Audibax ADI-10A - 48V Active DI Box with Phantom Power, Extended Headroom and Transformer Isolation

Audibax ADI-10A - 48V Active DI Box with Phantom Power, Extended Headroom and Transformer Isolation

The Audibax ADI-10A is an active, 48V phantom -powered DI box designed to deliver balanced, clean, and high-dynamic-range line/mic level instrument signals. It features an internal digital switching power supply that boosts the rail voltage from the phantom power, allowing it to handle transients up to 9V without overpowering, resulting in reduced distortion on peaks and square waves . Additionally, it includes an isolation transformer that helps eliminate ground loops and system noise , ensuring a stable signal in both live and studio environments.

With a 1/4” jack input , male XLR output , switchable 0/−15 dBu pad and Ground-Lift switch , the ADI-10A offers the essential connectivity and controls you need for guitars, basses, keyboards, drum machines , players and other high impedance sources, delivering a suitable and balanced level for consoles, interfaces and preamps.

Main features

• 48V phantom power supply with internal digital switching power supply that boosts the rail voltage.
• Extended headroom : handles transients up to 9V to preserve dynamics.
• Transformer isolation : helps eliminate hum from ground loops and harsh noise.
• Connectivity : 1/4” Jack input and balanced male XLR output.
• Controls : Pad 0/−15 dBu and Ground-Lift switch for noise adjustment and reduction.
• Optimized impedances : input > 220 kΩ, output 600 Ω.
• Compact and robust format : 127 × 87 × 46 mm , 420 g .

Product benefits

• Cleaner and more consistent signal on long runs thanks to the balanced XLR output and transformer isolation.
• More dynamic, less saturation : the greater headroom margin prevents cuts in aggressive peaks.
• Immediate professional integration with standard consoles, interfaces and stage boxes .
• Noise control : switchable pad and ground-lift to adapt levels and break ground loops.
• Portability : small size and phantom power, no batteries or external adapters required.

Use cases

• Direct : Connect guitar, bass, keyboard or player to the front-of-house with stability and low noise.
• Studio : clean injection to preamps/interface from active boxes, synths and drum machines .
• Backline and rental : universal solution for stages, rehearsals and mobile productions.

Frequently Asked Questions

• Does it need batteries or an adapter? No. It works with 48V phantom power supplied by the mixer or interface.
• Does it reduce hum due to grounding? Yes. The isolation transformer and ground lift help to break common ground loops.
• Does it work for passive and active instruments? Yes. The 0/−15 dBu pad makes it easy to adjust levels on high-output sources.
• What connectors does it include? 1/4” input and balanced male XLR output .

Connections and controls

• Input: 1/4” Jack (high impedance).
• Output: Balanced male XLR (600 Ω).
• Controls: Pad 0/−15 dBu and Ground-Lift switch.
