Hi puck5862,
You need mark.2 (Fully Wired) Powerlink cable for your MCL2P. You can find this via my sponsor link at the foot of the page if required.
If you are connecting a subwoofer to an AV7000, you can:-
1) Connect Beolab 2 directly to the AV7000
2) Connect a passive sub (eg. Beovox Cona) to the output of the MCL2P along with the RL6000's
3) Use a Powerlink to Amplifier Cable (see my link below for details) to connect a non-B&O active sub directly to a Powerlink output on the AV7000.
Hope this helps, please feel free to ask if you have any questions.
Best regards,
Steve.
