Core Sound — M-Audio's CO3 Format Converter & SCMS Controller and AES-EBU, S/PDIF & AC-3 cables

We've had many people ask how the CO3 differs from our CO2.

The CO3 has a single data path, while the CO2 can provide both single and bi-directional data paths. Both the CO3 and CO2 can select between their inputs; both always have their outputs outputs active simultaneously.

The CO3 has three inputs: S/PDIF optical, S/PDIF coaxial and AES/EBU XLR. The CO2 has two inputs: S/PDIF optical and S/PDIF coaxial.

The CO3 has three outputs: S/PDIF optical, S/PDIF coaxial and AES/EBU XLR. The CO2 has two outputs: S/PDIF optical and S/PDIF coaxial.

The CO3 converts data format as well as physical format. The CO2 doesn't do any data format conversion.

The CO3 controls SCMS while the CO2 doesn't.

The CO3 is larger than the CO2.

Both the CO3 and CO2 can drive and be driven by the signals on Sony's current portable DAT recorders' 7-pin jacks.
