MTCD-MTCE PX5 Head Unit Audio Tuning Thread - MTCD Android Head Units General

I'm not an expert of car audio and i know the chinese head units are not the best (some people said "very poor" as real) in car audio but in this thread we can discuss the possible car audio quality improvements with the PX5, starting from the basic units to analyze the new ones with the new Analog Devices DSP (sold as optional) .
Personal experience in car audio tuning (with or without PX5 products) are very welcome!!
The standard PX5 units are equipped by ST's amplifier chips:
TDA 7388 (old PX5 units) 4x45W http://www.st.com/content/ccc/resou...df/jcr:content/translations/en.CD00179160.pdf
TDA 7851 4x48W MOSFET: http://www.st.com/content/ccc/resou...df/jcr:content/translations/en.CD00278574.pdf
The new PX5 units with Android 8 seems to be optionally powered by a DSP from Analog Device, the ADAU1701JSTZ chip (https://docs-emea.rs-online.com/webdocs/14b6/0900766b814b6bb7.pdf): i read the chip is possible to program with SigmaStudio software with related interface (http://www.analog.com/en/design-cen...opment-software/ss_sigst_02.html#dsp-overview).

This is my experience: i have an Audi A3 SPB TDI 2.0 year 2007 with Audi Bose Sound System (speakers+subwoofer+amplifier) .
In the past i had the old PX2 (RK3066 dual core) and sound was very bad in comparison with the original Audi Symphony radio (Blaupunkt) , ViperFX app not increased sound quality. Now I have the first model of PX5 (GS) with TDA 7388 chip, the audio result is better than PX2 of course but i was looking for best result in car audio quality...finally i had the right information from a very expert friend and i bought the Audison Prima AP 8.9 external DSP amplifier (http://www.audison.eu/products/ap8-9-bit/) . The AP8.9 was connected to speakers out of PX5 and to Bose amplifier. The quality of audio is totally improved and sound distribution in car is now perfect. Playing Pink Floyd's flac files is now fantastic for my ear, and the same wonderful result is from radio channels.

ministry of sound have had a bluetooth headset out for a couple of years now. i dont know its capabilities but i know it does work as hands free with the headunit doing all the muting ect. i'm guessing it could also do audio in theory but i'd be wanting hi quality stereo profile capable.

Nice find, but neither of those units support A2DP or AVRCP, and as you say, what we all really want is the high quality audio with the control functionality.

TaoTronics 2-In-1 Bluetooth 4.1 Transmitter / Receiver

TaoTronics Bluetooth 4.1 Transmitter / Receiver, 2-In-1 Wireless 3.5mm Audio Adapter (aptX Low Latency, Pair 2 At Once, For Home / Car Sound System)
This is by far the most useful product i have reviewed in a long time, If you’re like me and some older electronics such as a tv or stereo or even a car stereo without bluetooth then this TaoTronics Bluetooth 4.1 Transmitter / Receiver is a perfect product for you. If you know how to pair devices to bluetooth then you can add bluetooth capabilities to your electronics that were lacking this feature. Another feature i liked was you can enjoy a latency lower than 95% of other devices with aptX Low Latency technology; end-to-end lag time is now 40 milliseconds so high-definition video is transmitted without problems. I use this device on my older tv and a great feature of this TaoTronics 2-In-1 Bluetooth 4.1 Transmitter / Receiver is your able to pair Two Bluetooth headphones or speakers at once but please be aware aptX Low Latency does NOT support Dual Pair mode. The transmitter comes with a micro USB cable for charging, a 3.5 mm stereo jack for devices without bluetooth, and comes with a AUX stereo jack for older devices and you can use the device while its charging virtually removing any “down time”. You will be as impressed as I was with not only how easy this unit is to set up and use but most impressive is how many uses you get out of this unit, one of my favorite products I have used in a very long time.

How to working Rockford Fosgate System from Mitsubishi with Dasaita PX5 Unit.

Hello Guys,
iam new here and i need help.
since one Week i have a Dasaita HU with PX5, 4GB RAM, 32GB and it is bulid into my Mitsubishi Lancer with orignal Rockford Fosgate system.
And there is the Problem, how can work the Radio like the OEM Radio with the Rockford System? Maybe here other People with Mitsubishi and Rockford System and they using a Radio like mine?
Hope you can help me, it is a big Problem for me that it not work right
Thank you!
Robert
Is Nobody here with a Mitsubishi and Rockford and an Android Radio?

