Recording Ambient Stereo
using a SASS type mount of Radio Shack Stereo Clip-On Microphone
Here is a stereo rig that I designed to record ambient sound. It takes its shape from the Crown SASS microphone and is fabricated from plywood, Plexiglas, vinyl fabric, and the Radio shack stereo microphone (33-3028). I have tested the microphone with my SONY MiniDisc recorder (MZ-R-70), and my SONY camcorder (DCR-TRV340). Since the microphone is "Plug In Power" compatible it operates without external power on both devices, but it comes with a controller that has a battery for devices that do not supply "Plug In Power".
Recording of Vernal Pond (Wood Frogs?) recorded on the MZ-R70. (Fh3 mpeg compression). Is this a format that is available on most computers? It is one of the CoolEdit format choices. I transferred to 44 kHz stereo WAV format from the MD but even short samples are several mBytes. If there is interest in other formats I will upload them to this page.
Here is a recording made with my camcorder at a different part of the pond. I am on the shore of the pond with most of the action going on to the left.

This seems to cut down on some low frequency noise coming through my tripod mount.
