54 USB
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
and is sourced before the master level control and
the max level control, and is therefore indepen-
dent of it. Audio playback is via the line channel
INPUT 1. For this, the switch 55 must be pressed
on the back panel (USB) and the switch 8 (LINE)
on the front of the unit should not be pressed.
55 USB / LIne

interface (54) is selected, if not pressed, the line
input (51) is selected as the signal source.
