| Really? It doesn't surprise me at all, especially with the experience I've had dealing with MOTU drivers, etc....
Why would they have 2 clock references? The clocking hub of the MOTU setups is the PCI card. If it's a firewire system, then it's either one clock or the other, and the second unit will slave to it.
If they were only converters I would understand it, but the MOTU systems are integrated with the computer drivers, etc... Therefore it's perfectly logical to me that they don't require multiple word clocks for each interface.
I wouldn't worry about it. Just clock the master MOTU interface to it, and let the slave interface lock to the first one. No big deal. You're still clocking the entire MOTU system from the Antelope I believe.
Even in the case of the Lynx AES16, if you disable Syncrolock, you're still going through the clock chip. Maybe you're bypassing the active phase-locked-loop, but you're still referencing the unit's internal clock, after the external clock. |
