House amplifiers HA234R65, HA235R65, HA236R65, HA236R85, HD234R65, HD235R65, HD236R65, HD236R85
Product description
The house amplifiers (in text - amplifiers) are intended for amplifying and distributing TV signals in cable TV networks.
HA234R65, HA235R65, HA236R65, HA236R85 amplifiers are powered from the mains 230 V~.
HD234R65, HD235R65, HD236R65, HD236R85 amplifiers are remote powered from line 24...65 V~ through RF IN port.
All amplifiers are intended for indoor use only.
Safety instructions
Installation of the amplifiers must be done according IEC60728-11 and national safety standards.
Any repairs must be done by a skilled personnel.
HA234R65, HA235R65, HA236R65, HA236R85 amplifiers are powered from the mains 230 V~. The amplifiers are double
isolated from the mains 230 V~.
HD234R65, HD235R65, HD236R65, HD236R85 amplifiers are remote powered from line 24...65 V~ through RF IN port.
In both cases voltage is dangerous to life.
To ensure safe operation of the amplifiers follow these instructions:
do not remove the cover of the power supply section, without disconnecting the unit from the powering;
earthing of the amplifiers must be done firstly before powering it;
do not plug the amplifiers into the mains supply if the power cord or plug are damaged;
do not plug the amplifiers into the mains supply until all cables have been connected correctly;
the mains socket must be easily accessible;
avoid placing the amplifiers next to central heating components and in areas of high humidity;
if the amplifiers have been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before powering;
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.
External view and operating controls
The arrowhead indicates the value of the attenuator.
All attenuators are set to zero position by default.

Test points
Input test point is bi-directional. It is used for return path signal measurement during return path
adjustment as well as for forward path input signal monitoring during network troubleshooting.
Output test point is directional. It is used for forward path output signal measurement during
forward path adjustment as well as for return path input signal injection during return path adjustment.
In all cases test point gives 20 dB attenuation.
