Maybe this just adds a bit more confusion or maybe it makes it easier on the wallet, but JuicedLink has added 4 additional preamps to it's lineup. The new models vary with number of XLR inputs, with or without Phantom Power, and some with or without Assist features like Headphone monitoring or visible audio meters. Some cameras already have Headphone monitoring and Audio Meters available like the new Nikon D600, so you'll just be looking to get a smaller less expensive JL Preamp. Check them out at the Juicedlink website (Click Here).
