It disposes of two input signal connectors for the mixing of channels
coming from two systems. If only one of the inputs is used, it is advi-
sable to load the unused input with 75 ohm, ref. 4061.
The amplifier disposes of an output connector and a Test socket
(-30dB) located at the top of the front panel.
The amplifier is powered with 15V via an eight-wire flat cable, the
same type as that used for powering the other modules of this system.
This product has been manufactured in a fully shielded zamak
enclosure and the gain can be selected on site.
This amplifier finds its main application as a line extender in small
CATV networks.
