Hardware Overview
The UAD‑2 Live Rack hardware is the 1U rack device that performs audio signal
processing on digital audio streams via MADI optical I/O. The hardware unit contains four
SHARC DSPs that process the UAD Powered Plug‑In algorithms. Each unit can process
up to 16 MADI streams, and up to four units can be combined to process a total of 64
MADI streams. Additionally, each unit has dual‑redundant internal power supplies and
automatic failover protection.
Each UAD‑2 Live Rack hardware unit is configured and controlled by the UAD‑2 Live
Rack software application. The MADI channels being processed by each hardware unit is
specified in the Settings tab in the UAD‑2 Live Rack software.
