Wow! It's amazing! When you are using 20$ "thing" for many years and then installing Delta... Such a clean sound! So much "previously unknown" details! :D Well. In fact, I'm having a question... Would I open a new tread just to say how happy I am? :)

I would like to ask you, Delta 44/66 owners: if you are recording "Delta Multichannel" in SoundForge, Samplitude, Logic, or whatever you have, while NOTHING is conected to any of Ins (!) - what is a "peak level" of "silence"? Yes, I mean... there are some "shhhhhhhh" noises, so what level does they rich?

I have Delta 44, Sound Forge 5.0, recording "Delta Multichannel" without anything conected to Break-Out Box: result - -80dB noise! Is this normal?

I use the 1010 and I get a -93dB reading.

-80dB is quite respectable. Normal, probably, very quiet though. I tested all 8 inputs and they all are within a 1/10th of a dB at -93dB.

This was on wavelab, but the results should be very close if not exact with SF.
 
Yes this is quite normal and is one of the biggest difference between the SB Live type card and a Delta 44. It is believed to be the breakout box that eliminates the high noise from the card, but i cant go into much detail about that. But it has something to do with the converters being out of the computer away from the voltage of the PCI card and stuff.

Darnold
 
Emeric, -93dB and -80dB is a huge difference...

Actualy, this story beggins a long time ago. :) Last year I tried to "upgrade" my 20$ sound card to SB Live!, but I was out of luck. SB was SO noisy, it had not only shhhhh and high-frequency hissing, but also some "scratching" noises... SB support replied - it's probably "bus noises". Yeah, I have a noisy PC. I think, that's basicaly my motherboard, which is pretty cheap and from not-well-known-manufacturer.

And now, with Delta, noises are still very high. It seemes the only way to fix this - buy a new PC! (Of course, I can try to change only motherboard, but in my case, if I'll UPGRADE everything I need - I will spend more then a new PC costs.) Eh... A half-year I seriously started with home recording, and I realise, that in the next few years I will spend all my money ONLY for my home studio improvement.
 
Lucid,

The noise floor on my Delta66/Omni studio is reading a steady -80.76dB

thats about the average for a Delta44/66... certainly nothing to complain about. If it bothers you seeing it, then just setup your meter so it shows a range from -60 to 0 instead of like -100 to 0

the delta1010 has better number because it is a better card... Midiman used better quality converters and what not in it.

-80dB for a noise floor is nothing to shake your finger at though...
 
Yeah, good idea: I'll just set level meter to do not show me that -80dB noise, cause it's realy making me nervous, when I see it jumping on "silence". Thanks for replies. I see now there's nothing to worry about. :)
 
Hi,

I'm using the OMNI Studio with Delta 66 card and it's extremely quite, and a great audio quality.

I got my Line6 guitar POD plugged into the two pre-amp Line 1&2 ins on the OMNI, and even with all VOL settings at MAX I get absolutely NO background noise whatsoever.

Please note, I don't keep everything on max :-) coz I don't need to, I'm just giving that for a test example....

In fact it's complete DEAD SILENCE until I hit the strings - can't quite believe how clean the sound is :-)

Also, the headphone OUTS are the same, no hiss, nothing even turned right up to "ear drum" wreckage levels.....

The Delta is certainly the best audio card I've used to date.

IF I have anything negative to say - well, I think the "Control Panel" could have been better designed...the layout is OK, but not great, and should have been more 'visually appealing' in my opinion.....especially fro a pro level product.

Just my 2 cents worth,

KEV
 
hmm

I dunno... the -90dB is for the line in...

it says in the paragraph that the mic-in noise floor climbs to around -70dB...

the -80dB readings I was getting on the Delta66/Omni were on channels 1 and 2, the XLR mic inputs... I haven't tested the 2 line ins on the Omni to see if the noise floor was lower or not
 
Just tested my M-Audio Audiophile 2496. The noise floor is around -85dB with the analog inputs.
