Overview
Studio Technologies M232, Announcer’s Console with Dante Audio-over-Ethernet
The Model 232 Announcer's Console provides a combination of high-performance audio with an extensive set of user features and configurable resources. The unit is intended for use in demanding broadcast sports, eSports, live event, entertainment, and streaming broadcast applications. With a few simple connections, the Model 232 can provide one on-air talent with all the resources needed to support a wide range of applications. The compact, rugged steel enclosure is intended for tabletop use, small enough for use "court-side" or in a crowded booth, yet flexible enough for remote production deployment. The Model 232 supports Dante® audio-over-Ethernet digital media technology with AES67 compatibility for integration into contemporary applications.
