Hi,

I have 2 Raydat cards along with some other RME equipment and think its great but I'm running into an issue. I will give you a very quick run down of what we have so you can get an understanding.

- SoundCraft 323XD Mixing Desk that goes into the Mac via AES and provides Mic inputs / Guitar inputs and External Midi Instruments.
- Mac Pro running 1 Raydat card with Wordclock expansion (This contains all the VST's / Vocal recording / Guitar etc etc) goes out on AES to Yamaha D24
- Yamaha D24 is used for quick recording but also passes out to our Adam and JBL monitors to a Mackie Big Knob.
- We also have an Alesis HD24 linked up via Adat into that Raydat and also a behringer convertor linked into the Raydat via adat aswell (this isn't really used in important circumstances)

The chain for the word clock goes:

MAC (Raydat) out 1 > Soundcraft > Behringer > Terminated
MAC (Raydat) out 2 > Yamaha D24 > Alesis HD24 > Terminated

Now it is all linked up using the BNC T-Connectors and the terminated using BNC plugs.

The issue I am getting is that the sounds sound muddy in the low end. One minute it can sound great then gradually over time you can't mix. Is this word clock related? We have tried alot of things like removing as much as we can between the Raydat and the Speakers but it still sounds muddy.

Do you think it could be the fact that the Yamaha is running off the other word clock in the raydat rather than being in the chain?
How good is the Raydat's word clock card?
Would it be beneficial to get a Apogee Big Ben? If so why do you think this (from personal point of view)

Hope you can help
Many Thanks
Joe
