Audio-Technica PRO 24-CM Stereo Condenser Microphone

I'm using the Audio-Technica PRO24CM on a GoPro Hero 2 cam. I have been very pleased in the sound quality of the microphone. It's a big improvement over On-board mics on camcorders which are not ideal for good sound recording. They tend to pick up sound from all directions, like behind the camera and sound almost tinning and hollow. For those who have used GoPro cams know that the GoPro on-board mic record audio so-so and that's why most videos shot with a GoPro are mated later in post with soundtracks. Now that the Hero 2 has a mic input jack we can now record better audio using external microphones.The PRO24CM was within my budget and works like it was designed. Because it's small, I use it for my close up video work as well as for general projects. There are better microphones on the market, like brand and model specific for many camcorders but they cost lots more.

I tested it with Sony DSLR a560. Without the battery I can hear a sound like a working motor (quiet though), but I did not mount it on the camera, besides, the camera was recording at memory stick not on a HDD or like that. My guess, that this was an EM interference. Without battery there was mono recording - no matter what side from I would speak, the sound was on the middle in the playback. With battery in, the interference was 99% gone, but hiss is appear. Not much, but I can tell the difference in the quiet room or if you playing back through headphones, and - yes, there is stereo. When I compared the sound with battery out to the sound with battery in, the last one was more clear and a little bit louder. With the battery out, at the same distance from microphone (about 1 yard), the sound was like the battery was dieing: vibrating, more quiet and unclear. The camera battery was at 74% - more than enough to power a microphone.Of cause it might be the camera itself. But camera manual says that external microphone will be powered by camera. Well, and it does, but microphone in any way should record the stereo. But stereo recording works with battery in only. I wrote about this issue to Audio-Technica. Here is what they answered:"Although the microphone will operate using plug-in power, we recommend using battery power for optimal performance. There are no standards for plug-in power, so the voltage varies by device, resulting in inconsistent performance. This does not explain the mono recording issues; I have not had any reports of this. I recommend simply replacing the battery before important shoots; LR44 batteries are available at most drug stores, etc. and are fairly inexpensive."In two words. This microphone works great, the price is affordable, not for every camera - battery free, and Sony DSLR is needed "Hot Shoe Adapter".I liked sound recording with battery better anyway. So, I'm gonna keep it. Actually because the microphone does not have a power indicator, I'll try to buy some cheap digital portable button batteries tester and build it in parallel to circuity connection with switch to watch the battery power level. The test "Sony A560 HD Video Test / 1440x1080 " of Sony A560 with this microphone you may find on YouTube on my channel SergSpace.Update 11.26.2012 I recently upgraded Sony a560 to a65V, which has an auto focus in video mode. The built in microphone pick up so much noise from auto focus motor, that it's impossible to hear anything else. I do not have a SSM lens (too expensive), but this mike helped me to reduce auto focus motor sound dramatically. I still can hear it, but the noise went on background.

this mic is probably worth 39.95 and is what mics like this usually sold for before all the video hubub of late. it is flimsy and cheap plastic and can break easily. the sound is ok the windscreen semi-useless and the small size and placement picks up all the bad sound from especially camera noise ( fingers hitting buttons. anguish ,wind heavy breathing,,,ha)the positive aspect is its better than the built in mic,(using it on a Nikon D7000) and practical for carrying around.if what is shot becomes useful for any commercial or presentation use, sound editing will be mandatory. for a concert hall or open space , go with Zoom.

I have been a fan of Audio-Technica microphones since I first used them in the 1970's. This company has always produced decent sounding microphones which they design and manufacture. This is not a company that just buys "stock" products from OEM'S with their name on them, they design and control the manufacture the AT products from start to finish.To this end it's easy to say I've never heard a bad AT microphone. Sure some sound better than others but all of them sound decent, I've never had a bad one either which means their quality control is excellent. As a professional recording engineer I own microphones that originally sold for over $3000 each so I'm very familiar with what quality microphones should sound like. This little stereo mic is not going to be what you want for sound on a movie but for personal video it's perfect.The Pro 24-CM is a very compact and light weight stereo microphone which comes with a shock mount that is designed for attaching to the hot shoe of a DSLR. I bought it to use on my Canon 5D Mk III for improved sound when shooting video. The stereo pickup pattern is very broad and the sound quality is quite natural. The microphone is very light weight, has a fixed output cable with a 1/8" TRS plug and it's just about perfect for my application, I'm glad there is not more wire to deal with, it's perfect for my Canon DSLR.The microphone comes with a battery so if your camera does not provide "plugin power" (mine does not) you are still ready to go right out of the package. The battery is a small silver coin type and is supposed to last for 200 hours of use. I'm going to order spare batteries and keep them in my camera case so I have one ready when I need it.Overall I'm quite pleased and impressed by this little stereo microphone.Happy video and recording to all!

Angegebenen Daten erfüllt. Qualität Material wie Audioaufnahme zufriedenstellend

si lo vas a usar para filmar escenas o videos de youtube ni te molestes. no sirve para eso pesima calidad de audio

Buona qualità del suono ripridotto ma volume di ingresso molto basso con conseguente aumento del rumore se non usato adeguatamente vicino alla fonte. Servizio e spedizione ottimi.

Le microphone sonne quand même bien, le problème avec la combinaison d5100 et ce microphones en est un de gain, pour capter les sons ambiant de moyen à faible, je dois mettre la caméra à gain hi, sinon on entend rien, et alors si on met le gain à hi, il y a un bon bruit de fond...à haut volume, c'est mieux, mais c'est certain que le spectre sonore n'est pas semblable à celui de la référence...Donc je crois qu'avec un D5100, il me faudrait baisser le gain de la caméra et augmenter le gain du micro avec un pré-amp...
