Splitband amplifier MSA103
Product description
Amplifier is designed in splitband technology for amplifying SAT IF and terrestrial TV signals. Amplifier can work in two modes:
• splitband - one input for both bands
• insertion - separate inputs for SAT IF and Terr. TV bands
It is possible to feed external network equipment through RF signal input and output connectors.
The amplifier has fixed slope pre-corrections for both SAT IF and Terr. TV bands. There are independent switchable gain
and slope regulators for both bands too.
According to the standard ETSI EN 303 354 V.1.1.1, this Terr. TV band amplifier type is Launch, selectivity clasification 0.
The amplifier is designed for indoor use only.
Safety instructions
The amplifier is powered from mains 230 V~. This voltage is dangerous to life.
Installation of the amplifiers must be done according IEC60728-11 and national safety standards.
Any repairs must be done by a qualified personnel.
The 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.
To disconnect the amplifier completely, disconnect plug from the mains socket.
The mains socket must be easily accessible.
The amplifier shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, shall
be placed on it.
Avoid placing amplifier next to central heating components and in areas of high humidity.
No naked flame sources, such as lighted candles, should be placed on amplifier.
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 four RF connectors on the left. The amplifier must be fixed with steel screws
Ø 4-4.5 mm. The screws are not included in a package.
From top, front and bottom of installed amplifier must be at least 10 cm free space.
