[MTCD Hardware Development] Pacote-san:
Since Im using an external amplifier Im sure I can use RR and RL to go to the sub channels (2 channels in bridge to give me 400w rms) But Im unsure if I would be able to controle the sub with the slider.

I ordered the dsp chip and the board to use as sub out if needed.

I wont be needing the analog switching cause I will only use fm radio. I dont use AUX for anything.

MTCE

[/COLOR]Anyone done it on unit similar to this one on the pictures?

This is PX5 Eonon unit with MTCE base

It is using BD37033FV chip. Looks like the pinout is the same as on the other boards. Two rows of headers around the chip are useful for connections but I'm not sure about the pinout.

Some other question... there is a DVD in my unit.. (which I dont need). Will there be anny issues if I will leave it out?

[IMG="Board layout"]https://i.imgur.com/aqQDzCT.jpg[/IMG]

This is my guess at the pinout:
[MTCD Hardware Development] pir8man:
Patcher2k posted a PCB layout to connect directly to the two rows of headers that your unit has.

If I had your model, I would order a PCB from his designs and install the mod that way.
[MTCD Hardware Development] Nicez:
Hi guys, just stumbled across this thread I have some questions.

I've ordered and installed a PX30 HU obviously without dedicated DSP and the sound was horrible.

I wasn't really informed at this time so I sent it back for a refund. Now I am looking to get a android HU which meets my audiophile requirements.

I only use the RCA outputs in my setup which are connected to three amps. They fire my front and rear system as well as a subwoofer.

With the previous HU the sound was not very clear at higher levels and the bass lost all its precision, like I said it sounded terrible overall in comparison to my previous DIN1 radio (Kenwood KDC73 DAB).

Can you tell me if a HU with dedicated DSP (ADAU1701) will improve the sound significantly in my setup in terms of precision and overall quality?

I found this one which would fit in my car: Erisin ES1889b

https://www.ebay.de/itm/233465442847

It shows the 15 band equalizer in the pictures. Is this a proof that it comes with the DSP or could it be fake.

Thank you in advance
[MTCD Hardware Development] pir8man:
yes, a HU with DSP will give good sound quality after configuration.

The unit you found does have the hardware DSP. Erisin units have a fairly weak CPU.

A similar unit with PX6: HERE (just be sure to select one of the PX6 sub-models)

An all touch-screen 9" unit with PX6: HERE
[MTCD Hardware Development] Nicez:
Thanks for your response. I think I will give it a try with the Erisin PX30. I don't want to order from Aliexpress since I don't know if I will like the sound quality and keep the HU. I prefer ordering from local Ebay or Amazon to have the possibility of sending back the HU for a refund or in case of any failures on the system.
[MTCD Hardware Development] pir8man:
I have no problem making returns on AliExpress. Although, feel free to keep to what you are comfortable with :)
[MTCD Hardware Development] Snipeg:
Just mounted DSP module to my PX5 unit. It is just awesome! Sound is excellent. Now I just have to make it nicer and add input selector for analogue channels. Now I have only blue-tooth connected to that one analogue input on DSP board
[MTCD Hardware Development] Pacote-san:
My board arrived and Im just waiting for the other board (for sub) to arrive so I can start soldering :)

---------- Post added at 02:37 PM ---------- Previous post was at 01:56 PM ----------

I think I asked before but didnt get a proper answer.

Anyone know If I can just use the RR and FR directoly to my external amplifier?

The stock SUB OUT rca would work normally? The sub slider would work or I need to solder the other board in order to control that?
[MTCD Hardware Development] Pacote-san:
Can you help me out with this mod? I have a few questions and Im unable to find those here.

Can I solder this mod in a way that I can use all the stock rca connectors? FR, FL and SUB out?

---------- Post added at 03:15 AM ---------- Previous post was at 02:35 AM ----------

In the first post is says

But in your installation and this diagram

FM R and L are on pins 8 and 9 so what gives?
[MTCD Hardware Development] Pacote-san:
And one last thing, just to see If Im correct on what I need to do.

