Brian Liston Posted September 9, 2019 Report Share Posted September 9, 2019 I did a two day job with an Amira a little over a month ago. Suddenly, the camera owner is saying that I fried the audio board on it with my ERX-2. Is this even possible? I mean, even a short to put Timecode over there at full voltage shouldn't fry a board, right? Quote Link to comment Share on other sites More sharing options...

Shastapete Posted September 9, 2019 Report Share Posted September 9, 2019 Was it working on set? A month later is a bit suspect, imagine calling up a producer and saying a transmitter broke a month ago on set and they need to replace it – unless there was an on set incident report or at least a conversation/email that something happened that claim would be denied immediately.

Steve Foy Posted September 10, 2019 Report Share Posted September 10, 2019 Sounds a bit suspect. The only incident I have ever heard of was when a colleague cooked the audio board on an Alexa by inadvertently sending P48 voltage into the headphone jack. He was using one of his Mixer inputs as a return feed from the Alexa and and didn't check that P48 was switched off first. Quote Link to comment Share on other sites More sharing options...
Brian Liston Posted September 10, 2019 Author Report Share Posted September 10, 2019 He says the audio stopped working the day I had the ERX plugged into it, and he sent it in a month later. So, I need to contact Arri I suppose to find out what they said. I would just love to hear a scenario where the ERX could fry a camera. The ERX doesn't even send +48V. And honestly, an ENG camera shouldn't get fried over that. Quote Link to comment Share on other sites More sharing options...
edward chick Posted September 10, 2019 Report Share Posted September 10, 2019 I’d be very suspicious, a month after the job and he’s blaming you???WTF, over? Has he used since your job? Quote Link to comment Share on other sites More sharing options...

And honestly, an ENG camera shouldn't get fried over that. I've used ERXs on Amira's and Alexas with no problem. As you say, what could it do to a camera anyway? It was a two day shoot. Did you look to see if the scratch audio from the ERX was recorded properly on the camera either of the two days? If it was fried from the time you plugged in the ERX there would be no audio on those files. I'm sure you sent tone and set levels on the camera at the beginning too. The issue would have shown up then as well. So he had no shoots that needed audio for a month? Sounds suspicious to me. Quote Link to comment Share on other sites More sharing options...

Mungo Posted September 11, 2019 Report Share Posted September 11, 2019 That guy has no clue about audio gear! He just wants to find some fool who'll pay his repair. Maybe someone used a 5 watt China Walkie Talkie in close proximity to the camera. Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted September 11, 2019 Report Share Posted September 11, 2019 If you didn't experience any anomalies when you did the gig, treat his comment as a question, "No, it was working fine when I used it." Quote Link to comment Share on other sites More sharing options...
glenn Posted September 13, 2019 Report Share Posted September 13, 2019 This would be impossible. The ERX can only output audio and is not DC coupled so it can do no harm. Glenn Quote Link to comment Share on other sites More sharing options...
JonG Posted September 16, 2019 Report Share Posted September 16, 2019 There you have it. The guy who invented the Devices says it’s impossible. Next question. Quote Link to comment Share on other sites More sharing options...
Brian Liston Posted September 17, 2019 Author Report Share Posted September 17, 2019 I had a lovely conversation with the tech at Arri who worked on the camera. He agrees that there is not enough current from an audio device that could do any damage. The fault occurred from a short between the PSC port on the front, and the EXT port in the back. Neither port even has the type of connector that we ever use in the audio world. So yeah, zero percent chance. I think this guy was just looking to place the blame elsewhere. Of course I had the tech write up a note, and it was sent to the producer. Case closed. Quote Link to comment Share on other sites More sharing options...
