The RME I64 MADI Card provides the RME ADI-8QS with a 64-Channel MADI input and output. There is also an I64 card available for the RME Micstasy. Please note, these are two different products, so select the alternative item if you require the MADI option for the Micstasy.

The RME I64 MADI Card features an optical as well as a coaxial MADI input. The input is switched automatically, according to where a valid input signal is detected. Full redundancy is ensured by the automatic input switching, immediately changing to the other input in case of loss of the input signal.

The MADI input will operate as an optional clock source (Clock section, OPTN) as well as a thru-input. Since each ADI-8QS or Micstasy uses only 8 channels, up to 56 channels can be passed through. This technique is used to serially cascade several ADI-8QS or Micstasys. Incoming MADI data is passed through unchanged, only one block of eight channels is replaced. This allows up to 8 devices to be connected serially. All 64 combined channels are available at the last device's MADI output.

When multiple devices are connected serially, the MADI I/O of each ADI-8QS or Micstasy causes a delay of 3 samples. Therefore at the MADI output of the last device, the data of all upstreamed devices are delayed. The problem of this offset is solved by the function Delay Compensation.