I want to use the SUB OUT RCA that already comes out from my HU so, I will be using this:

https://i.imgur.com/xcyjS0i.png

So if Im correct reading the first post:

SDIN -> solders to S_DATA from DSP chip (MP6)

SCLK -> solders to SCLK from DSP chip (MP11)

LRCLK - > solders to LRCLK from DSP chip (MP10)

MCLK -> solders to MCLK that comes from PX5 chip

GND -> Any ground

VDD -> where do I get the 3.3V ?

And then I should get either the left or audio output from the P2 socket and solder to where was pin 19 on the BD37033FV (sub out) correct?

https://i.imgur.com/Wt14C0x.png

Then I can just use the SUB OUT RCA that I already use to connect to my external amplifier and will be able to adjust the sub values on the app right?
[MTCD Hardware Development] Pacote-san:
I followed sda2 picture on how to get the signals from PX5 that doesnt have the extra 4 pads and this is what I got

Soldered like the diagrams

When I boot with stock MCU I still get the old AMP (not the new 15 bands one) and only noise on my speakers

When I turn the volume down or Up I get a feedback (the noise changes)

What could be wrong?

FIXED:

It was late at night I misread the ground point and that was the issue.

Soldered the correct ground and its working perfectly :)

Now to solder the other board for the subwoofer :)
[MTCD Hardware Development] Pacote-san:
I did like my post above and while I get the subwoofer working, there sub on/off or adjusting gains does nothing.

So theres probably something wrong, hope someone can help me out :)
[MTCD Hardware Development] Pacote-san:
Welp , I give up for now on the external sub working... I wired up the same as all the diagrams I saw but the sub button on the amp app does nothing, the sub is just on all the time and you cant change anything.

Also I cant use bluetooth a2dp or for calls. When I wire the pins 10 and 11 to DSP , FM radio works fine but whenever I try to call someone or open BT a2DP all I ger is FM radio sound.
[MTCD Hardware Development] Pacote-san:
Im not sure if its something with Hal9k Rom, or my BT module (probably it) being SD-968 but the audio is not being sent digitally from android to DSP.

If I take the FML and FMR out of the DSP I get no bluetooth sound

If I wire it, I get FM radio where it was supposed to be bluetooth sound.

Will probably take it off everything and solder the old chip back because this is turning to be a huge hassle trying to find out when there were so many people who did this mod so, there a lack of support =/

Xtrons PQ PX6 DSP Upgrade?

Hi there,

did someone happen to retrofit a DSP module on the PX6 xtrons?

I found a special module from aliexpress: " XTRONS DSP Chip Modul Nur für XTRONS Android PA 8,1 & PA 9,0/PB 8,0 mit "ICH" & PB 9,0/PBX/PQ Serie "

Sorry, I'm using the Google Translator.

Best wishes.
[MTCD Hardware Development] patcher2k:
Hi,

you should read my post #72 and maybe all the others in this thread. Then you find the answer to your issue. The "normal" eq chip has more analog inputs with an internal multiplexer. The dsp needs an external mux controlled by two gpios.
[MTCD Hardware Development] Pacote-san:
I pretty much read all the post at least 3 times at the time already.

It was my understanding that bluetooth was using digital audio via android so it wouldnt need another via for it but I was wrong of course.

But I already soldered the old chip back and gave up since I wasnt able to do the sub working properly.
[MTCD Hardware Development] ELCouz:
For those who did the DSP upgrade did that solve the background noise issue?
[MTCD Hardware Development] AddixNL:
Does somebody know where i can get those DSP daughter boards? So its like a drop in place installation in px5 headunit.

In my Headunit there is no DSP, but it has the serial connection on the mainboard for one to install (32pin). I would love to add one in and have some subwoofer filter control etc.

