|| I own the sister model of this device [M-Audio FastTrack] and it was a phenomenal addition to my home studio. The MobilePre is no different. I often record in stereo, so having dual XLR inputs with a volume knob dedicated for headphones makes the process work smoothly. Being able to independently mute both XLR inputs is a plus, because this allows me to set the appropriate mic volume, using the corresponding knob, while pressing the 'Ch.1 / Ch.2' mute buttons without reversing the initial volume knob position. [Great way to test the sound level for each input.]
|| While this device is no longer supported by M-Audio, If you run across this gem on Amazon, ebay or craiglist, I would adamantly urge you to purchase it. I believe that working with 'old tech' is the best way to learn how to maximize your abilities as an artist, because it forces you to learn every little aspect of the device - which drastically increases your skills with it.
