Question: Is this stereo? Or will i have to buy an adapter?
Document: I had two issues with this microphone. First Sony on its web site says it is compatible with their HDR-PJ710V. It isn't. You have to buy a hot shoe adapter or a Flash Bracket to use with this camcorder.Second while recording with this microphone (luckily I had a Flash Bracket to test with) it would periodically pop and crackle.
i just bought it, and i just try it sounds ok. whoever looking to buy this product it is not perfect, but it is good.
This microphone definitely works for the purpose. Great clarity,well constructed and made out of good materials.Having said that, I was disappointed that the Mic was not able to mount on my Sony HDR-PJ580VE handy cam. It does not come  with a Active Interface Shoe adapter.
The audience below me was only obvious if there was either extreme quiet on the stage, or the clapping from act to act (a kid's talent show). *Came with adapter for regular cold shoe, or Sony quick connect to the flash mount (for my camera). A fine instrument and an excellent addition to anyone who wants to reach out and hear someone.
It seems slightly lower level than the built-in mics on both devices, but worked fine. (The battery didn't make a difference to that.) The plug is stereo, and the sound seems to be connected to both channels.The supplied wind muff is OK. It slides directly on over the front -- a little tight at first but it goes.
works like a charm
This worked great the first time I used it with my Sony a77. I used it outside on a windy day for an interview and it worked super! After that every time i use it i get a clicking and a hissing and a beeping in the audio that it records. I unplug it and go with the on board mic and all that goes away. I changed the battery and that didnt fix it. I also tried both settings and it happens on both...
This seems to work OK, although major handling noise is picked up; it could be that a bungee-type shockmount could help, if this becomes an issue.The mic stand has a cord clip on it, which I can't use due to how the cord routes on my camera. However the cord -- about 325mm / 12.8" long -- is nice and sturdy, and doesn't flop about, so this is no problem in practice.
This microphone is a nice microphone and if you just need to improve the sound quality of your camera cheaply, this is the way to go. This mic is not very directional and it picks up more surround sound that I like but again, it's not a high end microphone either. The shock-mount is very nice, cable is nice and thick and the connector is solid. The wind-muff does an adequate job of cutting with hiss and the low pass filter works as well.
There's not much info around about this mic, so I took a chance, and here you go! Hope this review is helpful.So far I've given this mic some light use outdoors on my Panasonic TM700, and it seems to work well. I've also tested it with my Olympus LS-10 recorder, and that seems fine too.
Answer: The mic is MONO - only one capsule inside.  The wiring is setup to plug into a camera's mic jack that appears to be "stereo" (or balanced) just like stereo headphones.  The mic sends the same signal to both Left and Right channels in the camera. So what you get when using it is mono sound, recorded the same on both left and right channels without any adapters. If you want to record separate Left and Right channels (real stereo sound) you'll need a different mic... or buy two of these and adapters to mount them and adapters to plug them in but that's probably not worth it.
