Connection
!
Before inserting new or replacing existing casset-
tes, it is absolutely necessary to disconnect the
mains plug!
First remove the corresponding fixing screws from
1
the holding frame, then insert the cassettes (e.g
from left to right) into the free plug-in locations,
and finally fix them with the screws removed be-
forehand.
4 spare screws are fixed to the holding frame.
When the head station is connected to the mains
2
supply, all cassettes are automatically connected
via the plug-in connectors on the contact rail with
the required operating voltages supplied by the
switched-mode mains unit.
It is possible to connect every SAT cassette to one
3
of the 4 input distributors. Each of the 4 input distri-
butors is suited for remote power supply, that is the
LNC's can be supplied with the operating voltage of
+18 V DC/1 A.
!
Operation with twin LNC's.
To enable the setting of the vertical polarisation of
twin LNC's, it is necessary to remove the corres-
ponding supply plug ( +18 Volt LNC voltage) for the
RF input concerned (A, B, C or D) on the base plate
of the head station before inserting the cassette(s)
(see figure below).
If necessary, pull out the cassette(s) before.

All output signals of the cassettes are added up in
4
the output collector then passed to the hybrid
amplifier.
The hybrid amplifier allows for an output level of
max. 106 dBµV. The operating voltage of 24 V DC
required for this is supplied by the switched-mode
mains unit.
5 The level controls at the front side enable a precise
adjustment of the output signals.
6 An additional monitor output (approximately
-20 dB) enables the connection of a measuring TV
receiver for service or monitoring.
7 It is possible to operate head stations with less than
12 twin or single cassettes, and several head sta-
tions can be linked.
8 In the case of service it will suffice to replace the
defective cassette with one of the same type; it will
be programmed automatically.
! Single cassettes have a higher output level than
other cassettes. Adjust this level to that of the other
cassettes using the corresponding level control
(max. 106 dBµV).
