I've been assigned to document our class's stage play and I'm having trouble with the audio. I only have one shotgun mic (3.5mm output) and I'm planning on putting it on a tripod and leaving it on the front row. Problem is, my camera's going to be at the back, about 25 feet away. The problem is, how do I bridge the gap between the camera and mic?
I've been thinking of just making a 25 feet long 1/4" plug microphone cable connected to the shotgun mic with a 3.5mm-1/4" adapter. It'll all go into a mixer, which will output to my headphones and straight into the camera. But, won't a 25 feet cable be all noisy and stuff? I've been reading a bit about balanced cables and they seem to be the way to go. However, I've heard that you should never mix unbalanced outputs (the mic) with balanced inputs (the mixer). Are there any possible downsides to this kind of setup?
