I'm curious of this also, and if it improves RCA voltage beyond the crappy 0.5v.

---------- Post added at 04:51 PM ---------- Previous post was at 04:47 PM ----------

I’m curious of this also, and whether it improved the rca voltage from the poor 0.5v the joying RCAs give.

Sorry for double post, first one didn’t quote the previous message.

So if using an external DSP, what settings on the head unit should be toggled?

also, what is the sound conditioning setting?

and on the external amplifier, do you set the crossovers to flat?
[Android Head-Units] WishiHadAnR32:
Which setting in the system is it to turn on and off please?
[Android Head-Units] rigattoni:
Just switch off external amplifier in the settings.
[Android Head-Units] thefallen924:
By any chance, do you know how to toggle the external amplifier setting via tasker? My external amp powers off after about 10 seconds of shutting the car off. problem is if i stay sitting in the car, and turn it back on, the amp wont power back on. if i toggle the external amp setting, it'll power the amp back on. so my plan was to set up a task to toggle this setting via tasker, so I dont have to manually go through the settings in such a scenario. I did find all of the system/global/secure settings, but cant seem to identify which one is for the amplifier.

Does the EQ in the android OS work when using the optical audio out port on these?
[Android Head-Units] Tricky13:
Just to reply and resurrect this thread, yes some of the audio controls work when connected to an amp but not all,

Also, has anyone who is using the optical output have any problems with audio drop-outs when playing video files ?

This is the model I bought, but with the IPS 2.5 D10 inch screen (JY-UOS08N4G)

https://www.joyingauto.eu/new-intel...-din-7-inch-head-unit-built-in-4g-module.html

I am pretty sure there they sent me the wrong one, no digital out, if you look at the picture at the bottom of the page, the digital out is sticking out with a yellow caox connector, mine does not have that.

I also bought this USB rotary volume knob from amazon, was hoping it would work, but could not get it to work. It shows up as a virtual keyboard, but the volume does not respond when I turn the knob:

Hawe anyone got root on these new intel? I hawe JY-UOSO7N4 9inch version
[Android Head-Units] strawsy:
I enjoyed the review. Thanks for taking the time. I liked that you covered the technical stuff and didn't just swipe through screens and a few apps like most people do. I was hoping the one you got would have the 4g module built in but I didn't see it. I emailed them asking if they had one with spdif and 4g. I doubt they do but we'll see what they say when they get back from their vacation. Your review has persuaded me to buy one. I was planning on going with normal rca but it seemed like digital was louder and cleaner from the video. Have you tried Spotify or could you try Spotify? I didn't notice that in your video. When do you plan to install in your car?
[Android Head-Units] checksum123:
Great technical review!!! Thank you for all the details...

I just finished installing mine, I agree the sound is nothing short of amazing, I was awe by the clarity, no hissing or noise. The DSP brings all the sound details to live, so many settings.

My amp is only set to around 15% gain, but it is still very loud and clear.

I have a SUB, but it is not connected to the unit yet, I have it connected to my amplifier through the rca pass-through. Will try to connect directly to the unit and see if it makes any difference.

To really get the most of of this unit, you definitely need to pair it with an amp and a subwoofer.

The DSP has so many settings, I wish you could save the settings, that way you can set it with one touch, like setting#1,#2,#3,etc...

Definitely go get you one, you will not regret it. IMHO the RCA out paired with the internal DSP is good enough. I would try the RCA out first and see, I don't think you need the digital out, for me it just adds additional components to the setup.

Hopefully they won't flag my videos due to copyright music I was testing...
[Android Head-Units] strawsy:
They flagged the video 1 so I'm sure video 2 is coming next. I was going to try the rcas but the .5 volt has me worried. I know my amps and I will probably have to turn my gain up halfway or more to match that voltage. It will probably introduce a hiss or whine. I might just order everything and if I don't need it send it back. I hate doing an install and having to wait to finish.

