Description

Passive DI Box With High-Quality Transformer For Clean Signal Conversion & Hum Rejection – On-Stage Passive Direct Box

The On-Stage Passive Direct Box is a dependable, no-frills passive DI solution engineered to convert high-impedance unbalanced instrument signals into clean, balanced low-impedance mic-level outputs, ensuring professional-quality transmission over long cable runs with minimal noise and interference. Its high-quality transformer provides transparent sound reproduction while the ground lift switch effectively eliminates hum and ground loops, making it ideal for live performances, recording sessions, rehearsals, schools, churches, or any setup where reliable signal integrity is essential.

The -20 dB pad accommodates hot sources like active basses or keyboards, preventing clipping, and the rugged metal enclosure with rubber feet withstands the rigours of stage use. Compact and lightweight, it fits easily into pedalboards or gig bags—perfect for guitarists, bassists, keyboardists, and sound engineers needing a straightforward, high-performance DI without active power requirements.

Signal Integrity & Noise Reduction

Transformer-based passive circuit preserves tone; ground lift and pad switches solve common live/studio issues like hum and overload.

Build & Practicality

Durable metal housing with secure jacks and switches for reliable touring or fixed installations.
