I am looking to purchase either AudioBox usb 96 or Audiobox iOne. I want to record live using simultaneously two inputs simultaneously. The first is a standard xlr microphone level input, the second is the "recording out" line from a Yamaha powered mixer. The Yamaha manual spec defines this as: Unbalanced, Nominal impedance 10k ohms, nominal output level -10dbv (316mv), max before clipping +10dbv (3.16v). Would the AudioBox usb 96 be OK for this or would the Audiobox iOne be better? I would prefer the 96 because it offers the option of two mic level inputs.
