Just got a Synergy Uberschall module and and using it in the legacy Randall RM50. Wondering if anyone else has used these modules in legacy gear? When using the switch on the modules PCB, to select which channel is used the module is active, SINGLE selects the top/red channel and only the red LED is lit. Setting the PCB switch to DUAL selects the bottom/blue channel, but both LEDs are lit. Is that normal? https://photos.app.goo.gl/aetK2EHxCfqf6y8u6
