VIDEO LINE AMPLIFIER WITH EQUALIZER
The LVH-4 is the ideal choice in installations where video signals are being fed into long
cables, or where a low video signal needs to be amplified. Gain and equalization may be
adjusted on the LVH-4 to drive video cables as long as 600 meters. The unique power supply
input allows the unit to be powered from a wide variety of existing AC or DC power sources.

a soft lint-free and moistened cloth. Never use alcohol or solvents!
• There are no serviceable parts inside the device. Maintenance and service operations are
only to be carried out by authorized dealers.
• Damage, caused by manual modifications on the device are not subject to warranty. If the
device is used for other purposes than originally intended or if it is not correctly connected,
the product may suffer damages and the guarantee becomes void.
• This product is allowed to be operated with 12-24 V AC or DC. This device falls under

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 (max.
length 300 m) to the jack INPUT.
2 Connect the subsequent unit (e.g. monitor) via a 75 coaxial cable with BNC plugs (max.
length 300 m) to the jack OUTPUT.
3 To power the unit 12-24 V AC or DC from the signal source (fig. A) or from an independent
power source are required (fig. B). Connect an independent power source (e.g. power
supply unit, battery) to the terminals DC 12-24. Always observe the correct polarity.
Connect the marked core to the left contact "+".
4 The gain can be adjusted with the Potentiometer GAIN and the equalization with the
potentiometer EQ. Figure C gives you a chart with recommended beginning settings of
gain and equalization for various lengths of cable. The settings may then be further fine
tuned for an optimum, high-quality video transmission.
