How do I correctly connect satellite and terrestrial TV signals to a TERRA Multiswitch?

[MacWalter]

To properly connect your satellite and terrestrial TV signals to a TERRA MV908L, MV912L, or MV916L Multiswitch and ensure optimal performance, follow these steps: First, for satellite TV signals, connect the IF signals to the inputs as labeled on the multiswitch. Utilize the gain controls for each satellite line to equalize the average signal level, achieving a balanced signal. Second, for terrestrial TV signals, connect the signal to the designated input. Use the control near the terrestrial TV input to adjust its level optimally. Be sure the terrestrial TV signal level doesn't exceed the specifications' upper limit and avoid setting it too low to prevent interference. Subscribers have constant access to the terrestrial TV line, while access to satellite TV lines is managed through analog or DiSEqC signals from the receiver via the RF cable. Analog control includes 14V/18V for polarization selection, 0 kHz/22 kHz for band selection, and a 22 kHz tone burst for satellite selection. Without DiSEqC, only satellite A is accessible. The multiswitch requires a stabilized +18V power supply. Confirm all cables are correctly connected before applying power to prevent damage. In the absence of a central power supply, an external 18V power supply can be connected to the "AUX 18V" connector. Following these instructions ensures proper setup of your TERRA Multiswitch.
