DSPPA D7157 - chairman's microphone console for the D711 conference system

DSPPA D7157 is a professional chairman's microphone console designed to work with the DSPPA D711 digital conference system. The device is intended for conducting conferences, meetings, sessions, and gatherings that require efficient discussion management. The console combines discussion and participant registration functions, ensuring convenient operation and high-quality voice transmission.

Equipped with a cardioid electret condenser microphone, the D7157 model provides effective speech pickup and high resistance to interference. Noise reduction features, automatic gain control (AGC), and software-based 12-band EQ allow for audio parameter optimization depending on the room's acoustic conditions.

As a chairman's unit, the DSPPA D7157 offers a priority function and the ability to approve participants' requests to speak. The device provides full control over the discussion process, and its position in the system is not limited by the installation location. Thanks to power supply from the central unit or PoE switch and connections based on the RJ45 interface, the console integrates perfectly with professional conference installations.
