Audio Encoder for up to 8 stereo channels (digital AES/EBU)
or up to 4 stereo channels (analog and digital AES/EBU).


The Qbit Q561 IP 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 IP Audio Encoder.

Either up to 8 digital or up to 4 analog stereo audio channels can be encoded simultaneously. They can then be output as MPEG-2-compliant DVB transport streams via the IP or ASI interface and as 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 Q561 IP 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.

The unit is built in a compact 19’’ 1 U housing. It is DSP-hardware based and highly energy efficient (< 2 W per stereo channel). Basic setup and status monitoring can be done via the control panel and the LC display on the front of the device. Users can select the audio quality by adjusting the codec, bit rate and sample rate via the integrated web-server.

Optionally, a second data interface can be used as a backup function. If more than 8 stereo channels are required, you can cascade multiple Q561 devices and create a Transport Stream with up to 40 audio channels. The transmission of ancillary data and switching contact information (GPIO) is possible with the default interfaces.

The Q561 is RoHS compliant and CE certified to meet the demand of users worldwide.
