The MC-1.2 enables for the first time bi-directional conversions between USB audio streams and digital audio signals like AES3, AES3id and S/P-DIF. Therefore, the box does not only offer digital audio outputs, like most of the others, but also a full set of digital audio inputs for AES3, AES3id and S/P-DIF with BNC, RCA and optical interfaces. Signals received at the USB port are converted to five digital audio outputs simultaneously, which allow the connection of multiple receivers at your computer. When selecting one of the digital audio inputs, the signal received is converted to an USB audio stream and sent into your computer. Both signal paths are able to work at the same time, presupposing equal sampling rates. This enables e.g. the simple connection of effect processors to your computer or the use of recording-equipment, whereat monitoring of recorded signals is possible through the computer during recording.

High-End DACs or music servers often use BNC interfaces for S/P-DIF transfers, which is from an electrical point of view surely the best choice. With the MC-1.2, you can convert USB audio streams of every PC or laptop into the S/P-DIF format and output that through BNC interfaces to drive High-End equipment easily. This can be done while having four further outputs available to feed e.g. digital headphone amplifiers or other devices for convenient listening.

The MC-1.2 is a high-performance USB audio interface which converts from USB to AES3, AES3id and S/P-DIF signals, and vice versa.
