Low self-noise shotgun microphone
  • I have SoundDevices Mixpre and I'd like to get good microphone to it.

    I have already MXL FR-300 but I'm pretty disappointed with it. When I boost gain enough so that I can pick sounds with high sensitivity from 1,5m - 2m, there is a lot self-noise in the signal.

    To ensure that there wasn't problem with e.g. my cables, I did another test with Electro-Voice RE50 and there was absolutely zero noise. I know this is different mic since it's dynamic but atleast it proves that the connections are not the reason.

    At http://www.dvcreators.net/shotgun-shootout/ there is good comparison between shotgun microphones. It seems that there is really big differences between mic self-noises. E.g. AUDIO TECHNICA AT897 has pretty loud noise, I'd say that sound clip is unusable. But e.g. SENNHEISER MKH-416 has virtually no noise at all and the tone in her voice is excellent.

    I don't understand why anyone would buy e.g. AUDIO TECHNICA AT897 ? Is that much self-noise really acceptable to someone?

    Anyway I'd like to get some recommendations about shotgun microphones. Based on the test above MKH-416 is a winner for me but that test doesn't cover everything. Requirements:

    • Low self-noise
    • Can pick sound from 1,5 - 2m away
    • Good tone
    • Price range <1000$

  • From my experience the NTG2 is not that great a microphone, it seems to pick up reflections and creates a "nasal" sounding recording. I had much more luck with the MKE600 which is similar price, I got some really nice recordings with that mic that sounded far more professional than anything I was able to get out of the NTG2.

  • @spacewig hmm, there is a little bit of noise, but (the lower) part of it is actually background traffic noise picked up by the mic. Maybe the DR-100 added some noise? The mic is clean though. Even with full gain on the MixPre I only hear some slight noise in really quiet environments.

    1. The cable is indeed particular for mono shotguns. I don't have a specific brand or model though. In fact, I can't remember where I got the cable, sorry.
    2. Correct, no monitoring off the camera unfortunately. Not sure if audio comes through the HDMI. The bars are also a little deceptive, making the signal seem a bit stronger than it is.
    3. I can't seem to figure any way to adjust the input level without going into the menu. As I understand though, that level adjustment is also the level of automatic gain, so the highest boosts the signal most but also limits it.
    4. Yes, in Ptools if Pasadena Pulse is one of your preset settings you can click on it, then click on a second setting. The second setting will 'remember' that you loaded Pasadena Pulse, you just have to turn it on in the settings menu. Once you turn on the audio settings you can also adjust them. Hope that makes sense.

    Did you run the line out of the mixpre into the line in of the dr-100 in your mic comparison video above? If you did, was the NTG-2 running on phantom or battery power? I ask because it seems much noisier than it should be.

  • @MirrorMan I have a few questions I hope you can answer to your post above? 1. Is there a particular XLR to 3.5mm adapter you recommend? 2. I suppose there is no audio monitoring in this setup besides the bars on the LCD. Is that right? 3. Can the audio levels be adjusted during recording on the GH2? 4. When applying the Pasadena Plulse settings to hacks that don't have it, I suppose they can be entered manually, right? Thanks.

  • Here's another quick and simple audio test, this time comparing a Rode NTG-2 and a Sennheiser K6-ME66. Both are medium sized shotguns and have the option to run on an AA battery which allows them to be plugged directly into the GH2 (with proper cable and adapter). Using the Pasadena Pulse setting at 'level 3' I made 3 recordings. The first 2 are a direct comparison and the third a 'proximity test' with the Sennheiser. The Sennheiser is quite a bit more sensitive than the Rode but also has just a slight bit of noise with the GH2. But I'd say the Sennheiser is one of the best sounding mics I've heard with the GH2 (but is also more expensive ;). I made a 320k MP3 which I hope uploads here ok.

  • I've got an NTG3 and it is the best mic I've owned. Before that I had an old mkh-416t which sounded great but the rode is a hotter mic with a lower noise floor and is pretty versatile. It's the only shotgun I've used that sounds fine indoors in reflective spaces. I'm also going through a mixpre and line in to my fs100.