My headunit also has software dsp installed but gives me a error message ofcourse "no hardware dsp found on serial port blabla" .

So i think when u add a dsp board it should see it and must be working.
[MTCD Hardware Development] marchnz:
I doubt it. Internal noise enters the audio path.

I have STM32F.
[MTCD Hardware Development] typos1:
Interesting, does you SoM look like that [MENTION=7551580]Docsnow[/MENTION] ? Cos the STM32 units look like copies of MTCE units, they use the same MCU chip - the apps are very very similar, so it would be funny that theyve even tried to copy the SoM, as well.
[MTCD Hardware Development] Docsnow:
Ok im done. I buy a DSP Upgrade Modul. And that works for me.

The issue with the Background noise have i too. :-/ When anybody has a Solution, give comment Please!

Does anybody in Germany need a DSP Board, i have one?Write me
[MTCD Hardware Development] marchnz:
Noise is a design defect that could only be resolved through hardware modification, if at all.
[MTCD Hardware Development] Docsnow:
Not only noise but also Processorsignals as well as my alternator.

I heard the Noise also when Sound is Mute.

For Informationen, the FrontSpeaker are connected over Chinch an Amplifier.

Is think the Chinch Line is full of disturbances.

Note: I test on my TV the HDMI Signal. The Signal is Clear?

Xtrons D710P

Im thinking of buying an Xtrons D710P 1DIN unit for my old Audi but I just received notes from techsupport that this model doesnt have a DSP nor would they custom add one so I'm curios if it would be possible to add a custom DSP into it and make it actually work.

I've met a few sellers on aliexpress who custom add a DSP unit if ordered unfortunatley noone sells 1DIN motoryzed flip-out units with an A35 CPU. And dont want to go with an A53 cause I know those are a bit older.

P.S. I dont care about loosing warranty if that makes my unit sound that much better.
[MTCD Hardware Development] artemkopan:
I added BLM21PG221SN1 to 5+ line and it reduced noise
[MTCD Hardware Development] andre.berenguel:
What does it mean speaker distance (horizontal and vertical)?

Is vertical distance the distance between front and back speakers?

Is horizontal distance the distance between right and left speakers?
[MTCD Hardware Development] Silver_:
I think that is like you say, but Im not sure too.

---------- Post added at 11:47 PM ---------- Previous post was at 11:33 PM ----------

I had installed the mod for the MCU of sound ( https://xdaforums.com/android-auto/...ent/mod-cs-x-mod-mtcd-e-mcu-firmware-t3816042 ) that the truth from the first moment I noticed that the audio of my Headunit gained great quality . As I am dedicated to electronics, I decided to install the test board with the DSP chip. I put everything perfectly protected from noise and with shielded cables, I have no noise problems. When I did the first sound check I didn't really notice much improvement over the MCU´s mod, so after so much soldering I was a bit disappointed in the work that I had done. Does it have anything to do with the MCU currently having with this software mod?

Another thing that I also noticed is that I lost volume in some Android app like Voice Asistance of Google (Someone have this problem??) and, of course, the functionality of the DVD, as commented in previous post to this, but the truth is that I use it less and less.

Thanks I hope your comments about this.

I also assume, there wouldn't be a Q&A section dedicated to sharing oeminfo/custom.bin files with others in the thread I linked above, if it was not safe.

Hello,

I have a pixel XL updated to the android beta, and I wanted to donwload the Google news app. This app is not available in my country so I went to a repository and downloaded an APK. I installed it, and everything works as usual, the app is running smoothly, but when I close it and leave the phone idle for a few minutes the APP dissapears from the launcher. If I try to install it again the phone tells me that is already installed and I can update it, if I do that the app appears again on the launcher and I can use it again.

Can anyone help me with this? should I block permissions for Google Play services (I think that is what is messing with my apps)? or it is possible to install something to prevent this? maybe a modded apk?
