Sub Out on Xtrons PX5 - MTCD Hardware Development

Hey guys,
i've got a Xtrons PX5 Android 8.0 Unit (xtrons pb78aa3rp) and I don't have any subwoofer output in the harness.
Are there any mods to add this?
And does anybody know if this really has a DSP built in or should I give thsi addon board a try?
https://de.aliexpress.com/item/4000095694713.html?spm=a2g0x.12057483.0.0.1c5673a1t6a4hM

Is this a development question or a q&a forum question.
If you want to find out if the unit has a dsp, what options have been tried from the number of detailed posts outlining how to do so.

If your HU has DSP it should also have a 15 band equalizer and adjustments for distance to speakers or delay.
The unit you listed does not have DSP but it has a subwoofer line out. There is no sub output from the built-in amplifier.

Ok so it´s like I thought about the DSP.
But the problem with the subwoofer: although the spec says it, i had no line out for the subwoofer on the harness. only rca outputs for the 4 speakers or integrated in the OEM Quadlock.
So did I get the wrong wireing harness or is it not available on px5 units? without DSP?

Their listing shows connector 22 as part of the wires they supply with the HU and since that unit is not supposed to have a DSP then they should still have supplied the connector. If they won't send you one you could always open it and add a cable.

I got a reply from Xtrons:
Hi, pb78aa3rp has not an external subwoofer cable, it is built-in, you don't need a seprated subwoofer cable to get thr subwoofer work

and
hi, the harness is correct, the factory doesn't supply a harness with external subwoofer cable

So we all know this answer is not really satisfying. I think the sub out is still there on the board.
So if anyone has a PX5 with subout could ou tell me on which Pin of the connected is the sub out connected?

best in-ear BT stereo Headset?

has anyone tried in-ear headset with the tytn?
i'm looking for omehting like this, and i prefer it would have an adapter for any 3.5 non-BT devices (like my creative zen )
i'd appreciate any help
Well, my OMIZ BT set works quite well for that.
could u supply a link plz? i googled and ebayed it...nothing
You cant have looked very well, one search brought it up!

I use the S9 from Motorola. Somewhat expensive but the sound quality is amazing. Just make sure you put on the correct size ear buds (comes with 3 sizes) to get a good fit.

Seems like this one comes very highly recommended:

Seems like there is a 40sec pausing issue with 8525's (not the headset) that has been addressed with a patch from some of the smart folks on this website.
hmm, I don't know of any BT stereo in ear set with a detachable 3.5 jack other than the OMIZ.
This one, Motorola S9, have control buttons, call buttons, and that stuff, like the HT820 one?
The Sony Ericsson HBH-DS970 works marvellously for me

Speaker dock

Anybody find a decent speaker/dock system for the Gtab? Something like this:
http://the-gadgeteer.com/2010/11/15/jensen-jips-250i-ipad-speaker-dock/
We're not likely see anything like that for the g tablet unfortunately: there just isn't a large enough user base for mainstream accessory manufacturers to be interested.
Welcome to life on the fringes.
Funny, i was at Target thinking the same thing. I saw this same item and had hoped I could find some thing similar for the GTab.
I wish the basic dock had audio out. I was thinking about leaving the dock and a set of PC speakers here in my office. Not as elegant, but effective.
Get hdmi speakers.

I said the same thing a while back but found pricier speakers that used hdmi in the end.
Has anybody tried using some portable bluetooth speakers with the Gtab?
These look interesting. I'm not really looking for a booming system. Just want something I can take on vacation to enhance the stock, internal speakers.

look for a set of good quality PC speakers. Sound is great and they are fairly small.
Just ordered one of these:

Let us know how those Altec Lansings work. I'm curious about having a portable speaker system that I can take on trips as well.
Will do. In the meantime, here's the video that convinced me to give it a shot. The price isn't bad at all either - just $25 shipped.

Creative has a portable bluetooth speaker: D100
http://us.store.creative.com/Creative-D100-Portable-Bluetooth-Wireless-Speaker/M/B003N9SR00.htm
I have the Creative D200 and the Creative ZiiSound D5 which are both excellent.
I also use the Belkin stereo bluetooth dongle which works well:

That bluetooth dongle looks pretty sweet. Any complaints about the range on it?

[Q] Best way to stream music to older stereo receiver?

