USB Audio
The USB Audio port on the S0 allows live audio
transfer between the mixer and a computer
or other compatible USB Audio device. This
effectively provides an additional input channel
to the mixer that can be routed to channels 5-8,
and a simultaneous output which contains the
audio from either the PGM or REC output. The
stereo USB Audio port is configured to run at a
sample rate of 44.1 kHz with 16 bit samples in
both directions.
No special software drivers are required; simply
connect a standard USB cable between the S0
and the computer. To check that a connection
has been made, open the Device Manager in
Microsoft Windows®, and locate the Sound,
video and game controllers section. A new entry
should appear “S0 USB Audio”.
USB Audio Output from the S0
The USB Audio output from the S0 is, by default,
encoded from the audio signal on the REC bus. It
is possible to change this so that the USB Audio
output is encoded from the audio signal on
the PGM bus. This involves changing 2 jumper
settings that are located on the PCB directly
under the front panel on the S0. Contact Sonifex
Technical Support for details on how to change
these settings.
Once the USB Audio port is connected to a computer, it is possible to listen to and record
the audio. Microsoft Windows® identifies the USB Audio input from the S0 as an additional
Line input recording device with the device name S0 USB Audio.
USB Audio Input to the S0
Microsoft Windows® identifies the USB Audio output from the computer as an additional
Line output playback device with the device name S0 USB Audio. The USB Audio input to
the S0 is decoded and routed to channels 5-8. The USB Audio input on these channels is
selected when the INP1/INP2 button is illuminated amber. It might be necessary to change
the configuration options to enable this input to be selected. The USB Audio input can
also be used as a pre-fade input such that the audio is automatically routed to any of the
monitor and headphone outputs with AUTO CUE/PFL selected once audio is present.
