Hello, I found the Beyerdynamic opus 54 works with line6 systems as well, but I'm not shure it's good enough for drummers. I'd like to ask: Could you tell me some headset mics that you know are compatible, for singing? just for haveing better sound quality than with the line6 hadsets. Thanks a lot.

Hi, I think I have the problem somehow solved, or at least more controlled. Sorry I don't focus on the RF1 problem. The only thing I can say is that I have it as well, at least when I use 11 units working at the same time, I don't know if it occurs with just one unit. Swapping to the problems that I had working in RF2 mode, I have to say that they disappeared. Now I'm using line6 and Beyerdynamic mics in each channel, and 11 systems in an almost clean wi-fi environment, performed perfectly. So I think that the theory about high sensitivity mic was ok. I don't know why they produce distortion (kind of artifachs) when used in a lot of systems at the same time, without signal clipping leds in the receiver. I can use this cheap mics with a few systems at the same time with no problem, though. So thank you very much for your advise, and hope this information can be useful for you. Josep.

Hello Steve, I'll try to answer: I don't have any DPA, but the theory could have sense, because I find the distortion much more important when the mic is more sensitive. I found problems in a channel with a thomann mic that disapeared using a lavalier Line6 mic (or even a headset one). More sensitive mic produced more distortion, but the receiver was not clipping and as I said before, using this mics alone was very difficult to make them distort. Always speaking about both modes, not about the RF1 mode distortion. Sorry, during the soundcheck, I meant with few transmitters on. With them all on, the problems occurred as well. I made them shout during the soundcheck till they thought I was crazy. Not so wrong... I power each receiver with its transformer, all together in the same plug. I had them all on during the soundcheck. I'm sorry I'm not focusing my explanations in the RF1 problem wich you are dealing with, but the distortion that I found is much bigger and as I said is not mode dependant. Thank's Steve, I found It could be related with the mics sensitivity as well, that's why I decided to use Line6 mics in every channel. What was puzzling me as well is that the units with Line6 mics didn't perform as well as I was used to. I keep on posting. Josep

I will order more line6 mics, so each system is working with them, and we can discard that it is a mic problem, or not. I tell you how they work and maybe we have more data about this issues. thank's again.

I'm sorry you didn't understand me. The systems work in the gig as well but each one alone, or a few units at the same time. the problems appear when working all at the same time. The distortion that appears in RF1 mode and not in RF2, is this kind of artifacs that Daniel posted. It's not on a sine wave, but I think it is clear with a voice as well. As I said I think it is more present as you increase the number of systems at the same time, because I didn't noticed checking one system alone, but I'll check. Yes, I tried the two modes at the same venue. This doesn't represent a problem for me, because I can work in RF2 mode. The other distortion which is not mode dependent is just distortion, as if the microphone was clipping. ""I'm wondering if something is getting into the mics themselves from the transmitters and that signal is then just being passed through"". Can it happen when a lot of systems working at the same time but not when this unit works alone? I can make the sine wave test, but I just have 5 days for returning this systems wich I can not work with. Now my options are: 1. change the v 55s for v75, hopping I'll have no more this problems. 2. buy more line6 mics and try all the systems with the same mic, and see what happens.... (just in case you tell me the transmission quality is the same in both systems V55s and V75s). or return them because they have some hardware problem. that's why I'm asking your advice, and the differences between the systems. I can not wait for the next gig and having this problems again. Thanks.

Hello, last weekend I've been testing my system again. I have the same problem in RF1 mode as other users kindly posted. The same distortion (digital artifachs...) which is not present in RF2 mode. I've been using different mics including Line 6 headset and lavaliers. It's exactly the same distortion. I think it is more present as more transmitters are working, because in the sound check, it was not present or it was not easily appreciable. This problem disappears in RF2 mode. Apart from that, in any mode, I had the same problem that I found the gig before. A lot of distortion appear when all the 11 v55 systems are working at the same time. Specially with thomann mics which are more sensible, but I'm sure it is not a microphone problem, because when I test it alone, there is no problem at all (I have to make a big effort so that it distorts, and the distortion that appear is not so terrible). The systems with Line6 mics have a worse behaviour as well, the sound is not so clear, it seems compressed and a bit distorted. With all the transmitters off, almost no RF red leds were shinning. The receivers were placed at 2 meters in the side of the stage, with no wall or curtain in between. I've been using 5 systems a lot of occasions and they performed excellent, and started to find problems now with 11 systems. As I understand, it have to be a V55s problem that V75s doesn't have, because otherwise, other friends in this forum would complain as well. Do v55s perform somehow worse when a lot of systems are required at the same time? Thanks a lot. Josep.

So as I understand, there is no reason for working in RF2 mode if you are using 12 systems, because RF1 mode transmission is more reliable. Apart from that. Is it possible to mix V55 and V75s in the same event? up to 14 ch? Thank you very much.

Excuse me for my poor english. I meant to set them up in RF1 mode. As I so in the pilot's guide you can switch the mode in the transmiter. Do you have to do something in the receiver? or it recognises RF1 mode automatically? As long as I use just 12 systems is it better to work in RF1 mode?

I don't think this is hardware issue, because as I said before, I found no problem testing the 10 systems myself at home. No distortion with any mic. The problems were in the gig. Ok thank's, i'll try it again next gig. By the way, is it possible to program v55 systems in RF1 mode? Thanks again.

Hello, definitely I think I'm not talking about the same distortion as Daniel. I've been checking my units thoroughly and I did not recognze it. In fact, I found no problem with none of the microphones I use. I don't understand why I had so many problems in the gig. Then, the microfones with more sensitivity (thomann's ones) used to distort (a lot, like if the transmition was bad). Testing them myself shouting!!, no problem, even with 10 systems running and transmiting some signal wich was playing on a speaker. why I did have this problems? as I understood, with this systems when the transmition is not good, drops happen, but not distortion... Don I leave my email for if my problem is not realted with this forum's. jsala@amanitasound.com. I'd like to know abot 55s vs 75s. Thank's a lot. Josep M.

Thank you very much for answering. I'll try to make myself more clear in red and I'll ask something more: Is the signal transmission better in 75s than in 55s for any reason? Thanks. Josep.

(Josep - were your units definitely in RF2 and not RF1 when you noticed the distortion?) I will check it. I didn't change it and I read they work in RF2 as default.)

Hello, I have some xd-V55 systems, working in RF2 mode. I find a lot of distortion problems as well when the singer sings loud. First I thought it was because of the microphone (thomann one which are impossible to be used, a lot of distortion!), because using the line 6 one a bit far from the mouth, the problem was not so appreciable. But then I found that with the Line6 mics the distortion was still occurring in some singers with louder voice. It is HF distortion. The signal level in the receiver is just 2 or 3 leds as much. I had to end the gig with some lavalier mics (far placed). I've been using now 11 systems. When I used just 5, I didn't realise about this problem, but I can not confirm that it didn't happen because they were used for speech. I thought it could be because of the output signal level (which is no adjustable in the 55), but I see people have this problem with 75's as well, and I really don't think so. I'm afraid as well, it is related with the transmission, there is something that I don't know if it is normal. With all the transmitters off, no red transmission leds on (just 2 or so in random devices). When I switch on some transmitters, the others witch are set in different channels. start to show all the red leds on. There occur some drops during the show as well. I feed every receiver with its pair of antennas. Hope you can give me some advice. Thanks Josep M.
