The OCTO Sr is a cascadable DSP audio processor which has 4 audio I/O card slots for fully flexible I/O configuration. Up to 12 x OCTO Sr units can be cascaded via 16 audio channel DIGILINK bus with CAT5/CAT6 cable. For even larger installations, the OCTO Sr is capable of handling with possible configuration up to 32x32 CH I/O's.

The digital OCTO-Link, which allows each port to have 2 audio channel IN and 2 audio channel OUT in digital format simultaneously, providing a wide variety of remote digital I/O expansion and remote control for Xavtel RWD-series. The OL-AMP, the Low-Z digital amplifier also provides the excellent audio quality for a centralized multi-room of applications. The connection is also done with standard CAT5/CAT6 up to 820ft.(250M). The OCTO Sr features 8 programmable and scalable knobs that can give direct control to any parametric control.

The OCTO Sr incorporates a powerful DSP such as logic blocks, custom components, page controller, ambient noise compensation, room combiner, ANR(Acoustic Noise Reduction) etc.. It also allows for optional AEC channels for both analog and VoIP teleconferencing system which accept and send audio stream right from the TCP/IP network. Logic I/O, RS485, RS232 or Ethernet can also be available over 3rd party control.
