Please can you tell me what plug is needed on a subwoofer cable to fit the subwoofer socket on the A2? It doesn't look like a socket for an RCA-6 plug or a 3.5mm jack plug. Could it be a PPX RCA socket? I need to connect the A2 sub output to an active subwoofer with 2 RCA-6 inputs (L & R). Thanks in anticipation of your help with my enquiry?  Alastair

thanks for the reply. I tried but it does not work with headphones.  Only it works as a connecting input incoming and not outgoing.  By connecting external sources such as smartphones works.
