Re: New to external mics
 

...
Regarding field narration, I am looking for that option but don't to do it exclusively. As you suggest, live narration is very tough to do even fairly well, but it is a skill you can build. I have been working at it since starting with the prior HG10 in 2009. Hope that clarifies a bit.
...:-)[/QUOTE]

Actually it doesn't. I'm a "do whaver it takes to do it the best it can be done" sort of guy. If recording in the field means the quality will be compromsed, instead of trying to fit the round peg into the square hole by "building the skill" and making the best of it, I change the approach and do what I know will work better, In the case of narration I see no benefit to recording in the field but lots of potential negatives. So I'fd focus on pictures in the field, perhaps making notes to myself on a pocket note recorder if I felt the need, and record my actual narration back in the edit studio where I can focus exclusively on the task at hand and use the right equipment to get the job done a good as I can do it.

Re: New to external mics
 

Please let me continue what I have been doing such that I can use the Canon XA10? I really miss it. The HG10 was sold and so things are kind of at a standstill. The budget for this will not allow it to be done as you might prefer.

If giving out this sort of hardware compatibility advice, or not doing it "the best it can be done," is against terms of service here...

Can I just say I won't do it and ask how the 2 mics may be made to work (if possible) with the mixer?

Re: New to external mics
 

Forget the Olympus mic..... It is a mic made for domestic note taker recorders and NOT for serious video production.

If you purchase an audio mixer make sure it has the capability to monitor the return audio back from the camera.

Re: New to external mics
 

Brian. My productions are not that serious. Just trying to get something together on a very tight budget. The mic output has been tested and is perfect for my use. Its sound quality, balance of ambient and voice, and the fact that I own it already make it perfect from my view.

I've already used it and love the results. It is in line with or better than any lav mic at that price point.

Re: New to external mics
 

What mixer are you asking for compatibility information on, make and model? If it's the Rolls you pictured earlier in the thread, it has XLR inputs only so while the AT 875 will work just fine with it, the Oly lav will be a problem. Connecting the Oly through the Rode 1/8 to XLR adapter you pictured earlier takes the left and right signals coming through the TRS plug and parallels them both to pin 2 of the XLR. This means at best it will give you a mono mix on one recording channel only. But as discussed before, to give you any sound at all the Oly needs to be fed plugin power which is both a different voltage and fed into the mic cable in a completely different arrangement from the phantom voltage that mixer supplies. Connecting the Oly to the Rode adapter and plugging them into the Rolls (or any other brand) mixer will not give you any sound and turning on the phantom power is liable to destroy the mic's internal electronics. To use the AT 875 there's nothing you need do other than plug it in with a regular XLR cable, for the Oly lav there's nothing you can do to get it to work with that mixer.
You could custom build a breakout "Y" cable to take a female inline TRS jack you plug the mic into and feed the tip to pin 2 on one XLR, the ring to pin 2 on a second XLR, and the ground to pin 1 on both XLRs while connecting pin 3 to pin 1 in each XLR - that would get a stereo signal in through a pair of the mixer's XLR inputs, but it still doesn't solve the power problem - no sound without power but turn on the phantom and zzzzzp scratch one mic.

Re: New to external mics
 

Nick,

You're making me repeat myself, and that's why I'm getting annoyed.

In an earlier post I told you there are two basic mic powering schemes: phantom, and "plug-in power." I said clearly that those are not compatible.

You've posted the specs for the Olympus mic, it is "plug-in power."

You've finally posted the specs for the (rather non-standard economy) mixer, it is "phantom" power.

Therefore, that mic and that mixer are not compatible. You didn't need to ask that question... again.

Yes, in theory, they could be made to work together, if you had the correct interface electronics. But two sets of interface parts (one for each channel of the mic) would probably end up outweighing the cost of the mic.

Frankly, I've become rather annoyed by your ongoing stubbornness and unwillingness to accept suggestions from experts (hence my conclusion that you're a high school student). I am not going to attempt to explain all the necessary theory to you concerning the necessary interface electronics. And I am not going to waste my time looking through numerous catalogs to see if anyone makes the kind of interface that you need. Basically, you're asking for a huge amount of time and tutoring here, and generating a fair amount of frustration, because you're too cheap to replace your $50 consumer mic. (If you're really a doctor, you can surely afford a real mic.)

