Connecting headphone amp to 500 series set up

[aij]

I have an Arche amp with Focal headphones. Naim have provided a bespoke 5 pin Din cable to connect 500 setup to the Arche but I’m unsure where to connect , I’ve tried input 4 on the 552 pre-amp and selected each of the record out buttons but no sound. Ross at Naim is trying to resolve but not been able to catch each other during the week, I wondered if anyone has any ideas for me to try over the weekend, please? I assume I have to select one of the record buttons as by selecting an input button I’m de-selecting the music source at the same time!

Be sure that the interconnect is correctly wired so the REC OUT pins on the DIN are connected.
