Audio channels can be linear, or compressed (encoded / decoded at various quality levels) to optimize the data link. Data link capacity not occupied by audio can be used to transport data. The MPX not only moves audio between stations, but also routes it to the required destination at each station. The MADI and E1/T1/J1 modules offer complete flexibility. They handle input / output, input only, output only, mic and line level analogue audio, AES/EBU and SPDIF digital formats, as well as AES-10 MADI multi-channel digital audio. They also provide optical I/O to facilitate connection with the most frequently used equipment and systems.
