axing BVS 20-00 Betriebsanleitung Seite 4

Field of application:
The devices are suited only for amplifying radio and television signals in the
house! If the device is used for other purposes, no warranty is given!
The illustrations show application examples for the distribution in star (1) and
tree structure (2).

Erdung | Grounding
Grounding and Mounting:
To avoid dangerous power surges (e.g. risk of fire
and electrocution), all devices have to be grounded
according to EN 60728-11. Use the screw terminal
at the device (3).
Use the mounting screws included in the delivery
and the mounting holes of the devices (4).
RF Installation:
4
Connect the input of the amplifier
to the interconnection point.
Connect the output of the amplifier
to the antenna sockets or the taps
used.
4
Use a highly shielded coaxial cable
with an F connector. Suitable cables
and connectors can be found in the
current AXING catalogue or under
www.axing.com.
4
The test ports at the input is bi-
directional. This test point has to be
activated or deactivated with the
adjacent jumper.

Adjustments of gain and slope:
Gain and slope are adjusted with the PCB sitches (5 and 6) in the forward
frequency range.
The jumpers (7 and 8) are used to adjust the interstage attenuation and
slope in the forward frequency range.
Return path modules
For the amplifiers there are return path modules (BZU 20-xx) available.
4
Before inserting the return channel module, the 4 DIP switches (see 9
in above drawing) must be set to the OFF.
4
When the RC module is removed again, the 4 DIP switches must be set
to the ON position again. This is the only way to guarantee troublefree
operation.
Note: If return path modules with 5...65 MHz are used, VHF/band I in
forward path is not possible.
Power indicator LED:
The amplifier comes with LED (POWER) which shows the operation mode:
a
green = in operation
a
out = no power supply
