AES Audio Embedding Module with AES Output

The SMX6811N(S)8/SMX6812N(S)8 is an 8-channel AES audio embedding module. All modules support 4 pairs (8 channels) of AES audio embedding. The user can choose either input audio or other audio synthesized by the system and set them into two groups via the menu and embed them into any of the two groups out of the four audio groups.
Each module has its distinct feature as follows:
The SMX6811N8 has 4 pairs of unbalanced AES inputs;
The SMX6811NS8 has 4 pairs of unbalanced AES inputs and audio tracking;
The SMX6812N8 has 4 pairs of balanced AES inputs;
The SMX6812NS8 has 4 pairs of balanced AES inputs and audio tracking;
