MS11-20-1.qxd 20.09.00 12:57 Seite 3 2 Safety Hints For your own protection, you should read the safety hints carefully before installing the GigaSwitch multiswitch. The manufacturer accepts no responsibility for damage caused by non-observance of the safety hints, or by inappropriate handling. > > > The components must be mounted in dry rooms on flat, non-flammable surfaces. Air circulation slots on the components must permit unimpeded circulation.

MS11-20-1.qxd 20.09.00 12:57 Seite 4 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.

All other outputs are fixed in terms of their switching position. The setting of this switch is irrelevant for and not applicable to DiSEqCcompatible receivers. 4.2 Setting of terrestrial Inputs Terrestrial signals can be fed into the system in separate bands, or as a broad band signal.

MS11-20-1.qxd 20.09.00 12:57 Seite 6 5.3 LNBs > > > 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 output level should be >75 dBµV. The LNBs receive their mains power supply via the basic unit GigaSwitch 11/20G. Please note the maximum power supply as per the technical specifications. 5.

Please ensure that the levels of the various satellite signals fed into the system are approximately equal in strength. The outputs for participants 5…10 and 16…20 supply a higher output level in the satellite band. You should use these outputs to connect participants with longer cable connections.
