Details

The Qbit Q561-DVB IP Audio Decoder 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.
 
Up to 8 digital stereo audio channels (or 4 analog channels) can be encoded simultaneously. They can then be put out as MPEG2 compliant DVB transport streams via IP or ASI interface.
Each channel can be configured individually (e. g. compression algorithm, bit rate, stereo mode, etc.).
 
If more than 8 stereo channels are required, it is possible to cascade up to 4 Q561-DVB in order to create a transport stream with up to 32 audio channels.
 
The transmission of ancillary data and switching contact information (GPIO) is possible with the default interfaces.
