Behringer DI10P DI box

Passive DI Box for Consumer and Line-Level Sources

The Behringer DI10P is a compact passive direct injection box that converts stereo consumer-level signals into a clean, balanced mono feed for a professional mixing console. Because the unit draws no current from the desk and runs entirely on its internal transformer, it needs no phantom power, batteries, or external supply — plug it in and it works. The DI10P accepts the typical outputs of laptops, MP3 players, CD players, keyboards, and drum submixers and delivers them straight to a single balanced XLR input on the desk.

What Sets the DI10P Apart

What makes this model stand out is the custom-built MIDAS transformer at the heart of the signal path, paired with a fully transformer-isolated topology that rejects ground loops and keeps the noise floor extremely low. The compact aluminium housing with protective rubber corners is built for the road, so the box can live in a gig bag and survive setup after setup.

Inputs and Signal Routing — Stereo to Mono

The DI10P accepts stereo consumer-level sources through a 3.5 mm jack and RCA inputs, then sums them to a single balanced XLR output that any professional console can lock onto over long cable runs. This stereo-to-mono conversion makes it ideal for click tracks, backing tracks, and stereo playback devices that need to land on one desk channel.

• Inputs: 3.5 mm jack, RCA — covers laptops, phones, media players, and home-audio sources
• Output: Balanced XLR — long-cable-ready feed for any professional mixer
• Signal Flow: Stereo input summed to mono — one desk channel for stereo playback material

Transformer Isolation — No Power Required

A passive design means the DI10P draws nothing from the console: no phantom power, no batteries, no wall adapter. The custom MIDAS transformer handles the impedance balancing and ground isolation in a single stage, which is what allows the unit to deliver ultra-low-noise performance without any active circuitry in the signal chain.

• Transformer: Custom-built MIDAS — handles balancing and ground isolation passively
• Power: Passive operation — no phantom power, no batteries, no external supply
• Noise Performance: Ultra-low-noise, fully transformer-isolated design — rejects hum and ground loops

Controls and Road-Ready Construction

Front-panel controls give the engineer the essentials: a Ground Lift switch to break hum-causing ground loops between source and desk, and a Level control to match consumer-level output to professional line-level inputs. The compact aluminium enclosure with protective rubber corners keeps the unit light enough for a gig bag yet tough enough for repeated load-ins and classroom use.

• Controls: Ground Lift, Level — solve hum and match levels on the fly
• Construction: Compact aluminium housing with rubber corners — built for transport and stage use
• Use Cases: Live sound, rehearsal rooms, education, multimedia — fits any setup that needs a stereo source on a mono channel