Does your unit have the 4g module?
[Android Head-Units] checksum123:
Yes, I saw that @19:00 , it was 0.5/0.7v. That had me worried too. Maybe this is something we need to feedback to Joying.

Before I had another Joying unit, that I connected to Clarion Equalizer, and that fed a nice 2.0V waveform to my amp, and it was really loud, but I noticed a lot of hissing when not playing music.

The way it is right now, I might have to increase the gain of my amp, since it is only at 15%, i will have to play with it. But I can tell you it is really loud.

The only issue with these joying unit is reliability over time, the last one I had had a mind of its own and kept rebooting out of the blue. Will see how this one holds up.

I saw that Joying rotary volume knob, but I do not like the bluetooth ones, they have a delay and use a battery. I would rather have a USB rotary knob.

Sub level is very weak
[Android Head-Units] strawsy:
That's what I was afraid of. That's why I was planning to go digital.
[Android Head-Units] strawsy:
I found a model(EU-JY-UOS03N4G)that has spdif out and 4g module built in. It's only a 7" display but I'm hoping they have a 10.1" model. Waiting for them to reply after the Chinese holiday. That's the one I will order if it exists.
[Android Head-Units] checksum123:
I am pretty sure it has a 10inch display. Since the display is separate from the unit, you can pretty much add any display size to the unit.

I would go with the IPS display, much nicer looking. Only thing, it does not have any touch buttons.

Can anyone recommend a good DAC

Something that would not break the bank and small enough to fit inside my glove box.

Also, how would you control the volume if you add a DAC? Through the DAC or the unit itself?

Thanks
[Android Head-Units] guimond47:
I did try spotify in a video and worked just as well as amazon music. there for i didnt wanna make the video to long.

there is one with a 4 G module, here is a link to all units available with DSP coax digital pre out, maybe u can find one there with a 4g module. the RCA was not as loud because its analog voltage.. cannot be compared to a digital source. the digital really made my speakers sound amazing on rock and high instrument songs.

https://www.joyingauto.com/catalogsearch/result/index/?cat=7&q=intel&product_list_limit=30
[Android Head-Units] guimond47:
why do you need a DAC? im confused here. also even tho the sub is not as powerful for voltages its fine....

amps have a Signal noise ratio between 95-120 db now days. cranking the gain to match the voltages wont affect anything. subs dont need "clearity" as much as speakers, thats why their voltages are higher on speakers.
[Android Head-Units] strawsy:
I will find if they have a 10.1 model ready to go but if not I will ask about swapping to the 10.1 ips. I don't care much about buttons. Plan to use steering wheel controls. I plan to use something like this https://www.amazon.com/Musou-Digital-Optical-Converter-Adapter/dp/B01AWBA8U8.

I'm going to buy the Dayton Audio DSP which does not have spdif in. So going to convert digital to rca with adapter like the above, then into the dsp. I want to avoid using rca out on the joying because I know in my vehicles I am susceptible to noise if my amp gain is too high. I can avoid this with the spdif out.

---------- Post added at 07:34 PM ---------- Previous post was at 07:31 PM ----------

I think he wants a DAC for the same reasons I mentioned in my reply. You're right about Snr for subs but I have experienced noise when my sub amp gain is too high, so I will try what I can to avoid having to crank the amp gain.
[Android Head-Units] guimond47:
line drivers.... or get a dsp. the rockford dsp has a digital coax input and 8 volt preouts i believe. check it out here : https://www.amazon.com/Rockford-Fosgate-8-Channel-Interactive-Integrated/dp/B076CY59YX

Its the cheapest dsp with coax input.....
[Android Head-Units] guimond47:
i would not do a dac to analog, it defeats the purpose of digital output.... Get a nice dsp, you wont regret it.

