I am wondering if there would be a possibility to get a audiosignal eg. linelevel via the 4p jack connector. As for splitting up the headphone output and the mic input and using the mic in with a shunt resistor to match line level for recording into one of the 4track Apps.
- Is there an acessory existing?
- If not, does anybody know the pinout of the jack plug and the impendance of the mic interface?
Anybody tried this jet?
I'd say it should be possible, as the headphones that came with my wildfire have a built in mic.
As a guess the tip and 3rd ring (both ends) of the jack would be the pins that should be used.
It works! Finally...
Last weekend i took same time to solder a solution. I managed to make a small box with a voltage divider (impendance changer) and the small 3P jack cable attached. I have now at the box a Potentiometer, headphone out and a more or less "gainable" mono Line in. I can now record 4 tracks of my Guitar into it. Using JZ2 its bit tricky due to the fact that no clicktrack works jet so i record one of the 3 Tracks with a Click and have 3 left. 2 for a mix and one for the recording and bouncing. Hope a metronome will be integrated in the app soon.
whats the quality of recoding like?
yes,whats the quality of recording like?

I didn't find here the pinout description of 2,5mm jack connector from XDA2.
There is stereo out, microphone in and two buttons.
I tried to buy 2,5mm connector, but it is not usable - connector itself fits to the XDA2, but the connector's body is too thick so the connector can not be fully plugged in.
So i bought some Nokia portable handsfree, which is also equipped with 2,5mm jack with four pins. So all i need is to know, how it should be connected.
I also bought a small plastic box, two 3,5mm stereo females and two little buttons. All of those things will be installed into that tiny box (plus the Nokia 2,5mm male connector). So this will work as an universal adaptor: from XDA2 to anything. I already bought big HiFi earphones with built-in microphone - it has two male 3,5mm jacks - one for stereosound, second for the microphone - so I'll be able to connect it to the XDA2 using my homemade tiny box and HiFi telephoning will become the reality ;-))
I'd also like to make a "homemade" simple car handsfree : I'll connect XDA's audio out to AudioIn on my car audio (also suitable for playing MP3 from XDA on car audio system). And I'll connect a standalone external microphone to XDA, microphone will be placed somewhere in the cabine.
Does it sound insane? Or realistic? Does anybody know the XDA2 jack pinout?
http://xda-developers.com/connectors/
this is xda1 but they are suppose to be able to use the same headphones
so it would help a bit
even though the xda1 dont support the 2 button thingy
Hey, as I trashed my cable I had to find out a little bit about the connecter
I write this from memory, so please handle with care ;-) :
from top to bottom
top ring - stereo out (left or right)
next ring - stereo out (right or left)
next - microphone in
next - ground
metallic ring in the inside of the connector - phone switch
By the way.. these pins are protect versus each other.. you'll have some tries..
Alex
The truth is that I can use the system connector instead of the 2,5mm jack.
AudioOut and MicrophoneIn pins are on the system connector as well...
So meybe I'll make SystemConnector-to-3,5mmJack adaptor ;-)
Or is there a difference?
Ehm..I had simply buyed a 2,5 to 3,5 Jack and cut a piece of it to fit into phone:

Well, OK. But it is only a stereo out, you don't have a microphone in. I'd like both of them plus those two buttons (red and green phone button)...

this one have the mic but dont support the pickup and slam down of the phone

well if you wanted to connect something else to the sysconnector you would not be able to connect something like charger or GPS
then imho it would make more sence using the 2.5 connection which cant be used for anything but sound anyway
Well, I am looking for such a device, but then one that will work with the XDA2/MDA2
Because I would like to use my own B&O headset, but would like to keep the phone function with microphone and answer buttons
So if somebody would like to spend an hour on the web for a detailed surch :wink:
make it your self...
takes less than 30 minutes (if you know how to use a solder iron)
I did it and I am trulty happy with it.
Alex
but is it not a problem that the lengh of the 3.5mm headset get added to the length of the wire from the device to the buttons and mic
i mean the mic need to be able to reach ones mough but the lenght from ones mouth to ones ears are not that long and with the added 3.5 mm headset lenght it would seme to become a wire mess?
Yes and No...
Yes if you do nothing.
No if you wrap it up a little.
well if you wrap the wire you will create a coil line effect
and that damage audio quality
just kidding i'm not a real audiophile
It seems that info in xda-developers.com/connectors/ is aplicable to XDA I.
XDAII headset has 2 buttons, answer and finish.
I'm specially interested in the 22pin pinout, that I've told IS DIFFERENT from the XDA I.
Can anybody point me with updated info on XDA II conneectors?
Thanks

