Description
Access to SAT IF lines is controlled by 14/18V and 0/22 kHz signals, which come from the customers receiver through the RF cable. There are 3 gain controls for equalising the signal level from different lines:
1. for terrestrial TV signal
2. for High band SAT TV lines {H, Hi; V,Hi}
3. for Low band SAT TV lines {H, Lo; V,Lo}
SAT TV circuits of the multiswitch are powered from the receivers and do not need any external power supply. The Terrestrial TV path must be powered through the horizontal polarisation SAT TV lines and these lines are powered either by the launch amplifier {V5 100T} or by an external PSU inserted anywhere in the system.
Maximum Output is satellite 93dBµV, terrestrial 90dBµV. SATgain at outputs 1-8, 6.5-14dB; 9-16, 5-11dB; 17-24, 3.5-8dB; 25-32, 2-5dB Terrestrial gain at outputs 1-8, 5-10dB; 9-16, 4-8dB; 17-24, 3-6dB; 25-32 2-4dB
