DSPPA D7324 - Wireless Conference System 5G WiFi Wireless Discussion Delegate Unit

DSPPA D7324 is a wireless delegate unit for the D73 conference system, designed for professional AV installations in large and multi-room venues. It supports speaking functionality and features a cardioid electret condenser microphone with a dual-color LED ring (red/green) indicating speaking and request-to-speak status. The built-in magnetic speaker automatically mutes when the mic is active to prevent feedback. The unit includes a 2.4" OLED display, 3.5mm headphone jack with volume control, and control buttons.

With WPA/WPA2 encryption and 128-bit AES, D7324 ensures secure communication. It supports roaming between access points, camera tracking, and self-diagnosis, offering high-quality audio and seamless operation. Unlike the chairman unit, it does not include priority or voting initiation functions.