Alex,
This is correct. The XDA II uses 5 pins instead of four. The switches are both connected to the 5th ring on the inside.
Until now, I wasn't able to find this connector.
Seems it's only used on the XDA II.
The diagram of the XDA I connector is correct, only the button isn't connected over the microphone to ground. So if you only need audio and mike, use that schematic.
Grtz,
Jos
Hola!
I'm trying to work out how to make my own XDA car kit cable. I have the pinout for the XDA - thanks to the XDA Developers Site
- http://wiki.xda-developers.com/wiki/Connectors
I also Have a pinout for the back of my Stereo (Philips CAR 400 From a Vauxhall Astra - '02) thanks to
- http://carradio.hit.bg/philips.htm
I have done some preliminary testing with small cables and connectors that go into a standard phono input on my big stereo in my room and have been successful at making a mini-kit, but am having real trouble working out what the pins on the back of the car stereo do (i.e which is for audio input from the phone)
Labels are as follows:
PHILIPS CAR400
01 - SVD
02 - SAC
03 - SCL
04 - Tel. Mute
05 - TIS
06 - Batt. +
07 - MRQ
08 - Power Antenna
09 - DDL
10 - Lights
11 - ACC ( 12 v + )
12 - GND
13 - SDA
The only one that make any sense is Tel. Mute (Anyone any idea what voltage I have to put accross this to get the system to mute)
If anyone knows what the rest of the pins stand for your help would be much appreciated.
Many thanks,
Will
You put the mute to earth to mute the stereo - normally it's floating.
1 down
Good good, one down, 12 to go.
Now I've read your question.
Answer is probably none of them. All the mute does is silence the audio (and pause the CD on some radios) - the assumption is either that you have a remote speaker for the phone or you use some commercial adapter like Autoleads to intercept the output to the car speakers via a relay. Autoleads sell a huge range of car/stereo specific leads that all provide a "generic" phone interface for Nokia phones. There are also a number of patch leads that enable you to plug specific car kits to the Nokia interface (which is just Battery, switched +, ground and mute with a 3.5mm jack for mono audio. Most knowledgeable guy for this stuff is Terry White on http://www.siocommunications.co.uk/ (he'll sell you the appropriate leads or make up what you need).
Note that the Autoleads solution (which mutes the stereo and uses relays to swich the audio from the phone to front speakers) renders the stereo automute unnecessary, but it is nice to pause the CD anyway and usually you get a front panel indication of phone call which is useful.
I note that the Philips connector also has an audio L/R/Gnd input. This is probably for an aux source like an MP3 player (eg XDA) but of course this needs to be selected on the radio and will also be muted when the mute pin goes to ground.
Hope that helps
I guess the other pins are things like CANBus, D2B wakeup etc. a bit like Siemens/Bosch
Last one. The Autolead you need is 06-078B - £47 + pp from Terry.
http://www.siocommunications.co.uk/06-078B.html
Phew!
That's a mighty big cable?
I notice that it has a 'big connector' (I've marked it in yellow on the image I've attached with this post). There is already one of these on the existing setup. This wouldn't mean I have to completely rip out all of the existing wiring would it?
Also, the jack (Red on the image) looks like a mono jack, I assume this is the bit that plugs into the phone or which I can adapt to plug into the phone?
Seems a bit expensive too, is it really necessary? Can I just forget the auto mute feature and have the phone output go through the 'MP3 In' inputs? That way I can listen to the music on the XDA through the car stereo as well as any sat-nav stuff I decide to install later on.
The main aim of my question is to try to develop a cheap solution to an XDA-Car audio interface. Do none of the connections on the back of my stereo allow me to wire in some sort of auxiliary input?
Yes it is big but it does the job and you can usually find room.
The connector(s) go in line with the ISO and stereo specific plugs, so routing all the power and speaker outputs via the relay module. You don't rip anything out, or need to break into existing wiring, so you reduce risk of problems or warranty issues - it really is the lowest hassle solution.
Yes the red plug is the phone audio input and is designed for Nokia kits.
Expensive? Not really, considering you avoid any hassles and can remove the kit after with no changes or damage to the car wiring. Replacing connectors and fixing car wiring can be expensive.
Yes you could go into the Philips cnnector from the XDA, but you would have to manually select Aux in on the radio, and it wouldn't mute anything. If you were listening to the car radio you'd need to answer the phone and also switch to aux in on the radio to hear anything. Sounds a mess to me!
