The RedNet 6 and RedNet D64R both support coaxial and optical MADI in either 'Fixed' (64/32/16) or 'Varispeed' (56/28/14) formats at sample rates of 44.1/48kHz, 88.2/96kHz and 176.4/192kHz respectively.

Both devices feature multi-mode optical fibre chipsets by default (single-mode modifications can be made on request).
