We are happy to welcome you in the circle of the Studer D19 Multi-
Feed'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.
The Studer D19 MultiFeed is housed in a 19", 1U enclosure. It distri-
butes one word clock signal to six outputs, and up to four AES/EBU
signals to 16 outputs. For the latter, combinations of 1 to 16, 2 to 8, and
4 to 4 can be selected with a DIP switch located at the rear panel.
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.
The input and the outputs are equipped with BNC sockets. The input
can be terminated with 75
is 1 V
, independent of any DC level. The word clock outputs cannot
pp
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).
Two units can be connected with a cable (order no. 1.680.025.00). Both
units must be fed with the same sync signal and must have identical
settings. In case of a malfunction, the supply as well as the AES/EBU
and word clock signals are taken from the second unit. In order to avoid
phase jumps during switchover, both units are continuously syn-
chronized.
It is also possible to install a second, redundant power supply into a
single unit (jumper P60-P61 must be moved to position P59-P61). The
"WARN" LED indicates a supply failure; however, normal operation
is still maintained.
The D19 MultiFeed (Order No. 60.680.010.00) is shipped with an
IEC 320/C13 socket, a hex-socket screwdriver (2.5 mm), and this op-
erating manual.
