Digital Series Distribution Board

Availability: In Stock

Condition: New
Brand: Notifier
Status: Active
SKU: 61033
Manufacturer Part #: DS-DB


The DS-DB Digital Series Distribution Board and its associ- ated amplifiers provide bulk amplification capability to the Digital Voice Command (DVC) system while retaining digital audio distribution capabilities. Up to four DS-AMP/E amplifi- ers can supply high-level risers spread throughout an instal- lation.

The DS-DB converts digital audio to analog and routes it to audio amplifiers and optional backups. The amplifiers send back high-level audio, which the DS-DB routes to its risers. Control and status information passes between the DS-DB and its components via DS-BUS. The DS-DB communicates with the rest of the digital audio system through the DAL (dig- ital audio loop), and takes up two of the 32 DAL addresses. It may be mixed with other devices on the same DAL, such as the DAA2 and DAX series amplifiers.