If you really want to persist with this folly, please take my previous advice: go to a dealer (reputable or cheap, as you prefer) and let them put together the pieces of the puzzle for you.

(My gosh, when I get chest pains, I don't go on some online forum, ask for a free diagnosis, and then disagree with what I'm told -- that's exactly what you're doing here. When I get chest pains, I go to my doctor and let him solve the problem -- that's what you need to do. Go to a dealer. Why would you NOT?)

Then the dealer will at least make a few dollars for all the grief, and you will have somewhere to turn if and when you're not satisfied or you want to make changes down the road.

Re: New to external mics
 

Thanks Steve. That makes things clear.

Greg, consider that your last point about the compatibility of the Olympus mic was this...

This comment was the sole reason I have pursued this option. Think about this. I posted the specs for the mixer I subsequently found, hoping you would tell me yea or nay, which you never did. You just got angry along with other posters, who were angry about things that weren't true (e.g. the Olympus mic was not even a lapel mic).

Maybe you are being too sensitive here. I've done nothing but compliment you and remained patient through a seemingly endless barrage of negative comments. I accept that you guys have tons of experience and knowledge and that I am just starting, and on a shoestring.

A happy conclusion is still possible. Is there a pair of lapel mics that I could twist and connect to the xlrs of my cheap mixer :-) that might sell for under ~ $80 together? I am not stuck on the Olympus. It just seemed reasonable to use it since it cost me $69 and made good sound. Now it has been stuck in the drawer back with its recorder - permanently.

Re: New to external mics
 

Quote.... "A happy conclusion is still possible. Is there a pair of lapel mics that I could twist and connect to the xlrs of my cheap mixer :-)"

WTF?

We are 4 pages into such a simple topic and at this rate will be onto page 8 soon....
I have never seen a more frustrating thread on a forum.

Re: New to external mics
 

Nick, the point is that I explained long ago about the two different (and incompatible) types of mic power. You have the ability to read the specs. The specs for your mic say "plug-in power" and the specs for the mixer say "phantom power." If you had taken the time to read the specs, and pay attention to the info given to you, you would have known that this was not a compatible mixer for your toy microphone.

There was no reason for you to waste time by asking the question again, when it had already been answered.

And, by the way, you originally didn't post any specs for the mixer, you just posted a picture. Now think about it, Nick, how much use is that little picture to anyone? I have repeatedly mentioned, and asked for, specs. How long did it take you before you got around to posting them. And even then, if you had read them yourself, you wouldn't have needed to ask.


What does that tell you, Nick? Are we all wrong? Could it be that there's something wrong about your approach? (But based on what I perceive as your huge ego, you will probably answer that we are all wrong, and your interaction here is absolutely rational and faultless.)

I am glad to answer intelligent questions, and glad to help someone learn a bit. But I am not here to answer the same questions over and over again, and I am not here to hold someone's hand. If I had wanted that role in life, I would have studied elementary education, rather than broadcast engineering.

Please get a clue: nobody here is going to recommend a pair of cheap plastic microphones that you can twist together.

Go to Radio Shack, they will sell you something that will fulfill your wildest dreams. With luck, they may even tell you it's a great idea.

Re: New to external mics
 

Brian. It is hard not to see that you and Greg are frustrated that I am not frustrated. Isn't that kind of a weird thing? You're angry at someone who is not angry at you. And that keeps making you angrier.

Please don't try to pin this on me. I'm a happy go lucky sort that ran into a brick wall of serious pride and ego. Participants in this thread have been and continue to be rude and insulting. It is not taken personally, I'm sorry to say.

It would be a false accusation to say that I have been unwilling to take advice. That's not me. Just read my last comment.

There is nothing wrong with my ignorance of the subject. There is also nothing wrong with my desire to make something low end work, even if it doesn't fit with someone's view of how things "should" be done.

Apologies for your state of frustration, but I don't see any of this as a refection of my personal ability to communicate or get along, so it really doesn't affect me.

