Aren't standards fun? I reviewed the AudioArts Air-1USB broadcast console for Radio World about a year ago and was puzzled to see the meters not bouncing around in a manner I'm used to seeing. Turns out the USB port was glued down to 0VU = -20 dBFS.
I'm not done with analog studios as of yet. If I had to, I still could make up some gain somewhere with a simple little 5532 circuit. But coaxing a USB UART chip to give you a hotter level? IDTS. -ap ----- Original Message ----- From: "Gavin Stephens" <[email protected]> Subject: Re: [RDD] M-Audio Delta 44 +4db Output According to the manual, that card can only output +14dBu. So there's 10dB robbed by not having a proper +24dBu output. So if you are 'peak' normalising your files to say -13dBFS, the peak output of the card when set to +4dBu will still only be +14dBu - 13dB (if peak normlised files to RD default) = +1dBu output. Depending on what your transmitter is wanting you'll still be less than +4dBu out of the sound card. Even if you files were normalised to peak 0dBFS, the card would only output +14dBu max, so if you're average level (if you're not peak normalising) was to be +4dBu you've only got 10dB peak headroom for peaks to acheive a norminal +4dBu out. I am so over analogue studios for this reason alone, I like all digital to a transmitter that has an AES/EBU D/A with easy to adjust peak reference on a screen or app. No more all over the place output level's by prosumer cards. ----- Original Message ----- From: "Robert" <[email protected]> To: "rivendell-dev" <[email protected]> Sent: Thursday, August 15, 2013 10:35 PM Subject: [RDD] M-Audio Delta 44 +4db Output > This card is supposed to have a +4 out switchable with -10 default. > > Envy 24 control panel does not seem to have this switch. > > Has anyone managed to get around this ? > > System is at a transmitter and the inputs need more level.. > regards > > Robert Jeffares > Big Valley Radio > > _______________________________________________ > Rivendell-dev mailing list > [email protected] > http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev _______________________________________________ Rivendell-dev mailing list [email protected] http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev _______________________________________________ Rivendell-dev mailing list [email protected] http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
