autogain on bose 700 soundbar
Trying again, since my last post went unanswered after 2 weeks. I have purchased a Bose 700 Soundbar + Bose 300 Acoustimass module. With music it sounds great, as it does on "most" TV/movie contents. Why "most" ? Because on all quiet passages in movies and TV series a strange phenomenon is taking place: the background noise is greatly enhanced to the point that it makes all the speakers and the sub producing some kind of hissing white noise. As soon as one of the character start speaking, the system seems to correct itself, only to go back to the previous, unnatural sound as soon as character finished speaking.
I've been able to observe this on both Dolby contents and Stereo contents - with the latter seemingly more affected. Some examples are "Better Call Saul" and "Handmaid's Tales" - but any dialogue-heavy contents will feature the same issue, regardless of how the soundbar is connected to the TV/bluray player.
Needless to say, this is extremely annoying - especially given I'm in a situation where I cannot return the soundbar (having purchased it at a normal brick and mortar shop). The issue affects the sound quality so deeply that, when it occurs, my TV speakers are far, far better sounding than the soundbar. I'd say, without exaggerating (sadly) that in such circumstances, even my mobile phone sounds better than the Bose 700.
This problem is not new - it has been reported before for the Soundtouch 300  - just read this excerpt which basically describes what I'm hearing:
"The auto gain on background noise I noticed before adding the surrounds however and it is particularly bad. My other half was watching 50 shades of grey on Netflix the other day, a particularly bad film but also one with a lot of dialogue, and whenever there was a pause between the characters speaking there was a really loud background hiss which made it sound awful. Granted, this is a lot to do with the shoddy production of that film and it having a particularly bad soundtrack but the Bose just amplified it meaning it actually sounded better on my normal TV speakers."
Is somebody from Bose going to comment on this particular issue?
