I like having lots of options.
Sure you could record audio from your camera or on Zoom H4N or H1, but here is another option using an XLR mic you could use with a laptop.
My wife volunteered to read some books for our kids school, so I thought I would give it a test.
Basically you connect a standard USB cable to your computer, and then connect the other end in to the preamp and then you can also plugin it in to the headphones for monitoring as well.
It works pretty well. But I have only used it once so I report back later when a I more experience with it.
I do a lot of podcast so this will be a good thing for me to use in the future.
I figure out the turning my sound card input gain structure down almost all the way and hitting the preamp as hard as I could gave the best signal to noise ratio.
