M-Audio CO3 Coaxial/Optical/SPDIF/AES-EBU converter Coaxial, Optical, AES/EBU ConverterThe CO3 is an AES/EBU, S/PDIF, optical converter that features simultaneous conversion in all directions and an SCMS management system.FeaturesConverts between AES/EBU, S/PDIF Coax, and TOSlink format digital audio streams.Three inputs: AES/EBU, S/PDIF Coax, and TOSlink.Three outputs: AES/EBU, S/PDIF Coax, and TOSlink.Source button determines which input is the audio source (master), the other 2 inputs are then ignored.Source input is converted to all 3 output formats simultaneously.SCMS (Serial Copy Management System) button sets copy protection, pass-thru, no copy protection, force "original," or force "1st generation."Supports sample rates up to 100kHz.Built-in jitter correction1/3 rack sized chassis.All audio ports are on rear of chassis.Source button, SCMS button, Power button, and LEDs are located on the front panel.3 LEDs indicate which input is currently the master.4 LEDs indicate the SCMS mode.1 LED indicates the validity of the incoming audio stream.9VDC wall-wart powered.
