OUTPUTS
MPX OUTPUTS: the MPX signal is including a mono audio (LL+RL), stereo audio (LH-RH), 19 kHz stereo pilot tone and RDS data (Radio Data System),
which can be sent to the FM transmitter using a good quality.
In addition, other services such as Subsidiary Communications Authorization (SCA) channels may be adding to the MPX signal from external source
like by AUX1 and AUX2 which are modulated onto higher subcarriers, 67 kHz and 92 kHz.
Here we have three MPX outputs, one of them is a digital MPX signal formatted for
interconnection using AES/EBU codec at 192 kHz sample rate. MPX over AES is carried
on AES EBU-2 or DANTE-2 output channels (see ADVANCED OUTPUTs / part G).
In most applications only RDS data is transmitted in addition to the audio program
which is carried at 57kHz. But there are some applications that require a wider
spectrum for other services such as Subsidiary Communications Authorization (SCA)
channels, SCA-1 and SCA-2 may be generated which are modulated onto higher
subcarriers, 67 kHz and 92 kHz. however, Our DIGITAL MPX signal is 96kHz spectrum.
AXEL codecs of DIGITAL MPX Over Internet Protocol provide a very low latency
transmission between 5 and 35ms.
