Hello,
I've connected my Tv headphones output (not B&O) on Aux input BO 5 Encore. My goal is to watch concerts or movies with Beolab 8000 quality sound. Each input of BO 5 Encore works well, but then I use Aux input, there is a significant sound delay (almost 0.5s) compare to TV sound. Therefore, image and sound are not synchronized and it's really significant.
First, I thought delay was on hearphones ouput, resulting D to A transformation. I checked it with another sound system and it works well, no delay at all. TV sound and hearphones output are totally same.
After that, I thought reason was cable lenght betwen TV and BO 5 encore, so I checked with a shorter cable but result was identical. Transmission delay from 5 Encore to loudspeaker cables is non significant.
So, I deduce 5 Encore apply a delay, wich I don't understand why. Logically, analog signal must be pre-amplified without D to A conversion (instead of another inputs) so no delay must be apply. I haven't service manual with diagram to confirm that and I have no idea of how fix it.
My question : is it a BO 5 encore known problem ? In case of, is there a solution to reduce this delay ?
Thx for your help. Regards.
