jimrankin Posted January 4, 2012 Share Posted January 4, 2012 Anybody used their new Hero2 with the outboard microphones input? I'm seeing a few different mic's on line but have NO experience with recording live so DNK what type is best or even what input is required for the GoPro (waiting on an email from GP support for their input, if they can actually figure out the request). Got some good previous input on placement and have been looking around the car for "out of the way" locations that seem good for motor/exhaust/tire pick up so just lacking something to stick there. Want to play with the GP2 before I put the car away for winter upgrades just in case spring gets here before I get them done. Link to comment Share on other sites More sharing options...

jimrankin Posted January 4, 2012 Author Share Posted January 4, 2012 Interesting post but I didn't find anything about the microphones until the very end. The only one that was mentioned as having been used included a battery when I looked at it on line. That probably answers the question of if external power is required or if the mic input is internally self powered. Leave it to GoPro to always be 2% short of getting everything right. Must be their location over on the coast, too many "smoke breaks" with those funny hand rolled doobies. I'm always forgetting to turn off the GoPro Hero 1 I already have so now I'll probably be getting "no sound" from my dead battery microphones instead of just wind noise. Better pick up some more ginko billoba or a stack of mic batteries. LOL. Link to comment Share on other sites More sharing options...
Croc Posted January 4, 2012 Share Posted January 4, 2012 (edited) This is what I used for the Go Pro 2 - worked fine as you could see on the NJMP test day: http://www.amazon.com/Olympus-145045-ME-15-Microphone/dp/B000815CF4/ref=sr_1_3?ie=UTF8&qid=1325708144&sr=8-3 The bimmer forums refer to this mic: http://www.amazon.com/Audio-Technica-ATR-3350-Omnidirectional-Condenser-Microphone/dp/B002HJ9PTO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1325708293&sr=1-1 I also tried this one on my POV VIO and it was passable but pretty cheap and the clip broke first time. THe Olympus was better quality sound. http://www.amazon.com/3-5-Computer-Clip-Mini-Microphone/dp/B001N0W2B6/ref=sr_1_22?s=electronics&ie=UTF8&qid=1325708363&sr=1-22 The Go Pro 2 is internally powered so no powered mic is needed - just a simple plug and play one.

jimrankin Posted January 4, 2012 Author Share Posted January 4, 2012 That makes it easier as a lot of the Mics I was looking at on line asked for 1.5 t0 10.0V internal or an outside battery power source. Link to comment Share on other sites More sharing options...
jimrankin Posted January 4, 2012 Author Share Posted January 4, 2012 MM Series BSN-1 stereo microphones. You get two mic's with a 6' cord on each, windscreens, stereo plug and little clips for mounting. The 6' cord may be right at the minimim for going forward in the car from a roll bar mount but they look like fairly good quality. One site has them customer rated at full 5 of 5 stars, didn't see ratings on others. About $60 or so. I may just spring for these so we have a "test" for future reference.

joshesh Posted January 5, 2012 Share Posted January 5, 2012 I'm new here, no se7en yet but seriously thinking of selling my evo 9 and building a Birkin. I recently bought this microphone from sony, its $60 but it takes great sound in full wind situations as long as you mount it at a low wind area like under the seat. It requires a small watch battery, I tested it out on my dad playing acoustic guitar and playback was very realistic. Very nice setup, much better than the GoPro HD1 that had the worst wind noise problems. Link to comment Share on other sites More sharing options...

Croc Posted January 19, 2012 Share Posted January 19, 2012 I just got one today for my birthday, gonna give it a "go". I take it you drilled a hole in the housing for the mic? . Happy Birthday! I ordered the kit with the skeleton housing and there is a pre-drilled hole. I wanted to keep the watertight housing for snorkeling. However, if you do not need a watertight housing then I have read on the GoPro forum that people are just drilling a hole like you suggest. I also sealed up the internal mic hole to prevent any wind noise coming from that angle. Link to comment Share on other sites More sharing options...
jimrankin Posted January 19, 2012 Author Share Posted January 19, 2012 Got a return email from GoPro about the microphone questions I had sent in. The power out of the GoPro is about 3V which is OK for powered microphones in "nornmal" situations. They did not know what microphones had been used for testing and gave no product suggestions. I did a little research and it turns out that powered microphones are usually optimized for 9V but do "work" down to about 1.5-2V. I love the GoPro video but as I posted before they always seem to find a way to shoot themselved in the foot with their audio. People who buy GoPro's are most likely not going to use them in "normal" conditions. What I found out about the "voltage/power" was that at 3V the microphone can not capture loud sounds without distortion. With a 9V input the microphone can reach it's full rated frequency and SPL ratings. So, in short, you are going to need to add an outside battery power source to use it for most anything but recording the family at Christmas dinner, and even that might be a problem if deaf old uncle X talks too loud. Been tweaking on the car so haven't gotten around to playing with the new GP2 but will post results when I do get a set of microphones. Link to comment Share on other sites More sharing options...
Kitcat Posted January 19, 2012 Share Posted January 19, 2012 GoPro 1 does not have an external mic port, right? I am stuck w/GoPro's abysmal built in mic? Mine doesn't work anyhow, so maybe it is irrelevant. Link to comment Share on other sites More sharing options...
jimrankin Posted January 19, 2012 Author Share Posted January 19, 2012 No external mic port on a GPHD1. No way to modify it according to GoPro. I was told that you can send away for a product sample of "Sonex" foam (or any competative product)and the piece you get is big enough to glue to the back of the "open" door your GP1 motorsports kit came with. It cuts down all sound but mostly wind noise if you trim it carefully.You then turn the volume up to compensate. Anything has to be better than what you get now.

