The USB 2.0 class-compliant driver provides two channels of 48k/24-bit audio from the computer to the Axe-Fx II,
up to four channels from the Axe-Fx II to the computer, and two-way MIDI-over-USB. All features can be used
simultaneously. Note that even though the Axe-Fx II is fully class-compliant, you must still install the drivers found
at http://fractalaudio.com/support .

Audio and MIDI ports (shown in the top dotted-outline boxes above) have different names on different systems. In
many applications, you can also assign “friendly names” to audio and MIDI ports.
Two Simultaneous Channels of 48k/24-bit Audio from the Computer to the Axe-Fx II
Two output channels allow audio to be sent from the computer to the Axe-Fx II where it can be processed by the
unit or simply played back to OUTPUT 1.
To process computer audio with the onboard effects, set the
MAIN INPUT SELECT
(p.
) to “USB.” Computer
audio will be routed to the grid INPUT. This allows you to re-amp a dry track, for example, or use the Axe-Fx II to
process other audio or plugin tracks. It is possible to simultaneously record the processed output on the computer
using the Axe-Fx II audio inputs (0/1).
To pass unprocessed computer audio through the Axe-Fx II, set the
MAIN INPUT SELECT
(p.
) to “ANALOG
(IN1)” (the default setting) or “SPDIF/AES.” Computer audio is mixed with the regular output of the Axe-Fx,
allowing you to play along with backing tracks or use the Axe-Fx II as a high quality “soundcard.”
