Audio output on Qtec s100 - JAM, MDA Compact, S100 General

Can anyone tell me what's the output power in mwatts per channel to headphones on the Magician? Thanks

???
Is there an answer to this question? I just want to know if it makes sence to upgrade the device with better headphones straight out or is it not worth it. THanks

I did 'upgrade' my headphones and everything's working fine.
I opened the plastic case where the earplugs come out, desoldered them and replaced with brand new pro Sony earplugs (~30EUR).
Audio playback quality has improved dramatically.
You may want to install a female mini-jack plug, instead of soldering your earplugs, just in case you need them somewhere else.
I hope it helps.

Thanks for reply
I figured that stock headphones work well together with Bass & Treble enhancement. I was also wondering if the Magician will be able to power better headphones, something like Koss Porta Pro, Grado SR60, Shure E4.

I plugged my SHURE E5c earphones on my S100, it's outstanding,
music restitution is close to perfect.
I used an adapter 2.5/3.5 from PocketPCTechs.
Half an hour music takes the battery meter down by less than 5%.
Playlists are stored on SD cards.

Very Strange Audio Output problem on the 2.5mm Jack

Hi,
I've noticed an audio output distortion of some frequencies when listening to music, in the sound coming out of the 2.5mm jack.
When the speakers on the device is used, there is no problem.
When I plug the headphone, there is sound output, I hear the music, but some frequencies are lowered so much that I can't hear the singers voice. When I unplug, the speakers work fine and I can hear the singer again.
In additon that, most of the background instruments can be heard as well as the backvocals, if they are female.
It's like the sound is being processed (like an equalizer) when I plug the headphone, some frequencies are lowered, given some echo, reverb etc.
I don't understand how this is possible. I am thinking of a hardware contact problem, but it's hard to believe if this is a hw problem.
I've tried two firmwares (2.16.x, 2.25.11.1) and made hard reset also. No result.
Any ideas?
Note: I can try to actually record the sound tonight if anyone wants to hear.
Best regards,
Fast
maybe try a different headset first?....could be a short in the cable, because what you are describing is a phasing issue with the headset speakers......
Thanks for the response Kiru,
Just tried a different headset plugging it into my HAMA 2.5 --> 3.5 adapter. same result.
I will try the original headphone came with the Wizard. If the source of the problem is the HAMA adaptor, this should resolve it. (i hope it is)
Could you please elaborate on the "phasing issue" ?

Hmm....how can I explain.....Let's start with the speaker itself. A speaker has two terminals on it, one postive and one negative. What we want is to have the positve from the source (ie. Amplifier) to the positive terminal of the speaker, and the same for the negative. Since there is a pair of speakers, we want them to be hooked-up correctly. If hook-up correctly then the speakers are in phase with each other, and this is called constructive interference, hence in phase. When ONLY ONE of the speakers is hooked-up backwards, we call this destructive interference, hence being out of phase. Being out of phase causes frequencies to cancel or sound muffled. Hope you kind of get what I mean, but I highly doubt that this is the problem with headphones because heaphones nowadays rarely get manufactured with this problem. This is just the electrical part of phasing. Also, you can have one speaker, and it could sound out of phase because of the distance it is firing from walls or the shape of the room due to the reflections of sound, this is called acustical phasing.
A short in the cable, meaning the positve and negative wire are somewhat touching, can cause a similar effect, and I suspect that this is problem for you. As you now state that you are using an 2.5 to 3.5 adaptor, I would agree with you that most likey you have a faulty adaptor.
Hope this helps! and keep me posted!
Hi again,
Thanks again for the explanation Kiru, I know a bit of electronics so I got the problem.
However, I'm now home and tried to original headset, no result. The same problem is existing.
This makes me believe that I've broken something inside the Wizard which shortcircuits something. I'm very dissapointed.
Maybe the only way is now to buy a stereo bluetooth headset...
Thanks for your help
Any reason that you can't return to orange for repair/replacement?
PROBLEM SOLVED
I got this unit from priceminister second hand. It's origin is not France, I don't have a purchase receipt neither.
By the way, I solved the problem. I disassambled the unit using the info given in one of the posts in the forum. I played a little with the contacts, there was oxidation in the outer solders, i cleared them up etc, it 's working at the moment.
I'll post some pictures afterwards.
and I hope i will be able to reassamble it, I already have a piece of thing which I don't know where to put
I got the same problem. Was working fine for 2 months then all of a sudden the headphone plug is all messed up. Volume is all distorted I can sometimes hear a song but quality is no where near the original. Usually everything sounds echoed. I think something is wrong with the plug
I've had the same problem. The headphone jack on the Wizard is crap. If you have your Wizard in your pocket with an adapter, as you move, the adapter pries back and forth on the jack. This breaks the cheap jack.
If you want to listen to your Wizard as an music player, you should invest in a nice set of bluetooth headphones and only plug the jack in when the wizard won't be moved around a lot, like a home or car stereo.
I recommend Nextlink Spider headphones. They double as a headset and you can navigate through your library with the button on them.
MUSIC Speed
I got the same problem here. The SE stereo btooth headset isnt yet in our place.
Anyway, i experienced this one with ROM2.16 Imate. The sound speed or music speed seems to being played faster than normal. But when i tried to plug the 2.3-3.5 adopter and quickly pull it out, the sound is played in normal speed then. strange.....
are you all sure that the wizard has a stereo output ? I thought it was mono.
Anyway you can get earpieces and headphones with a 2.5mm jack so you don't need a 2.5-3.5mm adapter.
Maybe the contacts on your jack are not connecting properly with the internal contacts of your adaptor

