Installation Attention Before installing the unit the section Safety Instructions located at the beginning of this manual should be read carefully! Never expose the device and accessories to rain, moisture, direct sunlight, or excessive heat produced by radiators, heaters, or spot lights! Sufficient air circulation in the environment of the device must be ensured! Wiring the Interfaces Word Clock To allow for the synchronization of signals, the interfaces of all devices involved must be properly connected
Control Elements and Terminals 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. When interconnecting the optical S/P-DIF interfaces with plastic fiber cables, lengths of 10 meters should not be exceeded, to ensure reliable transmission of your digital audio signals.
Control Elements and Terminals 9 »CLOCK IN« This menu indicates the clock rates of the incoming clock reference or digital audio signal. DSD/DoP signals received through the USB interface can be identified with single (×64), double (×128) or quadruple (×256) clock rate.
Control Elements and Terminals 8 »USB I/O« This USB (Universal Serial Bus) interface receives or sends data streams in compliance with USB2.0. When connecting the MC-3+USB to a MS Windows PC, please install the provided USB2.0 Audio Class Driver for Windows at first on your computer. Refer to the »Installation of the USB2.0 Audio Class Driver for Windows« section on page 13 for further details (USB-B connector).
USB Driver Installation & Windows Settings MUTEC USB Audio Class 2.0 Driver for Windows General Description When connecting your MC-3+USB 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.
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-3+USB > 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 MC-3+USB to one of your computer’s USB ports by using the USB cable included in the scope of delivery. Switch on your MC-3+USB and it should be automatically recognoized by your computer‘s operating system. Attention The direct interconnection between your MC-3+USB and your computer is best with regards to signal perfermance.
USB Driver Installation & Windows Settings In the »Playback« tab select »MC-3+ Smart Clock USB« from the list of available devices and click at »Set Default«. after that the green check mark changes to the MC-3+USB entry. Click now on »Properties«. Click on the »Advanced« tab and select under »Default Format« the clock rate matching with your set-up. The optimum maner is the entry »24 Bit, 19200 Hz (Studio Quality)«. Under »Exclusive Mode« check that the two tik boxes are selected.
Operation General System Operation Operating the MC-3+USB is very easy! The device is fully operated using the two keys on the front panel. »MENU« Key Pressing the »MENU« key toggles between different basic function menus, usually between the vertical LED rows. »SELECT« Key Pressing the »SELECT« key activates individual functions within one menu by toggling between the LEDs of one vertical LED row. First press on »MENU« or »SELECT« key enables the last selected function within the last selected menu.
Operation Operation of the MC-3+ Smart Clock USB Main Function Menus The four main function menus provide access to all features of your MC-3+USB. Select the operational mode of the MC-3+USB via the »MODE« menu. This needs to be selected first. The factory default is »INTERN«. The »REFERENCE« menu allows selecting the individual inputs of the MC-3+USB.
Operation »EXTERN« – Selecting external Clock References External clock references can be selected when the MC-3+USB is set to »EXTERN« in the »MODE« menu. 1 2 3 4 INTERN WCLK 32.0 ×1 LOCK MAIN REF DSD 1–10.0M 32.0 EXTERN 1–10.0M 44.1 ×2 LOCK RE-CLK REF DoP 44.1 ×4 HOLD 64 48.0 ×8 AUDIO 128 RE-CLK MODE USB-PCM USB-DSD/DoP S/P-DIF OP AES3/11 S/P-DIF BNC AES3/11id REFERENCE 96.0 ×256 SC 176.4 48.0 ×256 WC 192.0 ×512 88.2 CLOCK OUT CLOCK MULTIPLIERS STATUS 256 96.

Operation Attention Using external clock references for audio re-clocking If you’d like to use a Word Clock or 10.0 MHz clock reference for the externally referenced re-clocking, you should make sure that particularly the phase noise near the carrier frequency (1-100 Hz range from the carrier frequency at 10.0 MHz) is very low. Because of the extremely low noise signal processing of the MC-3+USB, there is a risk of audibly worse signal performance if the externally applied clock reference is too noisy.
Operation Status Information The »STATUS« and »CLOCK IN« sections are strictly for monitoring the operational status of the MC-3+USB. They are not accessible for user adjustments via the keys. STATUS »LOCK MAIN REF« & »LOCK RE-CLK REF« The blue LED »LOCK MAIN REF« illuminates when the internal PLL circuit has detected a valid clock reference in the incoming clock, audio or USB stream signals. If the incoming signal is unstable or lost, the »LOCK MAIN REF« LED is not lit.
Operation Front Panel lock out + LED shut down When pressing both front panel keys together at one time, all LEDs will shut down except the »POWER« and »LOCK« LEDs. Additionally, the functions of both keys are also blocked to prevent unauthorized operation, which is important during e.g. live events. During that state of operation, pressing only one of both keys let every appropriate LED light according the device‘s settings as long as the key is pressed.
