\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> INTRODUCTION Thank you very much for purchasing the MC-3+ Smart Clock, Synchronizable Digital Audio Master Clock Generator, from MUTEC ! General Description The new MUTEC MC-3+ Smart Clock is especially designed to improve the acoustical quality of digital audio devices in two ways: At first by clocking external devices with ultra-low jitter Word Clock signals and secondly by aggressively re-clocking incomin

Refer to the OPERATIONS chapter for more information. 3 »SELECT« Use this key to select a function within a specific functional menu.
CONTROL ELEMENTS \\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> For a full list of all Word Clock, AES3 and S/P-DIF clock rates that can be generated, please refer to the »Generatable Word Clock Frequencies« and »Generatable AES3 and S/P-DIF Frequencies« sections in the APPENDIX chapter.
\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> INSTALLATION Content of the Box The unit was packed carefully. Nevertheless we recommend to check the content directly after opening the package: 1 x MC-3+ Smart Clock 1 x Power cable 1 x Manual The condition of the packaging material and the device should be checked carefully additionally. If there are any damages please refer to SAFETY INSTRUCTIONS and WARRANTY REGULATIONS.

Plug the T piece with its center connector into the input of the receiving device. Then, connect the cable coming from the Word Clock output to one of the lateral connectors, and the other connector of the BNC-T piece to a 75 Ω resistor forming the BNC termination.
\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> GENERAL OPERATION Selecting Function Menus and setting Functions Operating the MC-3+ SMART CLOCK is very easy! The device is fully operated using the two keys at the front panel. 1 Pressing the »MENU« key toggles between different basic function menus. 2 Pressing the »SELECT« key activates individual functions within one function menu.

Shut-Down of Outputs All digital audio outputs are shutdown during function selection! After a function is finally selected and the corresponding LED lights constantly again, the digital audio outputs are activated for signal transfer. ! User Settings Remain All user-specific function settings are available furthermore when power is restored.
