Audibax ADI-10M - 2-channel passive stereo DI box with Jack/RCA/minijack inputs and XLR outputs

The Audibax ADI-10M is a passive two-channel (stereo) direct box designed to integrate high-impedance sources—instruments, players, computers, or mobile devices—into professional systems with low-impedance XLR inputs. It incorporates two audio transformers capable of handling high levels without distortion, a switchable 0/-15 dB pad for adapting hot signals, and a ground-lift switch to mitigate ground loop noise. It offers unbalanced 1/4" jack (L/R), stereo RCA, and 3.5 mm mini-jack inputs , with male XLR (L/R) outputs , in a compact 115 × 84 × 46 mm and 435 g form factor. Being passive, it requires no external power supply .

Main features

• Versatile connectivity: 6.35 mm jack (L/R), stereo RCA and 3.5 mm minijack inputs; XLR male outputs (L/R).
• Passive 2-channel design: low impedance conversion using transformers (no external power supply).
• Level and noise control: pad 0 / –15 dB + Ground-Lift to eliminate ground hum.
• Professional compatibility: input impedance >> 130 kΩ and balanced output impedance 600 Ω .
• Compact format: 115 × 84 × 46 mm and 435 g for use in stages, studio, corporate AV and rental.

Product benefits

• Instant integration: connect consumer instruments and players to XLR mixers and stageboxes without loss of quality.
• Clean and controlled signal: transformers isolate and adapt the impedance; the pad prevents saturation; the Ground-Lift reduces hum.
• Live and installation flexibility: multiple physical inputs per channel to resolve last-minute incompatibilities.
• Reliability: Robust passive design, no need for batteries or phantom power.

Use cases

• Musicians and backline: keyboards, basses or multi-effects to PA/monitors with adequate level and without noise.
• Events and AV: connecting laptops, tablets or players to balanced audio consoles.
• Study/test: adaptation and isolation of unbalanced sources in patchbays and interfaces.

Frequently Asked Questions

• Does it need power? No. It's passive ; it works without batteries or phantom power.
• Can I use a single stereo source? Yes. Use RCA or 3.5 mm minijack for L/R; each channel outputs via its corresponding XLR .
• What is the pad for? It reduces the signal by -15 dB to prevent clipping on the XLR input when the source is very loud.
• Does Ground-Lift eliminate all noise? It helps break ground loops; if they persist, check wiring and ground differences.

Usage recommendations

• Start with the pad at 0 dB and activate it if the console indicates saturation or if the source is very high.
• If hum appears, try the Ground-Lift ; use balanced cables from the XLR outputs to the mixer.
• Adjust the source level to maintain dynamic range without distortion.
