Hi I've just been delivered my new Traktor Kontrol S2
however Its not working - I have a MAC Air 2020 (RCA cable) and it won't link up and just flashes on and off. do I have to buy another cable? -I've plugged the cable that came with it into a plug socket (mains) and nothing..or do I need another adapter- the instructions are very vague- I am a complete beginner.
none of the virals online say anything about the simple basic plugging in and switching it on!
