Hi- Hoping to resolve an issue The setup TV (an LG) is connected to Beosound Theatre via HDMI-ARC. In turn, Beosound Theatre is connected to Beosound Core via RJ45 Powerlink. The Beosound Core is part of a Beosound Shape setup that has 2 amps. So: TV ---[HDMI ARC]---> Theatre ---PowerLink (RJ45)---> Core---Shape (2 amps)   The issue Audio is out-of-sync between Theatre and Core/Shape by just a few milliseconds. Dialog produces an echo similar to an echo producted in an empty medium-sized room. Audio between TV and Theatre is fine where audio is synced with TV. I've attemped to address latency with the following:
  • Theatre: Adjust latency by reducing latency in the Beolink Multiroom setting to '0'.
  • Core/Shape: in the Shape configuration > settings > BeoLink > Sound Synchronization is set to '0' delay.
While those settings reduced the initial latency, but the audio remains slightly out-of-sync as described above. Any recommendations to further try to remediate the issue?

There is no Powerlink input on a Core…..you can not connect a Theatre and a Core using Powerlink! MM

Thanks all! Finally had time to work on this project again. So to clarify, is the PL connection on the Core only used for output and cannot be used for input? (As an aside, connectivity into amp was first approach but running into other issues that I'm trying to sort out)

Solved! The Theatre and Shape are now working in tandem. I haven't come across a unified set of instructions--it's scattered across a few articles--so documenting the steps below: Place each amplifier in Master mode

Factory reset Beosound Core (or start with a brand new Core)
  • Plug-in Core USB cable into the (first) amplifier.
  • Amplifier light should turn-on with a white light. If that does not happen within 3 minutes, unplug and then plug-in amplifier.
  • Connect RJ45 cable from Theatre to the Power Link socket in the amplifier.
  • Repeat this step for each amplifier. I did a factory reset for the Core for each amp, which may be unnecessary.
    • Add Shape to Connected Speakers
    • Unplug any USB connection from the Core to the amp. Only connection to amp should be the Power Link from Theatre and power for amp.
    • Go to B&O app > Theatre product > ellipses (upper right) > Connected Speakers.
    • Add BeoShape speakers. Confirm proper functioning during the audio test.
    Re-run or create new Listening Positions
    • Re-run existing or create new listening position that adds Shape speakers.
    So, do you operate the Shape without Core attached? If yes: then the Shape amps & speakers are solemnly used as Theatre speakers. You are  aware that the amps do not get sw updates that way? And if you want to change something in the setting of the Shape, you need to reconnect the Core. If no the Core is still connected; then you have incorrect settings for the Shape amps and presumably one amp will not work as supposed. Still the best way to connect the Shape as speakers to a B&o TV (including Theatre), imo, is the described method in the attached file by MM and mine previous posts.
