Input configuration socket
The nominal RF input level for the VX 2x B is 70 dBμV per channel. If, due to special
signal scenarios, the input signal is strongly sloped or much higher than the nominal
level, pluggable input configuration modules can be used in order to facilitate the
signal alignment.
