In previous versions, the mixer only generated it's own clock @ 44.1.
I hate AES!

Subject: [Avid-L2] Re: AES/EBU error msg
According to the 01V96 Version 2 manual pdf I downloaded the mixer can do
48K. From the manual:
General Spec
Number of scene memories
99
Sampling Frequency
Internal
44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz
External
Normal rate: 44.1 kHz-10% to 48 kHz+6%
Double rate: 88.2 kHz-10% to 96 kHz+6%
If you are digitally connecting the 01V96 to other equipment, you must
decide which device to use as the wordclock master and which devices to use
as slaves, then set up all the devices accordingly. The 01V96 can be used as
the wordclock master running at either 44.1 kHz, 48 kHz, 88.2 kHz, or 96
kHz, or slaved to an external wordclock source.
Wordclock Connections
To establish wordclock synchronization between the 01V96 and external
devices, you can distribute wordclock signals independently via dedicated
cables, or you can use clock infor- mation derived from digital audio
connections.
The WORD CLOCK IN and OUT connectors transmit and receive wordclock signals
inde- pendently on the 01V96. The following examples show two ways in which
wordclock sig- nals can be distributed and received via the WORD CLOCK IN
and OUT connectors.

a digital source, and it looks like it is trying to slave to AES1/2, where
your Avid is connected to. As soon as your Avid goes into capture mode (or
to record scratch track or audio punch in), it will look to its AES inputs
for sync. If the output of your mixer is routed to the Avid, then there's an
audio clock loop, with the Avid looking for sync from the 01V, which is
trying to slave to the Avid.

from the BB gen into the SPFID input of the 01V. I feed the BB gen into the
Avid. Now they are both referenced to the same source clock.
