Just installed the Q990C soundbar to my QN85B QLED TV. I started to use the dolby-test-tones_7_1_4.mp4 file to calibrate my system. I am playing this file through a USB flash drive attached to my TV. I noticed that the Atmos channels are heavily mixed on the Q990C soundbar. This mixing occurs in standard and adaptive mode and with or without Q Symphony. When I talk about right and left speakers, please assume the corresponding right and left sides are used correctly.
I wanted to know if this is normal or do I have a setting wrong.
Front R and L: Front speakers and front height speakers are used
Center: Just the front center speaker
Sub: just the sub
Wide R and L: front sides and the rear sides are used. I am pretty sure that the front diagonals are not being used here.
Rear R and L: front sides and the rear front and side are used
Front Height R and L: Front Height and Rear Height speakers are used
Rear Height R and L: Front Height and Rear Height speakers are used
So I get #4, its mixed to create the wide channel although i would think the diagonal front wide speaker should be used instead. But I find #1, #4, #5, #6 and #7 to be odd. Also I have never heard the diagonal (wide) front speakers being used in this test track.
Update: A person on reddit suggested that i hold the down button on the remote until the system updates the satellites and checks all the speakers. Not a fw update but it somehow updates the settings on the speakers? The behavior has now changed quite a bit.
standard mode - front wide now being used but not any sides.
Front: no longer uses front top. just the front speaker
Side surround: Uses Front wide and Rear Front. Front and Rear side is now no longer used
Rear surround: Uses Front wide and Rear Front. No sides like #2
Ceiling - Front top and rear top still used in all 4
Adaptive mode: enables the front and rear side speakers which wasn't used in standard mode???
Side and rear surround: Uses Front wide and side. Uses Rear front and side
Craziness. but at least all the speakers are being used in adaptive mode. So I guess I use that mode
