Q9X-D

Audio Decoder for up to 16 digital stereo channels (digital AES/EBU) or up to 8 analog stereo channels (analog and digital AES/EBU)

Q9X-D

The Q9X-D Audio Decoder enables you to decode up to 16 digital stereo channels (or 8 analog ones). It is possible to decode elementary streams as well as DVB compliant transport streams. Input signals coming via IP can be handled and decoded.

Several ordering options are available to adapt the audio input / output configuration to the customer´s requirements in a flexible way.
