The Yamaha MY16-C CobraNet Mini-YGDAI Card is a specialized digital interface card designed to integrate high-channel-count, low-latency audio networking into compatible Yamaha digital mixing consoles and processors. As part of Yamaha's Mini-YGDAI (Yamaha General Digital Audio Interface) expansion system, this card slots into a designated slot on consoles such as the LS9, M7CL, and PM5D, or processors like the DME series, instantly providing them with bidirectional CobraNet connectivity. This capability bridges the console's internal digital audio bus with a standard Ethernet network, enabling the transmission and reception of multiple channels of uncompressed digital audio over long distances using common network infrastructure.

The primary function of the MY16-C is to facilitate scalable audio distribution in installed and live sound environments. It allows a Yamaha console to send discrete mixes to remote powered speaker systems or amplifier racks, receive inputs from satellite stage boxes located far from the front-of-house position, or interface with other CobraNet-enabled equipment like digital routers and recording systems. The card typically supports a configurable number of audio channels (e.g., 16x16 in a bidirectional flow) within a single CobraNet "bundle," with performance dependent on network quality and latency settings.

This expansion card exemplifies the modular philosophy of Yamaha's professional audio systems, allowing users to add specific networking functionality as needed without replacing the core console. Its integration is designed to be straightforward, with control and configuration accessible directly from the host console's interface. By adopting the widely used CobraNet standard, the MY16-C card played a crucial role in the transition from analog multicore systems to networked audio, providing reliability and flexibility for complex system designs in theaters, houses of worship, convention centers, and touring productions during its era.