[MENTION=1824007]guimond47[/MENTION],

Sorry, I meant DSP

I watch a video review of the Rockford Fosgate DSR1, and I am leaning toward that one, based on price/feature (being able to configure via bluetooth is a plus). And yes, it does have a coax input, also you can use their remote level control to adjust the volume, on one of his review he said you can control the main volume or source ( https://www.amazon.com/Rockford-Punch-Remote-Level-Control/dp/B00BNXZGXO).

https://www.youtube.com/watch?v=39lRIuH4cRM

[MENTION=1007777]strawsy[/MENTION],

Why not get the Rockford RS1? That way no need for any converter.

This is the first time I am using a DSP, so not much experienced, just want to experiment a bit.
[Android Head-Units] strawsy:
I will get the dsr1 one after looking at it. I didn't realize it had coax input. It was between the dsr1 and the Dayton audio dsp but Dayton dsp was cheaper. Dayton audio dsp doesn't have coax in but now that I know dsr1 has coax I will get it instead. I'm looking for highest sound quality with lowest cost. Right now I have a jvc kw_m730bt and sound quality is fantastic so trying to not downgrade on Sq.
[Android Head-Units] guimond47:
Ya the rockford will be a great combination with joyings headunit. I also found tidal HIFI for 60$ USD for life time subscription. I bought it and it works great! HIFI quality is at 44.1khz rate which is perfect for digital output.

That seems too good to be true. I know it will work at first but not sure it will last forever.
[Android Head-Units] checksum123:
Just placed an order for the DSP, should be here thursday and will be able to test it out this weekend. Good thing is that it is small enough to fit on top of the joying unit ( at least I hope), this will make installation much easier as I won't have to move a lot of cables around. Just add the coax cable and move the rca from the joying unit to the DSP, and also find +12V and ACC, which I already have.

I don't think I really need it, but you guys convinced me to get it, will see how big of a difference it makes.
[Android Head-Units] juandhi:
What about the snappiness, speed of the unit, is it noticeably less laggy etc?
[Android Head-Units] strawsy:
I don't have one yet but I don't think speed has been an issue for a while now. Even some of the cheaper ones are pretty quick. Unless you have a unit with 2gb ram or less speed should not be an issue.

would you guys mind giving an update when you get your units installed? guimond47 and checksum123.
[Android Head-Units] MIndrunner:
Speed is much better then any of other CPU versions out on market (PX5 /PX6) . This is an Intel Airmont 64bit on 14nm done by Spreatrum, SoC 9853i. It runs at least 30% faster then Rockchip (px5/6) that are built on 28nm techology.
[Android Head-Units] guimond47:
I have the unit installed in my truck, blown away by the difference the coax makes. it makes the vocals shine in clearity, the mid bass is super smooth and responsive. Dont regret this setup at all. Heres a video on how i set up tidal HIFI.

Does Android Auto work with 9.0 Pie phones on this unit?
[Android Head-Units] twokidsandaphone:
Ok, forgive my ignorance, but SPDIF carries only two lossless channels, or 5.1 compressed. The joying I assume puts out just the two? So for sub control/fader control you need to do that at the DAC or how does one do that?
[Android Head-Units] guimond47:
2.0 stereo sound only. then you would run it to a DSP ( like rockford dsr-1 or audio control dm 608) then for fader and such your out of luck, sub control, you can get a remote knob that controls the dsp level out for the sub. I know on the audio control, your allowed up to 4 equalization presets that are controllable with the volume knob, you can set a preset with your rear speakers off if you want to. ( this would be your fader) other then that even myself never fade or balance my audio settings. once its set, you leave it.
[Android Head-Units] checksum123:
So i finally got my DSR-1 today, and could you wait to install it and experiment with it.

One Word " WOWWWWW"

[MENTION=1824007]guimond47[/MENTION], thanks again for all the tips, I thought my sound was good by using just the RCA until I put in the DSP, as you said I was blown away by the clarity and loudness. Before I had my volume around 16-20+ to get it really loud, with the DSP, I only reach around 6+ for the same loudness, and the sound is very clear, very punchy loud bass paired with the subwoofer. I could not be happier with the setup.

