Introduction
Thank you very much for buying the MC-1.2, a bi-directional USB & Digital Audio Interface, from MUTEC!
General Description
The MC-1.2 is a high-performance USB audio interface which converts between USB, AES3, AES3id and S/P-DIF signals. It
enables for the first time bi-directional conversions between USB audio streams, AES3, AES3id and S/P-DIF signals. Using latest
USB streaming technologies, low jitter audio clocks, ultra-low noise power supplies and circuit designs, the MC-1.2 regenerates
and improves USB audio streams with embedded clock rates up to 192.0kHz.
Various operation modes enable the use of the unique MC-1.2 in many applications. Signals received at the USB port are con-
verted to five digital audio outputs simultaneously, which allows 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 can work at the same time. This enables e.g. the simple connection of effect processors to your computer.
The MC-1.2 also works as isolator to decouple noisy computers or music servers from your audio equipment. Based on the abil-
ity 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.
The already unbeatable flexibility of the MC-1.2 is increased by operating the unit with its internal power supply for stationary
use or alternatively powered through the USB port during e.g. mobile events.
