I bought it to digitize my VHS movies to DVD. The version I have was purchased on the Internet and it has a button to disable the Macrovison (crap used to prevent making copies). I even used to record movies or shows from Hulu by connecting my two computers and recording on the 2nd one. That was a great device. I still have the original box and accessories.
I bought it to digitize my vinyls via USB on my computer. It comes with a free editing software to help remove scratches, pops, clicks and background noise.
I used to have a graphic equalizer with a small LED display and I miss it a lot when I listen to music.
Now you can get a much cheaper alternative but some are pretty expensive.
There are more and more of those LED spectrum Analyzer available now and most come as DIY kits.
I bought the small one and I love it! Thanks for the tip!
I connected it to my TV since I watch it more than I listen to music right now so I get to see it in action every day.
