Introduction
CXE180 is a compact dual output amplifier. It has two gain modes in one
product. Gain can be selected on the field according to wanted operation.
Higher gain (40 dB) is designed for distribution purposes and lower gain (32
dB) is suitable for line extender use. CXE180 house distribution amplifier
supports 1 GHz frequency range in the downstream and up to 85 MHz in the
upstream.
Adjustments use electrical controls thus eliminating the need of the usual plugin attenuators in the system set-up. Other standard features include reliable
power supply, built-in US amplifier as well as an efficient surge and ESD
protection.
Caution!
− Services and repairs should only be carried out by
authorised personnel.
− Do not touch live parts.
− The amplifier has no separate power switch thus
the power plug must be easily accessible.
− The power must be cut when installing or removing the
amplifier.
− The amplifier must not be operated without its Standard fitted
power supply unit protection cover. The lid must be closed.