OK
Ok, so assuming I use the new connector to wire in the phone and have it working through a seperate speaker, how do I connect the MP3 Outputs of the XDA into the stereo. I have no problem using a seperate speaker for the voice on the XDA but I really want to play the XDA music through the Car's built in speakers.
I understand I'll have to come up with some way of getting the sound from the XDA to the speaker AND the car stereo but I don't mind that, It's just something I'll have to worry about.
Most car stereos I've seen have a seperate set of Phono Sockets for auxiliary inputs but this philips doesn't. What do the pins on the back actually stand for in english? (Laymans terms please because I don't understand the long names but I will be able to fathom how to use them if you tell me what they actually do, long names might be ok too cos I can always look on Google to find out what the various bits do.)
Actually I screwed up - looking again at that wierd Bulgarian* site the CAR 400 looks like it has the 26 pin connector and the phone lead would be Autolead 06-053B.
http://www.siocommunications.co.uk/06-053B.html
Also it looks as though the CAR400 does NOT support Aux in - sorry about that - although you could try putting signals onto pins 9 and 10 (using 3 as Ground) and see what happens (that's what the CAR660 uses). No warranty actual or implied!!
* This guy is promoting software to crack EEPROM codes on car radios and to clock cars with digital instrument clusters. Not sure I'd be so keen to build a close relationship there mate!!
No Fear
Thanks anyway, I've got a few exams to sit this coming week so no chance to fiddle for a bit but I'll post back again once I work out how it goes. Looks like I'll have to find some sort of seperate amp and patch it in somewhere to output to the car speakers.
No connection between me and the Bulgarian bloke, just found the site on google as a means of showing you the pinout on the back of the CAR 400.
I'm assuming Pins 9 and 10 CDR and CDL stand for CD - Left and CD - Right respectively?
One last quickie before I go, can I source ISO connectors (Just the plastic bits) from anywhere so I can maybe make a patch through cable? I'd need a male and a female one.
i.e.
CAR STEREO (FEMALE ISO) ---> Wiring (MALE ISO)
becomes
CAR STEREO (FEMALE ISO) ---> NEW MALE ISO --------> MY STUFF ---------> NEW FEMALE ISO ---> Wiring (MALE ISO)
Cheers for the help, I'll have a mess about over the next few weeks and post back with my results in case anyone's interested.
Just a note to say I've found some ISO Connectors. You can get them from maplin.
http://www.maplin.co.uk
codes
QK25C (headunit end) @ £4.99
MZ76H (car end) @ £6.99
Anyone finds them a bit cheaper let me know...
Another quick note. I've found a small amplifier from Maplin (Code N67AW) 40W 6-16V. (MONO ONLY)
The instructions say it is a 'bridge type' amplifier and that the speaker connections should therefore not be to ground (As in a car).
The setup works fine on my test rig at home, but I was wondering, will I just get lots of noise if I connect it up in the car, or will I blow everything up?
So far my plan is to make a patch through cable that amplifies the XDA signal direct to the car speakers and has some form of automatic switch to detect if audio is coming through the XDA. If it is, then it mutes the signal from the car stereo and patches the XDA through.
Any suggetsions?
Hi,
I want to connect an external speaker and microphone to my Qtek9090. I thought the easiest way to do it is to simply cut the headset wire, plug the 2.5mm connector in and connect my speaker and mic to those wires. I have taken apart the headset that comes with it and there's the following wires in it:
wire1:
- blue
- copper(1)
- red
- red/green
wire2:
- white
- copper(2)
From taking apart the volume slider I think blue and copper(1) are the wires for the audio (L&R). But I'm not sure. I can't figure out what the mic and ground wires are :?
Does anyone know more? Anyone tried looking at this?
Grtz,
DUTCH
just feed a low level audio signal to the wires. You should distinguish left and right. The remaining one must be the mic....
or...
buy an adapter. Both expansys and proporta.com sell adapters.
Nigel
I've been searching for those adapters and found many. The only problem is: none of them have a microphone connector :? .
Now I might have an option here, but i'm not sure this one suits the Qtek9090 (Blue Angel) I have: if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.
The only thing is: what part of the headset connector is the microphone? The tip?
Grtz,
DUTCH
Blue Angle Plug
Tip Mic +
Band 1 Audio Right +
Band 2 Audio Left +
Base Common Earth (-)
Headset Lead

