Wireless microphone set Omnitronic FAS TWO with dynamic handheld mic, bodypack transmitter and headset, 660–690 MHz

The Omnitronic FAS TWO wireless microphone set operates in the 660–690 MHz UHF range and combines a dynamic handheld microphone, a bodypack transmitter and a headset microphone in one kit. Designed for live vocals, presentations and speech, the set offers multiple microphone types to suit different performance and speaking situations while maintaining a single wireless receiver ecosystem. The components are matched to provide clear vocal reproduction and straightforward setup for small to medium events, rehearsals and installations where mobility and hands-free operation are required.

Advantages

The set provides three microphone options in one package: a rugged dynamic handheld mic for conventional vocal use, a bodypack transmitter for instrument or lavalier/headset connectivity, and a lightweight headset microphone for hands-free speaking and performance. Operating in the 660–690 MHz band, the system can deliver stable UHF wireless transmission with reduced susceptibility to ambient noise compared with lower-frequency systems. The components are intended for ease of use, with quick swapping between mic types and straightforward integration into basic PA systems.

How to use

Power on the receiver and ensure it is tuned to the same frequency range as the handheld, bodypack and headset transmitters. Install fresh batteries in the handheld and bodypack units according to the manufacturer’s recommendations and connect the headset to the bodypack if required. With the receiver connected to the PA or mixer, set input levels on the sound system and perform a sound check to adjust gain, tone and monitor levels. For handheld vocal use, hold the microphone 5–15 cm from the mouth; for headset use, position the capsule near the corner of the mouth and secure the headband for stable placement. Mute transmitters when not in use to reduce noise and extend battery life.

Usage recommendations

For reliable operation, perform a frequency scan before each event to avoid local RF interference and select an open channel within the 660–690 MHz range. Use fresh batteries and spare packs for uninterrupted sessions, and keep transmitters at a moderate distance from wireless routers and other RF sources. When deploying multiple systems, maintain clear line-of-sight between transmitter and receiver where possible and use the headset for hands-free speaking when mobility is required.