Croc Posted January 19, 2012 Share Posted January 19, 2012 I have seen on a few forums that furry back (refer Mopho's pic) does not work that well but does cut down some noise. As for Eyeofmine - I use their roll bar mount with dual gopro cam adapter and it is brilliantly simple to use and stable on a seven on a track. I threw the Go Pro roll bar mount away as it just was not as stable. After reading Jim's post then I want to try a powered mic as that should improve the sound even better than what I got last time with Go Pro 2 and the cheapy unpowered mic. Bring on summer - I want to try it out! Link to comment Share on other sites More sharing options...
MoPho Posted January 19, 2012 Share Posted January 19, 2012 Happy Birthday! Thanks! It's the big 40 (monday actually), I am almost catching up to all you old farts, almost.... :jester: I ordered the kit with the skeleton housing and there is a pre-drilled hole. I wanted to keep the watertight housing for snorkeling. However, if you do not need a watertight housing then I have read on the GoPro forum that people are just drilling a hole like you suggest. I also sealed up the internal mic hole to prevent any wind noise coming from that angle. I didn't see the option to buy a skeleton case, but I don't need it waterproof, so will drill it out.

Bring on summer - I want to try it out! I picked up the same mic you are using, will see how that works with some foam on it before buying a powered one Foolishly I had a brain fart (getting old, see above ) and bought the GP rollbar mount, why I don't know considering I have a case full of professional camera mounting equipment :banghead: I will see if I can return it.

ronnie Posted January 20, 2012 Share Posted January 20, 2012 I have a Drift HD camera, but have the same issues. I bought an external mic, no known brand, but it did have its own battery and a 3 meter cord (about 10 feet). I taped it on the rear wing right next to the exhaust tip. There is room for improvement, but way way better than the mic on the camera. I now want to try fitting it on or near the Webers, inside the engine bay.

yellowss7 Posted January 20, 2012 Share Posted January 20, 2012 Ronnie, I'm looking at purchasing the Drift HD cam. What's your thoughts on it? Tom Link to comment Share on other sites More sharing options...
ronnie Posted January 21, 2012 Share Posted January 21, 2012 I love it. It's very light and compact, so fits in tight places more easily. The built in screen is great for getting exactly the right frame, and the rotating lens is very helpfull when mounting the camera on strange places. The image quality is very good, but you are stuck with the very wide angle lens 170 degrees of vision. It has a standard thread tripod mount system , so you canuse any kind of photo camera tripod, monopod etc... It's splashproof and I think that is enough for car based videos. If you want to go scuba diving you can buy a case. The few negative aspects are the lousy microphone at speed, the remote control is not very reliable and the mic jack is 2.5 mm so I have to use an addaptor to fit the usual 3.5 mm microphone jacks.

yellowss7 Posted January 21, 2012 Share Posted January 21, 2012 Thank Ronnie. I was curious about the 170 degree field of view. Is it really distorted? (fisheye) Some of the sellers on EBay offer replacement lens with smaller fields of view. Wondering if that would be a good option. Tom Link to comment Share on other sites More sharing options...
MoPho Posted January 21, 2012 Share Posted January 21, 2012 If you want a narrower FOV you should take a look at the ReplayXD it has a 135 degree angle of view. I was seriously considering this one as it offered an external mic before the GoPro and it looks a hell of a lot cooler. Ultimately I went with the GP2 after talking with my aforementioned friend who uses them for car commercials as he said they tested a lot of different cameras and settled on the GP There is also a lot of aftermarket support for the GP even other lens choices if you are willing to modify it http://stuntcams.com/shop/gopro-m-17.html Link to comment Share on other sites More sharing options...
