I just picked up a Biamp Advantage ONE on eBay because it was dirt cheap. Here's the eBay description:
"Biamp Advantage One 8 Channel Rackmount Microphone Mixer. 8 Channels Of Xlr Microphone inputs, pads, two band eq with sweep and notchfilters. channel 8 has a broken gain control potentiometer otherwise fully functional."
So it's slightly busted and not equipped with 48V phantom power(but I should be able to replace the bad pot pretty easily).
Here's the thing, Biamp still sells an optional $125 module that provides +48 phantom power on all 8 channels. Question is, is the Advantage ONE a POS and should I just chalk it up as a loss and march out and get me the VTB-1, or is this a relatively OK piece of gear, and should I belly up the $$ for the phantom power module?
My guess is the VTB-1 is still cleaner. Although it does limit me to a single channel, I'm going to be recording myself and I'm only good for one instrument at a time anyway. And my vocals need all the help they can get.
