'Super Multi-channel Audio Connection' (SuperMAC) is an enhancement of the existing 'Multi-channel Audio Connection for Direct Stream Digital' (MAC-DSD) to support PCM audio formats, extending the unique benefits of the technology to a universal range of studio audio applications. The link provides full-duplex multi-channel audio connection for Direct Stream Digital (DSD) or 24-bit PCM, at sample rates up to 384kHz, plus high-quality clock signals and auxiliary data. It features error correction and deterministic latency as low as 45 microseconds, and the connection medium is a standard structured wiring cable. The specification is being submitted to the AES Standards Committee with a view to open standardisation.