I am a patient, bright and friendly person. Having a background in social networking, I am also well aware that it is very common for users to misread or read into statements due to the lack of normal social cues. The gang up on the new comer theme is also well represented.

If this is all good enough as is, then no good ending here. I am not a proud person and am always willing to try, sorry to say...

Re: New to external mics
 

Wow Greg, that's a serious effort to get the last word on everything. What actually happened is now all stretched out of shape.

Then a gigantically glib and insulting last line. Thanks! The brains behind this really important section on dvinfo actually despises me. Yikes!

Maybe you're like my cyber-bully : - )

Re: New to external mics
 

HMOG, what a shambles. I can't even be bothered to read it all it's become such a "never ending story".

Nick, why not just go for a cheap handheld (mono) voice recorder for the (by now famous) "David Attenborough" whispered field commentary and do some serious work on how you're going to get those 50' sounds?

I realise I probably missed some salient points over the last few pages, but coming back to basics for what one (1) man can do with a camera and sound gear out in the field, the old KISS principle holds, else it simply won't work.

Use the voice recorder for your third channel, forget bloody mixers and concentrate on how you get the other sound on the available two (2) channels.

Or am I being bloody difficult too?


CS

Re: New to external mics
 

No that is a great suggestion, which I appreciate. I considered the DR-40 (because I am needing stereo ambient sound recorded to), but here are the issues with it.

First

I often make lots of short clips (e.g. many macro clips using a Canon 500D diopter) and talk about the subject live in an interactive way. This means that while adding audio after is a simple matter, there are usually 20 or so clips per outing, so this post-mix approach (in my case) will add quite a bit of work.

Second

I was hoping to improve my past problem with voice level variation. This happens as my head repeatedly moves near and away from the camera as I interact with close-up subjects.

Regarding the 50', that is the really the very upper limit. I have used a shotgun with the HG10 and it served well for the types of clips being capturing.

HMOG :-)))

Re: New to external mics
 

Hmm, I sense the goal posts keep getting moved on this one.

Macro? Stereo? Nick, just how many audio crew are you taking out there?

Erm, WTF? Since when have you got the BBC WildLife crew on board?

Just what are we talking about here, exactly?

Honestly, I need to know what you're really trying to do before saying another word, because I think you're attempting the utterly impossible for a one man band and a zero budget enterprise.

(I have, however, been known to be wrong, so don't let that get in your way)


CS

Re: New to external mics
 

Just me out there (well others, but no crew. I'm not a professional). There have been no changes to my audio mix goal, which is this.

1. My voice
2. Ambient stereo
3. Shotgun (Booooo!!!! yes I know...)

3 (or 4 depending on what approach) channels into 2 camera xlr channels, all recorded in the field, hence the field mixer. I love the idea of a recorder but do not want to remix a gillion short clips after every outing. Personally I would rather limit post-processing. As a naturalist first, my mantra has always been to get meaningful content first requiring minimal video editing or photoshop-ing.

I've already been doing this minus the #1 above. My learner, was a Canon HG10 with a "multi-mode" shotgun mic. No crew needed. Doing what I do without one is not that hard. Been in photography since 1995 and a naturalist since forever. Just new to xlr. Camcorder on a tripod with a fluid head, me with a remote...

Macro working distance for this setup is 13". Plants are easy since they don't really move much.

WTF is kind of provocative, don't you think?

Why the big deal about narrating? That's what everyone expects me to do. I"m not a pro, but am very serious about this. Yes there are ever fewer naturalists these days. For good or bad, I love identifying trees, plants, filming spiders and all sorts of critters doing their thing.

Re: New to external mics
 

Well, well, now we're getting somewhere.............

Usefull info Nick, thanks.

WTF is about:

Qute how you have an interactive conversation with a plant or bug is a bit, er, out there.

At this point, it getting late and a lot of info to process, I might suggest we call a temporary truce here and all just return to our fox holes to rest up for the finale.

Off the top of my head Nick, I simply don't have any answers for you with your stated mission and expectations, so I have to try to process what, in my limited experience, could even come close to satisfying all of your stated requirements within the limited budget you have.

