The CS-115R (often paired with EG-115 microphones) is a professional central controller/receiver for wireless and wired conference discussion systems. It serves as the “brain” of the setup, managing the communication between the chairman and delegate units.
Core System Features
Centralized Control: Manages up to 45–60 microphone units depending on the specific configuration.
Multi-Mode Operation:
FIFO (First-In-First-Out): Automatically rotates active microphones when the limit is reached.
Voice Activated: Mics activate only when speaking, reducing ambient noise.
Chairman Priority: Allows the chairman unit to override and mute all delegate units instantly.
Audio Protection: Built-in high-pass filters and auto-gain circuits prevent low-frequency rumble and feedback.
Expandability: Can be integrated with the VTS-1000 video tracking system to automatically focus cameras on the active speaker.
