Premium rackmount MADI-to-SoundGrid interface for recording up to 128 channels at 96kHz. Housed in a 1U chassis, with redundant power supplies and a built-in switch, DiGiGrid MGR is ideal for all high-channel-count MADI recordings. Expanding on the DiGiGrid MGB and MGO audio interfaces, the MGR extends the MADI range. The MGR ships as a Quad BNC MADI interface and an optional optical MADI card can be fitted into the MGR, allowing complete compatibility with any MADI console, in any environment.