Hope that will hold till tomorrow, 'cos I'm out, for now.

Regards,


CS

Re: New to external mics
 

Nick, you are actually trying to use 4 sound sources.... The stereo mic is actually 2 mics in one case, there is a left output and a right output.

Re: New to external mics
 

Brian,

Please, don't confuse him with facts. I mentioned that earlier, and you yourself stated that two days ago. There is a real disconnect here where even simple technical details are concerned. (That's why I've suggested that he go to a dealer who can walk him through this whole process; but for some reason he's resistant to that concept.)

Re: New to external mics
 

As a photographer taking pride in the quality of his work, you don't want to produce out-of-focus or improperly exposed images do you? You don't mind cropping a still in Photoshop to tighten up the framing and render the subject in a more pleasing way, do you? So why should you give less attention and commitment to the quality of the sound you record than you do to the quality of the images you capture? Ansel Adams likened the image captured in the field with a camera to the score of a piece of music - and just like a score isn't music until it's performed, an image isn't a photograph until it's been refined in post production, in Adam's case that was the darkroom while in our case that's post production. Video are not made in the field in the camera, they're made in the editing suite in post-production. The camera original is only the raw material, not the final product, and is just one of the elements that comes together to make the final video production. Your voice commentary is another of the elements. And just as you need to do whatever it takes with your camera to capture perfect images of the subject out in the field, you also need to do whatever it takes to capture as perfect as you can recordings of your voice doing the commentary. That's why we're so critical of the frankly kludge'y half-way measures you've been proposing - not out of some arbitrary standard of "the right way" but rather out of an understanding of what works to produce a quality output and what doesn't work. We assume you want to produce a finished video that you can show in public and be proud of and we're trying to educate you on what it takes to accomplish that result. As a photographer you wouldn't be happy with compromised image quality and we're coming from the perspective that when you move from stills to video production you shouldn't be happy with compromised sound quality either. Sound is a crucial element in a video production and in many cases is even more important in communicating with the audience than are the images themselves.

Re: New to external mics
 

Wow. I've been following this thread from the beginning and all I can say is I'm glad I never jumped into this mess.

Nick, you have gotten some great advise and have been given some very viable options. All you have done is taken parts and pieces that you like to hear and tried to make it fit into what you think should work. Unfortunately there is no way to do what you want within your limited budget. Even if you designed you're own equipment the parts necessary alone would cost too much.

The people who have been trying to help you here are some of the most knowledgeable you will find on the internet and are a great resource to learn. But, since you are unwilling to take their advice I would suggest that you go out and just start learning through experience. You say you've used a shotgun on your previous camera and have identified a lav mic that you know will work to give you "good" sound that you are happy with. Then go and use them. You've been warned that there is going to be a compatibility issue with the power requirements and the equipment you have available. There may be some way to get them to work together but you'll have to look to another resource to find them because from the collective knowledge here they can't identify one.

You claim that the only problem you have is that you are "new to XLR". In reality you are new to a lot of what has been presented to you here and I think that is the problem. You are a classic case of someone who knows enough to be dangerous. In this case the danger is minimal as it is to your equipment and yourself. Unfortunately for some reason you are not taking the time to learn from the information that is being presented to you. So the only thing to do, is go out buy what ever adapters and other things you think you need and start to learn the hard way. Trial and error is an expensive way to learn but for many that is the only way they learn. The facts that these gentlemen have been presenting to you are not going to change and it seems nether is your idea of what you think you can do.

BTW, for all of those nature shows that you see where the host is narrating "while they're filming", watch them more closely. In most of the cases the narration has been done in a nice comfy sound booth to get that clean sound (it is then mixed with a lot of other sounds designed by a team to make is sound like they are out in the wild). Also, for the situations where you see Richard Attenborough out in the Arctic narrating, they go pick those up after they have shot the featured wild life. This is done for a few reasons, one, Richard is not that good. He does make mistakes and doesn't deliver the lines perfectly every time. So they do multiple takes of him delivering his lines. It is not real time narration. Also, most of those lines are tweaked by specialist after they have shot the footage of the wild life. You can't script a tiger or walrus doing a specific action just because you've written a line for Richard to read. The camera crew are out there for really long time. You think Richard is going to sit out there n zero degree weather for 8 hours waiting for that prefect opportunity to do his 15 seconds of commentary? Finally, they do not want to make any unnecessary noises as this will often cause the animals to spook. Again, look more closely and you'll notice that the narrator and wild life are seldom on screen together. If they are, it is rare.

