminated status indicators for dark stage environments. The internal switch-mode power supply accepts 100-240 VAC worldwide, while +48V phantom-power operation lets the unit run from any console's phantom bus when mains power is unavailable.

Signal path and gain staging — clean DI for any source level

Servo-balanced circuitry preserves the source tone across long cable runs, while per-channel gain switches handle everything from quiet acoustic pickups to hot speaker outputs.

• Frequency Response: 10 Hz to 50 kHz (±3 dB) — captures full bass fundamentals and airy high-end without coloration
• Maximum Input Level: +48 dBu — accepts hot line and speaker-level signals without clipping
• Total Harmonic Distortion: < 0.01% at 1 kHz — keeps the converted signal transparent
• With a signal-to-noise ratio of -96 dBu (measured between 22 Hz and 22 kHz), the unit maintains a low self-noise floor suitable for critical studio recording applications.

Per-channel controls — match any instrument on stage

Each of the eight channels carries identical front-panel controls so engineers can patch any source without hunting for the right switch.

• Input Attenuation Pad: -30 dB switchable — tames speaker outputs up to 3000 W feeding the DI input
• Gain Boost: +20 dB switchable — lifts low-output acoustic pickups and vintage preamps to usable line level
• Ground Lift: per-channel switch — breaks ground loops that cause 50/60 Hz hum between stage and FOH

Connectivity and rack form factor — drop-in to any 19" rack

Front-panel 1/4" jacks speed up stage patching, while rear XLR outputs feed the long balanced run to the console.

• Inputs: 8x 1/4" TS unbalanced — front-panel access for fast instrument patching
• Link Outputs: 8x 1/4" TS parallel — feed a stage amplifier or monitor while still sending to FOH
• Main Outputs: 8x XLR 3-pin balanced — gold-plated connectors for long cable runs
• Rackmount Size: 1U, 483 x 134 x 44 mm — fits standard 19" equipment racks
• Weight: 1.8 kg — light enough for fly racks and mobile rigs

Who should put the DI800 V2 in their rack

It is the right choice for live-sound engineers running multi-instrument stages who need eight DI channels in a single rack space. Touring bands, churches, schools, and project studios benefit from the per-channel ground lift, pad, and gain controls that handle guitars, basses, keyboards, and playback devices from one unit. Dual mains and phantom-power operation make it equally useful in fixed installations and mobile rigs where AC power may be limited.
