Details
The Q561 is an Audio Encoder for up to 8 stereo channels (digital AES/EBU) or up to 4 stereo channels (analogue and digital AES/EBU). Compact (19" 1U housing), highly energy efficient (< 2W per stereo channel in AES/EBU version), DSP-based hardware. Streaming of elementary streams over IP, or generation of DVB-compliant MPEG-2 transport stream, output via IP or ASI. Several ordering options are available to adapt the audio input/output configuration to the customer´s requirements in a flexible way.
