1 COME IN!
We are happy to welcome you in the circle of the Studer D19 Master-
Sync's users, and we felicitate you on your selection. Thanks to Studer's
experience collected during more than 40 years of business in the pro-
fessional audio products field, you may expect that the performance of
your new unit will fulfill your highest demands.
1.1 Basic Information
The Studer D19 MasterSync is housed in a 19", 1U enclosure.
Its generator section can be synchronized to a video, word clock, or
AES/EBU signal with automatical switchover. Should the external
clock be missing, a low-tolerance internal reference clock with auto-
matical and manual switchover is available.
The distributor section distributes one word clock signal to six outputs,
and up to four AES/EBU signals to 16 outputs. For the latter, combin-
ations of 1 to 16, 2 to 8, and 4 to 4 can be selected with a DIP switch
located at the rear panel.
Generator: The internal generator has an internal low-tolerance reference clock
(1 ppm); selectable frequencies are: 32 kHz, 44.056 kHz, 44.1 kHz,
47.952 kHz, and 48 kHz.
For external synchronization, a video signal (25 or 29.97 fps), an AES/
EBU signal or a word clock signal can be used, synchronization to an
optical MADI signal is available as an option. Signal selection is per-
formed automatically, with priority in the same order. Termination for
the video input is selected with an internal jumper between hi-Z and
75
W
. The word clock input is the same as the one of the word clock
distributor.
For word clock and AES/EBU sync signals the input frequency is dis-
played, however without drop/non-drop recognition. In case of video
sync the sampling rate is generated according to the front panel selec-
tor's position. It is, for instance, possible to convert a 29.97 fps video
signal to a 44.056 or 44.1 kHz sampling rate signal, as set with the
DROP switch.
AES/EBU Distributor: The four inputs and four outputs each are connected to 15-pin D-type
connectors. The distributor can also be used for distributing an AES/
EBU frame clock.
Word Clock Distributor: The input and the outputs are equipped with BNC sockets. The input
can be terminated with 75
W
using an internal jumper. Input sensitivity
is 1 V
pp
, independent of any DC level. The word clock outputs cannot
be connected to the word clock input only, but also with the internal
generator's clock (setting with an internal DIP switch). The output 4...6
polarity can be inverted with an internal jumper (connect P38 and P39).
