MADI connectivity solutions;

Soundcraft recommended solutions for MADI connectivity.

Hello,
I'm having a lot of problems trying to get madi to work correctly. I have a si expression 3 (slave) and a si performer 2 going into a mini stage box. I've tried just about everything i can see signal on both boards on the right channel but have absolutely no control on the master board. the trim on the slave board does not seem to be working either. Cant seem to get sound craft technical support on the phone for the life of me. Any help would be greatly appreciated!
thanks!

That has not been stated by Soundcraft, and the diagram came from Soundcraft.

Getting mixed messages from Soundcraft.

My setup is just the FOH board and Stagebox 32. I got a 150' cable that seems to match the specs you show above, but I've been getting clicks similar to word clock issues. I messaged Elliot from SC through Facebook, and this is an excerpt of his response to me:

Quote
Our MADI (as were are the only company that has MADI over cat 5) needs a good quality of sheilded cable to achieve the maximum lengths without dropouts. We sell our own cable which is properly tested to 120 metres (not sure of that in feet!) with no problems, however we also recommended KLOTZ RC5SB cable which is good over 120 metres and is readily available.

I've been trying to find a F/UTP (foil outer shield) Cat 5e cable with solid core but having a hard time locating any in North America, let alone Canada.

BTW, their own cable sells for $1275/100m (328') roll on fullcompass.com. No, thank you.

I don't work for Soundcraft, but this is based on my experiences touring with a Vi6 for a number of years (since ver 1).

The clicks indicate that the console and the stage box are not properly syncing to each other. It is caused by the cable having a capacitance that falls outside the acceptable tolerance for the Madi cards.

If you are in Canada, try SF Marketing in Montreal. We used their (Digiflex tactical cat5 if I recall correctly) sheilded cat5 cable for a 300ft Vi6 snake. I can't recall if it was solid core.
What we found with the Vi6 is that the Madi over cat5 is very picky about the cable. Certain brands work and others cause the clicking you are hearing.
If there is a sound company near you try a length of whatever they are using and see if it works.

Thanks for the info. The Digiflex is shielded, but has a stranded core. Although it is working for you, I think I'll probably get this one (http://www.sweetwater.com/store/detail/EtherShld200) from Sweetwater, as suggested to me by Tim McCulloch in a different thread.

I've been using these with no issues in the 9 months I've been using  it w/a Soundcraft Performer and 32 x 8 mini stagebox

I am not familiar with the console, but I am not aware of any wordclock system using CAT5 cable, usually it is BNC or XLR.

Michael, my question is about word clock, not the madi connections.

Mac, in this case were talking a typical BNC wordclock.  I've just never had a reason to run that type of signal very far.  The soundcraft diagram shows FOH and Monitor consoles tied together.  My understanding is that there would be an awful lot of attenuation on say a 200' run.  Perhaps you've had similar requirements with other digital equipment?

This is really just hypothetical for my anyway.  I prefer to use a good old transformer split rather then sharing mic pre's between two consoles and messing with digital trim controls etc.
