Hi,
I'm building a camera shoulder rig and want everything (camera, monitor, light, microphone) to run off of the same battery. So I made a power distribution box with step down voltage regulators.
Everything works great except for the microphone. It's making some weird pulsing sound. I'm assuming it's the power feeding back thru the output. The reason I think that is because if I power the camera with its own battery the mic works fine. the only time the problem occurs is when the mic and the camera are both working off of the same power supply.
I've tried putting a capacitor between the + and - and also tried using a diode different places inline. But those were shots in the dark and didn't work.
Any ideas would be great! Please dumb it way down tho.
Thx!
