AD/DA simply means an analog to digital conversion or a digital to analog conversion. The difference between the 2 is like the difference between a record and a cd. A record would be analog and a cd would be digital.

To get the best quality sound when record, limit the AD/DA conversions made. An example of this would be an guitar FX board. The signal from the guitar to the FX board is analog...once it reaches the FX board, the signal is converted into a digital format to apply and process effects...when the signal goes from the board to your AMP it is converted back into an analog signal.

If you keep the number of conversions as close to 2 as you can, you'll have the best sound.

In my recording setup I have a Fully Automated 32-channel digital audio mixer with 24 bit AD/DA converters. Now that's a bunch of humbo jumbo that allows me to do the following:
When recording I use a GNX3 guitar fx board. I can output digitally from this board into my mixer. My mixer keeps the signal in digital format and combines it with vocal mics and my roland electronic drumkit and then outputs it in fiber optic format(which is still digital) into my SB Audigy soundcard which accepts a fiber optic input. So when you play back the audio, you are only hearing 2 conversions:

1) The guitar's analog output converted into digital format from my FX board.
2) The analog conversion when playing back recorded audio.

The signal does not get converted from the time it leaves my FX board until I'm ready to listen to what I've recorded.

Hope this help improve the quality of your audio recordings. Or maybe you can just impress your friends with the new found knowledge wink.gif

I run my signal through DD20, to amp, then to Toneport, thats 2 conversions with cheap digital converters and I don't think anybody could really hear the difference..
But I do agree that converting has to be top notch if you are doing a studio project for example...
