Register/Repair XDS Wireless
by billshoup on 2011-06-24 13:26:00

Hello,

I am having a very intermittent problem with my XDS wireless.  In the process of investigating how I might be able to get this repaired, I've been asked to register it, however I assume that the serial numbers are pre-Line 6.  The serial number for the XDR1 is 9011195, and the serial number for the XDT1 is 9017154.  Under the FAQ's it says I should be able to ask you to register those serial numbers for me.  I would love to describe the problem I am having if any one is interested.  It is very difficult to reproduce (unless I am on a gig of course, when it ALWAYS happens).  :-)

Hey billshoup,

If the problem you are having is related to drop outs please reference the link below for information on troubleshooting drop outs:

http://line6.com/community/docs/DOC-2217

As far as registering the product is concerned, I was unable to register the serial numbers you have provided.

If your issue does not pertain to drop outs, please elaborate about the trouble you are experiencing.

Hi Don,

Thanks so much for your response.  In regard to registration/serial number, I purchased the wireless new from Musician's Friend on 5/21/2009.  Line 6 is not printed on the unit at all, but rather it says X2.  My understanding was I could still get it registered.  I only want to get it registered in the hope of getting it repaired.

Now, to describe the problem; No it isn't dropouts.  And it is very intermittent.  Normally I use it at least 30 minutes (sometimes much longer) before the problem happens.  When the problem happens, the sound simply changes - the low end becomes quite thin, and there is a very noticeable modulation in the low end, and probably a bit of a buzz.  The tone is quite unusable when this happens.  The poor tone will continue until I either switch channels or toggle the power off and on, on the transmitter.  It seems that once the problem occurs, it happens more often from then on for the rest of the night, perhaps once every 20 minutes or so, but that varies greatly

This has happened in many venues both inside and outside, with two different amplifiers.  It's happened with the receiver sitting on my amp as well as next to my pedals.  I'm using the Line 6 DC-1G power supply and have tried new batteries in the transmitter when this happens, and it continues to be a problem.  I wear the transmitter on my strap, and it happens when I'm very close to the receiver (like within 6 feet).  The group I play with uses no other wireless gear.  I never have a cell phone close to me (to my knowledge) when it happens.  I've always used the wireless with the same strat.  I've tried to get it to happen with my Martin at home with no luck, but I don't believe I've ever got it to happen at home with my strat either - as I said, it can take a long time before it happens the first time.  The only thing I can think of that is unique, is that I have a Graphtech Ghost system in my strat (midi and acoustic pcb's) and looking back, it's possible that this issue never happened before I had the Ghost installed, but I'm not at all sure about that.  I'd be happy to answer any other questions about the problem or anything else about our band environment that might be consistent from one gig to the next that may be connected to this issue.  As I said, I'd like to send it in for repair, but am concerned that you may not be able to reproduce the problem.  Thanks so much for your help!

Bill

Don't know if the Ghost is an issue.  Generally if an instrument will work sucessfully with a cable it will work with our wireless.  Being that you don't have an issue using a different instrument you'll need to rule out the strat itself as the problem.  How is the ghost wired along with the strat's pickups?  What sums them?  Any preamps or battery operated anything in the guitar?  Are you using our factory input cable?

For a cell phone to be an issue they would likely need to be inches apart so that's unlikely anyway.

