SIP connectivity in high density with 8 channel O/I in half 19!

With only ½ 19” and 1 RU it offers more than any other codec of comparable size: 8 channels in and out simultaneously, analog and digital on board. Thanks to its AES67 support it can manage even more simultaneous connections than that for an incredibly high connection density. It is a universal audio codec solution combining classic codec applications with routing, mixing, recording and live requirements. All that in a compact package powered by aixtream.

RTP and SIP are supported studio and for classical broadcasting applications, just like HLS, RTMP and IceCast for OTT streaming. DVB transmission too is available, and with our focus on cutting edge technology input and output via AES67 is of course also possible.
