Overview
The AMC-20 is an AV controller built to combine automatic microphone mixing and video control in professional conference systems.
It can manage multiple Relacart WAM-432 wireless mixers from a single unit, coordinating audio and PTZ cameras automatically.
Its microphone-driven video tracking logic makes it possible to deploy complete speaker-tracking solutions without relying on complex additional DSPs or matrix switchers.
