8 Way SCR Multiiswitch with LEGACY Support. The device has 4 satellite inputs and a passive terrestrial input. The switch can distribute signals for 8 (legacy mode) up to 24 (SCR mode) receivers. By cascading several units more receivers can be connected. Thanks to the legacy support the multiswitch can be used even if no SCR set-top boxes are installed yet. The multiswich starts up in legacy mode and switches automatically to SCR mode once an SCR command is received on its output. This is indicated by a flashing LED on that output. The wide range of satellite input levels (49 to 110 dBµV) ensures the multiswitch will work even under extreme conditions.
