Field of application
The devices are suited only for amplifying radio, television and DOCSIS signals
in the house! If the device is used for other purposes, no warranty is given!
Equipotential bonding and Mounting
To avoid dangerous overvoltages (attention: risk of fire/death), the devices
must be connected to the equipotential bonding according to EN 60728-11.
Use the equipotential bonding connection attached to the device (1).
To connect the outer conductor of the coaxial cable to the equipotential
bonding, use e.g. earth connection blocks CFA or earthing angles QEW at
the input and output of the amplifier.
Use the mounting screws included in the delivery and the mounting holes
of the devices (2).

Remote power feeding
The BVS 20-66 is supplied over the coaxial cable. The jumper (PS) is used to
decide between remote power supply at the input (position „Eingang“) or
at the output (position „Ausgang“).
Install according to this a power inserter TZU 15-01 at the input or at the
output of the amplifier.
Connect a remote feed transformer BZU 100-00 via a remote feed cable
BZU 150-00 to the power inserter.
RF Installation
Connect the input of the amplifier to the interconnection point. Connect the
output of the amplifier to your house distribution.
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.
Downstream adjustments
Use the jumpers (DS J1 and DS J2) to adjust the interstage attenuation and
slope.
If this is not sufficient, adjust the the input attenuation and slope using the
attenuators (DS 1 and DS 2) in the forward frequency range.
Upstream adjustments
Use the jumpers (US J1 and US J2) to adjust the interstage attenuation and
slope.
If this is not sufficient, adjust the input attenuation of the return path with
the attenuator (US).
Activate and deactivate the test port at the input
The test port at the input is bi-directional. This test port must therefore be
activated for measurement by means of a jumper:
Jumper in position ON = test port active
After measuring or adjusting the level of the amplifier, the measuring socket
must be deactivated again:
Jumper in position OFF = test port deactivated
Power indicator LED
The amplifier comes with a LED (POWER) which shows the operation mode:
green = in operation
out = no power supply
