Introduction
CXE160 is a compact distribution amplifier with one active output. It can be
used in house amplifier use as well as in line use with remote powering. There
is no need for separate plug-in modules, because diplex filters, return amplifier
and adjustments are built-in.

Housing
The amplifier can be installed either into a street cabinet or to outdoor
environment. The amplifier should be installed in a vertical position so that the
external cable connectors are underneath. At least 100 mm of free space
should be left above the amplifier to ensure sufficient cooling air circulation. The
class of enclosure is IP54. Note, used connector type might have lower IPclassification than the amplifier housing.
The cover of the housing is closed by a single bolt. There are no hinges. Open
cover is to be removed completely. When closing the cover use a PZD 2
screwdriver to tighten the bolt to a torque of 2.5...3.5 Nm. To ground the
amplifier housing connect at least 4 mm
2
grounding wire (Cu) from a proper
earth to the grounding point.
NOTE! Make sure the input attenuator adjustment (Figure 4 pos. 3) is at its
minimum level before connecting power to the amplifier.

1) Input, 2) Ground, 3) Output
Underneath the CXE160 amplifier there are two cable connection points: input
and output. All coaxial connection points have a standard PG11 thread and they
accept a KDC type adapter or connector.
