6.8.4 AES/EBU Audio Input
The PTX-PRO will only provide digital audio when operating in
digital mode.
In digital mode, the PTX-PRO receives a digital signal and routes
the data to the MPEG encoder and then to the COFDM
modulator. The PTX-PRO audio switching circuitry connects the
output of the MPEG encoder to the AUDIO connector.
When configured for digital audio output (AES/EBU), the MPEG
encoder provides two paired channels of digital data (+ and -), or

In digital mode, the audio channels are referred to as Audio A
