AES Audio Embedding Module with AES Output

The SMX6811N(S)/SMX6812N(S) is a AES audio embedding module with AES output.
The modules all support 2ch AES audio embedding. The user can choose input audio or other audio synthesized by system and embed them into any audio group.
Each module has its distinct feature as follows:
The SMX6811N has 2ch unbalanced AES inputs as well as 2ch unbalanced outputs;
The SMX6811NS has 2ch unbalanced AES inputs as well as 2ch unbalanced outputs, and audio tracking;
The SMX6812N has 2 pairs (4ch) of balanced AES inputs as well as 2 pairs (4ch) of balanced AES outputs;
The SMX6812NS has 2 pairs (4ch) of balanced AES inputs as well as 2 pairs (4ch) of balanced AES outputs and audio tracking.
