HDA4 & HDSR

Model HDA4 & HDSR
HD/SD SDI Distribution Amplifiers

The HDA4 and HDSR are studio quality HD/SD SDI 1x4 and 1x2 (respectively) distribution amplifiers with equalized input and selectable reclocked/non-reclocked outputs.

Each output can drive up to 330 feet (100 meters) of HD/SD SDI with embedded audio (Belden 1694). A front panel switch selects between reclocked and non-reclocked outputs. The outputs are unity to 100 meters/330 feet.

The enclosure of the HDA4 is small enough that up to four (4) units can fit on a single 1RU rail (RM-4).

The enclosure of the HDSR is designed to be placed in-line with long cable runs, but it can also be rack mounted with up to six (6) units on a single 1RU rail (RM-6-2).

An external 5Vdc power supply is included (120Vac – 5Vdc @ 1A)
