Hi,
I've purchased this cheap, but good cans yesterday and the volume is extremely low on the Transformer (Stock) and good as it should be on my Desire (Root, MIUI, but no Volume hack) and on my friends Desire S (Stock).
What can be the problem with my Transformer?
Edit:
Using Default Music app and Poweramp (purchased) makes no difference.
the higher the impedance (in your case 24 Ohms) the lower the volume. if you plug in some 8 ou 16 ohms earphones the volume will be "louder".
Being a music addict, I suggest you buy a headphone amp rather than using "volume hack" or a pre-amp gain (as poweramp) those will kill your sound.
I have some AKG K518 and yeah the volume is always at 14 or 15 but I would'nt have it louder, plus mine are at 32 Ohms......
Strange is, that my second headphone (Allen&Heath Xone XD-53) is working just fine and it has 36 Ohms impedance - it have the same loudness as on the Desire.
Software related issue - Checked today with the A&H ones and not as loud as before
Hi I have a regular Galaxy S6 G920F and I wonder if I can use relatively high impedance earphones like Beyerdynamic iDX 160 iE (47 ohms). Generally what impedance does this phone supports without amp and what happens if I use higher impedance? Do I simply lose just volume or...?
Additionally is there any software trick like audio mods that can help (similar to overclocking CPU or raising USB charge amperage)
I'm particularly interested in getting those iDX 160s because of balanced sound and availability in my country.
Thanks
The S6 doesn't really have much trouble trying to drive stuff up to 128 ohms. And to answer your other question, you'd just have a harder time trying to hear stuff at higher impedance. I own a pair of DT-880s (250 ohms) and it's a bit difficult to drive these without something like Viper4Android increasing the maximum volume output.
Thanks for your reply. So it only affects volume and not performance? (bass, mids, trebble, etc)
Oh 47 ohms is not a problem. My S6 can drive my ATH-M50x (38 ohms) quite easily, and have plenty of volume left beyond what I consider already loud and safe for extended listening. I have a friend with DT-990 pros at 250 ohms and if I'm not mistaken he told me that it drives them well enough. They won't get loud at max volume, but that's its good enough to still use in relatively quiet environments.
Agreed; my Sennheiser HD598 at 50ohms gets more than loud enough, and sound great. The S6 will have no problem at all with the other set.
Performance wouldn't be hindered, but without having a decent amp to drive it, you wouldn't be able to get what you paid for essentially.
Using the DT 770 pro 250 OHM and it works really well!
My Macbook Pro (early 2015) on the other hand, can not handle it. its pathetic.
Volume wise with current soundmods availble I would say yes, you can go till 250 ohm with everything maxed out...
But I have the feeling with my dt 770's (beyerdynamic) for example are not driven properly to sound good to my ears compared to my Soundblaster Z and Xonar essence card which is designed to drive high impedance phones.
Let's say music ""gets more on background"" sounding thinner" "losing thons of soundstage""
As I have almost not found any Phone on the market (except the N8 and some chinese brands) who can drive high impedance phones properly I would say the S6 is somewhere inbetween, not bad but not good either.
You will get alot of better results with cheap low impedance in ears who are actually worse than the headphones mentioned above, just because they are driven properly. I hope this helps you
I have a Dasaita PX6 4gb/64gb with DSP running android 9.
It seems like the subwoofer output is very low, I performed a standard subwoofer amplifier RMS tuning,
Disconnected Subwoofer from NVX Amp, Played a 50hz test tone, and turned up the volume to the maximum on the Head Unit. Then measured the speaker output of the amp with a multimeter. Even with the Level turned up to maximum, I only got about 9 Volts. I'm expecting an RMS level of around 34 volts (sqrt (2ohm * 600RMS))
I checked the settings in the "Amplifier" app and the subwoofer gain was turned up all the way.
With the volume on the stereo at a reasonable level, I was only getting 1-2 volts output of the amplifier.
Anyone have any ideas? is this a DSP/software problem Dasaita needs to fix?
Ive got similiar problem. Any advice how to get biggher preamp for the RCA connections?
I ended up buying an RCA line input booster, like this one
https://www.amazon.com/dp/B003LWV77Y/ref=cm_sw_r_other_apa_i_ARwjDb2NE3SJX
and that solved my problem. I think the voltage that the DSP is putting out is just way too low for most amplifiers to detect and isn't getting past the amp input gate.
I think this is a software fix Dasaita needs to make if their hardware can handle it.
I just installed my head unit and now my factory alpine subwoofer in my wrangler does not work... any ideas?
@hotaudio we have at least 3 people here that are having subwoofer output level problems, can you comment?
Has this gotten fixed? I am looking at buying a PX6 4gb/64gb desaita for outlander Phev 2014.

No updates that I am aware of. Again I was able to work around it by buying a line level booster.

What have you measured the line output to be at 0db to ascertain 'problem'?