I'm sure you will dispute these fact too because you've already tried it an you are getting results that are good. So, again. go ahead do it your way but this is what I've experienced from my limited documentary work and from what I've learned studying how well funded documentaries are produced. But, if what you want to do works for you and you're happy with it, then that really is all that matters in the end.

As for the rest of you in this thread, as Edward E. Murrow use to say, "Good luck, and good night."

Geeze, that turned into a much longer post than I thought it would.

Re: New to external mics
 

:-)

Steve, that all makes perfect sense to me. I'm heading in the direction vid post-processing, but...

Short of telling you my life story, there are real reasons I want to mix my voice while in the field. Aside from the fact that it is enjoyable and something I am learning to be better at, here is another item. A mid back injury really limits the time I can sit in front of a PC. You wouldn't know it from this thread.. Actually standing right now at a screen, and am a big user of voice recognition software to avoid the desk.

So... in a effort to round 3rd base, can I request the benefit of the doubt regarding field narration?

Brian I understand the channels, though not pretending to have much depth of knowledge. That leads to the desire to use the 4 channel field mixer. I'm open to either the 3 or 4 channel approach.

4 - one lav mic, one stereo for ambient, and one shotgun (can't afford this approach now)
3 - one small wearable phantom stereo mic (no such a thing) or 2 worn opposite facing lav mics for ambient and voice, and one shotgun

Since lots of lav mics are omni directional, the second option may be a good compromise. Yes less control of levels, agree.

All I need to be on my very grateful (actually already am) and happy way is some guidance on how to jury rig a couple of omni lav mics to work with the mixer, and maybe a suggestion regarding some on ebay that should sound "okay."

I really don't want to have to start processing many sound tracks on the pc now. It would be much better to get good with the equipment I have (will take months) and satisfy myself regarding my need to talk to bugs, plants, birds and armadillos in the field.

Re: New to external mics
 

Here's the cheapest solution for a decent phantom-powered lav I can think of off the top of my head ...
mate one of these - Ambient Eumel | Trew Audio - with one of these - Remote Audio Omnidirectional Lavaliere Mic | Trew Audio. Multiply by two for your attempt at stereo, though once again I have to say that IMHO it would be a waste of money since you won't get the actual stereo sound you're hoping for anyway - using two mics on your lapel will merely give you two almost identical mono tracks..

One big caveat - the Eumel adapter wants 48 volt phantom and the mixer you showed interest in only provides 18 volts. It'll work going direct to the camera but not through through that mixer. A higher quality mixer would give you full 48 volts and would be a much wiser purchase in the long run. Get the right stuff right from the beginning - the initial cash outlay might be a little higher but it's cheaper in the long run. Sound gear is just like camera gear in that regard - it's always more expensive to buy cheap and upgrade later than it is to get the good gear right from the start.

There is nothing that says you have to sit to record narration into the computer. In fact many professional voice talents stand or sit on a high stool while recording in studio. Better airflow, lung capacity, and chest resonance.

Re: New to external mics
 

Actually, as far as I am aware, most of the wildlife shots on the major TV programmes are shot silent and the sounds put on later in post production.

Re: New to external mics
 

Can't say if it's the same now, but Anglia TV up the road used to be the experts on wildlife programmes with their Survival series, and back when they were shooting film, they rarely had any recordings of anythng other than local sound for a wild track. All the sounds of insects crunching a smaller one and eating it, the sound of eagles wings and all the rest were either stock audio edited, or created from scratch. At one session, the actual sound recorded of a huge eagle sounded like feeble flaps that a small bird would make, not the huge scary sound everyone imagined. I was given a pair of old big leather motorcycle gauntlets, and holding them at the end with fingers furthest away, you could flap them up and down, and the sound was great - a great big eagle sound.

what worries me about the approach being talked about is that one person framing and focusing while talking, while recording clean wild track at the same time is going to be a mess. You can't have clean location sound if you're talking, because the sources will all leak - a bit of local sound in between words on the narrative track, and narration spoiling the location wild track - making editing very difficult.

