Active DI Box Omnitronic LH-065 1-channel

The Active DI Box Omnitronic LH-065 1-channel delivers a single-channel direct injection interface designed to connect instruments or line-level sources to mixing consoles and PA systems. As an active DI box, it provides impedance matching, balanced output, and low-noise signal conversion to preserve the original tone and reduce signal loss. The unit is intended for both live performance and studio environments where reliable grounding and clear signal transmission are required.

Advantages

The Omnitronic LH-065 offers stable active circuitry that maintains consistent signal level and tonal integrity across a wide range of input sources. Its balanced output minimizes hum and interference over long cable runs, while impedance conversion ensures optimal matching with mixer microphone inputs. The compact single-channel design fits easily into pedalboards or equipment racks and supports straightforward integration into live and studio signal chains.

Suitable for

• Electric guitars and basses requiring direct connection to a mixing desk
• Keyboards and electronic instruments with line-level outputs
• DI use in live concerts, rehearsals, and stage setups
• Recording sessions where a balanced feed to preamps is needed
• Situations requiring ground-lift or hum elimination between devices

Key specifications

• Channels: single-channel active DI
• Input types: instrument and line-level compatible input
• Output: balanced low-impedance XLR output suitable for mic preamps
• Noise performance: low-noise active circuitry for clean signal conversion
• Controls: front-panel level or attenuation control (if present on unit)
• Construction: rugged metal housing for stage and studio use

How to use

Connect the instrument or line-level source to the DI box input using a standard instrument or TRS cable, then run an XLR cable from the DI box balanced output to the mixing console or PA system microphone input. Engage any available ground-lift switch if ground loop hum occurs. Adjust the input level or attenuation control to match the downstream preamp and avoid clipping. For battery- or phantom-powered models, ensure the power source is present and correctly configured before operation.

Usage recommendations

Place the DI box close to the instrument source to minimize unbalanced cable length. When possible, use balanced XLR connections to the mixer and enable ground lift only when necessary. Check power requirements and connections in the setup phase to ensure consistent performance during live or studio sessions.
