On my G12 11" QCM6125_20240111-1739, the Cut frequency in amplifier is off by 10X
If you set 60Hz It crosses it over at 600Hz
If you set 80Hz It crosses it over at 800Hz
If you set 120Hz It crosses it over at 1.2KHz
System update does not report that there is an update available.
What is the solution for this?
@Ryan Williams
Hello.
If possible, could you please record the related video then send it to us?
So that we can learn the specific situation and forward it to our technical department for further advice.
Besides, please tell us about your amplifier is factory or aftermarket.
And please go Settings > About Machine,
then send the following clear photo to us: Build Number; MCU version.

This is for the speaker output. The subwoofer will be added later. There is no amplifier.
Here's the video.
Please understand that while the feature is cutting the bass, it is cutting it at the wrong frequency. Whomever wrote the software somewhere added a zero into things so it does things at frequencies that are higher than they should be.

Hello.
Based on your video, we'd like to tell you about it is the normal situation.
About that settings, it mainly reflects in the difference between high and low notes, not in the volume.
For example, when you set to 120Hz, it will adjust the high frequency signal to the maximum and only the treble is output.
On the contrary, 60Hz will output bass only.
We suggest that you can try to turn the volume up to further verify the difference.
@Support Dasaita Yes, I understand what you are saying, This setting specifies how low of bass is allowed to go into the speakers. 60Hz will play 60Hz - 20KHz 120Hz will play 120Hz - 20KHz.
The problem is that the frequencies you select are not the settings that it works at. 60Hz is appoximately the same pitch as the buzz of electricity...and 120Hz is one musical octave above that.
It is crossing 600Hz to 1,200Hz because someone made an error in the software, adding an additional zero.
When you set 60Hz you get 600Hz - 20KHZ
when you set it to 120Hz you get 1.2KHz to 20KHz.
Listen to the sound when I make the change it is clearly operating at frequencies much higher than I am setting.
I really don't want to have to play pink noise through it and show the output of an RTA to prove this to you, but I do have the equipment to do this. Please create a ticket to get this fixed.

Is there anything in the release notes that indicates this will resolve the issue? I don't want to go through the trouble of completely reloading the unit if it's not going to fix it.
The way to verify this is to play pink noise from a wav file, and connect the output of the speakers to an audio RTA (Real Time Analizer). As you make the setting change you will see a shelf appear at the frequency of the crossover point. When you configure it to 80HZ, you should see the shelf there. There are phone aps that can do this too.., but phone microphones aren't amazing.

Hello.
If possible, we hope that you can try to finish the update operation at your convenience.
Upon checking, your current version still is the original one.
We've been optimizing the software to ensure a better user experience.
In order to avoid this issue is caused by the old software, please give it a shot for the latest firmware&MCU.
Thanks for your time & cooperation in advance.
