About Audio Levels
Professional audio equipment has much higher levels than consumer equipment:
a 0 VU reading corresponds to +4 dBu. Connecting a professional +4 dBu device
to a consumer audio input (-7 to -8 dBu) may produce overloading, whereas the
output of a consumer device probably does not have sufficient power to drive a
professional audio input. With consumer and semi-professional audio equipment,
a VU reading of 0 dB is typically referenced to -10 dBV, which is equivalent to -7.78
dBu.
Setup Tab Screen
Click on the Setup tab to view and make changes to the card name or to restore
card settings to factory default values.
Card Name - By default, this field is pre-populated with the card name
OG-12G-AMA. You can change the card name by editing the text in the Card
Name field.
NOTE: Changing the Card Name in the Setup tab also changes the name of the card in
the DashBoard tree view.
