The UHF Handheld Microphone Solution: A Must-Have Format in Sound Reinforcement

The UHF wireless handheld microphone has become a standard for performances where freedom of movement is as important as message clarity: hosting, speaking, rehearsals, small stages, or community events. This system follows a logic of simplicity: a dynamic handheld microphone, a dedicated receiver, and quick setup to amplify a voice without cable constraints.

Who and For What Uses?

This system is aimed at those looking for an easy-to-use UHF wireless microphone for spoken or sung voice: hosts, teachers, speakers, presenters, musicians in rehearsal, event organizations, communities, multipurpose rooms, or places of worship. The unidirectional dynamic microphone is particularly suited when you want to maintain coherent pickup, even in simple sound reinforcement contexts.

UHF Transmission Designed to Focus on the Essentials

With its frequency range of 640 to 647.30 MHz, the receiver is designed to provide a stable UHF transmission base, useful in contexts where one must move, speak to an audience, and remain intelligible. The announced frequency stability ensures consistent operation throughout a performance, while overall parameters (deviation and audio dynamic range) aim for usable vocal reproduction in sound reinforcement.

Handheld Microphone: Dynamic and Unidirectional

The microphone is a unidirectional dynamic model, a common choice for stage and hosting due to good tolerance of strong sources and focused pickup. The integrated antenna simplifies daily use, and the 9V battery power supply allows quick replacement between sessions.

Receiver: Flexible Power Supply Depending on Model

The receiver operates with a power supply rated 12 to 18 VDC or 220/50 Hz depending on the model, allowing adaptation to the installation context. Its announced consumption of 3 W makes it a discreet device to integrate into a small control room, a lightweight rack, or a mobile sound reinforcement setup.

Output Level and Performance Indicators

The announced output level of 0 to 2 V facilitates integration with a mixing console, amplifier, or active speaker, depending on the configuration. The SIN ratio and sensitivity values provide a benchmark to assess system performance, useful for choosing a wireless microphone suited to your clarity and stability needs.
