I64 MADI Card
I64 MADI Card
The I64 MADI Card provides the QS with a 64-Channel MADI input and output. Coaxial and optical output operate in parallel to the AES/EBU and ADAT output, therefore deliver the same data.

The 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 signal source of the DA-converter and as thru-input. Since each QS uses only 8 channels, up to 56 channels can be passed through. This technique is used to serially cascade several ADI-8QS converters. 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.

With an installed I64 MADI Card the QS can also be remote controlled via MADI. At the same time MIDI data are transmitted via MADI. When multiple devices are connected serially, the MADI I/O of each QS 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.
