Studiomaster Vāk 20 Automatic Conference Mixer

Studiomaster Vāk 20 Automatic Conference Mixer

The Studiomaster Vāk 20 is a high-performance, 8-channel automatic conference mixer engineered to deliver flawless audio management in professional discussion environments. By utilizing intelligent voice-activation algorithms, it eliminates the need for a manual operator, ensuring crystal-clear speech intelligibility and preventing acoustic feedback. This rack-mountable DSP solution is the primary choice for mission-critical boardrooms, legislative houses, and high-security government assembly halls across India.

What is the Studiomaster Vāk 20?

The Vāk 20 is a specialized automatic mixer that bridges the gap between traditional audio mixing and intelligent conferencing logic. Unlike standard mixers, it monitors all eight input channels simultaneously, activating only the microphones currently in use while attenuating inactive ones. This reduces the accumulation of ambient noise and prevents the “hollow” sound typically caused by multiple open microphones in a reflective room. It serves as the central audio processor that allows standard microphones to function as a sophisticated, automated discussion system.

Key Features & DSP Technology

• Intelligent Auto-Mixing Logic: Automatically manages the floor audio by gating microphones in real-time based on voice activity detection.
• Advanced NOM Management: Supports a Maximum of 6 Open Microphones (NOM), ensuring the system remains stable and free from feedback loops even during heated debates.
• Logic Outputs for Automation: Features dedicated Logic Out ports to trigger external hardware, such as PTZ cameras for automatic speaker tracking or lighting control systems.
• Daisy-Chain Scalability: Equipped with Link In and Link Out ports, allowing multiple Vāk 20 units to be cascaded for large-scale conferences requiring dozens of microphones.
• Ambient Noise Compensation: Includes selectable settings for Noisy, Normal, and Quiet environments to optimize the gating threshold according to room acoustics.
• Integrated Signal Protection: A built-in limiter on the output section prevents signal clipping, protecting downstream amplifiers and speakers from sudden volume peaks.

Technical Specifications

Applications & Use Cases

The Vāk 20 is specifically designed for environments where audio reliability and automation are paramount:

• Government & PSU Boardrooms: Provides an orderly discussion environment for executive committee meetings.
• Legislative Assemblies: Manages large microphone counts with cascaded units for democratic debate.
• Courtrooms: Ensures clear recording of proceedings with automatic microphone gating.
• Educational Institutions: Ideal for university senate halls and large lecture theatres.
• Hybrid Video Conferencing: Integrates with camera tracking systems via logic outputs for a professional remote experience.

Role in Complete Conference System

The Vāk 20 acts as the “Audio Brain” of the conference room. It receives signals from gooseneck, lapel, or handheld microphones through its 8 combo inputs. Using its internal logic, it determines which delegate is speaking and routes that signal to the main PA system, recording device, or video conferencing codec. By utilizing the Logic Out ports, the Vāk 20 can inform a camera controller exactly which microphone is active, allowing a PTZ camera to automatically frame the speaker without any manual switching.

System Compatibility & Expandability

The Vāk 20 is a highly flexible platform that supports:

• Standard Microphones: Any dynamic or condenser microphone (+48V) can be connected.
• Unit Linking: The Link In/Out section allows for massive scalability. By daisy-chaining multiple Vāk 20 units, integrators can support 16, 24, or even 48+ microphones under a single master control logic.
• Chairman/Delegate Priority: Each channel can be toggled between “Delegate” or “Chairman” mode, allowing the chairperson to have override capabilities.

Installation & Best Practices

For optimal performance, the Vāk 20 should be installed in a standard 19-inch equipment rack. AV integrators should use the built-in LF (Low Frequency) Cut to eliminate room rumble and the HF (High Frequency) Cut to reduce hiss and sibilance. Setting the ambient noise switch (Noisy/Normal/Quiet) correctly is critical to ensure the gating threshold perfectly matches the room’s noise floor.
