Consumer
Sets the AES Format bit.
Note: This setting is overridden to Professional in DSD or DXD Projects when DSD is selected as
the output format.
High Sampling Frequency
High Sampling Mode
When ticked, MADI carries high sample rate signals in sample Interleave mode, which routes samples in a different
way and order to the outputs. This mode is only available for sampling rates above 48kHz through the MADI I/O. In
brief the data is interleaved by samples, whereas in normal mode, samples are interleaved per channels. Some
converters need to have this mode enabled to allow the transport of 32 channels at 96kHz in a MADI Frame.
Note: Some converters use alternative nomenclature other than than High Sampling Mode,
Frame Mode has been seen on a variety of converters.
Note:
96kHz with 28 channels working (legacy pattern, as formed by legacy encoder fed by single-chan-
nel double sampling-frequency mode signals per AES3).
Note: 96kHz with 28 channels working (96kHz frame pattern, using 10,4
μs framing, one channel-
zero flag per frame
).
MADI Wordclock I/O at base rate * 2
When ticked MADI Wordclock is expected and output at base rate times two.
Note: High Sampling Mode setting is overridden in DSD or DXD Projects when DSD is selected as
the output format.
MADI Wordclock I/O at base rate * 2 should be un-ticked for DSD
