We have two XD-V75L sets we purchased last year to record the audio for recorded video podcasts. We've done about 6 podcasts with them, but we are really unhappy with the results we are getting. Maybe someone can offer a suggestion...what are we missing? The signal from the receivers are fed through a mixer and then into a digital audio recorder. I have gone through every setting on the transmitters and receivers, but no matter what configuration I select, I get a very weak, tinny sound, and the mics are super sensitive to the slightest change of head angle or the loudness of the person speaking. I have also tried bypassing the mixer and going directly into the recorder. I have switched between using the receivers' balanced and unbalanced outputs. No difference. The lapel mics are placed at about the center of the breastbone. I get all kinds of plosives. I get massive distortion if the speaker tilts his head down ever so slightly, and they become barely audible if the head is tilted left or right by more than an inch. If I don't have the receivers' dynamic filter set to "Talk", I get all kinds of ambient hissing and humming noise...noise that the human ear cannot hear in the room, but the mics pick it up. I am about ready to give up on these wireless systems. These replaced a couple of less expensive Shure sets that we bought at least 10 years ago. We expected an improvement in the audio quality, but we are experiencing the opposite. We prefer using lavalier mics for aesthetics, but will switch to Shure SM7Bs if we cannot resolve these issues. If anyone has any ideas for something we may not have tried, I'd really appreciate it. Thanks, Rene

Are you saying that you can replace the lav mic on the Line 6 transmitter with these Shure models? I've been struggling to get a decent audio recording quality and level from our Line 6 XD-V75L, regardless of settings. I went through the SPF-1 to SPF-6 options on the transmitter, but could not hear a difference between them. Connecting the receiver output to a Zoom H4N recorder produces a very weak-level audio recording. I have to use the "Talk" setting in the receiver's Dynamic Filter or I get all kinds of noise. I thought the Line 6 is supposed to be state of the art, but our 10-year-old Shure wireless lav sets produced much better results. I'm thinking there has to be something I'm missing.

I tried both XLR and TR cable connections between the receiver and the mixer, or directly into the Zoom H4N recorder, and there was no difference in the signal strength. I have the H4N's record level at 70% and it results in a very weak, low volume recording. This is reflected by the record level meters too. This tells me I am getting a very weak output level from the receiver. I've not been able to figure out how to get a stronger signal. I don't want to increase the record level on the H4N any higher, or I'll get more noise. I'd really love to solve this. Does it matter if the cable is TR or TRS? I am using TR (mono) cables.

I started reading this thread because I'm having similar issues. In my case, I am recording people speaking for a video podcast. I am using two XD-V75L units with lavalier mics. These are fed into a mixer and the mixer's output is fed to a Zoom H4N digital audio recorder. I position the mics at about the middle of the person's breastbone. I found that with the dynamic filter adjustment set to "off" or "normal", the recording will have a lot of ambient noise, even though you cannot hear this noise with your ears. We turned off the room's HVAC but it did not help. I don't know where that noise is coming from. It is a steady hiss. If I set the dynamic filter to "Talk" it filters out that noise. But then the mic is extremely sensitive to variations in the person's speaking voice and angle of their head. If they turn slightly to one side, they get too quiet. If they look down, so their mounts are a bit closer to (and pointing at) the mic, they are loud to the point of distortion. I also get a lot of plosives. I get no reading on the receiver's audio signal meter, but the recorder does show a decent recording level. But even though it looks like I'm getting a good signal, the recording is very weak. I noticed one of the comments above about the difference between the XLR and TRS outputs of the receiver. I will experiment with that, but if anyone has any other suggestions, I'd appreciate it.
