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.
Introduction Peripheral MUTEC Products Optical cables in different lenghts from 0.5 m to 20 m for S/P-DIF and ADATTM transfers. MW-02/19, Mounting plate to install two MC products side by side into one unit of a 19” rack. MW-03/19, Set of two rack mounting angles to install one MC product on the rear side of a 19” rack. MW-05/19, Set of two rack mounting angles to install one MC product frontally into one unit of a 19” rack. For all peripheral products please have a look on our website: www.mutec-net.
Installation Content of the Box Your MC-1.2 was packed carefully. Nevertheless we recommend to check the content directly after opening the package: 1 x MC-1.2 1 x Power cable 1 x USB cable 1 x Manual If there are any damages visible, please refer to Safety Instructions and Warranty Regulations for further details. Placing the Device The unit should be set up as closely as possible to the devices to which it will be connected with to avoid excessive cable lengths.
Installation General Recommendations for Interface Wirings AES/EBU & S/P-DIF Interconnections When working with XLR-based AES3/-11 or RCA-based S/P-DIF audio signals at high sampling rates , well-shielded electrical cables are mandatory to avoid increased radiation! Standard cables are normally useable for sampling rates up to 50.0kHz.
Control Elements and Terminals MC-1.2 Front Panel 1 2 3 4 5 6 7 1 »POWER« This red LED lights up when the unit is switched on with the rear panel power switch. 2 »MENU« Use this key to access the different menus. 3 »SELECT« Use this key to select a function within a specific menu. 4 »AUDIO IN« This menu allows to select the one of the four, respectively five digital audio inputs/formats for converting into an USB audio stream to send it to your computer or laptop.
Control Elements and Terminals 2 »AES3id OUT & S/P-DIF OUT« The AES/EBUid output on the top transmits an unbalanced electrical digital audio or blank-frame signal in compliance with AES3id-2001 (revision of 1995) or AES11-2003 (revision of 1997). The S/P-DIF output below transmits an unbalanced electrical S/P-DIF digital audio or blank frame signal in compliance with the IEC 60958 standard. The interface impedance of both outputs is 75 Ω (BNC connectors, female).
USB Driver Installation & Windows Settings MUTEC USB Audio Class 2.0 Driver for Windows General Description When connecting your MC-1.2 to a Windows computer, you have to install the USB Audio Class 2.0 Driver for Windows available on our website. This must be carried out regardless of the sampling rates of the transfered audio streams. Attention Install the driver first before connecting the MC-1.2 to your Windows computer! No driver installation is necessary when using the MC-1.
USB Driver Installation & Windows Settings Driver Download and Installation Procedure Please go to our website to download the MUTEC USB Audio Class 2.0 Driver for Windows as follows: www.mutec-net.com > Products > USB Interfaces > MC-1.2 > Downloads Or for direct access type in the following URL into your browser: http://www.mutec-net.com/product_mc-12.
USB Driver Installation & Windows Settings Windows Settings After installation of the MUTEC USB Audio Class 2.0 Driver for Windows is successfully completed, you can connect your MC1.2 to one of your computer’s USB ports by using the USB cable included in the scope of delivery. Switch on your MC-1.2 and it should be automatically recognoized by your computer‘s operating system. Attention The direct interconnection between your MC-1.2 and your computer is best with regards to signal perfermance.
Operation In the »Playback« tab select »MC-1.2« from the list of available devices and click »Properties«. Click on the »Advanced« tab and select under »Default Format« the entry »24 Bit, 19200 Hz (Studio Quality)«. Under »Exclusive Mode« check that the two tik boxes are selected. Click »OK« to store your settings. General System Operation Operating the MC-1.2 is very easy! The device is fully operated using the two keys on the front panel.
Operation Operation of the MC-1.2 USB Operation After connecting the USB cable coming from your computer, laptop or music server to the MC-1.2‘s USB port, an audio stream sent from the source will be received and converted straightforward to all digital audio outputs. No further adjustments are necessary for that general operation of your MC-1.2. That even works if the device is not connected to the mains supply, called: USB bus-powered operation.
Operation »USB POWER« This LED indicates USB bus-powered operation of the MC-1.2. STATUS AUDIO INPUT »ORIG« This LED indicates the SCMS-encoded status of a received S/P-DIF audio signal as »original source«. »1st« This LED indicates the SCMS-encoded status of a received S/P-DIF audio signal as »1st copy«. »NONE-PCM« This LED indicates that the received S/P-DIF audio signal is of »none-standard PCM« coding. like e.g. AC-3, MPEG, etc.
