External Microphone on the Same Frequency

Hi all,

I have the wireless Azden WMS-Pro lavalier mic that I bought recently. I was wondering what would happen if I bought another set and set both transmitters to the same frequency as the one receiver on the camera.

Would the receiver be able to pick up sounds from both the transmitters?

No. Probably the one with the highest signal strength (not necessarily the ludest audio) will dominate or other wise you get a jumble with a lot of interference and noting you can use.
Radio waves on the same frequency interfere with each other.

However you would be able to use two different transmitters and receivers on nearby frequencies (channels) for the eft and the right stereo channel.
