1 Important information on safety and assembly
• Mount the amplifi er …
- on a non-fl ammable 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 amplifi er 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 amplifi ers built into a die-cast housing are
for supplying small building units and CATV house-networks. Beside the adjustable amplifi er
they contain the diplex fi lter and the return channel amplifi er. 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 amplifi er housing.
3 Assembly
Mount the distribution amplifi er in such a way …
–
that the convection cooler is not obstructed by the vertical cooling fi ns on the
back of the housing.
– that the permissible ambient temperature is maintained (measured in the air-
stream below the housing).
.
•
Screw the distribution amplifi er onto the wall according to the dimensions in Fig. 1
(screws: Ø ≤ 4.8 mm).
• Fasten the earthing line (Cu ≥ 4 mm
2
) to the earthing connection A securely.
• 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 confi guration
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 G in 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 Confi guring the return channel
•
Position the jumpers
F (Fig. 2)
according to Fig. 3 (factory setting – active).

Closing the housing cover
• Put the housing cover onto the housing and press it on so that the metal fi ns
press against the housing from the inside in closed state.
• Use screw
B
to fasten the housing cover (Fig. 1).
5 Specifi cations
The distribution amplifi ers fulfi l 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 specifi cations are typical values which in practice may be
higher or lower inside the tolerance range usual for the branch.
