Emu XL-7 & MP-7 User's Group

For some reson I always thought that you couldn't slave a clock using it's
digital out connection to another device, the clock is just a digital packet
transmitted as part of the normal one way communications.  This means the XL7
has to be the master, since it has no digital in or word clock in.  So what I am
getting at is after looking at your configuration, I'm thinking you should realy
just used balanced analog into one of your mixers, and use the mixtreme as the
clock master.  There are a few potential things you could do, but trust me it's
not worth it.  The real problem is that your digital inputs on your TMD's don't
have an independant clock sync / converter.  Not a lot you can do about that and
besides a balanced connection will sound just fine.

Andre,
Thanks for the reply.  I was using my PC soundcard (Soundscape
Mixtreme) as clock source for both TMD-1000s via TDIF.  One TMD-1000
is set to SPDIF digital input for the channels used by the XL7.
I tried changing the TMD-1000 so that clock source is coming from the
digital in from the XL7 and then set the Mixtreme so that it was
receiving it's input from the TMD1000 via TDIF.  I connected both
mixers together with SPDIF and set one to slave clock from the other
(normally I have both slaved to the mixtreme via TDIF).  This setup
caused lots of problems.  I got lots of digital input errors on both
mixers and when I record in Cubase I get nothing but noise.  Is there
any way to set the XL7 so that it syncs to SPDIF clock?  Maybe I
should just forget this whole mess and go with analog inputs!!!
