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 (60 meters for
the passive bypass versions) 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 has two 1x4/3 distribution amplifiers that can be individually configured to listen on
either input, giving 4 different options, input 1 to all outputs, input 2 to all outputs, inputs 1 to
first group with 2 on second group, or input 2 to first group and 1 to second group.

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.

The DA-3GHD-2x4 supports a number of different formats. The correct configuration can
either be set with a DIP switch or with the GYDA system controller. The layout of DA-3GHD­2x4 is shown in the drawing below with the DIP switch to the upper left position.

Figure 2: DA-3GHD-2x4 module DIP switches

DIP switch configuration must be set according to the table below:

Table 2: DA-3GHD DIP switches

All DIP switches are off when pointing towards the release handle.
