The USB-interface (USB 1.1) allows for the mixer
to be used as an audio interface. In other words,
audio recording and playback can be done
through a connected computer with Windows
Operating System (Windows XP, Vista, 7, 8) and
Apple Macintosh OS 10.5 or higher. Separate
drivers are not necessary for the installation.
Once connected to a suitable USB port on your
computer (USB 1.1, USB 2.0), the drivers are auto-
matically installed. The audio interface is detected
as "USB Audio CODEC" interface on both Windows
and Apple Macintosh computers.
The recording signal consists of the sum signal
which is sourced after the master level control and
the max level control, and is therefore dependent
on it. Audio playback is via the line channel INPUT
5. This requires the switch 45 on the back panel to
be pressed (USB).
