Pau,
the system i need to build should have 8 AES inputs
and 24 AES outputs.
For that, i see two basic approaches 1) using two RME AES-32 (*) cards
in world-clock synch and 2) using a RME hammerfall with 24 ADAT
input/outputs and then several 8ch ADAT<->AES converters such as the
Aphex 144 (+), which costs about 400€ each 8ch unit.
3) a MADI interface and any
MADI-to-ADAT converter you want
Right. But the MADI-to-AES alone (the ADI-6432)
costs about 2800€. Far
beyond 1) and 2).
Well, you get what you pay for. Much less hassle, only one cable to
control clock, data and control information - up to several 100 meters etc.
Think of the setup and maintenance costs. This is the plug-in-and-forget
solution.
The driver can
start the buffers synchronously, so you have
sample-synchronous output. To have jack working with multiple cards, you
can either use alsa magic to combine the cards, or use alsa_out (with
disabled resampling).
Will try that with a couple of hammerfall 9632 we have in
the lab before
buying the (two) AES-32.
Any recommended documentation or advice?
The RME cards are easy to set up: Just connect the internal sync port
using the cable that came with the cards and select "Internal" as sync
source on the slave card.
