Hi Orfeof - you should not experience any deterioration in sound quality - the amps in the Pentas are still used. Whether or not the stereo is on or not when you use the to depends on how you set it up. If you want the Pentas connected to the Beomaster then yes, the stero will turn on when you activate the to and sound will come out of the Pentas. As suggested take a look at the masterlink manual as there are diagrams of various set up options and details of the option settings you need.

im confident the system will work the way you want if you get a 1611 converter - I have pretty much the same set up. Good luck!

Sorry, stupid iPad changed TV to 'to' in the above post but you get the idea!

"I would leave the pentas connected to the stereo (I have a Beolink 7000), if I understand well,  I must use a converter ML / MCL"

No, you need the 1611 converter - which converts Datalink to Master Link and vice-versa. The ML / MCL Converter is a different unit that contains an amplifier and is used for connecting a newer audio source Masterlink to an older MCL - multi-room setup.

Hi everyone and thank you for the answers.

Just a last question (have you patience) using the converter 1611 with the correct set up, when I turn on the TV are the BeoMaster and pentas automatically turned on,  is the sound directly controlled by the TV's remote control ?

Best Regards
