Core Sound — M-Audio's CO2 Digital Audio Format Converter and S/PDIF & AC-3 cables

Core Sound is pleased to offer the M-Audio CO2 bi-directional digital audio format converter, digital audio cables and our exclusive CO2 battery cable!

The CO2 is the rare combination of value and utility. It's a wonderful little box that converts between digital audio's two physical formats: coaxial and optical. It doesn't care whether the data format is S/PDIF, AC-3 or whatever!

Do you have a DVD player that only has an S/PDIF coaxial (RCA) output and a digital receiver with optical (Toslink) inputs? Are you trying to dub from a DAT machine with S/PDIF coaxial outputs to another with S/PDIF optical inputs? Are you trying to interface an external A/D converter with S/PDIF optical outputs to your computer's audio card that only accepts coaxial? Is your D/A converter appear too far from your computer to use S/PDIF reliably? Do you need to convert optical to coaxial and, at the same time, also convert coaxial to optical? Do you need to feed two devices from one source?

If so, then the CO2 might be the answer to your prayers!

The CO2 is a compact and rugged tool that converts digital audio signals from optical to coaxial, and from coaxial to optical. Its clever 2-input/2-output design passes the original input signal through to one output jack, and the converted signal to the other output jack. This enables the CO2 to be used as a converter and/or repeater. (The CO2 does not manipulate SCMS in any way.)

And with its very low price, you can afford to use several in your studio!

CO2 features include:

Ultra-compact size: 3.5" x 2.25" x 1.2"
Converts optical-to-coaxial and coaxial-to-optical simultaneously
May also be used as a repeater for long cable runs
Two digital inputs: 1 Toslink (optical), 1 RCA jack (coaxial)
Push-button selects which input is the signal source
Two digital outputs, both always active: 1 Toslink, 1 RCA jack
Transformer-isolated RCA output jack prevent system ground loops

The CO2 is housed in a compact, rugged gray steel case and is roughly the size of a pack of cigarettes. It is powered by a 9 Volt "wall wart" transformer (included with the CO2), and draws approximately 300 milliamps. It can also be powered for more than two hours by a common 9 Volt alkaline battery via an optional battery cable. An LED glows when power is applied.
