Ultimate Interconnectivity
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.

USB Signal Regeneration and Improvement
It is known, that USB interconnections, respectively the transfer of digital audio via USB let most of the DACs not sound best. That actually applies also for higher-priced DACs. Using the digital inputs at DACs often results in a better sound. At this point, the MC-1.2 comes in and may help to convert your USB audio streams best possible and to connect your DAC via its digital audio inputs correctly. Additionally, by using latest USB streaming technologies, low jitter audio clocks and ultra-low noise circuit designs, the MC-1.2 is able to regenerate and improve the converted audio signal in a way that connected DACs usually sound better as when fed directly through their USB interfaces.

Based on the MC-1.2's ability to work not only USB bus-powered, but also to use its own internal power supply, an isolation between the different power supplies for the digital audio and the USB part of the circuit is the result. To further improve this separation, the different areas of the circuit are supplied independently from each other by ultra-low noise power sources with carefully dimensioned external circuitries. Thereby, the transfer of distortions from the USB stream into the digital audio part can be reduced to an absolute minimum. That helps to improve the audio performance of the converted digital signals significantly.

Usability in Studio, Home and Live Event Environments
The already outstanding flexibility of the MC-1.2 is additionally increased through the ability to run the unit with its internal power supply for stationary use, or alternatively powered only through the USB interface during e.g. mobile events. Both states are displayed by LEDs on the front panel.

The MC-1.2 comes in a matt-black, rugged steel case with anodized aluminum front panel. Regarding the front panel, you can choose between an aluminum- or black-colored version during purchase. Custom-designed case feets, which include soft rubber rings to prevent unneccessary vibrations, are standardly supplied to use the MC-1.2 as desktop device. For rack-mounting, the feet must be unscrewed and optional rack angles are mounted on the right and left hand of the case.
