Q572 is a DVB-S2 audio satellite receiver for up to 8 stereo channels (digital AES/EBU) or 4 stereo channels (analogue and digital AES/EBU). Besides the audio signal up to 8 data channels are available via RS.232 or IP. The IP data output or an optional ASI output can provide received MPEG-2 Transport Stream. Due to its DSP-based hardware, Q572 is compact (19" 1U housing) and highly energy-efficient (< 2W per stereo channel). Several ordering options are available to adapt the audio output configuration to the customer´s requirements in a flexible way.
