Multifunction Digital Conference System Central Control Unit KRS-20

The KRS-20 is a multifunction digital conference control unit designed to coordinate microphones, discussion modes, attendance, voting, camera tracking, audio processing, and participant services from one centralized platform. Supporting up to 60 conference units directly and scalable system expansion for as many as 5,000 microphones, it provides a flexible foundation for government assemblies, council chambers, corporate boardrooms, command centers, and large professional conference installations.

Products Description

• Centralized conference management: Controls conference microphones, discussion permissions, attendance registration, voting, camera tracking, and audio processing through one integrated unit.
• Flexible microphone capacity: Supports 20 conference units per communication line and up to 60 units directly from one control unit, with a maximum transmission distance of 100 m.
• Large-scale system expansion: Multi-level cascading allows the conference system to be expanded for installations requiring up to 5,000 microphone units.
• Multiple discussion modes: Supports FIFO, FILO, Limited, PC/Chairman Permission, and Free Discussion modes for different meeting procedures.
• Automatic camera tracking: The integrated 4-input / 1-output SDI video matrix can coordinate compatible PTZ cameras to follow active speakers automatically.
• Flexible camera control: RS-232 and RS-485 interfaces support Pelco-P, Pelco-D, and VISCA protocols for direct control of compatible PTZ cameras.
• Integrated attendance and voting: Conference microphones can perform attendance registration and five-key voting directly without requiring a separate computer.
• Dynamic microphone role assignment: Microphone identities can be changed in real time between Chairman, VIP, and Delegate roles according to meeting requirements.
• Participant service requests: Delegates can submit service requests from their conference units, with request information displayed and processed through the built-in color screen.
• Adaptive DSP processing: Integrated digital signal processing suppresses acoustic feedback and improves speech clarity during live discussions.
• Independent tone adjustment: Dual 3-band equalizers allow separate tuning of microphone outputs and conference loudspeaker outputs.
• PC and central-control integration: Communication interfaces enable connection to management software and third-party central control systems.
• Fire alarm integration: A dedicated alarm interface supports connection to compatible fire protection systems for emergency conference audio management.
• Comprehensive audio connectivity: Provides main audio inputs, media-player input, original audio outputs, and processed main outputs with feedback suppression.
