Congratulations on your purchase of the Burst
Electronics model HDA4 or HDSR digital video
distribution amplifier. We hope that this manual will
cover any questions you may
have concerning the
operation of this product.
The HDA4 accepts an SD/
SDI or HD/SDI signal and
distributes the signal to four
outputs. The HDSR is a two
output version designed to
be placed inline with long
cable runs. The unit is
operated from an included
5Vdc power supply.
Introduction
Product Description
The HDA4 and HDSR are HD/SD SDI reclocking
distribution amplifiers capable of driving SDI video
down 300 feet of quality video cable (RG6/U). The
input is equalized. The outputs can be selected to
bypass or reclock the incoming video signal.
Hardware
This section of the manual will explain the functions of
the front panel switches and indicators.
Reclock On/Off - When ON, the unit will reclock
the outputs. When OFF, reclocking is bypassed.

Lock – The LED is Green indicating the input video
signal is present. The LED is off when indicating that
incoming digital video is not present.
Power—ON/OFF power switch. Up position turns
power ON, Down position turns power off.
5Vdc – Power connector (see Specifications for
power requirement).
SDI Input – This is the input BNC for SDI video.
SDI Outputs – Four BNCs video output
connections (HDA4) or two BNC video output
connections (HDSR).
