OPERATION
Once the BH184 unit has been correctly set up it should not normally require further
adjustment during the lifetime of the installation unless there is some change to the cable run
or associated equipment.
PART 2: USING THE BH184 UNIT AS A DISTRIBUTION AMPLIFIER
INSTALLATION
The BH184 unit may be installed at any convenient point in the video feed. The 12V DC
power supply is connected to the spring-loaded connector labelled ‘12V DC’. If you are not
using the BH98 power supply included with the unit then any 12V DC supply used must be
regulated. An LED next to the signal input connector shows when power is connected.
The video input is connected to the BNC coax connector labelled ‘VIDEO IN 75R’. The two
video outputs are connected to the BNC coax connectors labelled ‘VIDEO OUT 75R’. The
outputs from the two BNC connectors will be identical.

ADJUSTMENT
The BH184 unit is adjusted in the factory for Unity. An input signal of 1.0V peak to peak @
75R will give an output signal of 1.0V peak to peak @75R.
If the monitors or other items of signal receiving equipment are some distance from the
BH184 unit it will probably help to increase the signal output of the BH184 unit. Please refer
to
PART 1 /
ADJUSTMENT
for details.
OPERATION
Once the BH184 unit has been adjusted it is not normally necessary to make any further
adjustments for the life of the installation provided there are no significant changes to the
cable run or associated equipment.
