Digital Interfaces
(+/-10%). Hence a signal with 53kHz still could be converted
(48kHz +10%). Nowadays most people don't need this
variation feature anymore and instead prefer to use all 64
channels.
If the A16 MK-II recognises only 56 channels at the
MADI input, the outputs will also be reduced to 56
channels. This function allows to use older devices
not capable to handle 64 channels.
MADI SMUX Modes
In case of frequencies higher than 48kHz, SMUX is used for
transmission. This means, that two (or four) channels will be
combined into one channel. For example, in case of 192kHz, a
48kHz MADI data stream (frame) will be generated. However,
four channels will be combined in order to achieve the higher
data volume. Since this 48kHz data stream can't be
differentiated from a “real” 48kHz signal, you can select it
manually by pressing the
SAMPLE RATE
button.
The frequencies 88.2kHz and 96kHz are a special case, since
there are two choices: Either SMUX can be used (two channels
combined each in a 44.1kHz or 48kHz data stream) or the
frequency is used directly, i.e. using an 88.2kHz (or 96kHz)
data stream. Both methods will have the same result. You can
adjust the desired mode in the main menu selecting the item
SMUX (48k frame or 96k frame).
Please note that all devices connected to the MADI cable need
to have the same frame size, as otherwise the signal won't be
recognised.
