20.3 Multichannel Recording
M-16 AD and M-32 AD can be combined freely. Therefore 16, 32, 48, 64 (or multiple thereof)
different audio signals can be recorded by the computer.
When using the HDSPe RayDAT, the converters are connected via ADAT optical with the card.
This setup will allow for up to 32 channels with 2 M-16 AD.
The clocking can be set up in different ways. It is recommended to operate the card in clock
mode Master, with all converters operating as slave.
One M-16 AD. The clock source can be an unused ADAT output of the RayDAT. In case the
Word Clock Module of the RayDAT is present, its word clock signal can serve as clock source
for the converter.
Two M-16 AD. As described above, the first converter might use an unused RayDAT ADAT
output as its clock source. The word output of the first converter has to be connected to the
word input of the second converter, which has to be set to word as clock source. The same
applies if the RayDAT’s WCM is present, so only one word clock line is required from the card
to the converters.