Why cant I use speakers or tape deck adapter without my HD going nuts?

Hey odd question, lately when I plug in speakers or a tape deck adapter to my HD 2, it will close out whatever program switch to music, then it will cycle music like crazy. Kinda like if its getting a signal to switch tracks etc. Anyone know what could be causing this? Using Energy Rom.
Because the HD2 uses a headset with media controls, and most likely it is getting false signals from your speakers, also the headset jack is a microphone jack not just speakers, you cannot just plug stereo speakers into a jack that has contacts for , controls, mic , and sound ...
Thats odd when you say that tho.. cause I use use Nokia MD 4 (With the FM ant able in the cord) http://www.newegg.com/Product/Produ...9&cm_re=nokia_speakers-_-75-975-079-_-Product
The HD2 works fine.. just anything else messes it up. So what is everyone using in the car and so?
I plug my FM transmitter into the headphone socket in the car,and use
2 different types of headphones,a generic in ear set and some
folding Sennheisers,neither give me any issues,they just work....
I use a set of travel speakers plugged straight into the HD2 speaker jack & everything runs fine.
I plug it into my stereo and it works 100%
I sometimes get the crazy behaviorwith common headphones. It's fine 99% of the time, but sometimes in the pocket the plug will start doing some bad contacts, and then it starts switching tracks, or even calling the last number...
Need to remove the headphones, wait a moment till it processes the ton of "false commands" that were sent, and plug again. Sometimes a reboot is needed too.
Youd think there could be a fix or on cooked roms a way to disable inputs from the headphone socket.
I guess I should have been a little clearer what I said, ...
and yes I typed it hard to understand ....
Some speakers work, some don't , some will give you false inputs, others will not ....
Most small portable speakers will not ...
I tested this theory just a little while ago ...
My regular headset from my mp3 player works fine ...
1 out of 2 sets of computer speakers I have makes my HD2 freak out ...
I tried my travel speakers again and they were fine, so I have tried my brothers portable speakers that are a different make, they too work fine. I have just tried it with my big house speakers and again fine.
Thinking about it, my Omnia & my HTC P3600 both came with headphones that had a microphone & control buttons on & I never had any problem plugging them into any speakers, same as I don't with my HD2 so I'm sure it can't be the phone & must be a rom issue or something like that I guess.
Sorry I can't be more helpful with an answer, but hopefully the tests I've just done will help in some way.

