The AxunWorks SCA101 switch is the only known switch on the market that supports simultaneous use of both JP21 and SCART cables, acting as both a switch and a converter! It also supports 10 inputs and multiple output options. Single output is recommended, but simultaneous outputs are possible. There's also some expert options such as RGB gain control and H&V controls. Please note that the sync stripper outputs TTL level sync, so please leave that off if output is going into SCART equipment.