Dub the narration on afterwards, and just get local sound.

Re: New to external mics
 

As long as he is doing TWO impossible things concurrently (shooting video AND gathering representative ambient sounds), might as well throw in a THIRD impossible task (recording live, sync narration) just for good measure. What worries me is that the OP hasn't the slightest concept how good sound is recorded or mixed and he steadfastly insists that the laws of acoustic physics don't apply to him. At this point we can only wish him luck (although I have little faith in that.)

Re: New to external mics
 

When I was teaching media at a college I was amazed how sound was just done so badly - mistakes so obvious that I just couldn't understand why the students messed up so badly. Trying to shoot interviews next to a busy road, and often next door to a peeping pedestrian crossing, or maybe not noticing the constant noise from the machinery in the factory next door. Material so difficult to edit it spoiled the product. In the end, I think my research, by watching them work showed that sound was a case of making sure levels were in the viewfinder or recorder display, and making sure something was in the headphones. Once they were sure some kind of sound was there, they concentrated on the video - not even listening to the actual audio. I'd see people with a fully extended boom, that wore their arms out so they stuck it in their hip 'notch' and then had it going up at 45 degrees, so the mic wasn't even pointing in the direction of the subjects! Nobody ever moved a microphone or changed their position because what they heard was poor sound, it was as if the question was "is there sound?" and as long as there was something, job done.

Maybe it is just me, but I cannot split my brain. If I'm talking into a microphone about something, I cannot focus and frame properly. I've even discovered that when I do start to talk, my attention goes from the viewfinder.

Next time you are driving through busy traffic, do a running commentary out loud on what you can see and what is happening - then look at the speedo. I bet you have slowed down considerably and not even noticed.

Re: New to external mics
 

To understand the massive circus that this thread has become, one needs to look back to the beginning of this thread.

The OP said he wanted to use:
Once you recall that the OP thought he could use one "omni mic" for stereo, you know we're in for a challenge because this guy has absolutely no understanding of audio. Even so, that lack of knowledge would be perfectly OK, except that the OP has proceeded to argue with all our advice.

Then, to make mattes worse, there's quite a bit of confusion in his statements.

In post #4 he says:
Then when he finds an old mic laying around, he changes his tune and says (post #11):
(Of course he's ignoring the manufacturer's specs which describe it at "2 x uni-directional" elements.)

Then in post #45 he completely contradicts himself:
There are a few other conflicting statements, too.

In post #62 he justifies his desire to mix everything live:
But in post #27 he said:
It's hard to understand why the "back injury" prevents him from sitting on a chair, but doesn't prevent him from sitting on a log.

I agree with Chris who said:
Yea, verily. Everything keeps getting changed, depending on the day and the OP's particular whim. With all this waffling and contradiction, is it any wonder I assumed the OP is a high school kid?

It's been quite obvious to me that the OP doesn't really want advice. He has conceded that he's not interested in getting the best possible audio. In post #32 he said:
and in post #45 he said:
IMHO this is just a game for him; he wants to be a one-man-band and a star. So be it. It's a big world and I'm fine with that (as long as he's in Texas and I'm in Pennsylvania).

I tried to provide several technical suggestions, but I've concluded that he mis-interprets (or ignores) details which I consider to be extremely elementary. So I think giving out more technical info is non-productive and maybe even dangerous. I've suggested more than once that he consult a local dealer, who can assemble a package that will meet his perceived needs. That would honestly put together the pieces of the puzzle, and get the job done. For my pains, the OP has said (post #52):
So I, for one, won't be providing any more advice, except to repeat my previous serious suggestion that the OP should deal with a local vendor who hopefully has someone on the sales staff with enough technical knowledge (and patience) to put together a working system, however unusual it may be.
