S2-3 Parity Error

 – When set to on will cause the switcher to switch as per S2-1 setting for a 

parity error in the incoming digital audio stream.  
 

S2-5 CRC Error

 – When set to on will cause the switcher to switch as per S2-1 setting for CRC 

error of incoming digital audio stream.  
 

S2-6 Audio Bit

 – When set to on will cause the switcher to switch as per S2-1 setting if the digital 

audio stream audio bit is set to 0 which denotes non audio payload data. When this setting is set 
to on the analog output is muted.  
 

S2-7 Non PCM Audio 

– When set to on causes the switcher to switch as per S2-1 setting when 

non PCM audio streams are detected such as Dolby E and AC-3 formats. To use the switcher 
and digital DA for non PCM audio formats set S2-6, S2-7, S1-4 and S1-5 to off position. This will 
allow the AES-402 unit to act as a manual digital audio switcher for non PCM audio streams and 
defeats the silence sensor which cannot be used in the is mode of operation.
