My G50 is still at Thomann, Line6 repair center still telling them that it is OK. In the meantime I bought an XD-V75. Today I installed it in the rehearsal room and started its "channel scan" function, kept my eyes on it for about 2 hours. I wasn't using it, just left it to display the scan results. Here's a screenshot about my "local conditions":

I got the G50 back. I wrote it many times that my unit is one of the very first ones, so it's probably with FW 1.02 or less. In the FW upgrade procedure there's not a word that they can not be upgraded with V75 but I found a reply from you to someone that the units with FW less than 1.02 cannot be upgraded with Monkey and V75. Now what, how can I test these 2 systems since I cannot mix RF1 with RF2?

Later edit: I updated the FW in the G50 receiver but I had no luck with the transmitter, I cannot make it to go into "loader mode". You told me several times that I will be able to upgrade it with a v75. OK, I bought a v75. Can you tell me how to do what you promised I would be able to do?

I am just suprised the receiver was made to be upgradable by user and the transmitter not...

Today during the rehearsal I tested the G50 receiver with the TBP12G and than with the v75 transmitter. XD-v75 transmitter was used in RF2 mode with the updated G50 receiver. I saw something I never saw before, the audio LED on the receiver was going red from time to time. I never had this before. With the TBP12G transmitter in RF1 I had no clipping issue. I had no dropouts today...

The other days I used the XD-v75 system, audio signal got into red a very few times (3~4). No dropouts.

I kept telling you my G50 is one of the first ones and you kept telling me I will be able to update it with v75. Now you're backing off? I saw TBP06 can be upgraded via cable. As I recall, the G30 system came up earlier than G50. So... TBP06 can be upgraded but TBP12 not? Isn't there a way to upgrade TBP12 with cable just like the TBP06. I have TA4F and stereo jack at hand, I can make the cable, just need the connection pinout. I did try however 1->GND, 3->TIP, 2->Ring and  1->GND, 3->TIP, 4->Ring combinations, didn't work.

BTW, if you have told me that I could never update my TBP12G with v75, I would have told Thomann to upgrade it while it was there. Now, if I cannot make that with v75, I have to pay the postage to and back from Thomann. Your misinformation will cost me extra 60EUR (77.69USD) and extra 2-3 weeks. Should I thank you?

Also, I found a problem with the transmitter. I don't know if it was "THE" problem, but it could have been the source of the dropouts. I made some pictures, I will upload it. I just can't believe the "professionals" at the Line6 repair center in Germany missed that! (Do you pay them peanuts?) At the moment I can't tell more about the problem I found, it might void my warranty. I will upload the pictures when I will see my G50 back to the way as it was in the first 2 years, aka PERFECT.

Are you sure it was after post 92? Check post 106... "Now that you have a V75 you should flash your G50 with the latest firmware and see if that takes care of your problems."

BTW, there's no way I can see on my TBP12G transmitter which FW it has. ...or is it a sign it is lower than 1.03? Is it written somewhere?

Hello from Australia...

I am not from Line 6 and have no affilliation with or loyalty to them. I say this to give you some "background" to my opinions.

My first observation is to say that my opinion of the Australian representatives of Line 6's marvellous range of products was so low that I bought all of my Line 6 equipment from Sweetwater Sound of Fort Wayne, Indiana in the USA and then paid myUs.com to ship them.

(I feel that this opinion is supported by the fact of that distributor having, just now, gone out of business.)

My half century of worldwide audio work (click on my pink avatar at left for more background) has made me believe that such huge variations in worldwide service would seem to be inevitable, ...but I also know how easy it is to miss intermittent faults when gear is tested on the bench as opposed to using it in the "real" world.

My second observation is to say that the main "advantage" of upgrading the firmware in a later TBP12 beltpack would be access to the "RF2" scheme of frequencies, which I find to be much less robust than the trusty old "RF1" that you have in all of your Line 6 stuff.

Not only that, but there is no way to make RF1 and RF 2 work together. So your decision to use the G50 "as it was in the first 2 years" will, in my opinion, definitely give you many more years of reliable service alongside any newer gear also operating on RF1.

You can find a fuller discusion of both frequency schemes here:

As Don has pretty much said, it is indeed very sad that total "future-proofing" when releasing a new product will only be fully available once Line 6 eventually releases their fully functioning, all-singing, all-dancing crystal ball, their FutureScape CB20d.

(The Beta release has been very disappointing.)

All of that aside, I really do share (and sympathise with) the all too understandable annoyance that you feel, but it is my belief that Line 6 do go a lot further in dealing with such issues than most other manufacturers.

A hearty "me too" from Down Under as far as your XT Live experience !

I've also been amazed at the way "specialists" often become so "specialized" that they totally ignore the wider and far more basic picture that is the heart of the problem.

(Far be it from me to say that sometimes the best way of locating the least useful person in the room is to find the one with the highest academic qualifications.)

As for RF2, I can honestly say that it does work really well most of the time, but is only really essential if

1. An extra two channels are required and/or
2. There's a need for the Line 6 operator to allow WiFi/Bluetooth operators the best functionality possible in a given venue. For me, this has only occasionally happened at teleconferences and multimedia events, for which the V75's front-panel diagnostic display has been really great.

Even with RF1, that diagnostic display has been very handy for revealing the existence of "hidden" 2.4GHz radiation (digital A/V distribution, wireless routers, remote control systems, network hubs, microwave systems etc.) that may affect my operating range.

Nevertheless, given that I don't need the extra channels, I find it hard to imagine that RF2 would ever be required in a normal "audience" situation (such as a concert or in a club) and so I hardly ever use it. 

The bad news: ...YOU got the one in ten thousand or so that wasn't within tolerances when it left the robot who assembled it.

The good news: ...if your luck's so amazingly bad as to now ever actually need another repair, I reckon you're a virtual certainty to win any lottery you might subsequently enter !

Congratulations on your upcoming family addition!  Have you already picked out a guitar for him?  I myself was recently promoted from father to grandpa.  It's amazingly wonderful.

I can't speak as to how an outside repair center handled your problem but if you would please use the "contact us" link.  There is a item called "having problems with my repair center" and make a report it will get reviewed by the LIne 6 service people.