Hi dboomer,

I use the strat very often with a cable (all the time in the studio, rehearsals and solo gigs) and have never had an issue except when the battery has gotten low (1 time).  So, yes, the Ghost system uses a battery, but the battery lasts a good 6 months for my use, and I change it more often than that.  So if you are wondering whether a weak battery in the strat is the issue, I am sure that I've had the issue more than once when the strat had a new battery in it. Regarding the Ghost jack configuration, the MIDI signal is routed to a 13 pin jack that I'm never using when I have the wireless issue.  The 1/4" jack is wired so that if you use a mono plug both the mag pickups and the piezo (acoustic) signal go down the cable summed.  If a stereo 1/4" plug is used, the two signals (mag versus piezo) are split off.  Since the Ghost install, the mag pickups won't work without the battery, so somehow both signals must be going through the Ghost's "acoustiphonic" preamp.  Yes, I'm using the factory input cable that came with the transmitter.  I doubt that it matters, but it is extremely rare that I use the piezo in situations where I'm using the wireless, and the problem has always occured when I'm using the mag pickups only (probably because I'm using them 99% of the time with the wireless).  There is a 3 position switch for Mag/Piezo/Both that I (almost) always have in the Mag position, and a second Midi/Pickups/Both switch that I always have in the Pickups postion when the problem occurs.

Let me be clear that although I haven't had the issue with my Martin, I have only done brief testing with the Martin.  I never use the wireless with my Martin at a performance.  I can spend more time trying it with the Martin to see if I can get it to happen with that guitar.  Perhaps what I should do is try to get it to happen with the strat, and when it does unplug it from the strat and plug it into the Martin to see if the problem continues?

I will say this, I replaced the power supply for the receiver a while back hoping that might have been the issue.  After that, I recorded a loop on a Jazzman looper and let the thing run for a couple of hours and I didn't catch the wireless having a problem.  Of course it could have had the problem and come out of it, without me hearing it, as I didn't babysit it the whole time.  My point though is, in that case the wireless was connected to the Jamman rather than the strat, so possibly the strat does have something to do with it (as much as I hope it doesn't).

My concern about summing is that passive summing may be loading one of your pickups.  Do you a have access to a different electric guitar so you could rule out your guitar as the problem?



Re: RE: Register/Repair XDS Wireless
by billshoup on 2011-06-30 07:31:36

Yes, I have a couple of other guitars.  I think maybe what I'll try to do is see if I can find a consistent way to make the problem happen in the studio with the strat, and if so, try that with a different guitar.  Sound reasonable?  This could take some time as the problem takes quite some time to happen.

If your theory is correct, since when using a stereo plug the signals aren't summed, is it feasible that if I used a stereo Y adapter and plugged the wireless into the adapter so the wireless only received the mag pickup signal, that the problem might go away?  Further, if I replaced the mono plug on the input cable with a stereo plug that was wired correctly, it would have the same effect as the Y cable and also possibly fix the problem.  Or am I misunderstanding your theory?  Also, it seems having the Mag/Piezo/Both toggle switch in the Mag position would have the same effect, so I probably am misunderstanding.

I suggest just trying a different guitar to investigate further. You should just need a mono input cable to send your guitar signal (whether thats piezo or mags) into the transmitter.

I spent a couple hours in the studio with the SAME guitar today and could not get the problem to occur during that time.  Apparently it won't do it unless I'm in front of a crowd!  :-)  I don't think it will do me any good to try to use a different guitar until I can figure out how to reproduce the problem with the same guitar.



Re: RE: Register/Repair XDS Wireless
by dboomer on 2011-07-01 13:57:16

Figures

Let me check ... you ARE going into the transmitter with a standard T/S 1/4" cable and not a TRS cable, correct?



Re: RE: Register/Repair XDS Wireless
by billshoup on 2011-07-01 15:03:37

Yes, aren't intermittent problems wonderful?  They'll never happen when you want them to.

Yes, I'm using the standard, factory, mono, TS input cable that came with the transmitter.

Had perfect tone today right up to when the transmitter battery died.  Argh!  :-)

Here's another question, which just occurred to me; I have a video panel that I have mounted to a music stand that I use for electronic chord sheets and lyrics (I know, I'm getting old) with the band that I use the wireless with.  It's actually an electronic photo frame what I wired a footswitch into to advance from one song to the next.  Any idea whether something like that may cause interference?  The thing that gets me about this issue is that once it happens, I can't get it to go away (by moving around, changing settings on the guitar, toggling power on the amp, etc) until I either power down the transmitter or switch channels, so interference from something like that the video panel seems unlikely (to an uneducated guy like me anyway).  Plus when I'm at my mic, I'm a consistent distance from it all night.



