INTRODUCTION
Thank you for purchasing a MC-3 SMART CLOCK or MC-3.1 SMART CLOCK SD,
Digital Audio & Video Sync Master Clock Generator from MUTEC GmbH.
Please keep this manual for future reference!
General Function Description
SMART CLOCK and SMART CLOCK SD generate different clock signals for
synchronization of digital audio and SD video devices such as hard-disk
recorders, A/V workstations, digital mixing consoles, AD/DA converters,
musical instruments and sound cards. Simultaneous use of all available
clock signals enables each device in the recording studio to be individually
synchronized. In addition, different clock rates of all audio-related clock
signals can be simultaneously output. Thus, new devices with higher clock
rates may be integrated into an existing studio set-up without difficulty. It
is also possible to supply various workstations in the same room with differ-
ent clock rates.
MC-3 SMART CLOCK offers 7 basis Ultra low-jitter Word Clocks from 32.0kHz
up to 192.0kHz, which are then independently distributed to four clock
output pairs with multipliers x1, x2 and x4 for a maximum clock rate of
768.0kHz. For the synchronization of older digidesign ProTools™ systems,
the respec-tive Word Clock frequencies can be transferred as Word Clock x
256 (also called Super Clock). AES/EBU and S/PDIF (optical + coaxial) blank
frame sync signals are available from 32.0kHz up to 192.0kHz.
Every Word Clock output pair as well as the AES/EBU and S/PDIF outputs can
be set to a different clock rate, based on one common clock frequency.
MC-3.1 SMART CLOCK SD offers same audio clock functionalities like
MC-3 SMART CLOCK, but includes a standard definition (SD) video sync
reference generator supporting PAL or NTSC SD video sync signals as
Black + Burst or composite sync as well as the respective color bars. Two
additional video outputs are available on the rear side of the housing. Thus,
audio clocks and video sync references are all available at the same time to
synchronize complete audio/video facilities.
The design advantage of the SMART CLOCKs is its high-precision frequency
generator, from which all clock signals are simultaneously derived. As a
result, the individual clock signals generated are synchronized to each other
in phase, and hence feature the same frequency accuracy and time base!
The frequency generation is accurate to < ± 1ppm and thus complies with
AES 11, Grade 1, as well as broadcast specifications.
For larger equipment set-ups, which require more AES/EBU clock outputs
than are provided by the SMART CLOCKs, MUTEC offers a complementary
AES/EBU signal distributor which is called: MC-2. Therefore, please have a
look on our website: www.MUTEC-NET.de !

for a total of 15 different Word Clock frequencies.
Simultaneous output of different clock rates.
Frequency accuracy in compliance with AES11, Grade 1.
Generation of PAL/NTSC + NTSC b/w SD video sync signals as
Black + Burst, composite sync or color bar with MC-3.1 SMART CLOCK SD.
Phase-synchronized generation of S/PDIF and AES/EBU blank frames.
All adjustments are retained after power-down.
Simple, new user interface.
Built-in international power supply.
