Hello People,
Is it safe to connect the BA to an audio amplifier/receiver using a modified addapter through the headphone jack?
I have tried it for a short time and everything sounded perfect.

Sure, just make sure you don't overdrive the input of your stereo system by setting the BA volume too high. You'll know you're overdriving it when you start to hear distortion. On the other hand, don't set it very low because then you'll have to crank up the volume of your system and you'll be amplifying a lot of noise as well.
Also, make sure you're using an input that is designed for a pre-amped signal, like a tape playback, AUX, CD or MiniDisc input. DON'T use a phono input as that is designed for low levels.

Thank You very much, Paul. I am using your recommended settings already with tcpmp as the main player and wifi connection to my PC, which is in another room.
All I need now is TV out from BA and I can say I have the all-in-one gadget a man can need. Thanks again.

i would also love tv out , is it possible??

Real STEREO OUT via mini jack?

hello everyone!
i was wondering, if the blue angel is outputting a real stereo signal via the mini jack or if it is just a mono signal on both headphone spekaers.... i once read something like this, cant remember where, cant say if its true...
does anyone know?
btw: whats that strange connection around the minijack for?
thx in advance!
krz
BA has stereo sound output for sure! I have made my own 2.5 jack to 3.5 jack wire, so then I connect headphones from player I can hear for sure that sound is stereo Don't try to create This wire by your own, better ask me, and I'll post photos how it could be done. Anyone is interested in creating wire?
PS: You can modify 2 ears-headset, from mono to stereo by shortcutting the diode (black* little square inside headset plastic box). Disadvantage: headset can't be used for calling anymore.
hi fatalistic!
thx for your answer! and yes, i would be very interessted in creating a such a wire... it would be graet, if you could post pictures and explanations on that topic!
thx again,

Hi
There is A patch for the PDA2k enz ,that you get the A2DP profile for the widdcom 1.1 bluetooth stalk then you can use the bluewalker or logitech (stereo)headsets.
suc6/good luck
thx for the patches!
anyone can confirm, taht they work on a ba?

hi guys!
i just received an answer of the HTC Technical Support to my quetion regarding real stereo via mini jack.... unfortuneatly, they pointed out, that the HTC Blue Angel DOES NOT output a real stereo signal, just mono on both channels....
what a pitty!
Well, with the 2.5 to 3.5 adapter I'm now using it most definitely does have stereo. On my hypnotherapy tape Paul Mckenna verbally identifies the left and the right ear, so I used that to check, and I don't think I'm tripping.
Not that I wish to contradict 'The Guy'.
adaptors are on ebay for 2.5mm to 3.5mm for about £1.50
Sennheiser Mm10
i bought an adapter from hama (2,5mm to 3,5mm), but it is still not working... i only get a mono signal in one earplug... sucks big time!!
anyone knows, if the SENNHEISER MM10 would work with the MDA 3 ???

Srz, dude.... but this is bull****, I certainly get stereo sound with the earplugs that came with my O2 XDA IIs.
The sound is stereo for sure. I cannot recall any Pocket PC without stereo sound output. At Tech support they don't know what they are talking about.
Try looking for old Motorola earphones (i.e. for MPx200) it has the same connector scheme. The usual 2.5 mm to 3.5 mm adaptor won't work, use the Motorolas one. BTW: Scheme is in wiki's general section.

Hi, I saw your post and i`m very interested in changing 2.5 to 3.5 stereo jack.
i use one kinda like this one
http://www.expansys.com/p.aspx?i=104589
the one i'm using is not made by gamin but nor is it spc for htc devices
just any old 2.5mm to 3.5mm converter
do u want to fix ur converter
hi guys
i hv spv m2000 giving 100% stereo sound. Recently i bought a 2.5 to 3.5 converter from ebay which was not compatiable with BA so i open it fix it. now its working perfectly.SO if ny bdy want to fix his converter tell me.
there are other way....
i have modified the original earphone (cutting and soldering) however, if you don't want those nasty work, just simply buy the original motorola e398 rokr earphone, good quality sound..
@ krishan2207 & evoluzionne:
thx for your answers!
do you think, you could describe how you fixed/modyfied your adapter/earphone?
maybe you have pictures? or some kind of tutorial?
this would help lots of people, i guess.....
@ evoluzionne:
are you refering to THIS headset? do you know, if the SEND/END button is working?
thx again!
krz
yes... (the send and receive button works) that's one.. good quality sound both bass and treble, vocal clarity, however it doesnt have volume dial, you should set the volume from your music player applications..
about the modifying of the headset you could just find it in the link below..
http://wiki.xda-developers.com/index.php?pagename=handsfreethatdoesntsoundlikecrap
of you just dont sure to do this just simply buy the motorola's e398 handsfree.. for its sound quality..
regards
adri
so? anyone try the motorola's?
have u guys try it? it is good and working isn'it? later, i'll show my modified handsfree, for some people it looks sucks but working perfectly....

