If you are already using the CINEBAR PRO at home and subsequently purchase the EFFEKT rear speakers, it is possible that the firmware on the CINEBAR PRO is not yet suitable for the commissioning of the effect.
Solution: Update the firmware of the CINEBAR PRO BEFORE commissioning/pairing the effect speakers.