[Q] Playback through Car aux connection

I play audio podcasts through car's aux in and just plug in the other end to my Focus's headphone jack. I have noticed that many times the podcast suddenly lowers volume to nearly inaudible levels and happens intermittently.
Once the problem shows up if I
- play songs, the volume level is fine
- stop and start playback of podcast, the problem persists.
- unplug and continue playback on Focus' speaker, the volume level is just fine
- unplug and plug it back in and the problem goes away.
- never have this problem when playing back over headphones (when in gym)
I have this problem only with Podcasts and don't get it at all with songs or videos.
Anyone else noticed this?
Audio output sucks on this phone, that is for sure. Major issues. Sorry to hear about yours.

how so? i'm not having any problems at all.
Did any of you notice it's not your standard 35mm jack? The headphones that come with the phone are clearly deeper than the standard jack, and have two bands around it instead of the normal one.
I presume you are using standard cable to connect to car's aux jack....
I would check to see if there is a special samsung accessory to make the proprietary jack into a standard aux output?
Samsung are notorious for using this style of jack on their phones. The Galaxy line of android phones use the same jack.

that is weird. i hook mine up to my car with the same jack i used for my iphone with no problems. in fact i am under the assumption the sound quality is actually better than with the iphone.
maybe this is a canada thing?
The plug is set up to use headsets with the microphone, and may not work well with some older stereo audio cables. However, I have used it with a podcast and found it to work quite well. I suggest trying another cable, cuz the Focus works fine.
The line level output of the 3.5mm jack is approx. 40% less than that of the iphone, or my HTC Tilt2. That is the issue I have and that others have commented on.
For instance, iphone plugged in playing on my car stereo, Panteras Cemetary Gates @ 320kbps MP3 is mind boggling loud at 50% volume on the car and 100% volume on the iphone. With the Focus the car stereo volume needs to be at 90% to be equal to the volume of the iphone.
Also, since the Focus needs to be at 100% and the car stereo nearly 100% you hear the phones whining, hissing and popping and every non-music portion.
Super lame.
There's some volume problems that I've noticed on the Focus, in that it's not consistent through playback sessions and such.
The iPhone 4 uses a Cirrus Logic codec with an integrated headphone amplifier, the Focus seems to use the built-in codec with it's headphone amplifier, which might not have the same amount of oomph.
I've measured a 7-8dB lower volume on the Focus when using a line-out cable to an Audio Precision test machine.
Thanks for reporting that! Great post.
Does anyone have this problem?
Ok, I have a mp3 car adaptor that I used with my Tilt and Tilt2 without any problems. Rich sound and bass. I plugged in my Focus (just got it last night) and music only comes out one speaker.
In my '95 M3, I run an Alpine HU (9814 IIRC) with a Line in Adaptor, I run very HD (thick) gold plated lines and a Splitter (all from Monoprice.com, one goes to my portable Sirius, other pops up by my center console sunglass cubby, split happens under the passeger seat) and I usually have my 120Gb Zune attached to it, but I tried with the Phone the other day and it worked great. Played a Tool concert and it sounded as good as the Zune. Like the Zune I set the volume to about 80%, still had plenty of head room for serious volume in the Alpine. (only way to listen to Tool is LOUD!) I do run an old school Pioneer Amp, Pioneer Kevlar Components, 2 JL Audio Stealth Boxes (each is an 8" Sub).
I want to escalate this issue but I need you guys to quickly reply on the MS forums so that it gets taken seriously. Please hit the "I need an answer too" button and give some sort of descriptive reply.

I hope that his is a software side optimization since we are able to make the volume higher with the diagnostic codes.
I added my vote there.

I have a second complaint. When I stick a headphone jack in the mic turns off, it probably is expecting an inline mic with the headphones. My problem is when I then go to pull out my headphones the phone doesn't notice and will continue to not hear. It takes two or three times reinserting and pulling out the headphones to remidy this. Is anyone else haveing this issue.

Same problem here. But is worst, I connect the Focus to my Car Auxiliary jack to use it as a mega speaker, I mean, when someone calls I can hear them, but they can not hear me. The microphone is dead when I plug it in. Someone knows a fix for this?

Can't say that I have a fix for it, but it may be the connection your cable is making with the jack in the phone. I do the same thing, have the phone mounted in a jack around the same height as my head unit and people hear me fine when I speak during a call. I am currently using a cable from radioshack designed for recessed headphone jacks. Can't think of the brand off the top of my head however.

