Extend Yealink video-conferencing room audio across larger tables or distributed seating with four wireless microphone arrays. The VCM36 W Pro package supports full-duplex audio, allowing participants to speak and listen at the same time, while noise reduction helps keep conference speech intelligible. It fits conference rooms where one microphone location cannot serve every participant position effectively. The four-array configuration permits microphone placement at multiple points in the room instead of concentrating pickup at one end of a table. Wireless operation helps support flexible placement without routing a microphone cable to every position. Full-duplex operation matters in active meetings, where interruptions, questions, and overlapping responses need to remain audible in both directions. Yealink 1303291 packages four microphone arrays for conferencing installations that require distributed room-audio coverage. It is differentiated by its four-array bundle, rather than a single microphone arrangement, and by the combination of wireless microphone operation, full-duplex audio, and noise reduction. Use it where room layout, table length, or participant distribution calls for multiple microphone positions.
