As I said last week, I think your unit is defective. I am going to ask CS to contact you.

Thanks for the speedy response, John and for easing my curiosity.

Here's hoping a "bench test" reveals more.

HI Ron! no, we haven't been able to try another mixer... the general consensus is that because all our other equipment works fine (including the Audio Technica radio mics) the Line6 mic is just proving to be too much trouble ..

At the end of the day, the device may not be faulty! - but I have to entertain that possibility now, even if its just to rule out a problem with the unit...

hey ho!

Just a quick one, John...

...As Don Boomer asked a while ago: "Have you tried it in a different mixer?" (Such as in a music shop...?)

Here's hoping the (rapidly advancing) New Year brings you nothing but the best.

Hello folks! happy new year! Ive been quiet for a bit whilst we try to try out cables etc.. so heres my report!

We bought two brand new XLR cables one from an electronics store, and one from a music store (was an accident, but thats another story) We have a guy here who works in the tech dept of a local Hospital.. he took the new cables to work to test, and assured us there were no "earth to casing" problems. We brought the cables back to the hall and plugged in - wait for it... same problem. Sigh... I think at the end of the day, there may be a fault with the unit. I'm not sure where the unit goes back to now.. prob Line6 as I don't think the store will accept the return after so much time.. I'll mail Line6 later today...

Thank you all for your enthusiastic help!! I will post again with any progress I have!

"In the finest traditions of the Service", Steve...

...Exactly as I've come to expect from Line 6 !

I am, however, wondering if Line 6's Quality Assurance section actually has any of the cheap and nasty "pin 1 and chassis-wired" cables in its inventory?

Given that I hadn't struck one for years, I was curious enough to "create" one before packing for a Seasonal gig yesterday and ...guess what?

Using it and applying 48v phantom power via the "global" switch on a variety of small mixers yielded textbook earth loop buzzing when it was connected to the output of any of my randomly-selected XD-V70 receivers, ...but only from some of those mixers.

I guess the most revealing analysis was provided by my tiny and "bulletproof" Sound Devices MixPre D, (a portable field mixer with comprehensive facilities) which would not ever yield buzzing from my receivers when just "on its own" being powered by its internal AA batteries.

When, however,

Connected to some mains powered "downstream" systems ...AND
It also had its Sound Devices "universal" mains supply energised and connected to its Hirose "Ext Power" connector,

would yield buzz on applying phantom to my "freshly butchered and dual-earthed" XL cable, (but only with some of those downstream devices) regardless of whether its front-panel "Power Selector" switch had it running from its internal AAs or external power.

Finally, here's hoping Santa is as good to you and yours as he's just been to me...

All the very best (and a hearty "Ho, Ho, Ho !") to all from Down Under.

Hi Guys,

I need to pipe in here. Based on this posting I asked our QA guys to grab a couple of fresh XD-V35 Production units and test them out on various mixers we have around with phantom on and off. We did not use any special cable or hookups but none of them exhibited the buzzing issue. So I suspect the OP may have a defective unit. I suggest contacting the store or customer support and letting them take care of the situation.

I am the Product Managerfor Wireless at Line 6, so tell them Steve sent you.

Thanks and sorry you are having this experience. We should be able to rectify it if you can contact CS.

Happy Holidays!

Steve Devino

Any reputable "brand" should work just fine, as reputable manufacturers and suppliers should all be following the AES, ISO, EN and US standards for the connection of balanced audio.

It's important to remember that these specifications don't just address the wiring from Line 6 receiver outputs, but are intended to eliminate potential connection anomalies from all sorts of connection and/or cable extension situations.

Earlier in this discussion, I supplied two examples from each side of "the pond", but there are many more out there.

Here are those links again, but they link to exactly that, "examples":

I've also two further suggestions for you:

Carefully read this discussion through, "from the top" ...and then
Have a great Festive Break.

so what brand of cable do you recommend using with the Line 6 reciever ?
