GB 15LNB Offset voltageIf the cable down from the antenna is very long, the voltage atthe LNB could be too low to change the polarization. You can in-crease the voltage to the LNB by 0,5 V.SatelliteSelect the satellite towards which you want to aim the antenna.Predefined channelSelect one of the preprogrammed channels. Adjust the antenna andstart the channel search the same way as described on page 13.Multisatellite/DiSEqC Switch ConfigurationSelect this alternative when you have a single antenna equippedwith 2 LNBs, or two antennas with one LNB on each, and wantto watch channels from Sirius and Thor.In this case you first must connect the LNBs to an external switchsince there is only one antenna input on the Mediamaster. Onceinstalled the switch automatically selects the correct LNB for theselected channel.This external switch is better known as a DiSEqCTM switch. Sincethe switch can be located close to the LNBs, you only need onecable down to the Mediamaster.Connection of a DiSEqC switch• Connect the cable from the LNB intended for channels fromThor to the connector marked LNB 1 (A) on the switch,• and the cable from Sirius to the connector marked LNB 2 (B).• Connect the antenna cable to the connector marked ReceiverOUT on the switch. Connect the other end of this cable to theinput marked ANTENNA on the Mediamaster.FIRST TIME INSTALLATION
