CS-302D

CS-302D is the delegate microphone unit of the CS-302 conference system – a simple and cost-effective solution for meetings, discussions, and formal sessions. It features a high-definition OLED screen that displays microphone status, operating mode, and other key information in real time. The built-in speaker allows direct audio playback, while the 3.5 mm headphone output provides private listening.

The unit supports four operating modes, including a newly developed voice-activated (VOX) mode that enables hands-free microphone activation by simply speaking. A status indicator shows whether the microphone is active, muted, or in a waiting state. The system allows 2, 3, or 4 microphones to be active simultaneously, and up to 110 units can be connected using the EXP-124 expansion module.
