Multiband amplifiers MA012, MA014, MA016
Product description
Multiband amplifiers are intended for amplifying FM radio signals, TV signals in VHF (1-5, 6-12 channels) and
UHF (21-69 channels) bands.
There is a possibility to adjust the gain of the amplifier in every sub-band. The gain increases by turning regulators 8-13
clockwise.
The amplifier is provided for powering of external equipment from internal power supply (+12 V for MA0XX or +24 V for
MA0XX-24) through input connectors as well as a DC 2.1//5.5 connector 14. The power supply of external equipment has a
short circuit protection. If external equipment summed current is ≤ 0.1 A, an indicator glows green. When current increases,
the protection starts to operate and the voltage supply has beeing disconnected from external equipment. In this case the
indicator glows red.
Voltage supply of external equipment switches on separately for every input with a switch 18.
The amplifier is intended for indoor use only.
RoHS compliant.
Safety instructions
Installation of the amplifier must be done according safety standards and by qualified personnel.
The amplifier is powered from mains 230 V~. This voltage is dangerous to life.
Any repairs must be done by a qualified personnel.
Amplifier is double isolated from the mains 230 V~.
Do not remove the cover of the power supply section, without isolating the unit from the mains supply.
Do not plug the amplifier into the mains supply if the power cord or plug are damaged.
Do not plug the amplifier into the mains supply until all cables have been connected correctly.
To disconnect the amplifier from mains, disconnect plug from mains socket.
The mains socket must be easily accessible.
When amplifier is disconnected from mains, powering indicator does not glow.
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.
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 input connectors underneath.
From top, front and bottom of installed amplifier must be at least 10 cm free space.
This product complies with the relevant clauses of the European Directive 2002/96/EC. The unit must be recycled or
discarded according to applicable local and national regulations.
