Studiomaster Vāk 40.S Wireless Conference System Controller
The Studiomaster Vāk 40.S is the central control unit of the Vāk 40 wireless conferencing ecosystem. Designed for professional boardrooms, legislative chambers, and institutional meeting spaces, it manages wireless microphones, camera tracking, and digital voting workflows. By combining UHF wireless architecture with DSP processing, it ensures controlled discussions, accurate documentation, and efficient decision-making.
What is the Vāk 40.S Controller?
The Vāk 40.S functions as the operational brain of the system, coordinating communication between chairman and delegate units while managing RF channels and meeting logic. Built on a wireless UHF platform, it eliminates complex cabling while maintaining stable signal performance. Integrated DSP processing enhances speech intelligibility, and centralized system controls allow administrators to configure operating modes, microphone activity, and camera switching.
Core System Capabilities:
▪ Camera Tracking Integration: Supports VISCA and PELCO D/P protocols with RS-232 and RS-485 interfaces, enabling automatic camera switching to active speakers for professional meeting coverage.
▪ Digital Voting & Sign-In: Streamlines decision workflows with participant authentication and structured voting processes.
▪ USB MP3 Recording: Built-in recording captures meetings sequentially, simplifying documentation and compliance.
▪ NOM Logic: Supports up to four active microphones simultaneously to maintain discussion discipline.
▪ Operating Modes: FIFO, LIFO, Limit, and Chairman modes provide flexible meeting control based on procedural requirements.
