Drop out problems during last recording - need help
« on: September 24, 2018, 09:21:02 PM »
Does anybody have any idea what this is cause by (see image attach)?
I just use the same gear a month ago and had no problems at all.
Nor ever had with any of this gear with other gear.
Did a 3 hour recording this pass Saturday,
and had this kind of drop out about half through for only 7 minutes.
I was sitting and doing nothing different than I was for the rest of the gig.
I did stand for the last few tunes and no problem there.
As you can see from the screen shot it is totally clean drop out.
No static or noise to speak of.

Equipment Used :  CA CAFS > CA Ugly 2 > Mogami cable gold Neutrik 1/8″ > Sony pcm-m10
All of the above equipment is relatively new and shows no sign of wear.

Check the stereo cables, I would bet one of them is bad.

To me it looks like you have 4 dropouts each one with some sort of artifact. Kinda hard to tell from your screen shot but the spectral color in the dropout (blue) appears to be different from the material that was recorded without any problems.

Whatever it is - it looks consistent. As stated in a previous post, one of the cables or connectors somewhere in your chain could be the culprit.

As an example, I recently ran into a problem with my PCM-M10 and the line input jack and like in your situation it all started one day out of the clear blue sky.

Using several sets of mics and caps > battery box > line in - I was getting distortion and dropouts. When I switched to using the mic input with the same chain of mics and bbox, everything was fine. My M10 is about 5 years old but I only get to use it around 10 times a year (not too many shows here on Maui).

As I was researching various possibilities of why this was happening, I came across an article or post somewhere that said the metal that some companies use in their internal jacks can get "stretched" after repeated insertion and removal of mic plugs, etc. leading to performance issues.

Yes I did, and it was a brand new Samsung card first time used.
Along with brand new batteries for both the deck and pre-amp.

The weird thing is that there is no distortion noise of any kind around the drop outs, none.
Absolute silence, clean as can be.

Even when I was standing up and down at the end of the gig everything was normal, no drop out..
Or when I walk out of the theatre and finally walk to my car and turn it off correctly.
It was only in that one area of the recording for 7 minutes.
The rest of the recording is fine, no drop outs or distortion of any kind.

Are you 100% sure it's a Samsung & not a bootleg?


Not like it would matter, I had a Sound Devices SD card fail in the field a couple weeks ago! (I lucked out, it only cost me a soundcheck that I can't post anyhow)

Got it on Amazon from Amazon, no third party involve. Fairly sure it is legit.
