Wiim ultra connections

[Rotiv]

Good afternoon, greetings to all forum members. This is my first post, I thank you in advance for your help.

Besides my stereo sound system, I have a Yamaha YSP5600 soundbar with an SVS SB2000 PRO. I recently bought the Wiim Ultra Streamer and I want to take advantage of the room correction available in the Wiim App.

I will connect it as follows:

TV HDMI eARC > Wiim HDMI ARC > Wiim Optical Out > YSP5600

Is this the best option?

Regards

I used MMM measurements, UMIK 1 with Pixel 8 Pro.
20hz to 300hz
I'll compare it to REW later.

I wonder what causes the boost above 1kHz.

Yes, supposedly it shouldn't happen, I'll make a few more to see if it holds up.

I ended up trying the Roomfit 20Hz to 20kHz, I haven't compared it to Rew yet. For now it'll stay like this, I'll try to improve the frequencies between 40Hz and 50Hz with the subwoofer's position.

I was messing with the subwoofer volume and forgot... time to measure it again.

The distance between the bar and the subwoofer is one meter. Can someone help me understand why the delay values are so high?

There may be audio delay with the soundbar.

 

[Rotiv]

After several listening tests, the delay that WIIM defined between the soundbar and the sub never seemed correct to me. The sound was out of sync when watching a movie, and several attempts with the sync audio didn't work, the bass is also out of sync with the rest of the spectrum.

I ended up trying manually, since 1 meter equals 2.9 ms and
the SVS SB-2000 Pro introduces a digital processing latency of approximately 6 ms, I tried 9ms of delay.
The sync audio is now corrrect and the bass much better.
Perhaps the excessive delay detected by WIIM is due to the fact that it's a Dolby Surround soundbar and not a pair of conventional speakers...

So are you saying that the excessive delay measured by WiiM isn't present?

Yes, from what I've researched, 157 ms is equivalent to approximately 43 meters off distancie between the soundbar and the sub.
As I mentioned, it sounded quite strange.

I ended up joining the beta, I tried the synchronization again, this time with the Umik 1 connected to the mobile phone.
I still haven't figured out if the sub synchronization is done with Wiim's microphone (I read that they advise placing the Wiim in the listening location) with the mobile phone's microphone, or if the Umik is recognized as the main microphone.
This time it went to a delay of 81ms.

I performed several tests with RoomFit, B&K curve, Pixel 8 pro, UMIK 1 MMM measurement, sub crossover 80hz, 1/12 smooth, 20Hz - 400Hz.
Considering it's a soundbar with a subwoofer, I'm quite satisfied with the results. When I can, I'll compare it to the Rew.

Regarding post number 30, forget it. I was making things up and ended up going back on it.

If you place Umik 1 in another location and measure it to see if the delay changes, you should be able to determine whether Umik 1 is being used for synchronization.

The RoomFit results look good, but I think setting the crossover to 100Hz–120Hz and increasing the sub volume a bit more would eliminate the need for RoomFit boost.
(However, if the subwoofer is not centered within the speakers, raising the crossover frequency too high may distort the stereo image.)

 

[Rotiv]

I'll follow the suggestion.
The sub is in the right corner.

Post 20 when I had the crossover at 200hz, measured without MMM. No boost in equalization.
With MMM measurement, the bass is read very differently...
I changed the crossover to 120hz and increase volume 2db in this new measurement.
I'm tempted to stretch the equalization up to 800hz??

MMM is more susceptible to noise in the room. It should be performed in as quiet a room as possible. Could sounds from appliances like air conditioners or refrigerators be affecting the measurement? When performing RoomFit, you may want to try increasing the volume slightly.

For now, why not create RoomFit profiles with crossover frequencies of 80Hz, 100Hz, and 120Hz as they are, and compare how they sound? Ultimately, choose the profile that sounds best to you.
