VIDEO DISTRIBUTIONAMPLIFIER 1:4
The video distribution amplifier LVH-2 amplifies and distributes one video signal to four
outputs. Video inputs and outputs are made on the front panel via BNC jacks. Power
connections are made using block terminals on the rear panel. The input stage features a
parallel output for feed-through of the input signal. The gain potentiometer allows adjustment
from -1 dB to +7 dB.

OPERATION
Prior to connecting switch off all units and do not turn them on again until you have made all
necessary connections.
1 Connect the signal source (e.g. camera) via a 75 coaxial cable with BNC plugs to the
jack INPUT. The input signal fed through is available at the output LOOP OUT. This output
allows to connect the line input of another LVH-2 or a different unit (e.g. monitor). If the
output LOOP OUT is not used, the supplied 75 terminator plug must be connected (Fig.
A).
2 Connect each unit to which the video signal is to be distributed (e.g. monitor, recorder) via
a 75 coaxial cable with BNC plugs to the jacks AMPLIFIED OUTPUTS. Unused outputs
need not to be terminated (Fig.A).
3 To power the unit 12-24 V DC are required. For this purpose, connect a power source (e.g.
power supply unit, battery) to the terminals DC .Always observe the correct polarity.
Connect the marked core to the left contact (Fig. B).
4 The gain can be adjusted with the recessed potentiometer GAIN from -1 dB to +7 dB.
Adjust the potentiometer for 1 Vpp video level on your instrumentation. In the absence of
test equipment, adjust the value via the LED level indicator of the LVH-2. First turn the gain
counterclockwise. Then advance the gain clockwise unit the LED level indicator lights up.
