Level adjustment
The optimal output level (measured at the output of the
base device) is as follows:
•
100 dBµV for PAL channels
•
90 dBµV for QAM channels
•
96 dBµV for radio (FM) channels
To enable the setting, the level regulators of the indivi-
dual plug-in cards are set accordingly (Fig. 14).
The level adjustment can be done via HE programming
software depending on the plugin-card.
Note:
Under no circumstances should a skewed position be
set to compensate outgoing cable attenuation by means
of different level adjustments of the plug-in cards! For
this purpose use output coupling field
U-901
(order no.
380 190) or
VZN 8
(order no. 380 191).
