How do you check the recording levels on the JB3 when recording optial in? 
Thanks,

Look at the meters?  What version of firmware are you using?

Don't know what firmware I am using.  I just got it new from creative.  Don't see any meter.  What firmware do I need?

any limiters scare me, youre just not getting "true" levels when putting a limiter on :)

You are right, you are not getting that clip that you would otherwise.  Don't get me wrong, you don't want the limiter to kick in at all (IOW you want to set the levels right!)  But in that rare case when something gets a bit louder for some reason, you won't be clipping and you will still have a useable recording.  When using a decent limiter, with the levels set where they should be, you won't hear it kick in.  Without it, that once in a lifetime recording is now trash...

another reason why I don't "calibrate mine.  I'd rather just get good at getting the levels hot and not have to use undue compression *shudders*.  SO far my Neuros has been very good to me about clipping.

Using a mp-2 you won't have compression... You will have peak limiting...

Compression squeezes the sound to be within a certain db range. If it is too low it will bring it up, if it is too high it will knock it down.   Peak limiting is exactly what it sounds like.  It limits the peak to afford you the possibility of salvaging what would be a distorted peak.  It is ONLY used to limit that occasional spike over the norm, not all the time.

COMPRESSION VS LIMITING

Compression and limiting are often confused because they have very similar characteristics. Compression is said to have a ratio of between2:1 to 20:1, and Limiters are thought to have a ratio of 20:1 to infinity:1.  In easier terms, limiting means that once the output level reaches a certain point, it can get no louder.

It isnt tho, if you set the limiter at 0db then you would not get anything higher, now if you are setting your levels correctly, you shouldn't be hitting 0.  With the limiter in place, you are going to limit what would normally clip to 0 db.  So basically it is a hard limit and that is why they advertise the mp-2 as unclipable.  If you run your levels too high and let the limiter kick in all the time, it is going to sound like ass, but then again, it was going to sound like ass anyway cuz you would have clipped instead...

You do that at the risk of levels that are too low... Then you have to "damage" the recording by normalizing...  Like I said before, limiters are to be used as a safety net.

This is a "feature" that many people will be resistant to use, regardless of how you explain it.  I'm still not completely sold on it, except for maybe acoustic recordings when the crowd is louder than the music...  I have my limiter calibrated but I don't plan on using it much.

I shared the same sentiments with Moke about acoustic music and loud applauses.  Most of the stuff I tape is very heavy, and within 30 seconds of the first song the loudest sound of the night will have been played.  If I ever felt the need, I am glad the instructions are here.

I'd set it up anyway.  That way if you ever decide you need it at a show you don't have to find your way back here to set it up. ;)

ummm, why isnt hitting 0db good???

i dont mean HITTING it, but an occassional "over" shows me that im getting the most of my 16 bits that i can!!

dont over saturate, but an occassional 0db hit iosnt that bad a thing, also depends on pre/ad too!!

An occasional over in the digital world is clipping... If you like crunchy sound (clipping) then go for it.  The idea is to use as many bits as possible WITHOUT going over...

Yeah these are prolly the same people that thought up cell phone plans   ::)

definitely wouldn't push overs on the mp-2.  That'll definitely ruin a recording.  Fucked up atleast 2 that way.

I run it hot on the Neuros.

I'm not trying to be an ass or arguementative.  I'm just saying that for the type of music I record, I don't think I need the limiter.  Maybe I can get armen to explain it to me in person.  I still don't see how it's gonna help.

Hey np, its a hard concept. 

But you said you don't run it hot on the MP-2 cuz it will ruin a recording.  I agree, and it wouldn't sound better if you used the limiter (running it too hot, as the limiter would be kicking in all the time, remember I said set the levels right, then add the limiter, this assumes that the limiter is set to max just before clipping).  HOWEVER, if you had a single spike that sent it over, that part would sound bad, the limiter would keep that from happening.  Any other time the limiter does nothing. 

