It is a good idea to read the link that Mark referred to. It could be many different things from RF interference to mechanical issues. Check the nut on the jack on the Sennheiser G3 body pack if they get loose I have heard similar noise. I have had a persons clothing (I think they were wearing silk) cause a noise that was really hard to trace.

Don’t forget proper frequency coordination in the environment. Don’t trust what the manufactures say is a good combination.

I consistently test all of the wireless body pack mics that I use before they are put out for the actors. While wearing headphones I cue up each one and talk into them listening for anything that is not normal. I then hold the pack up in the air with the mic dangling and I run my fingers down the wire. If there is a problem and many times if there is one that is about to develop a problem you will hear it when you do that. While listening I manipulate (wiggle) the antenna and the mic connecter making sure everything is tight on the pack, like the loose nut thing I mentioned. I then talk into the mic again and if all checks out ok it is considered good to go for the show.

Could you be having sweat problems? Also I would never let a person have another wireless device like a phone on them. Have you ever heard what the iPhone handshake issue sounds like? I can’t remember ever having a presenter refuse to let us clip the pack on their belt. This was before ear set mics, we used MKE2 mics on Lectrosonics packs. And we usually real neatly rigged the mics on their clothing.

There was this one presenter who always came wearing a dress and I would hand her the mic and pack and send her off to the bathroom for her to attach it to were it worked for her. And she would come back with the mic sticking out near her neck and I would deal with mic placement. I remember one time after she was done she wanted to get the pack off without having to go back into the bathroom so in the corner of the room I stood with my back to her blocking any ones view and she removed the pack and handed it to me. I remember the pack being very warm. The funniest part was every time she would see me to get wired up it was like she was just remembering she was wearing something that required her to go thru this routine to get mic-ed up.         

I once had to mic up one guy (I am pretty sure he is or was one of the riches men in the world) and he was a handful. He was so hyper and fidgety it was a challenge to get him to stand still enough. I just felt like telling that story.

All sounds very familiar! One CEO was insistant he did not want the head mic with a pop shield saying it distracted him another insisted it must be brown (we obliged). Most women CEO get fussy about you touching their hair! (reason for using single ear units)
Actors are probably a lot more disciplined than delegates which helps keep issues to a minimum,your advice is all good  another thing I also do is monitor the radio receiver racks with no TX units switched on to ensure no one else is on the frequency in nearby hotels or conference rooms anything spurious flashes up from the red mute dispay.
Phones are definately a suspect so will look to clipping the packs to belts only as many do not like being parted from their handsets!

Stop blowing it their ear and they won’t freak out so much.  ;) ;) ;)

Actually I wouldn't be surprised if we were to encounter that someday but it is more likely that they just don’t want anyone too near them and they don’t like to be touched. But usually someone with those kinds of issues aren’t going to be someone that would be getting up in front of a lot of people and talking.

Personal space invasion is actually worth understanding. I too explain what I'm doing and try and make it as fast as possible for the likes of CEOs, often they are more concerned about their presentation so any annoyance or distraction is never welcome however vital it may be! being polite at all times helps diffuse any possible awkward moments and always have fresh breath!  Crew meal garlic overdose the night before is a hazard!

Hi

I use a lot of DPA product and it performs without question however on a  recent conference event I have experienced two puzzling issues which I wondered if anyone else had encountered,the mention of DPA is only to confirm that the systems are good quality not budget which would offer an easy answer to the perceived problems!

2.  Another delegate went up using another same type headest no 4 and this time there was a definite difference in levels as he spoke (like someone was turning the gain up and down!) no popping as with Ps and Bs  it was just an undulating level, the headset appeared to be correcly positioned but when he came off for a minute during a co-presentation we slid the mic boom back another 1 cm  and it seemed to fix the problem. It was in the right position when we got the problem (to the side cheek 1.5cm off skin and 1.5cm back from corner of the lip).

We were running 6 systems and they all performed fine except for these two issues which did not repeat or appear previously.  Usually there is a pattern or an obvious reason why problems occur but I cannot figure what happened so would be interested in hearing from others on the subject.

Useful info

System DPA D:Fine single ear. Senheiser G3s /combiner amps and directional shark fin antennas.  Rx 0db   TX sensitivity -24 ( I know many prefer -30 upwards so maybe a factor on the level problem?) Desk Yamaha running with low compression ratio  3:1 and HA gain at + 24

I did hear somewhere about a person's body chemistry affecting systems or possibly pacemaker /phones.  Most speakers usually keep their phones with them and ask for the belt pack to go in their jacket pocket's rather than on their belts (fast and less intrusive) which was the difference with the women speakers who attached the BP to the back of their dress (no jacket)

Thanks in advance for any input.

Guy

I recently run by your second problem at an event. Did you find any treatment?
