KEF KUBE into tape loop circuit

Hello, looks like I need some advice integrating a KEF KUBE 107/2 into my 282 tape loop circuit.
It’s my understanding that a ‘single’ din connector (in picture) with input/out leads should be used and into the hdd in/out port, for example. This creates the correct, and “safe” loop between the two units? BTW, I plan on upgrading the plug with a custom made connector and wiring. But I could request them to make up two separate interconnects as well I suppose.

Thanks
