After the firmware update to 3.1 you will be able to connect the device directly to the soundbar for the best Dolby Atmos experience.
You can get firmware here: https://www.helpdesk.nakamichi-usa.c...rmware-upgrade
Nakamichi Shockwafe 9.2 Ultra with 3.1 firmware update.
Peripherals: DirecTV Genie with 4K / Dolby ATMOS, XBOX 1 X, PS4 Pro, LG 65OLED C7P
My findings are as follows:
Center channel dialog sounds "small speaker". Not full and rich enough. I think there is room for improvement there.
Overall atmosphere of SSE/ATMOS/DTS:X sounds great! The dolby ATMOS demo disk shook the house and scared my daughter who thought at 747 almost hit our house. This system loves to be loud.
Subwoofers need a few settings lower. Watching movies at night is a pain with getting text from sleeping family to please turn it down. Unfortunately the subwoofers are as low as they go.
Wish it had wifi or a network port and a app developed to adjust settings with a smart device.
Wish it had on screen display.
You are told to connect DirecTV or other sat boxes directly to your TV and then send sound from TV to soundbar via HDMI/ARC
When doing this you get lip sync problems that can not be corrected. The lip sync adjust on the remote only works, according to the manual, with optical and coaxial connection. NOT with HDMI/ARC. Thus you can't fix it and I tried anyways.
To resolve lip sync issues you must connect DTV directly to the soundbar. But this introduces other issues.
*Update- Forthcoming firmware will address the following:
((1) It will not negotiate or pass along confirmation of 4K so when going to a 4K channel it claims the TV does not support 4K. You must go into DTV settings and re-check the box for 4K under TV Resolutions. EACH TIME. Takes about 30 seconds but annoying. 2) When rewinding or fast forwarding DVR content the sound will sometimes, more often than you think, drop off. You must switch HDMI ports from current selection to a different one and then back again to get the sound to return. Nothing else I tried works.)
HDMI/ARC from TV to soundbar will does not support ATMOS. So if you have any content with ATMOS coming from the TV side of things to the soundbar will not work. This also can be found when using any WebOS app on the TV such as Netflix, Hulu, Amazon Prime Video, or Plex.(these are the ones I tested). Thus when you select a movie that has ATMOS on the Netflix app, for example, the app does not see ATMOS and turns it off. I tested this by going with internal speaker which supports ATMOS (my tv has atmos on its own) and the content played fine in ATMOS as well as had the badge on the movie information screen. However going back to HDMI/ARC the badge disappeared. I am not talking about the pop-up badge on the TV, I am speaking of the badge on the movie selection on Netflix that tells you what the movie had. Eg, Vision, ATMOS, etc. This is due to eARC not supported by the soundbar so compressed ATMOS is not allowed. The ARC/HDMI port only allows something like 1Gbps allocated to sound where the rest is for 4K video. So the limitation is in the physical port not the cable. Upgrading to a higher bandwidth cable for ARC communications will not solve the issue. This is a bummer since I believe the future is all about smart TV's and you should be able to play ATMOS supported content using the apps on the TV. My LG for example even has a Dolby ATMOS demo app which is useless with this soundbar.
