Product description
Multiband amplifier is intended for amplifying TV signals in VHF and UHF bands.
There is a possibility to adjust the gain of the amplifiers in every sub-band. The gain increases by turning regulators 7-10
clockwise.
The amplifier can provide power (+5 V) to external equipment through one UHF input connector (4). It is turned on and off
by switch (14). Power feed for external equipment has short circuit and overload protection. In normal conditions indicator
(11) glows green. If short circuit or overload conditions are detected - glows red.
Amplifier has 30 dB LTE suppression filter
According to the standart ETSI EN 303 354 V.1.1.1, this TERR TV band amplifier type is Launch, selectivity clasification 0.
The amplifier is intended for indoor use only.
Safety instructions
Installation of the amplifier must be done according IEC60728-11 and national safety standards.
The amplifier is powered from mains 230 V~. This voltage is dangerous to life.
Any repairs must be done by a skilled personnel.
Amplifier is double isolated from the mains 230 V~.
Do not remove the cover of the power supply section, without disconnecting the unit from the mains supply.
Do not plug the amplifier into the mains supply if the power cord or plug is damaged.
Do not plug the amplifier into the mains supply until all cables have been connected correctly.
The mains socket must be easily accessible.
Amplifier shall not be exposed to dripping or splashing water.
Avoid placing amplifier next to central heating components and in areas of high humidity.
If the amplifier has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before plugging
into the mains.
Do not insert any objects into ventilation openings.
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths,
curtains.
Mount the amplifier in vertical position with power supply located on the left. The amplifier must be fixed with steel screws
Ø 3.5-4 mm. The screws are not included in a package. Mount in locations where children not likely to be present. Shields
of cables must be connected to main potential equalization bus.
From top, front and bottom of installed amplifier must be at least 10 cm free space.