[Q] 3.5" Headphones

Hi.
This is my first Samsung so, have mercy
None of my headphones are working.
I only get sound in one side and the other is too low. Almost inexistent.
I tried with cable to connect it to my audio system and the same.
Next step was to use the hands free from my X10.
Is working ... but not as expected. Almost no bass and no trebles.
The only ones working are the ones from the SGS2 box or using my headphones via MW600 bluetooth (which i don't like it as it drains more batter and the SGS2 is power hungry)
So, is a problem with the 3.5" ?
Or my headphones?
Or ... is a compatibility problem? Can i find somewhere an 3.5" adapter?
Thanks
Its gonna sound dumb but u have plugged the jack all the way in yeah? Takes a little bit more force than u think

Worked with other headsets for me
- Dell streak headset
-Iphone headset
Needed that extra push to fit the pin in really well
Well, i'll try one more time ... anyway, earlier i found something else using the X10 headset.
If i press the "answer" button from headset, everything is fine but as soon as is de-pressed ... it goes back.
I have a similar problem with my expensive Shure earphones. They sound much worst and "tinny" then the standard earphones that come with the S2. Even if these earphones are cheap, at least the sound is acceptable.
If I plug the output of the S2 into my car stereo, I again have terrible sound. I am not sure if this has anything to do with the fact that the stock S2 earphones have 4 contacts on the jackplug as compared to 3 on normal jackplugs. The extra contact, I presume, is to permit the switch for fast forward to work on the headphones.
I can't understand why other people don't have this problem - and yes the jack plug is pushed right in.
Yep, pretty sure, the jack is down entirely and still not working.
I tried with the SE X10 headset and normal stereo headphones
I think i will have to stick with the bluetooth if i can't find an adapter of some sorts.

[Q]CarDock Volume to high via Headphone Jack

So i finally got my cardock and set it up but sadly when i use the usb headphone jack to get the audio the volume seems to be at the max and it distorts badly on my car audio system.
i tried to turn the media volume down but there seem to be two settings: OFF and MAXIMUM
really weird.
im on the 672.180.33 Retail.en.EU ICS release.
any ideas?

BIG PROBLEM...terrible Noise USB Docking audio/charging out

Has anyone noticed terrible noise when using an S3 docking system or cable to output both Audio and Charging?
- extreme hiss and random noise, machine processor noise, crackle etc. (only if charger is plugged in as well)
- after 2 seconds of no sound, you can hear what resembles to be an AUDIO gate...that kicks in and mutes the noise until you trigger your next button sound.
- Even if you listen to a song, and think it doesn't happen while listening to a song...IT'S still there...fighting the song and causing degradation in Audio quality.
- not too mention, phone calls will NOT route through the USB jack, and music and navigation type stuff.
- if you unplug the charger, the sound cleans right up and sounds fine. It's the combination of having the audio and charging outputs all in one.
- ground loop isolators do not help
I have a background as an audio technician and some electronics skills and I did hours of testing and modding...unfortunately! All failed. I own an Ibolt car cradle (which I did most of my testing with), a KiDiGi desktop docking cradle, and I even hand made a cable that could trigger docking mode. All three of these scenarios FAILED with the NOISE factor.
I have resigned to thinking it is a hardware design bug with the S3. I have modified my Ibolt so that it sends out audio from an extra cable that plugs into the Headphone Jack...which as a bonus, as sends Dialer audio.
(I just realized that this is the i9300 thread, and I have a i747m but maybe this thread could help all the same)
I've had three S3's and used USB audio out to my car stereo via 3.5mm. None ever generated any additional noise.

Eddie...can you confirm these points:
1) You have a usb cable or dock that comes out the bottom of your S3, and it splits into USB for charging....and 3.5mm for audio? (NOT THE HEADPHONE OUT)
Is it a cable or dock and would you mind tell me the name of it?
2) What do you plug the audio into?
- stock car audio input
- front aux input on a car deck stereo system (stock/aftermarket)
- rear aux inputs to aftermarket stereo
- other?
3) with the steareo turned up fairly loud, but no music playing, do you hear any noise when you click buttons (assuming you have audio enabled for button clicks in Android settings) When pausing between loud music, do you hear any white noise, machine noise, hiss etc.?
4) What is your S3 model? (i9300?) and what OS version.

I've used the Samsung Infuse and also iBolt docks. Both have the split USB cable for charging & 3.mm audio.

I don't remember any noise when clicking buttons?
But we're talking about AUX input which is analog, so when you turn the volume up with no music playing, you'll always hear some "soft" occasional clicks & hiss.

