The Grass Valley A1616AU-P AccaPella is a professional audio routing system designed for broadcast, production, and post-production environments that require reliable and flexible routing of multiple audio signals. It provides a 16×16 routing matrix, allowing any of sixteen audio inputs to be routed to any of sixteen outputs. This makes it suitable for television studios, OB vans, radio facilities, and production control rooms where multiple audio sources such as microphones, mixers, playback devices, and intercom systems must be managed centrally.

As part of the AccaPella routing family, the A1616AU-P is engineered for continuous operation in mission-critical broadcast workflows. It supports clean signal switching without audible artifacts and integrates with Grass Valley routing control systems for centralized management. The compact rack-mountable design allows easy integration into existing broadcast racks, making it a practical solution for facilities that require dependable audio routing without the complexity of large-scale router frames.
