Hello Maxime, MasterLink signals and PowerLink signals are not the same! But you can use RJ45 connections (with shielded CAT7 cabling) for both ML and PL. Check the BeoLink handbooks here: https://beoworld.org/beotech/reference-manuals-beotech/ A BeoLink active + IR eye will most likely be a good option for you: Connect the BeoSound 9000 and the BeoLink Active with MasterLink cabling, and the BeoLink Active with the BeoLab 6000s with PowerLink cabling. With an IR eye, and an extra Beo4 you can listen to, and control, the BeoSound 9000 from the Chambre. Someting like this (think BS9000 where you see BS5/BM5): Login to view image Hope this helps

Bonsoir Merci beaucoup pour votre réponse et les schémas. 👍🏻 Je vais trouver une autre solution. Penser vous qu'un branchement avec des boitiers CPL fonctionne ? BS9000---POWERLINK RJ 45--- CPL BL6000---POWERLINK RJ45---CPL Merci
