a scart distribution amplifier and selector switch with 9 volt UK plug in power supply. This unit has 4 sets of connectors input channel 1 has 3 phonos and S video (SVHS) (input only) , channel 2 and 3 have SVHS in only and Scart in and out and channel 4 has SVHS out only  and scart in and out. The input can be set as Channel 1 or 2 or 3 or 4 or it can auto detect which input has a signal.

The amplification function will not make a low signal into a high signal but it does isolate the outputs so  the extra TVs will not overload the signal causing distortion.

this unit does not do RGB
