But seriously, there must be a way to turn down the volume of that sound a bit. By firmware hack/mod? Of maybe we should just ask DJI? I personally like the sound but it's WAY too loud. I can never power the thing up in the evening at home (for config or something) 'cause I'll definitely wake up the kids.
Phantom 2: Can I mute the startup song?
- Thread starter krb
- Start date
Yes I thought this from day one, no need to be that loud really, I'm 22.5" away from it on startup yet it's heard from a distance.

No hack possible. It's simply not a consideration of design.
The noise is generated by modulating (or driving) one of the three phases at between 20 an 20KHz.
The phase driver is designed to be as efficient as possible to deliver full voltage to the load with near instantaneous on-off switching times.
The volume is determined by supply voltage, in this case the LiPo, and to a lesser extent the efficiency of vibrational transfer from the motor to the surrounding materials (the Phantom).
Since the ESC can only control frequency and not amplitude there is no 'volume' adjustment possible.

Must of been a tricky thing to set up at design, you would think a little computer speaker would have been to easy, ah well.

If you truly read the entire thread then you must have missed this post from December:
"The ESCs send signals to the motors which vibrate. Brushless motors work on 3-phase power and it's pretty easy to make them vibrate at any frequency. The Naza tells the ESCs what to do.
The same tune is played no matter what ESCs and what motors you have"
Which part of that are you struggling with?

i sure a mod sees your posts and kicks ya outta here. most of your posts are just talking down to people, don't post unless you have a helpful post, not to demean people.

It's too bad that your panties are bunched up.
Facts are good. The fact is that you either didn't read the thread (as you claimed) or you could not comprehend what you read. Either way, you have been helped by my posts.
Even if you are too caught up in your own mediocrity to see the truth.
Well, since we can't possibly mute it... can we at least change it? :lol:
