The DSLR Film Noob is at it again, finding versatile gear at affordable prices. Today he shares his findings about the ART USB Dual Pre, which allows XLR and 1/4" mic inputs, adjustable volume, phantom power, USB connectivity and lots more. For a reasonable $79, this is a great deal. The caveat is that it's not made to connect to any kind of camera rig, but Deejay shows a simple hack (he drilled a hole in the case) to remedy this.
I'm still using my XLR-PRO converter box, but the ART Preamp is light years past the XLR-PRO in features and at almost half the price. If you need something like this (which is probably closest to a $299 Juicedlink CX231), it's definitely worth your time, especially if you don't mind the easy mod to make it mountable.
