Ametuer audio to camera?
« on: March 26, 2012, 10:06:25 am »

I need to run 2 1/4" TRS outputs from a Presonus digital mixer about 50 feet to 2 RCA inputs through the AV connector on a small Sony HD camera for a church podcast. Can I just use 50 ' balanced cables with an adapter? Other options for hopefully noise free operation?

   Yeah , it should work.   Try it before the event, just in case.

John....

I always, ALWAYS use some sort of transformer isolation when sending signal out from a house console for cameras, broadcast, recording, etc....   A lesson learned the hard way when getting noise back courtesy of some consumer (or pro) level power supply.

In addition to going form balanced to unbalanced you also need to look at what type of level the camera connection is looking for. If it's a consumer or even low end "pro" camcorder with just a 1/8 inch mic jack for audio input you'll need a pad on the line as well. Depending on the camera there maybe a menu option for the line level audio input. The 1/8 jack will most likely be a TRS for a stereo mic input. Whirlwind makes an interface box for just what your trying to called the LM2C camera mic adapter. Also for a mono less cost option look at an RDL TX-LM2 line level to mic level transformer, I just used the RDL part at a church install to do exactly what your looking to do.
