Audio Encoder for up to 16 digital stereo channels
or up to 8 analog stereo channels


The Qbit Q9X-E Audio Encoder sets standards for high quality audio encoding.

Based on the proven Qbit platform, it provides highest signal quality, best build quality and service without compromise. Customers around the world trust our market leading Audio Encoder.

Either up to 16 digital or up to 8 analog stereo audio channels can be encoded simultaneously. They can then be output as MPEG-2-compliant DVB transport streams or elementary streams via the IP interface. Several configurations are available to flexibly adapt the audio input configuration to the network requirements. Each channel can be configured individually.

The Q9X-E Audio Encoder can be conveniently managed via the integrated web interface with all common web browsers. The device can also be monitored and managed via SNMP or REST-API.

The unit is built in a compact 19’’ 1 U housing. The transmission of ancillary data and switching contact information (GPIO) is possible with the default interfaces. Optionally, a second data interface can be used as a backup function.

The Q9X-E is CE and RoHS compliant to meet the demand of users worldwide.

The basic unit is licensed for one audio encoder channel and the functions RDS and GPIO. Further channels and options are possible.

If you need more than 16 stereo channels, our Q8V appliance is the best choice.
