Shure AMS8000 rackmount automatic mic mixer

These mixers are specifically designed to use Shure's proprietary AMS microphones.   They will work with conventional dynamic mics, however the gate function will not work (Gate stays on).

These mixers work well in a broad range of applications from Conference Rooms, Churches & Synagogues to Council Chambers.   Any situation that requires unattended mixing of multiple mics with varying levels and speakers will benefit from the Shure AMS systems.
