microphones

This product was a huge disappointment. The channel noise of the transmitter/receiver almost drowns out the speech signal. The Signal to Noise ratio is 10-15dB at best(useless), even with a higher quality replacement lapel microphone. When the same microphone was connected directly into the camcorder, the SNR was at least 40-50dB. I went back to the store to see if I had a defective unit, but the other unit I tried had the same characteristics.

I bought this for use with my Sony camcorder. I chose it because it was a 900 MHz system rather than the 100 MHz systems from Hysonic, etc. The included lapel mike is not very good. Lots of distortion and very cheaply made. I tried a better quality Radio Shack lapel mike, #33-3013 and got much better results. Compared to putting the mike right into the camcorder, the wireless transmitter shows considerably more noise and lower sound level. No noticeable difference in frequency response, at least for voice recording. Dropouts started occuring when I was about 50 feet away. Bottom line is this isn't broadcast quality but certainly adequate for amateur use.