Have the Viewsonic G-Tab and finally got my music library loaded, and I am now looking to stream music from the tablet to my basic stereo receiver/speaker setup - currently the receiver doesn't have any wifi, bluetooth, etc capabilities. Just the old red wire/white wire connections.
Does anyone have a recommended accessory to stream music to it, via wireless, bluetooth or otherwise? I do have an Apple Airport Express, but it doesn't seem like that is a viable option.
Thanks!

it can be easily done ..
If you want to go wired, then just use the headphone output of your gtab to the stereo RCA input on your receiver.
Can be found at any dollar store or pick it up from ebay for $1 shipped

If you want to go wireless, you will need to use a BT adapter, connect it to the above cable (instead of directly using the gtab), then connect the gtab to it using bluetooth.
Here is one that is $20 shipped.
Hope that helps,
Best FM transmitter ever. I have had 2 of them in the last say 5 years. My original I gave to my parents when they got an android phone. But my wife got a new car with no aux port on it, so I picked up another one.

How do you expect the OP to use this at home ?!
Whoops, I just assumed it was for a car stereo.

Fiio e06 vs e07 vs e11...please share your experiences

Hi!
I was hoping to get feedback for those if anyone has tried them with the Ultra.
I find the ultra lacking in power and dynamics so...I ordered the e06 and will be here soon but then got thinking maybe the e11 was better or maybe even the dac/amp combo of e07.
Mainly I will be using a TDK IE800 and later a regular size headphone like maybe a Sony MDR-XB700 if I can find one for a good price or maybe I will go with with an AKG ...not sure yet.
Thanks for any comments!

Fiio E18. Takes the DAC out of the phone and into a offboard headphone amp.

I tested it last week at CES and it works well--with all audio tested (Youtube, Rdio, local via Walkman).
I got the E6 and E11 coming to test at home..just amps of course. If that does not make me happy then I will try the E18 but I do like the super compactness of the E6

Roger that. I've got the E06 and it does well. It certainly puts more power and bass. My favorite is the E07k because it also allows me to tone down the treble (if, for instance, I have my Audio Technicas connected--they're very bright), but bring up the bass (the open ATs need a little push).
Do you know if there is anyway to change the headphone out of the Ultra to like line out or something that is not double amplified basically..not sure if I am being clear

Does z ultra use TRRS band for its 3.5mm jack?

Hi all,
Was impressed by brainwavs delta iem.they say that it requires 3.5mm jack in TRRS band. Is z ultra compatible? Please provide your inputs.
Regards

TRRS means tip ring ring sleve and it refers to how the 3.5mm plug is configured.

Almost all modern phones with a 3.5mm port support this configuration. No need to worry about this.
The only major difference is how this technique is being used. Apple has their system and Android has their version.
When you buy a headset choose or tell the seller what device you will be using and the headset will work fine.
For a visual guide. Apple compatible headsets has three buttons on the headsets cable when Android compatible headsets has only one button on the cable.
This image below represents the Apple version of this product. You can see three buttons: Plus, Play/paus and Minus.

Some samsung phones can take headsets with + and - buttons.
Problem is there's no definitive standard for this.

But there is. And Apple will charge phone makers an arm and a leg to use it.

Many manufactures has designed models in a range of years when they used the ctia standard. Also Sony used it in some of their early Sony devices.
Each designing their own solution they followed no standard. And many now only uses the regular omtp.
I found an old cached website describing the details
http://webcache.googleusercontent.com/search?q=cache:jCfoZjj6TqsJinoutsguide.com/HeadsetsHeadphones/samsung_moment_pinout.shtml+&cd=1&hl=sv&ct=clnk&gl=se
The old HTC hero used a 600ohm resistor, a 220 ohm resistor. This was a time when inovation happened every day.
Further down it describes:
"To detect and use an external input, the Samsung Galaxy S needs to see about 1600 ohms impedance between the microphone and ground pins. This will automatically disable the internal mic in the phone. To connect the output from a PC or other audio device into the phones mic input, you'll need to add a 1.6k ohm resistor in series. This is the same procedure that works with an iPhone."
As we know there has been tons of lawsuites and patent disputes with Apple. Finding the right document is not what I have the time for.
I can not confirm if Apple is the patent holder of ctia. Or if it is free to use. Because many devices does use ctia standard today. Perhaps under license you can use the technology?
Or there is a legacy ctia standard that Samsung uses that can handle multiple buttons but does not upset Apple for looking to similar to their solution?
