Digital Series Distribution Board

The DS-DB Digital Series Distribution Boards and its associated amplifiers provide bulk amplification capability to the Digital Voice Command (DVC) system while retaining digital audio distribution capabilities. The Digital Series Distribution Boards convert 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 EIA-485 bus. They communicate with the rest of the digital audio system through the DAL (digital 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.