Hi pal, thanks for the reply, but I couldn't understand very well your explanation. What is a recessed headphone jack? What is the head unit?
Thanks in advance!
I have not noticed this problem however the microphone shutting off is very annoying and funny since at&t says texting while driving is unsafe yet i have to unplug my phone while driving to turn on speaker and talk. they need to fix that ASAP

[Q] Less volume in one earphone speaker

Iv'e got a 16 gig N7 with me about 7 months old with a peculiar problem
When listening to music/playing games/pretty much doing anything with sound if I use a earphone with the 3.5 mm jack I get low volumes in the left ear than in the right ear.
I've tried the same earphone with an iPod, my cell phone, and another mp3 player but the volumes are equal so it's neither the headphones nor my ears.
Any help will be appreciated.
Make sure the headphone connector is inserted fully into the jack. It may take more force than you think. Also, try different headphones or earbuds in the jack to see if it duplicates the problem.
If it's in-ear 'phones (not earbuds) try adjusting the fit and how far in your ear you insert them. I have to do that sometimes for my left ear.

I have this issue too, and it has started about 2 months ago (had the device about 10months now). Tested with multiple headphones, and other devices (galaxy S4) works fine.
I'm not sure if it's specific headphones, software, or a full out headphone jack issue.
Less volumne in one ear
I have had the same problem develop after owning the Nexus 7 32 gb for two months.
Could get earphones to work if I did not completely insert into phone jack but that was a PIA.
Tried many types with same results.
Almost sent it back but everything else was perfect with the tablet.
My solution was to purchase a:
GOgroove BlueGate Bluetooth Adapter Wireless Receiver
It paired right up. Used it on a recent flight to watch movies on the Nexus 7. You can use any standard earphone and they are not tethered to the Nexus 7.
It also solved the volume problem with earphones. Sound is now loud and clear.
I also use the adapter to stream internet radio from the tablet to a little used bookshelf stereo with great results.
Also use a G-Grip Portable Wireless Speaker to listen to music and audio books. Nice little speaker.
My one year warranty will be coming up soon and I must decided to send it back or live with what I have.
Seems like a mechanical/connection problem.

LG G6 (870DS) DAC DoA?

Hello folks, got the G6 via mail today and everything was fine until I tried to enable the HiFi dac and then I was devastated.
It played music just fine then I switched on the hifi and it would pauce but instead of playing again it stops and all I get is a hissing noise with some weird dial up Internet sounds
Am I missing some box I was suppose to tick? I factory reset and it did not fix it. I feel it's a hardware issue and needs to replaced.. thoughts? What's wrong?
Here's a video of the problem: https://youtu.be/1Y62BTECLy8
All comments appreciated, thank you
i think you can not enable the dac while youre headpone is connected , you should first enable it and then when you connect your headphone it wil recognize the impedance and then the dac is automaticly enabled
hmmmm ... on low-impedance earbuds, it doesn't come on at all, although i can enable it and it does nothing. on high-impedance headphones it comes on automatically.
no the dac is made for 80 a 100 Ohm and higher offcoarse
I want to put your mind at ease. This happens to me sometimes. What kind of headphones are you using? If they don't have an in line mic then you can sometimes get some weird sound cutoffs with it. This has to do with the headphone jack being a "smart" headphone jack. The headphone jack has to detect impedance after all so it has to have some tech that won't be in your run of the mill headphone jack. Trying plugging in something with an in line mic just to verify and also you can trying jiggling and rotating in the jack with your current headphones a little bit.
This happens to me occasionally when I try to use aux cables in my car. It can get weird. It also sometimes interprets movement of the aux cable as pressing the pause button on an in line headphone mic controller etc. I wouldn't be worried about it until you troubleshoot this part.
Attach a 50 Ohm or higher headphone and the DAC will be available.
Headphone used is the ATH M50x
I got hope from your posts, went to a nearby store to try out the G6 they had with my headphone
Theirs had no problem playing with HiFi Dac enabled with the M50x, so it definitely is my units problem which sucks.
*Update*
Where I live, India, LG thankfully has a DoA program (10 days) where they replace it new at the service centre after a bit of formalities are done. Good news, I'll get a new replacement through them instead of shipping the phone to the original seller (with my money) and getting a new replacement from seller.
Just to double-check...
Guys,
I'm in the process of buying a smartphone mostly for the sound quality (so I can ditch my Nano), Wifi, screen, waterproofness and GPS functionality as I'm a semi-permanent traveller. I have expensive earbuds that I'm very happy with and that I'd like to keep, having compared them with 25+ (?) others. HOWEVER... Am I interpreting these messages correctly if I start thinking that with my 16 Ohm (@ 1kHz) finding any audiophile quality on a smartphone is just a pipe dream?? That would be terrible news...