The DSR-1 is small enough, I was able to fit it right on top of the Joying unit, next to my PAC (blue in the picture for my steering wheel control). Hook up the digital to the DSR-1, and the RCA from the DSR-1 to my 4channel amp, and the subwoofer RCA to my mono amp connected to my sub.

First thing you need to do when you get the DSR-1 is to update the firmware, then the install is very easy, find a constant +12V, GND and ACC for the remote turn on, and you are all set.

I configured mine as FL+FR+RR+RL (full freq range) + 2 sub with the digital input.

I install the rockford app ( perfect tune) to configure the DSP. I first installed it on the Joying unit, but it did not find the DSR-1 via bluetooth, so I had to use my samsung tablet and it found the DSR-1 right away.

Configuration is straight forward by using the wizard to get you going, then you can play around with the more advanced settings. There are so many settings, I did not understand all of them, but they included a standard equalizer to make it easy. I did not play around with the timing and other stuff, will be playing around more with it.

They also have presets you can save and load or import.

The built in joying eq does work with the digital out, I was surprised, as I thought the digital signal would be unmodified.

Also, the volume level works with the digital out, I thought it would not work, that's why I got the Punch Remote Level Control, but looks like I won't be needing it.

One thing I noticed, I hear a loud pop when I start my car ( scared the sh*t out of me the first time). Both of my amp turn on are connected to my ACC, maybe that's why? The DSR-1 has a remote turn on Input and Output, I will connect them to the remote turn on output on the DSR-1 and see if the poping noise goes away.

I was going to post a video, but I am sure youtube will flag it with the sound I am using to test. i will try to find other songs.

[MENTION=1007777]strawsy[/MENTION], they shipped mine from their chinese warehouse. When I was buying it, they told me that the unit wasn't available yet on their website, but she told me she could ship it direct from the warehouse, came in within 1week via DHL.
[Android Head-Units] checksum123:
So I moved both amp Remote Turn On to the DSR-1 Remote Out, and no more popping sound when I start the car.

My speakers never sounded this good, A+
[Android Head-Units] strawsy:
So previously you weren't using the dsr1 remote out for your amps and now you are. Where is the dsr1 getting remote input? From your head unit? Also is there a pop noise from 1 to 0 like guimond showed in his initial review video?
[Android Head-Units] checksum123:
Correct, before I had it connected to my car ACC, moving it to the Remote Out on the DSR-1 solve the issue.

The DSR-1 is getting Remote input from ACC

I have no such issue, from 0 to 1 or from Mute to 1.

I need to lower the gain somewhere, volume level 10 is very loud. The built-in joying equalizer is already set standard, and I did not make a lot of changes on the DSR-1 setting, I will try to lower it on the DSR-1. The equalizer setting on the DSR-1 and Joying are a little different, the DSR-1 is more granular, and not that linear, a 1db change on the DSR-1 has more effect then if you do it from the joying equalizer.

The surround effect on the joying is really good, it feels like you have a 10 speaker system, it fills the sound everywhere.

When I was driving today, I received a phone call, and it was crazy loud, much louder than the music I was playing. I know there is a setting somewhere in the joying where you can lower the bluetooth volume, but I am not sure if it works with the digital out. Also, the call is heard on all speakers as opposed to only the driver's side, as it was when I was using the RCA.
[Android Head-Units] guimond47:
I would like to comment on Checksum123 Review Setup.

If you carefully watched my review video, you will see I mentionned that the popping noise from 1-0 or mute was STRICKLY twords RCA PREOUTS. The digital Coax Output does not have this issue. It is clean as clean could be.

For volume sensitivity, In my video I DID mention that IF it was too sensitive, you CAN lower the EQ frequencies EVENLY on the joying EQ. This would lower the the volume output. You can also lower the DB output volume for each speaker in your DSR-1. I highly recommend you read the DSR-1 Owners manual or instructions on how to tune, You may be missing a lot of info that would dramatically increase your listening experience...

