Introduction Thank you for purchasing the CO3™ Digital Audio Format Converter from 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.

Front Panel 1. Source selection LEDs. These LEDs indicate which one of the three input jacks is selected as the source of incoming digital audio. Only one of the LEDs is lit at a time. 2. Source selection button. This pushbutton selects one of the three input jacks to be the source of incoming digital audio. Repeatedly pressing this button will cycle through the three available selections. 3. Source Valid LED. This LED indicates the state of the currently selected source input.
PAGE 4
Once valid incoming data is detected, the digital data from the source input is converted to three digital audio outputs: 1. Optical S/PDIF, labeled "TOSlink," is output via the TOSlink connector. 2. Coaxial S/PDIF, labeled "S/PDIF," is output via the RCA jack. 3. AES/EBU, labeled "AES/EBU," is output via the male XLR jack.

in the "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).

source to the output sources with no modification. Pass-Thru is available in all modes except when the input source is AES/EBU -- because an AES/EBU input carries no SCMS data, there is nothing to pass through when AES/EBU is selected as the input source. SCMS "None" Mode When SCMS mode is set to None, the outgoing SCMS bits are set to indicate that there is no copy protection asserted (the material may be copied).

S/PDIF streams for you. Input Source Modes Depending on the type of input selected, the CO3 functions will differ according to what conversions can be done, and which cannot. The SCMS mode settings behave the same way for both TOSlink (Optical S/PDIF) and S/PDIF (Coaxial) source signals, and whichever is chosen as the source, that signal is output to both the optical and coaxial S/PDIF output jacks.

Mode Summary Here’s a quick reference table for your convenience: SOURCE SCMS MODE TOSlink Out S/PDIF Out AES/EBU Out TOSlink Pass-Thru (default) Original 1st Gen None No conversion (exact duplicate) SCMS forced to original (master) SCMS forced to 1st Generation (copy) SCMS forced to "no copy protection" No Conversion (exact duplicate) SCMS forced to original (master) SCMS forced to 1st Generation (copy) SCMS forced to "no copy protection" True signal, SCMS discarded Invalid Invalid Invalid S/PDIF
