The Appsys ProAudio SRC-64 is an optional hardware module designed to enhance the functionality of the MVR-64 Multiverter by providing 64-channel bidirectional, asynchronous sample rate conversion between arbitrary sample rates and interfaces. This capability allows for seamless integration of audio equipment operating at different sample rates without the need for a common master clock, thereby simplifying complex digital audio setups. Featuring high analog performance with a typical Total Harmonic Distortion plus Noise (THD+N) of -133 dB, the SRC-64 ensures pristine audio quality during conversion. It supports a wide range of sample rates, from 32 kHz to 192 kHz, and can handle up to 64 channels per direction in standard modes (44.1/48 kHz), 64 channels per interface in double-speed modes (88.2/96 kHz), and 32 channels per interface in quad-speed modes (176.4/192 kHz).
