The Avid SRO-192 Analog Output Expansion Card is designed for Avid VENUE Stage Racks (like the Stage 64), providing 8 channels of balanced analog line-level outputs via XLR connectors for live sound systems. Used to increase the total output capacity for monitors or FOH feeds, supporting 24-bit audio, and fitting into the modular system to customize I/O. Multiple SRO-192 cards (up to six) can be installed into a single Stage Rack for significant analog output expansion, complementing other input/output cards like the SRI-192 (input) or DSO-192 (digital).
