INTRODUCTION
Thank you for purchasing a MC-3.2 SMART CLOCK HD, Digital Audio & SD/HD
Video Sync Master Clock Generator from MUTEC GmbH.
Please keep this manual for future reference!
General Function Description
MC-3.2 SMART CLOCK HD is a unique, extremely high-flexible audio and
video sync reference clock generator.
The unit offers three simultaneously useable reference signal generators
in one box which generate standard definition (SD) bi-level video, high
definition (HD) tri-level video and the most common audio clock signals
like Word Clock, so-called Super Clock, AES/EBU and S/PDIF blank frames for
synchronization of digital audio and SD/HD video devices such as hard-disk
recorders, A/V workstations, video recorders, digital mixing consoles, AD/DA
converters, musical instruments. Simultaneous use of all available clock sig-
nals enables each device in the recording studio to be individually synchro-
nized. 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.
The SD bi-level video sync reference generator of MC-3.2 SMART CLOCK HD
supports PAL 24fps, PAL 25fps, NTSC 29.97fps and NTSC 30fps as Black + Burst,
composite sync and color bar. Especially for the PAL 24fps standard a pull
down factor of 0.1% can be set additionally to output PAL 23.98fps.
The MC-3.2’s HD tri-level video sync reference generator offers 720p, 1080i
and 1080p formats with frame rates at 24Hz, 25Hz, 30Hz, 50Hz, 60Hz and
the respective pull down factors of 0.1%.
The audio clock generator of SMART CLOCK HD 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 of x1,
x2 and x4 for a maximum clock rate of 768.0kHz. For the synchronization of
older digidesign ProTools™ systems, the respective 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. Additionally all common pull up and down factors
can be adjusted freely for film/video and audio transfers.
All reference signal generators can be set independently. Phase relations
between the individual generators are recognized and adjusted
automatically by the system.
The design advantage of the MC-3.2 SMART CLOCK HD is its high-precision
clock frequency basis, from which all reference signals are simultaneously
derived. As a result, the individual clock signals generated feature the same
frequency accuracy and time base! The frequency generation is accurate
to < ± 0.5ppm and thus complies with AES 11, Grade 1, as well as broadcast
specifications.
This all makes MC-3.2 SMART CLOCK HD without doubt the most flexible
A/V clock generator in a ½ 19“ case currently available in the industry!
