Configuration of the Sample Rate
The sample rate of the balanced audio interface can be configured individually.
•
The default sample rate is 48.0 kHz.
•
The sample rate can be configured in the
Config.txt
file of the extender module with the balanced
audio CPU module. Therefore, the respective parameter
SRC
has to be entered into a new line. If there
is not entered any parameter, the sample rate 48.0 kHz will be used. The following additional sample
rates can be configured:
−
32.0 kHz (enter

in
Config.txt
file)
−
44.1 kHz (enter

Compatibility
Extender modules with balanced audio interface are compatible to extender modules with digital audio
interface regarding the transmission of the audio standard 2-channel PCM.
•
The compatibility shall be applied to the add-on module digital audio and the extender modules of the
481/491 and 483/493 series.
•
The compatibility is regardless of the input or output side, this means that a digital audio input is
compatible to a balanced audio output and vice versa.