What is the Rockfors....an amplifier? a Subwoofer?
Did it have some RCA inputs?
Hey,
the Rockford Fosgate Systen is a complete OEM Soundsystem from Mitsubishi.
It Contains Speaker in all 4 Doors, in the Front Doors with Tweeters and in the Rear is a Subwoofer.
Did you buy your unit with Canbus decoder?
According to Dasaita, you need the canbus CB001 for models 2007-2013 and CB003 for models 2014-2017
The can bus is needed for Rockford Fosgate System to work with the headunit
You should buy harness with canbus
Ok,
but did you can change the punch of the subwoofer?
I am in a 2013 X and have a Dasaita PX3 unit. Subwoofer controls when you have the canbus box attached are not the sub bar in the Amplifier app but the far left 60hz bar.
Hope that helps.
It's like this one... But Dasaita may have it on their site Hot-Audio.

I have the same issue controlling the subwoofer on the PX6 with outlander and fosgate system. Controlling the sub with 60hz on the eq is hardly a fix as it is just lowering 60hz over all the channels . It would benefit to be able to adjust the sub volume as it seems to be louder than it should be. I am in contact with dasaita so will see what they say.

Hi
So I have a PX6 from navifly or whatever. Anyway had probs as well, went to a place called audiocity and now it works because(still cant control the sub punch but at least now it does punch) the wiring for the amp behind the radio was wrong. The amp gets its signal from the front speakers and behind the radio the driver side front speaker wiring was wrong. Its supposed to be both the same +/- but one speaker was the other way around and the signals were working against each other rather than working together. I think now you guys mby can try to find that. Now the punch was real gooooooood.
If needed I can do few pics or a video about this.
I cant control the sub that much but I can control the bass still. So it is punching good.
Hi, if it's not a strech for you I would really appreciate some details about this.
My problem is that balance does not work (if I put 100% on rear the volume goes to 0) and most annoying probleme is that I have a bass delay, which means that when the bass should kick in it actually fades in from 0 to whatever...and it takes like 5 seconds to be at the volume it's supposed to be. This i annoying because it does not only happen at the start of the song, but also on the entire track. From factory settings I chose the sound option without amplifier because the other two options (with amplifier and auto detect) don't care about amplifier settings after restart, so choosing a customized present (or rock, classical etc) does not make any sound changes. Any ideas?

Line-out audio quality on PX5 units

In the rare case that I can find a review on the sound quality of these devices, it's usually in regard to its amplifier. I'm using an external amplifier, so in my case it's actually the quality of the built-in DAC and its output stage that is relevant.
Are there any manufacturers of PX5 head units with a bigger-than-normal focus on audio quality?
I know that you can't expect miracles from these units, and car sound in general. But my speakers are fairly good (Rainbow Germanium, 3-way in the front, mid/bass drivers in the back), so I would like to try to squeeze as many details out of them as possible.
On the PX5 unit that I have, there are blank noise , all of this units have this isue. Maybe a unit whit DSP has a diferent sound.
One way of improving sound quality on px5 is to put DSP between the headunit and the amp.
There are other options discussed in mtcd threads.
If you are good with soldering you can add DSP to the motherboard.
I used Wadzio's mod and the improvement is noticeably better.
Read through mtcd software and hardware development boards. Then you can decide what is best way for you.

Sound issue with PX5 MTCE MX

Hello, I just installed a new PX5 MTCE MX V.3.32_1. I do not use an additional amplifier. Only use internal one. At first, no sound at all coming from the speakers. After having let my car shut down for one hour, I tested again. Now weak sound from rear speakers but still nothing from front one. Try to play with sound settings. Don't know what I'm doing. Don't seems that sound wants to come out front speakers. Before removing the unit and testing the wires, I would like to know if it has a setting to check.
PS.: My car is a Kia Forte 5 2016.
Tank you for your help.
In Factory Settings, there're 3 sections where you can play with attenuation: the section where you can define the volume level for each audio source (radio, main board, DVD if you have one), the section where the CanBus decoder is defined, and the general / other sections.
Also, make sure you are NOT using RCA connectors but the CANBUS connector. At least on my unit, the RCA outs are NOT amplified.
If all fails, you might have an issue with the amplifier chip. It is easy to replace if you have some soldering skills
Hope this helps
Max
I'm also curious on this problem.
I had a PX5, android 9, 4GB RAM. Right after installing to my Mercedes W203 car, it played well until one day. All the speakers have no sound.
I shut down the car for few hours, factory reset the head unit. After that, the sound come back at normal, except when playing FM radio. The sound for radio only come from right side speakers, no sound from left side speakers. Other apps play normal sound (music, maps, call...)
Please help if you guys have some experience on this problem.
