Hi Wiimer
Mhhhh .Don’t know, but the dancing bars in the Ultra and what you hear does not match. More. Is it useful to have 25 Hz? My B&W are 48 - 28.000 Hz.

The lower limit for the Topping analyser is 50Hz.



The lower limit for the Ultra is 25Hz.


Ultra displays lower frequency bands than Topping, so the height of the leftmost bar is lower than that of Topping.

I did not mention the bar delay.

Matters system to system. My sub plays flat down to 14Hz, so only adjustable Spectrum Analyzers reaching down to 10Hz are any use to me.

Could you implement a HDMI screen off option? The spectrum analyzer is great but not when watching movies in a dark room.

The screen can be manually turned off.

In addition to that we are awaiting WiiM to allow individual screen options for each input. Maybe as part of the coming Sound Profile options?

Been asking the same thing, but not sure if this is already in the works/brought to their attention?

Time to do some proper feature requests

Hail!

Yesterday I got wiim Ultra

I can't install the full version

 

[Saponetto]

@Alfi It seems that the update did not end well.
My suggestion is to do a power cycle, wait some minutes, then reboot and retry the update... if still is a no-go, best if you open a feedback request through the WH app.

 

[Alfi]

@Alfi Похоже, обновление закончилось неудачно.
Я бы посоветовал выключить и снова включить питание, подождать несколько минут, затем перезагрузить устройство и повторить попытку обновления... Если это по-прежнему не поможет, лучше всего отправить запрос на обратную связь через приложение WH.

Thank you

Rebooted

All firmware versions are gone

After 10 minutes, he reappeared on 24.11.25

And it gives an error again(((

I'm asking you to install version 52736552, but a new version has already been released! What should I do?

 

[Saponetto]

Я прошу вас установить версию 52736552, но уже вышла новая версия! Что мне делать?

Firmwares are sequential.
You cannot update to the release 5.2.738432 until you complete the installation of the previos 52736552, so my humble opinion is that it is mandatory to ask @WiiM Team for a solution, filling the feedback form within the Wiim Home App.

This is the current safest way,

@WiiM Support can direct to him an older FW version.

...@WiiM Support[/USER] can direct to him an older FW version...

Yes, it's the only escape way for @Alfi to get back a fully operative device.