RE: Register/Repair XDS Wireless

Hey billshoup,

I do not think the electronic photo frame is contributing to the interference you are experiencing. Please continue to try and reproduce the problem using another guitar to help confirm if the issue is directly related to the strat or not.

Thank you.

Hi Don,

I decided to start trying to use the wireless in the studio all the time to try to see if I could get the problem to happen.  This morning I was using the strat for over an hour and the issue finally happened.  I un-plugged the transmitter from the strat, plugged it back in and it still had the issue.  I plugged the transmitter into another guitar with passive pickups and the problem continued.  Previously I found that either switching channels on the wireless or toggling the power on the transmitter cleared the problem.  Today I decided to find out if toggling the power on the receiver also cleared the problem.  It does.  I know this is probably not the exact trouble-shooting you are after, but I thought I'd share what I found.  I will keep trying.

Thank you!

Hey billshoup,

Thank you for posting your results. Glad to see that powering off the unit and powering it on alleviates the issue, although I'd like to see if dboomer's can shed some light onto your most recent findings. Keep letting us know your results.

Thank you.

Had the problem again in the studio.  Of course it happened to be while I was on the strat, as that's what I'm working with right now.  I recorded what it sounds like direct into my recording interface (the mp3 is attached).  I then plugged it into my Martin and it the problem was continuing so I was going to record a little of that as well, when the problem cleared up on it's own.  That's the first time that's it's ever cleared up without me switching channels or toggling power on the transmitter or receiver, but the vast majority of the time I've had the problem has been when I've been performing, so I've wanted to correct the problem as soon as possible.  Hopefully I can get it to happen with another guitar soon.



Re: RE: Register/Repair XDS Wireless

Can you possible send me a wav or aif file.  MP3's are processed and are worthless for diagnosing problems.  Send it to dboomer@line6.com.



Re: RE: Register/Repair XDS Wireless
by billshoup on 2011-07-11 15:00:46

Ok dboomer, I sent you the wav file.  By the way, I had the problem again today in the studio - sorry it was still with the strat.  I decided to force myself to keep playing the guitar to see if the wireless would eventually come out it without me toggling power or switching channels.  It seemed forever (because of the terrible sound), but was probably around 5 minutes (although I didn't time it) and the problem went away as suddenly as it appeared.  Just another bit of infomation just in case it's helpful.

After looking at the file I'm pretty sure you have a hardware issue with the receiver.  Please contact our service dept to get it corrected (see "contact us" at bottom of page)

I was EXTREMELY disappointed to receive my XDS95 wireless back today with the resolution of “Tested 3 different times for 10 min each – Could not reproduce problem” by technician PYagubyan (Repair #97688, RMA#0060000059, Serial# 9017154/9011195). Any kind of glance at the information I provided would have made it extremely clear that this problem has never ever occurred within 10 minutes of use.  Don Boomer asked for a clip of the problem which I provided him (and which I clearly made you aware of).  Don stated both in the forum and in an email;

“After analyzing the file it appears that you have some hardware failure likely in an output audio stage and not a problem with the radio itself.  It's likely an op-amp that is close to completely failing.  You should contact our service department to get it corrected.” 

I would have hoped that you would have followed up with Don’s diagnosis rather than throwing up your hands after 3 ten minute testing sessions and sending it back to me unrepaired. Can I PAY you to do the repair Don recommends?  You can otherwise be sure you’ve lost a customer forever and that I will recommend to everyone I know not to purchase Line 6 products, as you may have a good sounding warrantee, but the truth is unless you have a problem that can be reproduced within ten minutes of testing, it won’t get fixed.  I’m very sorry for being so bitter, but after fighting with this problem for the last several months and finally being very hopeful it would get resolved I’m VERY disappointed.
