1 Important information on safety and assembly
• Mount the amplifier …
- on a non-flammable surface (wall),
- in a dust-free, dry environment,
- protected from moisture and water (rain or splashing water),
- at a place protected from direct sunlight,
- away from the immediate vicinity of heat sources,
- taking the maximum permissible operating temperature into account.
• Do not perform installation and service work during thunderstorms.
• Only install the unit when disconnected from the 230 V mains power supply.
• Check the coaxial cables for short circuits before starting. Eliminate any.
• No liability is accepted for any damage caused by a faulty connections and /
or inexpert handling.
• Observe all applicable standards, guidelines and directives (VDE0100,
VDE0185, VDE0855, VDE0860, DIN18015, EN61319-1, EN50083).
•
Earth the system via the equipotential bonding connector belonging to the building.
• Only open the cover on the mains adapter if the amplifier is disconnected from
the mains.
• Dispose of the product after use as electronic waste in compliance with the ap-
plicable disposal regulations.
2 Technical description
The interactive multimedia capability distribution amplifiers built into a die-cast housing are
for supplying small building units and CATV house-networks. Beside the adjustable amplifier
they contain the diplex filter and the return channel amplifier. The levels of the input signal
and of the return channel signal can be adjusted from 0 … -20 dB and the level of the line
equalization from 0 … 18 dB. The power supply is integrated in the amplifier housing.
3 Assembly
Mount the distribution amplifier in such a way …
–
that the convection cooler is not obstructed by the vertical cooling fins on the
back of the housing.
– that the permissible ambient temperature is maintained (measured in the air-
stream below the housing).
.
•
Screw the distribution amplifier onto the wall according to the dimensions in Fig. 1
(screws: Ø ≤4.8 mm).
• Fasten the earthing line (Cu ≥4 mm2) to the earthing connection Asecurely.
• Connect HF input and HF output.

4 Adjustments
4.1 Removing the housing cover
• Remove screw B (Fig. 1) and take off the housing cover.
4.2 Position of the adjustment elements (Fig. 2)
C– Attenuation control (output level) F– Return channel configuration
D– Line equalization control G– Attenuation 0/10 dB
E– Attenuation control (input/return channel) (output/return channel)
4.3 Level adjustments
• Use the attenuation control C(output level) and E(level of the return channel) to
set the necessary HF level, Fig. 2,
(factory setting – full to right = 0 dB).
• Put the attenuation jumper Gin vertical (“off = 0 dB”) or horizontal direction
(
“on = 10 dB” ).
• Use control
D, Fig. 2, to set the line equalization
(factory setting – full to right = 0 dB).
4.4 Configuring the return channel
• Position the jumpers F(Fig. 2) according to Fig. 3 (factory setting – active).

4.5 Closing the housing cover
• Put the housing cover onto the housing and press it on so that the metal fins
press against the housing from the inside in closed state.
• Use screw B to fasten the housing cover (Fig. 1).
5 Specifications
The distribution amplifiers fulfil the directives EN 50083-1, EN 50083-2/class A,
EN 50083-3/quality class 2, EN 60065 and the guidelines and standards for CE label-
ling.
Unless otherwise stated, these specifications are typical values which in practice may be
higher or lower inside the tolerance range usual for the branch.
