Can we use it for a conference hall with 100 seat capacity?
VISSONIC wireless handheld microphones provide a reliable operating range of approximately 50-80 meters in open indoor environments, with the True Diversity model offering extended range up to 100 meters.
The product options:
Single Channel Wireless Microphone — standard UHF system, 50-80m typical range. Good for presenter use in medium halls.
True Diversity Wireless Microphone — dual-antenna receiver design that significantly reduces dropouts, extending effective range to 80-100m. Recommended for large conference halls where the presenter may move around.
Dynamic Vocal Microphone — the handheld transmitter itself, with a cardioid pickup pattern that rejects ambient noise.
Practical considerations for large halls:
Mount the receiver antenna as high as possible with clear line-of-sight to the stage area
Avoid placing the receiver near metal racks, LED walls, or large video displays that can cause RF interference
For halls deeper than 80m, consider using an antenna distribution system or placing the receiver closer to the stage with balanced audio cabling back to the mixer
The True Diversity model is strongly recommended for critical applications — it switches between two independent receiver paths to maintain signal integrity
