Hi thanks againI checked the manual. The inputs are female and the outputs are male, just like Wayne P said. So you need male input connectors and female output connectors, which is standard, again like Wayne P said.
Also agree with his recommendation that a Cable complete with male RCA on the other end would be the better choice, more reliable, would not stick out the back of the box as far. But the kind of adapters you are talking about would work also. not sure what is available down under where you are.
Thanks Wayne exactly what I thoughtAssuming your AVR has female RCA outputs, you’ll want male RCAs on the cable ends. A picture is worth a thousand words, as they say. You’ll need a pair of each. Shouldn’t be hard to find in the pro audio section of your local guitar shop. Try to get either Switchcraft or Neutrik XLR plugs, not what's shown in these pictures.
