Omnitronic LH-055 PRO DI-Box passive

Stable Connection - Anytime, Anywhere!

The Omnitronic LH-055 PRO passive DI-Box reliably converts unbalanced instrument or line signals into balanced XLR signals. That ensures your signal reaches the mixer cleanly and free from interference - ideal for live gigs, studio sessions or mobile setups. With a switchable input attenuator, rugged housing and instrument pass-through, you stay flexible and professionally equipped.

Signal Conversion at the Highest Level

The LH-055 PRO accepts unbalanced signals via the high-impedance 6.3 mm jack input - from guitar, bass, keyboard or line-level sources. Internally, a high-quality transformer converts the signal to a low-impedance, balanced XLR output. This lets you run the signal over long cable runs to the mixer or PA with strong resistance to interference. A 6.3 mm jack link output is also available so you can pass your instrument through directly - handy for parallel use with an amp and mixer, for example.

Maximum Flexibility With Attenuation and Ground Lift

Depending on signal strength, you can set the input attenuation to 0 dB, -20 dB or -40 dB. This lets the box handle both quiet signals with sensitivity and hot signals cleanly - reliably preventing distortion or clipping. The integrated ground-lift switch eliminates hum loops and ensures a clean, professional connection - especially important when setups change or you connect devices with different grounding potentials.

Robust, Compact and Practical

The sturdy metal housing makes the DI box resistant to mechanical stress - ideal for live use, touring, DJ gigs or frequent re-patching in the rehearsal room. With compact dimensions and low weight, it fits easily into gig bags, cases or rack boxes. No power supply is required - the passive design keeps operation simple and reliable.

Versatile Applications for Musicians and Sound Engineers

Whether you're a guitarist, bassist, keyboardist, DJ or sound engineer, the LH-055 PRO is a universal solution when you need clean, interference-free signals. For live shows, recording sessions, installations or mobile sound reinforcement - this DI box has you covered so you can focus on what matters: your sound.
