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.

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?

Hi Alastair,
Good day.
The plug of A2 is 3.5mm jack plug,and you can try to connect the A2 sub output to an active subwoofer with 2 RCA-6 inputs (L & R).
Thanks & Best regards,
Bill
