Omnitronic LH-045 is a compact microphone preamp that supplies 48V phantom power and basic gain control for condenser microphones. Designed for studio recording, live sound reinforcement, podcasting and field recording, the unit provides clean signal conditioning and a practical interface for both professional and home audio setups. The preamp is intended to ensure microphones receive stable phantom voltage while allowing the user to adjust input level before the signal reaches the mixer, audio interface or recorder.

Advantages

The preamp offers stable 48V phantom power suitable for most condenser microphones and delivers low-noise amplification with straightforward gain adjustment. Its compact footprint makes it easy to integrate into small rigs or portable recording setups, and its simple controls reduce setup time. The unit is built for reliable everyday use and provides consistent powering and preamplification without complex routing or configuration.

Key specifications

How to use

Connect a condenser microphone to the microphone input and ensure the unit is powered. Activate the 48V phantom power if required by the microphone. Route the preamp's output to a mixer, audio interface or recorder using an appropriate cable. Adjust the gain control while monitoring levels on the downstream device or through headphones to avoid clipping and to achieve the desired input level. Turn off phantom power before disconnecting microphones that do not require it.

Recommendations

Use balanced cables and keep cable runs as short as practical to minimize interference. Confirm microphone compatibility with 48V phantom power before connecting vintage or ribbon microphones. Allow the unit to warm up briefly after powering on for stable performance, and set gain conservatively to preserve headroom and reduce noise.
