ANC turned off by default?

[rugedraw]

ANC Is only in certain applications. The ACM has the ANC calibration. Not all ACMs have the ANC calibration.

B&O only For 2.7, 3.5 and PowerBoost has ANC.

No 5.0 has ANC B&O or not

The ANC bit in the ACM 727-04-01

and in the DSP

When you say B&O, is it specific to both regular and unleashed or only one or the other?

Unleashed for certain. I believe for the 8 speaker also.

Because its in the ACM calibration. There are two additional software fields that are for ANC.. Its not a turn it off situaiton

So you are saying that it works even if the other two options are disabled?

Thinking thru this...

1. If it requires mics, which I'm not sure why it would not, and the mics are disabled, I don't see how it can be active.
2. If it is disabled in DSP, I'm not seeing how it can be active.
3. If I disconnect power to the DSP and there is no noise difference, I'm not sure how it can be active.
4. SGS has installed numerous systems in these trucks and not changed anything in the FORScan settings with zero issues. If it were active, there would be issues. Perhaps since they removed the DSP, that eliminated the possibility of issues, assuming the ANC is in the DSP.

I will disable the ACM calibration if it is not already set to "0" (which is the default), but I am going to bet a coca-cola in a 6oz bottle that it doesn't change a thing from where I'm at right now.

I’ll be leaving this thread

you don’t seem to understand that thedsp doesn’t power every single speaker. The acm still powers a few but I’m not going to argue about it.

What the hell do I know

I had no idea that F150 gen 14s had ANC. Is my 2022 2.7 enabled by default?

Just FYI, my lariat with unleashed has zero microphones in the headliner except the voice mic over the driver.

Also, none of my wiring diagrams have anc mics shown for any level of oem system (my diagrams are somewhat specific to my vin, but show all audio options from 4 to 18 speakers). Which is why I assumed it was just an algorithm.

Now, the highbrow platinum may, lol.

I'm not arguing with you ... I just listed some thoughts and stated some observations and opinions. Did not mean for anyone to get offended over it. I do understand the DSP does not power the rear speakers and tweeter speakers, but from the wiring diagram I viewed, every microphone is connected to the DSP. Now... if the ANC can work without a microphone, it's doing some magic that I've never heard of. But hey... what do I know either?

Does anyone know if this “active noise canceling” is really active or just an algorithm in the dsp?

where the mics? What color wires are going to them?

It’s not active noise cancellation, it’s active noise control… it’s not intended to cancel out non cabin noise, it actually injects a “throaty” engine noise INTO the cabin so your non-V8 sounds more aggressive. It’s stupid and based off old machismo nonsense. I bought a $60K truck for the function and luxury. I don’t need to pretend I’ve got a loud engine. It’s powerful enough without having to brag?

I think that is the Fake Engine Noise that you can turn off here:

With mics installed (3 in various locations in the roof) the ANC should be designed to pick up undesirable noises and send out of phase frequencies to defeat the noise. In my 2020 Ram is used the subwoofer and door speakers to defeat low freqeuncy exhaust and it was very noticeable when you bypassed it. So much so, I would not drive the truck without the ANC active, as the noise was a serious nuisance for me.

@Sonnie, Have you talked to the guys @SoundsGoodStereo?

@Sonnie, Have you talked to the guys @SoundsGoodStereo?

Yes... and I was told they don't change any ANC settings on these Ford systems and have not had any issues with the ANC.

And another vendor on this forum also said he'd not heard of anyone having any issues with ANC.

When you are running any type of interface, like the Zen A2B, you are removing the factory amplifier and the ANC does not apply anymore. Keeping the stock amplifier, the ANC is programmed on the Unleashed trucks and it's not a microphone, but rather an electronic algorithm that Ford came up with.

Those aren't mics, they're ultrasonic sensor locations for in-cab movement on the security system. There's a mic for the driver, the others detect hands in windows as well as other movement. I threw a wadded up T shirt into a half-down window and it set off the alarm.

Explains why you guys told what you did, that you haven't had any issues. This is good info to know.

I did change the following to "0", but again, can't tell that it is introducing any noise. DSP is still in use at this time.

It does, however, cause the rear speakers to pop when the phone rings... so I'll change this back to "1".

This also explains why the mic 1, 2 and 3 entry are off in FORScan, if there are in fact none installed. What is interesting is why ANC was already disabled in the ACM.

Interesting. Someone else claimed they disconnected that mic above the left rear door (mic 3) to disable his ANC. Another interesting discovery is that I remember seeing a small grill cover above the left rear door in the headliner on my FX4, but it is not there on my 4x4... same Platinum other than the FX4 package.

@Sonnie put your windows down and arm it. I think it takes a few minute to fully arm and then waive your arm inside the truck to see if it goes off. I know my MME is pretty sensitive, it also asks on shutdown with the door closed if I want to disable the motion sensors.
