Vissonic VIS-PTA-T: Analog array microphone unit
Model VIS-PTA-T
Overview
Analog array microphone unit designed to deliver high voice intelligibility without requiring a gooseneck.
The corridor-type polar pattern and ARRA‑Tech technology create a personal pickup zone of 60–80 cm around the user.
Its low-profile and compact design avoids blocking the line of sight between participants and cameras in conference rooms.
It integrates easily with VISSONIC dB‑NET DSP matrices or any mixer that provides 48 V phantom power through its XLR output.
