Conversor de linha fono Omnitronic LH-042 com saída RCA e fonte de alimentação 24V

Omnitronic LH-042 is a phono-to-line converter that converts RIAA phono signals from turntables to a fixed line-level output suitable for connection to amplifiers, mixers or recording devices. The unit provides stereo RCA output connectors and operates from a supplied 24V external power supply. The compact chassis and straightforward connectivity make the LH-042 a practical solution for DJs, home audio systems and recording setups that require a dedicated phono preamplifier with RCA outputs.

Advantages

The LH-042 offers a clean phono preamplification stage with RIAA equalization, ensuring accurate frequency response and improved signal level for downstream equipment. With standard RCA outputs the unit integrates easily with consumer and professional audio equipment. The external 24V power supply provides stable operation while keeping the main unit compact and easy to place near playback equipment.

Key specifications

How to use

Place the LH-042 near your turntable and connect the turntable’s left and right RCA outputs to the unit’s phono input jacks. Connect the unit’s RCA line outputs to the amplifier, mixer or recorder’s line-level inputs using quality RCA cables. Plug the supplied 24V power supply into the LH-042 and then into a mains outlet; power the unit on following the manufacturer’s sequence if applicable. Adjust input levels on the downstream device rather than on the converter, keeping the converter's output at a fixed line level. Verify correct channel routing and check for proper grounding to minimize hum or noise.

Recommendations

For best performance, ensure the turntable is properly grounded and the cartridge is aligned and set to the manufacturer’s recommended tracking force. Use well-shielded RCA cables for both input and output runs and avoid running audio cables parallel to mains cabling to reduce interference. If the system exhibits hum, confirm ground connections and try a ground-lift option on the downstream equipment if available.
