Is the iMic a digital input? Is it 24-bit, 48KHz? (Mac)
The iMic is an A/D (analog to digital) converter, and a very good one for the price. It will convert your analog input signal to digital, and vice versa on output. The iMic itself does all internal processing at 24bit resolution but the Mac OS currently has a more narrow range of options, topping out at 16bit/48KHz. Third party USB ASIO drivers will allow the iMic to support up to 24-bit resolution.