  • for @tonalt @spacewig @peaceonearth and others... Here's a quick test using the Rode NTG2 and two different recorders with the GH2, a Tascam DR-100 and Zoom H4N:

    I'll try to make a separate test using just the preamps of the audio recorders vs the MixPre.

  • @MirrorMan Could you post some audio samples? With different gain settings. I'd like to get some reference audio file to see what it should look like. Now I'm not really sure anymore.

  • Actually, the mic preamp I put up on this forum performs really really well in terms of clean gain and costs like $60 to make. Of course you have to actually build it but if you don't want to dish out $500+ for a decent pre it's well worth the effort. I use mine all the time, runs on two 9 volt batteries and there is just no comparison between it and the shitty preamps found on most portable recorders.

  • try recording 2 people sitting side-by-side with the H4N about 3 meters/10 feet away.

    You don't need to make such effort. One person 5 feet away is enough to hear how crappy these PreAmps are. I had it, I sold it, I lost almost 200€ and I would sell it again for the Roland R-26. The H4n may work if you have a high sensitive and low noise mic and are able to put it very close to the audio source so you can keep the gain low - but that's not reality!

  • @spacewig Thanks - good info.

  • @matt_Gh2

    Yes, I mean the preamps in the H4N are really noisy. The external mics are ok for relatively loud sounds. The unit, and others like it, is primarily targeted at musicians to record their jams or musical ideas when inspiration hit, and not intended for picking up conversation in a quiet setting from a mic sometimes placed a few meters/yards from the talent where clean gain becomes a necessity. Having said that, the H4N is fine as a line-in recorder, i.e. mic>preamp>recorder. I use a DR40 specifically for that purpose.

    @tetrapak

    The overwhelming majority of instruments are MUCH louder than the human voice. Next time you have a chance try recording 2 people sitting side-by-side with the H4N about 3 meters/10 feet away. Adjust the gain of the H4N so that the AVERAGE loudness is around -14db (peak around -8db). Now listen to the result in a quiet room through reference monitors/headphones and you'll see what I mean by noisy.

  • @spacewig do you mean built-in mics of the H4N? Its preamp on the XLR inputs is exellent and accessing SD card is noisless. Maybe you've got an slightly damaged device, let it be checked- otherwise H4N is really great. I use it often as 4-track recorder for classical music live performances (with another pair of mics via external phantom power supply plugged into chinch 3,5mm on the bottom side of H4N) and it sounds just brilliant!

    @tonalt does it have to be shotgun and hypercardioid? Did you try Neumann KM184? It is smooth and very natural sounding cardioid, so 1,5-2m are no problem, but you can put it also VERY close to the source. If you get a pair, it works also great as ORTF.

  • @spacewig I think you're right re: Zoom H4N. In working with lavalier mics, I prefer the Roland R-05 as I was getting some noise with the Zoom H4N. Maybe it's even more noise with shotgun mics. I'm just now testing my ME66 shotgun mic. When you say "I would not draw any conclusions regarding a mic if the H4N is part of the gain stage.", do you mean using mic and H4N without a mixer like SD MixPre? Thanks.

  • The H4N is disgustingly noisy. I mean you just cannot use this as a shotgun mic preamp unless you're recording an elephant fart or a chainsaw from a distance of around 2 inches. I would not draw any conclusions regarding a mic if the H4N is part of the gain stage.

  • I have a Rode NTG-2 which I use with my SD MixPre. I can push the levels all the way and hardly get any noise. If you have more budget, go with the NTG-3. Sennheiser ME66 is also good. If you record outside you will absolutely definitely need wind protection, so factor another $300-$500 into your equation.

  • See my experience here: http://www.personal-view.com/talks/discussion/3146/rode-ntg-2-with-zoom-h4n-problems-choosing-alternatives/p1 I ended up with ME66/K6 and Roland R-26 and after six month I am still very happy with this combo. I had the AT897 for a test and was dissapointed so I sent it back. I my comparision under field conditions there was no big difference to Rode NTG-2 which has low sensitivity and a lot of noise. Hope that helps.

  • @spacewig I will be testing my Senn ME66 with 2 recorders - a Zoom H4N and a Roland R-05. I have used them with a Audio Technia AT899 lavalier and found a sweet spot with the R-05, and prefer that. Will let you know how the mic works with both recorders once I test.
