About: DBX DriveRack 4820 Loudspeaker Management System

Loudspeaker Management System The 4820 includes four inputs and
eight outputs with both analog and digital connectivity. The 96 kHz
processing engine is capable of offering insert processing functions to
customize the processing path for your application, in addition to the
standard system processing functions all with extremely low latency
and extended frequency response. From Signal Routing, EQ, and
Bandpass Filters, to classic dbx® Dynamics and Feedback Suppression.
