use with a Mac or PC computer.

driver is installed. The latest ASIO driver, along with install
instructions, is available for free at www.sounddevices.com/support/downloads.
See the MixPre-3M’s Downloads page.
To work with the USB audio from a host computer, it is necessary to route the
USB 1 - 4 sources appropriately. Should you want to mix the USB audio from
the host computer with live audio from the MixPre-3M’s inputs to the LR bus,
use the channel screen and select input source.
The MixPre-3M is capable of recording and streaming audio to a USB host
simultaneously. It is also capable of recording the USB audio stream out of a
computer directly to its SD recorder. This is an amazingly useful feature for
recording any computer-based audio.
See the table below detailing the MixPre-3M’s channel to output assignments.