NOTE
This is not the same as it was on the Himalaya.
Therefore no adapter or headset made for the Himalaya will work with the Blue Angle.
Do you know if it's compatible with nokia headset ?

No, I've tried with a Nokia wired headset and it didn't work at all.
I ordered the audio connector mentioned (this one).
When recording a note for example everything works just fine, BUT when in 'phone mode' (making a phone call) it doesn't work.
Anyone got a clue/solution for this? Or should I start thinking about making this work via the 22-pin connector?
Grtz,
DUTCH
9090 should support audio from the bottom connector. I assume you want to use it in your car. If you want to connect a external speaker you should amplify the signal. There is a DIY carkit on http://wiki.xda-developers.com/wiki/Connectors . Maybe this could be handy. Also my phone supplier told me that in about a week there will be a complete carkit WITH decent Carcomm cradle and GPS connection (all wired so no BT connections needed). I will buy this when it is released so will keep you guys updated.
if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.

I purchased this one for my old TMobile xda I and the Blue Angel.
Both are headphone jacks and niether cna be used for a mic. There is a built in mic and mute button (that you have to hold)

Hi,
Since the ExtUSB connector is mono (or at least that is what I have figured out from the schema) I am looking for a bluetooth or wired device that will have a mic (3.5mm) connector. I would like to record with my TyTN II.
Any of those out there?, I have been searching for hours with no luck.
I want to use my Sony ECM-DS70P stereo mic (no amplifier) to record.
I would be perfect if the same gizmo would have a 3.5mm out connection for headphones.
The thought is to stream audio data out to a server for live stereo sound (live music, open spaces, etc). Mono could do, but the difference is enormous on the mono mics I have tried, the sound space is lost.
Another solution would be to get an mp3 player with bluetooth such as the TEAC MP-500BT, but I don't know if they will work together and if the TEAC has an amplifier for the line-in. And why have 2 devices anyways?
Thanks,

this is the closest i've seen
guess you could go DIY but i suppose you had to deamp the signal to avoid it to overstear the mic in the pda
I thought about opening up one of these and soldering a 3.5mm connector on the mic wires but then I found out that the ExtUSB connector is mono. That is why I thought that there may be easier to go bluetooth.
- j
yeah all mics in all pda's are mono it really make no sense to do stereo with only 1 mic
you can just use one of the lines and ground to connect a mic
if there is a bluetooth device which meets your requirements i've never seen it
nor do i believe the market is big as recording 1 audio source in stereo dont make sense stereo is for more then 1 audio source
so if there is a bt device i'd say it's a nitche product which will likely cost
Makes sense. The difference between Sony ECM-DS70, which is a low budget (EUR 50) mic, and recording mono with pricier mics is huge, the detail is better on the mono mics I tried, but I get no sense of space which is what I am aiming at. Thus I need to get the sound into the tytn somehow.
Hello guys,
I tested apple earpods on my HTC DHD. For the music portion, they sound pretty good, the control buttons works fine but thats no good if i cant even take a call. The microphone does not work and the person on the other end of a call hears a high pitched whine.
Is it possible to use the phone's microphone when the earpods is plugged in?

One can get a 3.5mm 4 poles audio stereo male to female extension cable then cut the cable in the half and interchange the Ground / MIC wire connections with soldering iron.
