Definitive Audio Da UHF MH 200

A modern RF system designed for versatility on stage and at events

This wireless microphone system follows the logic of current RF setups: a two-channel receiver paired with dedicated transmitters, offering a complete solution for both vocals and more "field" uses. Thanks to PLL synthesis (phase-locked loop), oscillator management aims for better stability, particularly useful in environments where radio signals may be challenged (multipurpose rooms, bars, stages, places of worship, conferences).

The inclusion of a handheld mic and a bodypack (for lavalier or headset mic) places this pack in a very practical approach: a single kit to cover two performance styles without imposing a single way to capture the voice.

Who is it for and what are the use cases?

This system targets users seeking a wireless solution that is simple to deploy, with a stated range up to 60 m in open field (line-of-sight distance). It is particularly suitable for hosts, speakers, singers, and technical teams needing a handheld mic for direct interaction while retaining the option of a bodypack for hands-free performance (presentations, coaching, fitness, theater, mobile interventions).

Note: as indicated, the actual range strongly depends on the environment (absorption, reflections, RF interference). In a room filled with metal structures, lighting, wireless networks, or a dense audience, radio behavior may vary. The goal is therefore to have a system designed to remain usable while respecting best practices for receiver and antenna placement.

Key features: RF stability, quick reading, adapted capture for every situation

PLL synthesis + FM modulation: a solid foundation for transmission

The receiver and transmitters rely on PLL frequency synthesis (phase-locked loop) combined with FM modulation. This architecture is common in RF systems intended to combine stability and coherent audio output, especially when alternating between speech and singing.

Mute control: cleaner operation between takes

The receiver includes a silent control mode based on an audio code and noise lock. Practically, this aims to limit the appearance of unwanted noise when the useful signal is absent, for more comfortable listening on a sound system or mixing console.

Two transmitter formats to suit your performance

The handheld microphone features a cardioid polar pattern (heart-shaped capsule): practical for prioritizing the user's voice and reducing some sounds coming from the rear, useful in hosting and on stage. The bodypack offers a more discreet and mobile approach, compatible with a lavalier or headset mic, with adjustable gain to set the level according to the mic used and voice intensity.

LCD display: settings and control at a glance

The receiver combines LCD + LED for quick information reading, while each transmitter has its own LCD screen. In practice, this readability facilitates operation: preparation before use, verification during use, and faster identification in the control room.
