Terra MSA100 Quick Start Manual

Splitband amplifier MSA100

Product description

The amplifier is designed for amplifying SAT IF and terrestrial TV signals.
There are three connectors with DC feeding for external.
22 kHz signal can be passed to SAT IF input from TERR TV + SAT IF output or from 22 kHz control connector, depending
on the possition of 22 kHz path selection switch.
The amplifier has independent switchable gain and slope regulators for SAT IF band and TERR TV band and fixed slope
pre-corrections for both SAT IF and TERR TV bands.
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, DC OUT2 and 22kHz connectors underneath.
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.

Installation

The amplifiers should be mounted vertically with four RF connectors on the left, DC OUT2 and 22 kHz connectors
underneath, in order to ensure good ventilation conditions. Ground the amplifiers housing. Connect the amplifier into the
mains supply lastly.
WARNING!
Overload or short cuircuit on DC OUT1 connector triggers protection of power supply. The amplifier self recovers
when short circuit or overload is eliminated.
