Sujet Comment utiliser plusieurs Fireface 800 ?

21. Using more than one Fireface
OS X supports the usage of more than one audio device within an audio software. This is done
via the Core Audio function Aggregate Devices, which allows to combine several devices into
one.
The current driver supports up to three Fireface 400 or 800. All units have to be in sync, i.e.
have to receive valid sync information (either via word clock or by using AutoSync and feeding
synchronized signals).
• If one of the Firefaces is set to clock mode Master, all others have to be set to clock mode
Slave, and have to be synced from the master, for example by feeding word clock. The
clock modes of all units have to be set up correctly in the Fireface Settings dialog.
• If all units are fed with a synchronous clock, i.e. all units show Sync in their Settings dialog,
all channels can be used at once.
When using more than one Fireface 400/800 the FireWire bus might get overloaded. To prevent
this connect all units to different busses.
Note: TotalMix is part of the hardware of each Fireface. Up to three mixers are available, but
these are separated and can't interchange data. Therefore a global mixer for all units is not
possible.
