DS 4002 M Master
A single DS 4002 M Master Matrix (19”/1U) is the centerpiece of a basic ASL Digital Intercom system for as many as 40 users. The user stations are connected via five Intercom Line connectors on the rear panel. Each Intercom Line contains the data for a maximum of eight user stations. The Intercom Line connectors also supply +48 VDC over the Cat-5 cable; this power is available to beltpacks and smaller speaker stations that do not have their own power supplies.
