First, you should know that in order to make an audio CD to play in your car or home CD player, you will need to make this file a 44.1 16 bit Stereo file. You can record into the system in whatever flavor makes you happy, but in the end, if you want to put this material on CD, you'll need to convert to Stereo 16 bit 44.1. Most folks just record at this rate...saves lots of hassles, but our DC SIX or Millennium can both convert to whatever you want.
If you're working with a stereo 45 or LP, this won't even be an issue. But if you're working with an old 78 recording, though your heart tells you to record in Mono, there may be some significant benefits to recording in Stereo. One of these benefits will be the ability to choose between groove walls. In some cases, this flexibility could give you one wall with much better audio information than the other. Having both recorded separately allows you to reassemble your audio using the best audio information that you possess. After recording your file into the system, DC SIX will allow you to jump back and forth between left and right so that you can determine if there is a significant difference between the two.
