OUTPUT VOLUME ON EDIROL, NORMALISING AND MIC PRE-AMPS Can't Post

1) Those who have viewed this post will have read about the problems I have had with my brand new R44. I am led to believe by various sources that you should aim to get the input close to the clipping level (C) whether you are recording music or voice.

My problem has been that I can't get anywhere the C mark short of winding up Sens and Level to maximum but of course that is not practical becuase of the noise you get.

I have had long and varied phone discussions with Roland and they now suggest it needs to go to a technical service centre which will be a real hassle as I live a long way from one. I would also hate to do this if in fact the unit is fine and my expectations are unrealistic. What I really need is for it to be confirmed to me that if you are sitting 2 feet in front of your mic and were trying to record your voice at a "robust " level but not shouting, what level you would expect to see on your dbfs meter. Thanks for your own help with this Michael - you said that when you do a voice recording you have the Sens set to -20 (11 O’clock) and the input to ¼ way round (9 O’clock). At those levels a clap right in front of the mic only goes to 36 on my unit. It simply cannot record anything at sensible levels on those settings!!

2) The only way I can get decent voice recorded is to normalise in post but I don't think I should have to. Some peoople seem to normalise as a matter of course. In the process of responding to the above, would you be able to comment on your view of normalising and also whether if you are a R44 user whether you use a mic pre-map or if not, whether you think it would give better results to do so.

3) I have actually purchased a pre-amp and will be happy to post my observations of the improvement in quality. I think that would be of interest to folk. It is a US-made unit with the dubious name of "RNP" which stands for Really Nice Pre-Amp - model RNP 8380. It retails in Australia for about $1,000 (roughly the same in USD). It is uninspiring in terms of looks as the makers admit but they say they have put the money into its working elements. One of the comments they make is: "The RNP is a class-A circuit that runs about 6 times the quiescent current of typical class-A pre-amps". .. if that is of any interest to you purists. But I don't intend to use it until I know whether Roland have supplied me with a good R44 or not, and get it replaced if necessary.

Thanks Mark and Michael for your help with the volume issue to date.

I always normalize in post...not sure why you're so hard over in not wanting to do so.

Given what you claim are the readings with the setting you gave...maybe you should send it in...or at least try to exchange with your dealer. I continue to get great recordings with this unit without any pre-amps....

I will say that I was surprised by the levels I got from vocal recordings as well. But when I sweeten in post, I have found that the levels I get, when adding some amplitude are really clean.

My sense is that the limiters are so robust and circuitry so clean that you don't really need to shoot for anything over -12dB. When raising gain in post, you can have it as "loud" as you like but it remains clean.

My very unknowledgeable $.02

Many thanks Jeff. It's good to know someone else was surprised by the low level in voice recordings. And its certainly true that in post the amplitude can be raised quite a lot without introducing noise. Its just that I didn't think the R44 would need any "artificial" help. I guess I was just thinking in the absence of anything in the manual (and as a relative newbie to the field of audio) that I could transfer the files to my PC and everything would be sweet.

Thanks for the very useful tip about the -12dbfs.

I think I may send the unit back for a replacement/or check anyway as my batteries (brand new Sonys - 2300 15/51's - exactly as per the specs only go for about an hour (with only one channel recording and at 44,000 only) and then when a tiny little diamond shows in the upper hand corner of the battery meter (which is supposed to mean there is heaps of charge left) within a minute it goes to half way - then in another minute the battery warning light comes up and it turns itself off. It does exactly the same thing with another set of brand new batteries.

My sense is you don't feel that a pre-amp is necessary. Hmm....that's food for thought

Thanx Mark, its just that as per my post in reply to Jeff I thought I could just take it out of the box and produce tracks with a sensible volume. Boy, am I learning stuff fast. But there again, I am starting from a low base!!

Thanx for your comment re pre-amps. Maybe I was seduced by the salesman.

But I do need to knwo what I am doing. I have the priviledge of recording (non commercially) the winner of the 2008 Sydney International Piano Competition (held every four years) on the 15th and I need to be prepared and do justice to it. I am using my two Audio Technica 2020 mics plus two Rode NT-6 mics (the latter suspended from the ceiling).

I did a recording just using the AT's several weeks ago and was very pleased with the sound (albeit volume too low as I did not normalise). I expect this to be even better as the Rodes will pick up "atmoshere" as well as add another two channels.

Bryan,
Also if it helps, I bought Powerex Rechargeables on NewEgg and I can run at least 3 channels on phantom for 4+ hours. I actually ran one reception with channels, another reception with one channel before they ran out of juice.

I highly recommend them.

Yes Jeff, rechargeables are twitchy things and unreliable it seems - even recognised brands. And it only takes for one of them to be a bit weak to make a unit shut down. Thanks for the tip on the Powerex - I will see if they are obtainable in Australia. A field recorder isn't really such if you have to sweat over the battery meter constantly and worry whetehr you've got 5 sets of spare batteries on stand-by!!

Sorry - correction requried to my earlier post about the Sydney Int Piano Comp - Not the WINNER but the runner up and also the winner of the prize awarded for best overall performance. I need to correct this because the world is now a small place!
