A32 inputs and outputs
22
When using sample rates higher than 48kHz, channels have to be
bundled to transport that higher data rate. As a result, the maximum
amount of usable channels is reduced according to the following chart:
The original MADI standard utilized a maximum channel count of 56
channels instead of 64 channels (numbers in brackets). This lower
channel count allows the sample rate to vary by +/- 10%. Nowadays
the variable sample rate is not commonly used anymore, in favor of
having more usable channels.
In SMUX/4 Mode both MADI connections (optical and coax) will be
used together to overcome the channel limitation of the MADI
standard and transfer all 32 analog inputs and outputs at up to 192kHz.
In this case the first 16 channels are transferred using the optical port
and the remaining 16 channels via the coax port.
The A32 detects automatically if 64 or 56 channels are received. The
number of channels it outputs can be set by using the MADI short
frame switch.
