The BeachTek adapter series allows you to attach one or two XLR based mics and converts the signal to jack plugs typically found on many camcorders. Units mount via the tripod screw underneath your camcorder. There are separate level controls for Left and Right channels, a switch for Mic or Line level input, and one more switch for stereo or mono. All BeachTek's devices are passive and produce no additional sound, no hum, no hiss. These adapters are so clean they have become the industry standard. Adapters are available for most of today's professional cameras. Markertek is your source for BeachTek products.