Think of a limiter like a govenor (like they install on school buses, to max out at 55 or 65)  That govenor doesn't affect how fast you can accelerate to 55, doesn't care if you drive 25, but as soon as you try to do 70, it stops going faster, you do 55 and that is it.  The limiter takes you to the limit before clipping and thats it.  Below that it has no effect.  Does that make sense?

I know what it does, but it won't help me.

I have a question.  If I were to use the limiter and follow MattD's instructions, I would need to adjust the levels on my MP-2, correct?

Well, the once in a lifetime will probably not be trash.  I've had to use the clip restoration function in CoolEdit a few times, generally for fairly mild clipping.  Just recently I had to use it on a recording I got (not mine) that required 9db of attenuation and clip restoration to get back down to 0dbFS.  It still sounds really pretty good after the fix.  I would hope that most of us taping don't ever overshoot the mark by much more than 9db.   Not that I'm recommending this approach at all, but you can do a lot to save a fuct recording using Cooledit or the other sound programs.

I think you're overstating the case here.  Clipping means you are trying to go over 0dbFS which can't be done in the digital realm, so all samples are set to the highest level--0dbFS (zero decibels full scale).  So if you look at the waveform it will be flattened at the top.  Theoretically, this will not sound good.  But in a practical sense, if you have a short duration clipping event, say less than a fraction of a second, you will not hear it.  If a tree falls in a forest and no one is there to hear it, will it make a sound?  If you clip for such a short duration (and only need say 1 db more headroom to not clip at all) does it sound bad if no human being has near the aural accuity to hear it?

Certainly clipping should be avoided and more serious clipping events will not sound good.  But a single drum hit that sends a spike in your levels resulting in a mild clip will not be detectable to human ears, so I have a hard time saying it sounds bad.  Contrast with the fact that I like to have my overall recording levels of my CDs about at the same level (-2 or -3db to 0db), and if they are too low, I will boost my levels in post-production to normalize them closer to 0db.  I can hear this, since the normalization process very (very, very, very) subtly changes the soundstaging cues, and the amazing soundstaging I get from recording on the V3 is lost to a degree (though admittedly a very small degree).  So for me personally, I do not hear any clipping sound effects when I have the occasional mild clipping, and I do hear a degradation of the sound of the original tapes when I run the signal through some sound processing software (even to just normalize).  Thus for me, I am willing to have the occasional very mild clip to get the best signal onto tape (for my way of listening) without the need to do post production processing.

Bottom line, this really isn't a right and wrong thing.  There are tradeoffs in how we record and listen and different people will have different ideas on what they prefer.  Clearly, you and I differ in that, but I'm not willing to concede that the tapes I've made that have had very mild clipping (and remember, my V3 lights the clip indicators up after three 0db samples in a row) sound bad.

All that said, I think the limiter function of the mp2 is an _extremely_ useful function to have when you stealth tape, and I often miss not having mine still.

1db I would agree you aren't going to hear, having a peak at 3db would prolly sound crunchy.  For your situation setting the mp-2 to allow up to 1db would work well, and anything past that would start to get nasty sounding so it is a trade off, have clipped peaks that are not recoverable (I know that there is software that tries, but it never makes it as if it didn't happen to begin with) or lose a bit of soundstaging and have an unclipped recording.
 
For recording situations where the dynamic range is fairly limited (i.e. a loud concert) a limiter is not going to help you, agreed.  For situations where you have a very wide dynamic range (i.e. vocals) you can think you set the level correctly and find that the singer just went from a whisper to 120+ spl, a limiter is almost a required, or at least the ability to ride the levels (which basically is what a good limiter SHOULD be doing)

Would I run it all the time?  No, but there are situations that without it, you would have to constantly ride the gain just to get a usuable recording and in doing that it might not sound any better than if you had used a limiter... 

All that said, it is a good idea to have the limiter preset on the MP-2 so that if and when you decide you might need it, it would be there.  Without setting it up for your recording device, you won't have that option.
