(see technical specifications). 3.2 GigaSwitch 11/20K (Part No. 0000/3228) The GigaSwitch 11/20K is the cascade unit in the multiswitch range. This unit receives its power supply from the basic unit GigaSwitch 11/20G. The GigaSwitch 11/20K unit can thus only be used in conjunction with the basic unit.
3.3 Intermediate Amplifier 9Z (Part No. 000/3231) The intermediate amplifier 9z has been designed to compensate for the damping effect of 25m of multimedia cable, or of 40m of CoaxSat 2150 cable, when used to transmit satellite signals. The amplification of terrestrial signals can be adjusted. 3.4 Distributor 9V This is used to achieve a three-way split of main-line connections, while providing a high degree of insulation.
DiSEqC control functions can utilise the 22KHz control signal to switch to the Low Band set- ting of Eutelsat 13°. All other outputs are fixed in terms of their switching position. 4.2 Setting of terrestrial Inputs Terrestrial signals can be fed into the system in separate bands, or as a broad band signal. Use the switch provided to set the required function: a) Switch in up position Separate inputs for VHF, UHF and FM are activated.

You may choose quattro, dual output or twin LNBs, but not universal twin types. > Use only high-quality LNBs from reputable manufacturers, such as TechniSat Part. No. 0000/8880, providing either linear or diagonal frequency compensation. The out- put level should be >75 dBµV.
Where input signals are weak, a low-noise pre-amplifier with high damping should be employed. > If a 11/20K unit is cascaded directly with a 11/20G basic unit it may be necessary, depending on input levels, to insert a damping controller in the terrestrial signal path between the two units.
