Interesting debate  :)

As a lot of you seem to have experience with the SRX835P. What alternatives did you consider before buying the 835? JBL or other makes.

Yes. This is what I believe. The mobile stage they bring in is 20x40 and also carpeted. The room itself is 75x125 and full wall to wall carpet.

Two points:

1) I believe it was you who brought up using an analog snake to a stage box located at the console. If that was indeed you, and if that practice is to avoid ESD problems that would otherwise be caused by using a problem CAT snake to reach the stage box onstage, I don't get why ESD is not still a problem, because ANY length of wrong CAT in the system will still result in ESD problems IF you are having ESD problems at all.

It has been amply demonstrated that the ESD contact can occur anywhere in the wrong system, including mics and other devices onstage connected via pin 1 to the PA. Moving the stage box to FOH won't change that.

Connecting the analog snake directly to the console and not using AES50 will stop that kind of problem.

If that's not why you were doing that, now readers know that it's not a solution for ESD problems.

2) The snake that you describe as being properly shielded and grounded is behaving exactly as if it is not. You are just a guy on the Internet to me, so I would suggest you double/triple check that all parts of your cable are correctly set up.

Since I am just a guy on the Internet to you, you will do as you please.

A third, semi-related point: There are over a million X32 family consoles out in the world, or at least I heard that a year or two ago. No doubt they are being used in almost every situation imaginable. The fact that there are a small number of reports of intractable problems seems inevitable (maybe your console specifically has a problem?), and the fact that the number is small is proof that the platform is decently robust. Perfectly, no, but decently.

If the surfaces are sitting next to each other, you could do a Copy Audio on the DiGiCo and send to the local MADI I/O for transport over to the DLive.  You would need the SD7 for preamp control, and in reverse, you could send signals back into the SD7 surface via its local MADI for PA/monitor drive.

If you take splits directly off the SD Racks via the Aux MADI ports, the SD7 would have to not need any of the output cards on an entire rack for for you to be able to send to the output cards from the DLive.  On an Optocore ring, you can split output cards on a per card basis, but on MADI it's on a per rack basis.  I don't recall if you can do preamp control for the SD Rack from a DLive though.

If the SD7 is part of the show, you could do via MADI from the DLive to SD7 surface for the outputs from the DLive - direct inputs into a matrix on the SD7 that then drive the PA/monitors.

In short, it's largely possible.  It depends on how your cable runs will be (whether to/from a surface or an SD Rack) and whether or not the SD7 is part of the show.  The question remains about preamp control - I've never tried it from an alternate desk.

Brian,

In that city the sd7 would be part of the show if i use this scenario.....

As far as cable runs, I could do either, surface or mixrack, if I use a mixrack then it might as well be the Dlive's. Use these i/0 s for inputs and monitor sends and at FOH send to PA/subs from the Dlive surface to the sd7 (surface to surface) Madi or analog...

I said no copper before because more and more in refurbished/ upgraded venues, they've done away with the copper mults ....and only use cat5-6/ coax/optical /fibre for interconnects...and although we,re pretty much self contain on tour we do use house PAs....few have many analog i/os available at foh.....or an extra rack.....

Nick,

 this is how i remembered it also , in that instance , i guess madi out from the Dlive could go directly to a "generic "madi in on the sd7 and re assigned to the PA  as they would normally do....it's just treated as a source and not sd rack control?

Then the Dlive would be "master"?

thanks to you both

Ray

You might look at the R3 Spot which has a 13-37 degree zoom.
This makes for a more versatile fixture, though bigger and more expensive.
PM me for pricing.

Not 100% sure on the current state of pre-amp control. But last time I looked into it, control for Digico pre-amps through BNC MADI can only be accomplished with a Digico desk (not sure about fiber, but I suspect it is the same). I believe the protocol uses channels of the MADI stream for communication with pre-amps. If a non-Digico device is connected to that MADI stream those channels won't be available for audio. This is from my hazy memory of experimenting several years ago.

Anyone know proper way to set this up?...without copper...sd7 is house console with various stage racks...Dlive is touring console...could we get all the mics patched thu the digico stage racks. and then sent thru coax madi to the dlive and the dlive outs in reverse to the sd7 madi and in turn to the PA/monitors etc.... how about clocking? which runs which?

If you need a beam fixture. I think the R2X would fit the bill. They come through a lot on tours in a local 1000 cap theatre that has a 37w x 29d stage with a 20' trim and they hold up against bigger, "badder" fixtures well without being "too much" for the room.

We own a bunch of R2 washes and have had zero issues. Obviously a very different fixture, but similar build quality.

I'm curious if a moving wash such as the R2 would be more useful for a theatrical application.

I use one of these which can be set to 'push to talk'  or  'push to mute' (small switch on side of unit) depending on application:

Rolls MM11

(edited to clarify position of switch)


Thanks all for the comments.  The band let me know they just usually leave them open.  Aiming them toward audience may help so that's a good tip. 

Thanks Deb for the switch.  That may work for them in the future.

This is a small bar setup with live drums and bass but keys and guitar are direct.  It will be interesting.

I wonder if anyone has done a study to see if there is any correlation between electricians scores on their qualification exams and their life expectancy?

At least for the Maryland Master Electrician test, there's a time limit with too many questions to spend enough time on each one. For example, the final 6 questions count 5 points each, but each one is a test in itself where you have to determine the size of the feeder transformer powering different building, such as an apartment complex, college dorm, commercial store front, etc. So I can spend maybe 10 minutes on each question max, and you have to show your work. If I was in the business of installing electrical power for apartment buildings (which I have never done, or plan to do) then I would spend a lot more than 10 minutes determining the size of the transformer based on the number of units in the building, number electric ovens, number of electric clothes dryers, air conditioning units, etc... If fact I would probably build an Excel spreadsheet with all the proper formulas and de-rating percentages, then plug in the number of apartment units and appliances to get the final KVA value. It might take me a few hours to build the spreadsheet once and test it, but after that it would be 5 or 10 minutes of plug & chug for each calculation. Plus I find a lot of information via a search on the pdf, which is really quick (and perhaps a little lazy on my part). But the written test requires you to use a physical copy of the book and mark it up with little tabs. That does help a lot, but realistically that not how I work nowadays.
