Default Quite Decent Cheap Lavalier Microphone

This inexpensive little RadioShack 33-3013 lavalier microphone model is quite good. $27. I've purchased five (5) of them.

Purchasers seem to be giving it positive reviews.

I just had a good experience with four (4) of these microphones and the Kodak Zi8.

I had two rooms.

Room #1 featured an interview between instructor and student.

Room #2 featured an interview between instructor and student.

So... two (2) interviews proceeded simultaneously.

I clipped the RadioShack lavalier microphone on each of the four (4) partipants.

I plugged each microphone into RadioShack 1/8" jack to 1/8" plug stereo speaker cable:



Then I plugged this cable into a RadioShack 1/8" dual mono jack to 1/8" stereo plug y-adapter.



This adapter has a gold input and a silver input.

Then I plugged this adapter into the external microphone input of the Kodak Zi8.

Then I set my audio levels using the Zi8 external microphone level meter.

Then I recorded the interviews.

Microphone #1 went to one side of the stereo track and microphone #2 went to the other side of the stereo track.

I was worried about using such long "unbalanced" cables with their weakness being they sometimes are vulnerable to noise issues, unlike balanced XLR cables.

But I ran into no noise issues.

I got very clean interview audio.

These hybrids all record "hissy" audio to varying degrees and the Zi8 is not without some hiss. So I used MAGIX Movie Edit Pro's built-in "dehisser" and "denoiser" (in the audio cleaning menu) and -- VOILA! -- a very good end result.

Oh no... not fifty feet. That would likely lead to noise issues with unbalanced cables.

I was able to connect two of the 8-foot long RadioShack computer speaker cables to the cameras for a distance of 16 feet. No noise issues. So I was pretty happy with the result.

I was able to play the finished DVD on two large projection screens and -- I have to say -- the video quality was really quite amazing.

Audio boomed over the PA system in the classroom and it was very clear and low-noise.

Well, one could use balanced XLR-style cables.

But that would require an adapter like this:



This type of adapter allows one to plug a short 1/8" lead into the camcorder's external microphone input.

Then one could plug very long XLR-style cables into the adapter's XLR ports.

The XLR cables are the ones that look like this:



You could plug the mic into an adapter like this:



Then switch the adapter's toggle to "mic" (rather than "line").

Should work for long distance.

One other good thing about the Studio 1 Productions adapter that I showed previously is that it has a GROUND LIFT toggle switch.

This comes in very handy if you're running the Kodak Zi8 with wall electric power. If you don't have GROUND LIFT capability, then there's a decent chance that you'll get audio HUM on your recording.

Of course, if you don't use wall power, but instead use battery power, then you won't get the hum.
