I am returning to video after a long break and will be using my - now quite old but still works well - Panasonic NV-DS11, mini-DV camera.

BUT... it has always had lots of onboard motor-hum & zoom noise from the internal microphone, so I want to use an external one.

Although I have tried plugging in a few different stereo & mono mics, none work when plugged into this camera. It has been like this since new.

QUESTIONS:
1. Do Panasonic have their own peculiar mic input that will only take panasonic mics?
2. Is there a switch/ menu option I need to change?
3. How do I test to see if the input is okay?
4. Where would I get a panasonic mic for this early DV camera?

If anyone can help - many thanks
