What does Mekede DUDU sound like something a toddler does in their pants?

The video input is pretty cool. It could be nice when demoing your system to have a video of the performance playing.

 

These say they are running Android 13. If that is true, that means the digital output bypasses the Android system that degrades hires audio and sends a clean signal to your DSP. One of these will be my next head unit.

 

One of the main reasons that I am excited about this!

 

I have one, and generally think it's a great value. I am using the optical output to my M4 DSP, and I'm having a couple issues with output that I'm trying to chase down. The digital outputs are not "full volume" so you'd need to increase the input gain on your DSP. When I do that, I'm seeing clipping and distortion earlier than expected when playing music through the Tidal app - but not seeing any distorition when I play test sweeps (which are locally downloaded files.)

I did make sure that Tidal didn't have "volume normalization" or anything else running. Unfortunately I struggled to find any files on Tidal that I could use to test a 0db output for clipping.

I tried the USB audio out, using a DOUK U2. It was louder, and got a true 96k out. The biggest issue was that the android head unit would only send some media out via USB, other apps seemed to be muted. So only VLC (for movies/media) and music apps like Tidal worked - but I had no audio output over the USB when I played bluetooth files from my phone. I recall some issues with the phone app as well, but I can't recall exactly what the issue was right now.

I ended up returning the U2 and switching back to the dudu7 optical out port, and I'll live with the low output.

Overall I still think it's great and recommend it.

 

Great input. Would you be willing to test the usb input? I have a surface pro and want to plug usb c to the Mekede usb c and as long as I can see the surface pro display on the screen like a computer monitor, I think it will meet my want/need. Obviously having audio will also be helpful too. Most of what I want to do does not require audio though.

I am going to bet that your audio issue may be hidden in the device settings. Many android devices have a ton of flexibility but the settings can be buried in the menus.

 

Another video with sound.

Hpw do these mount to the car, Is there some kind of mounting bracket?

 

They usually have a bezel that fits your exact car but my vehicle is 1972 and the other is a 1976 so I do custom mounts that I fabricate.

 

Mine has a single din opening, so not a bezel per se. Could still be possible?

 

Perfect timing for this post. I ordered a Dudu 7 12/256 to replace the cheap non Mekede Android 4/64 HU i am currently running. Will be interesting to see what kind of differences there are between the two.

 

I am not sure this unit can do anything my Joying cant do, except this thing can play the hires audio without downsampling. Thats a decent price tag for that one thing. Ill need to see some youtube reviews to see if I want the upgrade down the road. good thing is if I do get it, I can put the Jying in my truck, and then move my pioneer from my truck to our suburban which is still using the factory radio from 2006.

 

I've seen a few reviews of the Dudu's and they look compelling, but they might need to hire some marketing people to do something about the name. Hard to take it seriously with a name like that.

@ndm If you get one, do a review.

 

Agree that the name is unfortunate (and they have been around for a while) but the product is solid.

 

They claim 96/192 for optical & coax. I'm not aware that anyone has put it to the test. I remain skeptical of that. I have the 512/12 model, but it'll probably be a couple months before I can get it installed. I will be running optical, coax, & USB to the DSP so I can try them all. Now, if their claims are true & they have actually been able to implement it, I'm not sure of how I'd be able to verify what sampling frequency was arriving at the DSP. I got this HU for several other reasons, and just view higher sampling as a bonus.

 

I'm not expert in Audio, but I have heard Helix DSP can analyze incoming signal.

 

Delete...wrong thread

 

Any update on the optical output to dsp? Curious if the firmware updates fixed any issues.

 

SQ perspective video!

 

I can snap you some pics, besides pics of the screen off, do you want a picture of dark content on the screen, like a dark movie with bright colors or an all together dark scene? My kids love to watch movies in my car.

 

Yeah, it will be great. I want as many photos as posssible. Blacks beside sharp whites reviel light bleeding. Which is big weekness of QLED (IPS) displays.
Just black screen with white text will be great.
I don't need it for movies. Only static pictures (menus) but with decent "black" for night ride. I hate that grey glowing rectangle (screen). 😲
Also photo of screen when car is off is easier to make. That part where display meats frame (area of 10cm).
Thanks in advance for photos. 🙏
