Studiomaster Vāk 30.D Delegate Unit: Professional Wireless Conference Microphone
The Studiomaster Vāk 30.D is a high-performance wireless delegate microphone unit engineered for modern conference environments. Designed for corporate executives, government officials, and educational panels, this unit facilitates clear participant communication without the constraints of wired cabling. In professional AV installations, it serves as the primary interface for attendees to engage in structured, high-intelligibility discussions.
What is the Studiomaster Vāk 30.D?
The Vāk 30.D is the participant-facing component of the Vāk 30 Wireless Conference System. While the Vāk 30.S main controller acts as the central intelligence of the ecosystem, the Vāk 30.D units provide the scalable wireless backbone for up to 50 participants. Each unit is equipped with a sensitive microphone capsule and a robust UHF transmitter, ensuring that every voice is captured and transmitted to the central system with absolute fidelity and zero signal dropouts.
Delegate Participation & FIFO Logic
The Vāk 30.D operates under a sophisticated “First-In-First-Out” (FIFO) logic controlled by the main system. This ensures that participation remains structured and professional, even in heated debates.
- Controlled Entry: Participants enter the discussion in the order they press their talk switches.
- Automated Queue Management: When the maximum number of open microphones (NOM) is reached, the earliest activated microphone automatically mutes to allow the next request to go live.
- Productive Flow: This technology eliminates audio clutter and ensures that no more than three delegate units (plus one chairman) are active simultaneously, preserving acoustic stability and listener focus.
Key Features & Technology
21-Inch Flexible Gooseneck
The extended length and 2-bend design allow delegates to position the microphone perfectly regardless of seating height, ensuring consistent audio pickup.
Status-At-A-Glance LCD
Integrated screen displays battery level, unit ID, and channel number, allowing delegates and technicians to monitor hardware health in real-time.
Dual Power Resilience
Can be powered by standard AA batteries for total mobility or via a DC adapter for permanent boardroom installations, offering fail-safe operation.
LED Activity Ring
A bright red ring at the microphone head provides immediate visual confirmation when a unit is live, preventing “silent speaking” errors.

Applications & Use Cases
System Compatibility & Scalability
The Vāk 30.D is fully compatible with the Vāk 30.S Controller and the Vāk 30.C Chairman Unit. A single system supports up to 50 wireless units (1 Chairman + 49 Delegates). The NOM (Number of Open Microphones) management allows for up to 3 delegates to speak simultaneously with the chairman, providing a total of 4 active microphones at any given time to prevent acoustic feedback.
Installation & Best Practices
For high-authority AV integration, position the Vāk 30.S controller with a clear line-of-sight to all Vāk 30.D units. Maintain antennas at an elevated position to ensure the full 60-meter radius is utilized. In Indian environmental conditions, ensure the units are stored in well-ventilated spaces to preserve the high-quality microphone capsules and digital processing components during long-duration sessions.
