1 Product overview
The Flashlink DA-3GHD-2x4 is a multi bit-rate distribution amplifier module providing high
performance media distribution for various signal formats from 19.4Mbps up to 2970Mbps.
The unit can be configured to do cable equalizing and reclocking of SMPTE 424M, SMPTE
292M and SMPTE 259M signal formats.
The two inputs typically provide automatic cable equalizing for up to 70 meters of cable
(Belden 1694A at 2970Mbps) with a total of 6 or 8 reclocked outputs. The DA-3GHD-2x4 will
detect HD and SD rates and automatically switch to the correct output slew-rate.
The reclockers support the bit-rates 270Mbps, 1483.5Mbps, 1485Mbps 2967Mbps and
2970Mbps. For other rates, the reclockers automatically switch to bypass mode, and the DA3GHD-2x4 will work as a non-reclocking distribution amplifier with cable equalizers.
The DA-3GHD-2x4 also supports reclocking of DVB-ASI at 270Mbps, enabling all possible
rates including empty transport streams with only K28.5 padding packets. 4 of the outputs
are non-inverting and suitable for DVB-ASI.
The unit can be configured as a 1 x 8/6 distribution amplifier. Both input ports can be used.
The included intelligent change-over feature gives the ability to change input based on input
signal loss, loss of lock, EDH errors or a combination of the above.
There is also included a passive bypass function (with backplane board C2 and C4) from
both inputs to non-inverted outputs with less than 15 m loss of cable length (enables full
redundancy in case of mains failure).
The DA-3GHD-2x4 is designed for all distribution purposes in studio, duplication and
broadcast applications.
The DA-3GHD-2x4 main board can be combined with 4 different backplane boards giving
functions as follows:

Please observe that –G versions cannot be used with N-Box, Flashlink one module desktop
box, due to mechanical issues.
