Q560 IP Audio Codec

Details

The Q560 is an Audio Codec for up to 4 bidirectional stereo channels (digital AES/EBU) or 2 bidirectional 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. Available Interfaces are IP, ISDN, E1 and X.21. Several ordering options are available to adapt the audio input/output configuration to the customer´s requirements in a flexible way.
