Almost any FTA satellite receiver can tune to alternate audio PID's (i.e. channels) which exists on some video channels. Pressing a key on the receiver's remote control labelled "Audio" or "Lang" when tuned to the channel in question will display a list of audio PIDS to choose from and are typically associated with languages such as English or Spanish. Most receivers also support tuning the Left channel only, Right channel only or both channels on stereo PID's.
On this particular channel, there are only 2 audio PID's but each of these are stereo with the left and right channels also being used to carry audio for a specific channel which provides a total of 4 possible audio tracks.