As for your Punch Volume Knob. - I highly recommend you keep it and use it for your SUB output volume control. This can be programmed in your DSR-1. Reason for this is because the DIGITAL output is only 2.0 Stereo. you cannot control subwoofer output or fader. The remote knob will allow you to control your subwoofer preout volume. That way, you can turn it down or up on certain track you may feel it needs more or less bass.

The SURROUND EFFECT on the joying DSP controls speaker delay. Using Coaxial Output, only the TWO top adjustments (front) will be APPLICABLE. - You can also do this in your DSR-1.

Also your popping noise you experience would fall as normal IF your DSP came on after or WITH your amps. Most dsp's will POP coming on. That is why it is WISE to hook up the amp remote to the DSP REMOTE OUT(like you did afterwards). This allows the DSP to power on first, then turn your amps on.

I HIGHLY reccommend you watch my TIDAL HIFI setup video. You think it sounds good now, Wait till you try a true recorded 44.1khz/96khz recorded track. You WILL be blown away. Also once your dsp is properly calibrated as well.

Other then that Enjoy your headunit! I found installing Poweramp makes a nice combination as well as TIDAL HIFI.

[MENTION=1824007]guimond47[/MENTION] - got a few questions if you have a few seconds.

1- Do you think you can try Neutron Music Player with some Flac files (if you have them). It's a pretty crazy app, think Poweramp on crack. LOL

2- The SPDIF is 2.0 right? Does that mean you need another cable for the sub? I was thinking about using a SPDIF to RCA DAC for that little extra quality. They come with a volume knob as well so it's easier to control.

3- What do we know about root for it?

4- In your video, you said you live in Canada (me too). Where did you get it shipped from? How long did it take? What was the grand total price?

5- Have there been any dropouts with WIFI or Bluetooth? Iv read that a lot of these HU suffer from that.

6- Hows the call quality on it?

7- Have you tried the dashcam or backup cam on it? How do they look?

8- In the video, you tried the Radio but didn't have the antenna set up yet. Did you set it up in your truck? How does it sound? I listen to a lot of FM radio.

OK, sooooooo maybe this will take a little longer than a few seconds. LOL, my bad. I have ALWAYS wanted an Android HU but SQ has been a concern. I REALLY REALLY want this one to be good!!! I wish I could hear one before I bought it.
[Android Head-Units] aerobahn:
Has anyone figured out how to root these new Intel (chip: SC9853i) Joying units yet? Would be interesting to install Viper4Android on them.
[Android Head-Units] surfer63:
You might be disappointed. FYT, who makes the software, has intentionally altered (= crippled) the software layer and drivers so that viper4android does not work on the previous Joying Intel Sofias (after May 2017) and the current PX5s. I would not be surprised they have done the same on these new Intels.

Next to that: it seems you have so much options on these new DSP+SPDIF intels that you would not need viper4android at all. viper4android is certainly not always the best solution.

Of course: that option is only to test after rooting.

My rooting script for Sofia 3GR might work. After all, that script is the simple Android 4.0+ rooting. No guarantees whatsoever. If you are going to try that, make sure you have a clean firmware from Joying. Which means that you have to wait a little longer till Joying releases that.
[Android Head-Units] kouklo:
For me, it's not so much about Viper (don't get me wrong, I want to try it) but more about adblocking. Here in Canada, our data plans are a joke. Ill obviously be setting up a tether from my phone, if I can save a few MB then why not? I have tried a few non-root apps before but nothing as good as the ones made for root.
[Android Head-Units] surfer63:
You don't need root for that. Via adb you can access the unit as root user. You can make your /system read-writable and use the "block all ads via the hosts file". See here.

I have that also on my unit (and my linux laptop). Works great.

It is also part of my JET apk, but that one is not (yet?) ready for the new Intels.
