RadoStefanov Posted February 7, 2014 Author Report Share Posted February 7, 2014 To get back on the subject , DPA sent mics to be tested on the field and I am getting one to test with zaxcom trx900la next week. Will report back sometimes next week. Quote Link to comment Share on other sites More sharing options...

studiomprd Posted February 8, 2014 Report Share Posted February 8, 2014 I said: " the business they do with us is a very tiny part of their marketplace " and I'll stick with that. probably that is not so important in customer service, but what might be making a difference are cultural and language differences in trying to deal with them...

S Harber Posted February 11, 2014 Report Share Posted February 11, 2014 What I'm wondering is why Zaxcom has stuck to using the 3V dc bias when the rest of the world seems to be using a different and more commonly usable bias voltage scheme. So now everyone who uses the Zax wires has to buy an even more obscure version of mics that are somewhat obscure to begin with. And I say this as a DPA lav devotee. Is there no way for the Zaxcom wireless to output a voltage other what they presently do? That would seem to resolve much of the issue that warranted 182 posts and all the consternation so far. This is probably something that is beyond a firmware solution on existing units but Zaxcom may want to look at this for future compatibility. Maybe a software selected bias voltage selection in the future? Scott Quote Link to comment Share on other sites More sharing options...

glenn Posted February 11, 2014 Report Share Posted February 11, 2014 Since Sanken, DPA and Countryman all work at 3.3V it was decided to save the battery power to make the unit run longer rather than waist power making 5.0V. This was what we did 12 years ago and it may not be necessary for us today but thats where we are. Glenn Quote Link to comment Share on other sites More sharing options...
Jeff Wexler Posted February 11, 2014 Report Share Posted February 11, 2014 "Is there no way for the Zaxcom wireless to output a voltage other what they presently do? That would seem to resolve much of the issue that warranted 182 posts and all the consternation so far." I don't think a change in the bias voltage (thus making other DPA models available to use) would have made any difference in this current problem that has prompted the 182 posts you mention. DPA has stated that the 4063 (low voltage model Zaxcom users use) is no different in performance or specification to the other models that use the higher voltage bias (5 volts). Zaxcom users would not have discovered these other models have the same problem (a change in manufacturing) because we don't use the models with the 5v bias. DPAs have been great with Zaxcom transmitters from the very beginning. When Sanken made the necessary changes (which benefitted everyone, not just Zaxcom users) and came out with the COS-11-D, that made the most popular lav (though not my favorite) work perfectly. As Glenn has pointed out, Countryman (B6, and others) have also worked without any problems, as well as Voice Technologies, Sennheiser, Rode, etc. There has not been any shortage of microphones available. The pisser is that the mic we all love just suddenly stopped working properly. That said, I think DPA has finally discovered the problem and it has been corrected.

Doug Beatty Posted February 13, 2014 Report Share Posted February 13, 2014 Back on topic, I just picked up a unit with the DAD adapter to field test with a TRX900LANC on Friday. A big thanks goes to Ryan at Trew for coordinating with DPA. Quote Link to comment Share on other sites More sharing options...
RadoStefanov Posted February 21, 2014 Author Report Share Posted February 21, 2014 After a few days working with the 4063 that DPA sent to be tested I have not experienced any RF issues. The mic has the DAD adapter. I have only tested with the new XR modulation. If somebody is interesting in the old modulation rf performance let me know.

Jeff Wexler Posted February 21, 2014 Report Share Posted February 21, 2014 I have tested the new DPAs that I have (though I haven't used them yet on the job --- first opportunity is tomorrow) and they seem to be fine --- as immune to any spurious RF as the original DPAs. What a relief! Quote Link to comment Share on other sites More sharing options...
Ryan Coomer Posted February 25, 2014 Report Share Posted February 25, 2014 UPDATE: I just received an email from Mikkel Nymand, the product manager at DPA. After thorough testing, in the lab and in the field, they have implemented some component and production changes to the 4063. This issue is officially solved for new mics.

RScottATL Posted February 25, 2014 Report Share Posted February 25, 2014 Awesome to hear. I'm strongly considering the Zaxcom units for bag work. Glad to know the top end DPA lavs are good to go. Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted February 25, 2014 Report Share Posted February 25, 2014 What's the availability of the new units? Short of a round of RF tests, is there a way to identify if we have the new ones? Quote Link to comment Share on other sites More sharing options...

Mark Orusa Posted February 26, 2014 Report Share Posted February 26, 2014 I've been watching this thread since it started. I have three 4063 that I use with my Zaxcom TRX900LA transmitters. When I first started using them I would occasionally hear some noise, particularly when the cable was wrapped near the tx. I contacted Zaxcom and was told to use the 2k filter. That has mostly eliminated the noise, but it isn't a solution, just a work-around. I sometimes hear noise of the high-noise-floor-type and wonder if this is due to the noise problem that started this thread. It makes me question my mics. Is there a way to know if my mics are indeed affected by this issue? Is there a particular path to getting replacements? I know I can contact DPA, but will the person I reach have a clue as to what I'm talking about? My dealer for the mics was Pro Sound, but I hesitate to contact them because they couldn't even wire them properly for Zaxcom tx - I had to modify all of them after I received them. I would love to have bought them at Trew Audio, my usual dealer, but they weren't selling them at the time I made my purchase (Nashville office any way). Trew has always provided me with great service and it's no surprise to see them taking the lead in tracking down the problem with these mics. Mark O.

Wandering Ear Posted February 26, 2014 Report Share Posted February 26, 2014 Mark, if you are hearing the interference, your mics are affected. You should call pro sound and ask them to take care of it. They are aware of the issue, i have been working with them to take care of my dpa.

Glenn Glen, Not sure if I'm reading between the lines but does this mean that you are considering a move to 5v? I'm only asking as I'm thinking of moving to zax radios and at the moment this means having to buy all new dpa's even though I have lots of 4060's from my current system, just because of the difference in voltage....

Matthias Richter Posted February 26, 2014 Report Share Posted February 26, 2014 Mark, if you are hearing the interference, your mics are affected. Thats a bit of a stretch I think. I have bought my 4063 years ago and there was some RFI all the time which the 2k notch minimized. It was a very small amount and hardly audible (only when using the 4063 as plants and using more gain on the TRX). I have not been listening to the latest (faulty) version but from this thread I would expect some RFI which made the 4063 completely useless.
