Designed for high-stakes environments—including government secretariats, corporate boardrooms, and luxury hotel conference halls—it manages up to 255 wireless delegate and chairman units with near-zero latency. By utilizing UHF frequency transmission, it ensures noise-free communication while bypassing the aesthetic and logistical hurdles of traditional wired setups.

► Integrated Feedback Suppression: Built-in technology automatically identifies and eliminates “howling” or feedback loops, ensuring that your audio remains intelligible and professional even at high volumes.

► Digital Signal Processing (DSP): The software-based DSP allows for precision tuning of the audio profile via PC connectivity, ensuring the output is optimized for the specific acoustics of your room.

► Automatic Camera Tracking Compatibility: When paired with the DCW-8504VP Video Tracking Unit, the host unit facilitates automatic camera focusing on the active speaker—essential for modern hybrid meetings and live streaming.
