    CO3 Manual CO3-111201 version: Table of Contents Introduction ..........2 Features .
  • Page 2: Introduction

    M Audio. The CO3™ converts between AES/EBU, S/PDIF Optical, and Coaxial S/PDIF digital formats. A precision instrument, the CO3 does more than just convert an unbalanced signal to balanced and vice versa. The CO3 gives you several options to manage the copy protection bits present in S/PDIF signals as well as creating the SCMS (Serial Copy Management System) bits required when converting AES/EBU to S/PDIF.

    3. AES/EBU, labeled "AES/EBU," is input via the female XLR jack. Only one of the inputs to the CO3 is active at any time and the user selects this input, called the "Source" input, from the front panel. Once selected as the source, the input is constantly analyzed by the CO3 to determine if its digital audio stream is present and has a valid format.
  • Page 4: Installation And Setup

    With the CO3’s power button in the outward "off" position, plug the appropriate end of the power adapter into the CO3’s power jack, and the other end into a live wall socket or power strip. Leave the CO3 powered off until all connections are made.

    "Power" button. The CO3 will always power on with TOSlink Optical S/PDIF as the source selection, and "Pass-Thru" selected as the SCMS setting. From the front panel of the CO3, select the input source setting that matches the format of your input source. Optionally, set the SCMS mode to its desired setting (more specific information about this is coming later in the manual).
  • Page 6: Scms "None" Mode

    Therefore most receiving units will accept this material. Similar to "None" mode, if the source is coaxial or optical S/PDIF, then the CO3 actually strips the SCMS material out of the incoming stream and replaces it with bits that indicate original material.
  • Page 7: Input Source Modes

    Therefore, Pass-Thru mode is not available from the front panel when AES/EBU is selected as the source. In all three SCMS modes, the data bits coming into the CO3 AES/EBU input are directly copied to the AES/EBU output jack unaltered, and the CO3 does a true conversion to the two S/PDIF format output jacks.
