## Long description

Bitmat WM4 is a wireless headset microphone system that includes four headset transmitters and four bodypack receivers, designed for hands-free vocal pickup and clear voice reinforcement. The system targets multi-user environments where several presenters or instructors need independent wireless headsets that enable mobility and consistent audio pickup during presentations, classes, fitness sessions, small events, and guided tours.
Advantages
The Bitmat WM4 system provides simultaneous support for four users, ensuring balanced and stable wireless transmission for each headset and receiver pair. Its headset transmitters offer close-microphone placement for clear speech capture while leaving hands free for demonstrations or movement. The compact bodypack receivers are portable and unobtrusive, allowing wearers to move around without cables. The system’s design simplifies setup and reduces the need for multiple individual wireless purchases.
Suitable for
 Classrooms and lecture halls for instructors and guest speakers
 Fitness and dance instructors conducting group sessions
 Small events, corporate presentations, and panel discussions
 Guided tours where multiple guides or multilingual commentary is required
Key specifications
 Configuration: 4 headset transmitters with 4 bodypack receivers
 Microphone type: headset condenser capsule positioned near the mouth for vocal clarity
 Operation: wireless transmission suitable for speech reinforcement and live presentations
 Form factor: lightweight headset transmitters and compact bodypack receivers for mobile use
 Connectivity: wireless link between each headset transmitter and its paired bodypack receiver
How to use
Fit the headset transmitter so that the microphone capsule is positioned close to the mouth but not directly in front of it, then attach the corresponding bodypack receiver to clothing or a belt. Power on transmitter and receiver units and confirm the paired wireless connection and audio level before starting the activity. Adjust the microphone position and receiver volume to achieve clear, natural speech without distortion. For group situations, verify each pair individually to ensure consistent performance across all four channels.
Usage recommendations
Place the microphone capsule about 1–2 cm from the mouth and avoid pointing it directly at the lips to reduce plosive sounds. Perform a brief sound check in the actual environment to set appropriate receiver levels and minimize feedback. Keep spare batteries or ensure rechargeable units are charged before use to maintain uninterrupted operation during sessions.
