Bizarre audio problem with my FS100

Beware everyone…

This FS-100 has an incredible image…but you cannot get good sound with this camera…it records barely audible beeps to your sound…they don’t follow a pattern…but it renders all recorded audio useless…Sony does not officially recognize this as a defect….though they are taking my FS 100 back…

I really hope they fix this problem with the fs700…

Love love love the image but not being able to record trustable sound is a deal breaker for me…don’t want to always have to record sound separately…

Tried with 2 different fs100s and different mics but always get the beeps…

And many people are having this problem…just google fs100 beep…

This is heartbreaking…

Beware indie film makers…
 
When you say disconnect the hand grip jack...what do you mean exactly?

Like render the hand grip that you use to hold the camera useless?
 
I've been having the same problems...the beeps weren't very loud though, but noticeable. So, I have to send my FS100 back to Sony??
 
Strange, I don't get the problem. I phantom power a Rode NTG-2 or the kit mic and have specifically looked for it. I also use the hand-grip always. I know there was mention of certain cards causing the issue. My cards are all Transcend.
 
I'm still having issues, and still cannot change things (adding inline isolator, using only phantom powered mics) so I am guaranteed of no beeps every time. It seems unpredicatable. I haven't taken the time and expense of sending my cameras (two) back, and just generally make sure I have an external audio backup.

I thought I had the beeps licked with the ME64 by removing the battery and powering externally, the beeps disappeared, but then this week they were back with that mic!
 
I have no issue with the standard mic or an NTG-2. But last weekend I had some electromagnetic interference with strong ultra and super high frequency (UHF/SHF) signals and the standard mic at input 1. Next time I'll test some kind of ferrite beat at the mic line. This may also help against an interference from the SC card or any other high frequency source.
 
So does anyone have an update or fix? Unfortunately, my introduction to this problem was during a really important shoot where it seems I delivered footage that had audible beeps baked in. I used 2 shotgun mics that were not pre-amped. Channel 1 had the beeps, channel 2 seems OK. The handle was never on the camera.

Can anyone offer some advice on how to minimize these beeps in post?

I have to say I'm quite surprised to have read through this whole thread, all the while expecting to come upon some version of a solution, but then coming up empty in the end. Have people giving up looking for a fix? Has Sony owned up to it? Is there a best strategy, and is it by means of the right SD card?
 
I'm still scratching my head.

My channel 2 was/is the biggest beeper. Comes and goes. I avoid battery powered mics on Channel two, and some mics like the ME64 seem to be worse.

Haven't had time to send it in to Sony, and am concerned they will return it saying they couldn't duplicate the problem.

I don't see SD card brand being a factor.
 
1 problem, many guessings, no answer from sony.....I just read the whole thread. One thing I can confirm: battery powered mics into phantom powerable inputs are a high risk for unwanted noise also on panasonic cameras. The audio circuits are reduced to micro-sized, smd mounted boards. No space for wound copper and isolating transformers that are needed for a good quality mic-signal. The cams are supposed to get better, faster cheaper and we pay the price cause the laws of physics aplly. plus my favourite law: good-cheap-fast-pick any two.
 
I'm having the same issue (unfortunately, it affected two shoots). I've run many tests... Initially, all test included XM1 shotgun, a Senn G3 wireless lav, an SD card, the FMU, and no handle attached. I had the beeping sound for all tests... with SanDisk SD, Transcend SD, no SD card, and SD with no FMU (quieter beep without the FMU). Then I added an isolation on the G3 with ISOBLOX. This fixed the beeping but introduced a pretty bad buzz. When I replaced the G3 with a wired shotgun or handheld everything sounded great.

This means no more wireless mics for production?!?! Any fixes yet? Any word from Sony? I can't believe that this can go on unresolved!
 
I had a variation of this problem on my FS700 (i only had beep on my shotgun track using an unpowered Rode NTG-3), and read this whole thread intently. My fix involved buying six types of SDHC cards. i found that three caused beeps, three didn't. Beeping cards were 64gb Lexar Professional 400x Class 10, 32gb Kingston Ultimate 100x Class 6, and 32gb Delkin UHS-I "best" 633x.
The cards that didn't beep were 32gb Lexar Platinum II 100x class 10, and Kingston class 4 cards (both 32gb and 16gb). (all three produced very, very low screeches that corresponded with the memory card light blinking, but they were only audible if you really cranked up the volume, and disappeared under any normal recording.)

It seems to partly be a 'class' issue, with the lower class cards not beeping. it was true that none of the class 4 cards beeped. However a class 10 Lexar did not beep and a class 6 Kindston did.

The clearest theme was that the more expensive the card, the more likely it was to beep. Both cards that didn't beep were around $23 for 32gb. The beeping cards were $48-$91 range for 32gb. The "Professional" Lexar beeped, the cheaper "Platinum" Lexar didn't.
Of course i'm worried that these cheap cards won't hold up over the long haul, and i'll probably just replace them once a year. But for now i've got a functioning FS700 again.

I haven't heard any beeps on my FS700, I was thinking that Sony's moving the channel 2 audio input away from the SD card slot was a plus for minimizing interference. Not so it appears.
 
Well I have never had the problem before but as of yesterday I had the beeps on my fs100. gonna try it today at home without the handle plugged in...
 
That's is what is perplexing, it is hard to pin down a problem when it is not there 100% of the time, good luck.

I wonder if it is the LED lights that are emitting RF interference. Did a quick search and found this: http://prudentrver.typepad.com/leds...-might-emit-radio-frequency-interference.html

I don't think, that this little LED makes these beeps. BTW: If anyone wants to have more information about LED light bulbs RF interference? We made some tests here in germany some years ago with larger LED lights. The short english version is here http://www.youtube.com/watch?v=o8zMhjXcmoA. Tests are starting at about 6:00.
