3.2 Power supply to preamplifiers
Transmodulator TO can supply power to preamplifiers through its input. For
this purpose, just connect the preamplifier output to the transmodulator
input. If you
detected by the transmodulator TO that will automatically disable the power
supply.
3.3

Output channels

The vestigial sideband modulator BLV included in the trasmodulators
enables the use of adjacent channels.
RF output channels that are adjacent to each other or adjacent to the earth
TV channels from legal re-emitters (both lower and higher channels) can be
programmed.
If the installation includes external units that use double sideband
modulators, the channels immediately below the ones used by those units
must be free.
3.4 Channels from other units
PA amplifiers include a non-amplified EXT input extension for channels from
other units. The channels added so join the output channels of the TO unit.
3.5 Unit supply
Plug the equipment to the mains, after all the needed connections have been
done: RF and modules power.
To supply the unit, it is necessary to connect every module to the MS-011
(cod. 9120029) support framework, which performs the mass connection.
During 10 seconds, the transmodulator gets initialized and the following
message appears in the OSD menu: INITIALIZING 905-TO