AT&T GS3 with various ICS ROM's. I don't use AUX anymore because my favorite ROM (AOKP) doesn't have audio out capability when docked.

Thanks for replying Eddie. I am so sick of this troubleshooting this crap sometimes. I am very happy with the S3. It is a giant leap forward from my HD2...in most ways...but not all. I am suspecting the USB audio out on my S3 has a defect.
Right now, in the car, I have resigned to using the USB for power and the Headphone jack for audio send to the AUX input of my Sony car stereo on a custom wired Ibolt docking cradle. I still get some PROCESSOR noise when pressing the buttons but it is about 5% of the intensity of using the stock wired Ibolt, or KiDiGi desktop dock...or my hand wired Ycable. Without the USB charging wired up, there is NO NOISE whatsoever with either method.
Digital Output
Reading many threads last night, I discovered that with some roms/kernels, it is also possible to output pure DIGITAL audio from the S3 USB port into a select number of little affordable boutique like amps which decode and amplify the audio and power spkrs and headphones.
My first S3 had some weird noise when using bluetooth. So I drove over to my local corporate AT&T store and let them know. They walked out to my car with a demo S3 and we tested it and it didn't have any noise at all. So they swapped out my phone for a new one and I've been happy ever since.
Maybe you could try that?
Regarding boutique amps... this guy in one of my threads was talking about that. I didn't understand half of what he said.

Yup that's it. There are a few examples on youtube. Interesting how it's this TRADE SECRET feature. I mean, I have not seen this advertised anywhere and the places on the net where I found examples....the guys talk about it as if it's this common well known feature. Apparently, next to having one of these setups, the Iphone4 has the the best rating for sound/volume/curve output...almost neck to neck with a dedicated DAC...I think they call it!
I bet if I spent another $100+ bucks for one of these amps, and ran it in my car through a power Inverter (12v to 110v inverter), that I could run the Digital signal out without the interference of my USB analogue out issue. But, I am past that now.
Thanks for your input Eddie!
DAC direct solved this problem for me with Siyah Kernel.
This also happens when you are charged with a car charger and using the line out.

Arkanius...are you saying...
1) You had the same terrible noise when charging in a car.... with usb audio analogue into aux input of car stereo?
2) and that you hooked up a DAC to resolve the car noise issue? If yes, would you mind sharing the DAC model with us and the cable used?
Although I may be digging up an old thread, it may be worth looking into (Currently majoring in Electrical Engineering and having completed two signal analysis classes).
themadproducer, were you able to get a spectrum output of the noise? If it just a set of static frequencies, a cascading array of notch filters may work out
EDIT: reading your mention of the USB charging, its quite possible that if the voltage converter is of cheap quality, the transistors involved in the voltage conversion from 12.0-14.0 Volts DC down to ~5.0 Volts DC may be giving off Radio Frequency noise, with the noise being picked by the audio cable due to physical proximity, akin to cross-talking in network cables ( a form of mutual inductance)

Portable Audio Amplifier

Has anyone use the TF201 on an airplane with closed, but not noise-cancelling headphones?
I've found that it's not possible to get the volume up loud enough on my Audio Technica ATH-M50 headphones to be able to hear dialog in movies. The headphones are great, but even with a closed design they are just too quiet at the loudest volume to really hear well on an airplane.
Has anyone used a portable amp with the prime that you would recommend? I've done a quick search and it seems like a lot of amps need a digital input. I'd imagine that I'd just need a simpler analog amp that takes a 3.5mm input. I'm looking for something cheap to just help on an airplane. Any recommendations? The cheaper the better.
Check out of the fiio e line. They have some portable amps that use the 3.5mm connection. I have a fiio e6 and i like it

Have you used it on an airplane and does it seem to give you enough of a boost to overcome the background noise? I think I got confused when I saw the fiio amps because they photos show them hooked up with a custom connection to an iPhone for example, but now I see they just take a 3.5mm input.
And they aren't too expensive so I might just try it out.
I have the same model headphones.. a Prime.. a Fiio amp. The cheapest one... And they work great! Makes them much louder

using windows phone 7 on my hd2 you could increase these volumes from the rom. Is there nothing like this in android?
Don't know if you tried any of the apps on the play store. I use volume + app. Works great. Lets you go above the stock volume levels for both the internal speakers and headphones. There are other apps out there to boost volume as well.

Of course.. but you need to be running a rooted/custom ROM. You can usually mess with the audio configuration files in the /etc folder for whatever audio amplifier chip is in the device.
I use an app from the play store called "equalizer" to accomplish what you're looking to do, works perfect:
https://play.google.com/store/apps/...sImNvbS5zbWFydGFuZHJvaWRhcHBzLmVxdWFsaXplciJd
Just do a custom setting, and instead of doing a typical EQ curve, just boost every slider by the same amount and this will give you a volume boost.