I thought I performed this test with a 0db 50hz test tone, I measured 9volts on my amp speaker terminals, with every volume turned up to maximum (amp, head unit, bass boost etc...)
I expected to be tuning my amp to around 34 volts. After buying the line output amplifier, I was able to accomplish a standard amplifier tuning procedure.
If there is another test I should be performing let me know how to do it. Thanks.
You really need an external aftermarket amp if your expectation is having base. These units dont have a strong amp despite there being a sub out. I have an xtrons. Basic sound was ok, with a jbl amp behind it its mental. Even on the stock speakers. There is no head unit i know of that has good base(sub) out without an external amp.

That's interesting! I have zero experience with car audio, but love good sound...what amp are you talking about specifically?

Sorry if I was not clear, I do have an external amp 750w NVX.
Just to get the sub signal to pass the noise gate so the amp functions, I need the line signal booster on the sub output. That is unacceptable for the price we are paying for a product like this.

My unit dasaita max6 that I have ordered but not received yet is supposed work with the cars Rockford fosgate system so I imagine it will feed the amp since the RF-amp is a separate unit from the original head unit. So hopefully that won't be an issue... Anyone else with this setup that can confirm/not confirm this working properly?

Most amplifiers have what is called a noise gate, which basically doesn't let the sound through until it reaches a certain threshold (voltage). I guess it would depend on how your car sends the subwoofer signal from the px6 to your amp. If it uses the sub rca jack then you may run into the same issue.

Hi
Do you know the type of the DSP chip?
I have similar problem with isudar h53 unit. The subwoofer voltage lover than the 4 cahannel voltage.
The filter can be adjusted but the gain not works on sub channel.
DSP chip BU32107EFV

I opend the head unit and checked the chips. In my case the dsp chip was on the back side of main board.
Yesterday I added a signal amplifier for two front ch and the sub ch. Now I can got 3,6V without distorsion of the two front ch but the sub ch at same volume ~2,1V. Checked 50Hz test signal. At the moment Im waiting for the seller response, what about the loudness control and sub gain control why they not work.
Did you get an answer from dasaita about this?

I have the same problem with my sub out channel on my PX6. I upped the gain on my amp to compensate. I have a audio control amp with distortion indicator and cranked it up to about 80% gain without distortion to get good sound out of my subwoofer.

Yeah the RCA sub output didnt have enough to turn on my AudioControl amp either. I ended up running the remote turn on wire to the fuse box an tapped there for switched power.
I know this issue too.
Is this caused by the hardware in the radio or is this maybe some software issue? Firmware or MCU maybe?
I have a passive 3.5mm adapter (one without DAC or amp) and looking for a wired headphone. However, I cannot find detailed audio specs of OnePlus 7 Pro, especially regarding to output impedance (ohms).
VE Monk Plus is what I want to buy but since I don't know how much impedance OnePlus 7 Pro can drive, I wonder if it can drive the headphone well (able to get it loud enough). It needs about 64 ohms to work best.
Anyone has experience with high-ohm headphones? What is the upper limit I should consider an active adapter instead?
How loud they will be, it depends on many factors, not only the output of the phone. I would say, if you want really loud, don't go higher then 32Ohm's. Also, look for headphones which have higher sensitivity "XX dB/mW".
I'm not a loud listener but if a headphone requires me to crank the volume up all the time that would be pretty annoying. VE Monk Plus boasts 64 ohms and 112dB/mW. Do you think it can work well without active DAC or amp?
Thanks
Has anyone noticed the max volume out of their headphone jack is typically very quiet, but at times will top out at a normal max volume? I use an aux cable to hook into my car stereo and always have my phone set to 100% volume. My Note4 and Note8 both play at identical volumes with the same MP3 files, but my Pixel 4a is significantly quieter. With the windows down, I turn my car volume up to 11 (normally) which is quite loud. On the pixel? The car volume at 18 is ALMOST that loud, but at that point is overworking the amp and degrades the quality substantially.
Here's what's weird. At random times the Pixel max volume will actually be slightly LOUDER than that of my Notes, again with the same MP3 files. When this happens, if I unplug the aux cable and reattach it'll go back to being quiet. This issue is system wide and doesn't affect just one app. YouTube, VLC, etc. all suffer from this. Has anyone had this?
I noticed it too on my 4a today when I tested it. My Nexus 5 and Pixel 1 also both had that issue also. Sometimes unplugging and re-plugging "fixes" it temporarily.
A good simple fix is to get a USB-C -> 3.5mm headphone adapter. Best Buy sells the Google branded one for like $8 - $13 in-store. I dunno how good the other brands are, reviews seem mixed when I looked on Amazon awhile ago. With the USB-C headphone adapter you'll get consistent and considerably more volume than the headphone jack. I also think it sounds a bit cleaner, too. Not much else you can do aside from some sort of bluetooth -> AUX adapter.
I have noticed this exact issue on both my current Pixel 4a 5g and even my last phone which was the Zenfone 5z. It's almost like the phone will switch gain from high to low when plugging in headphones, but sometimes will fail to do so resulting in a higher level of volume and scratchy audio. I may follow advice above and try a USB C adapter. I have not found a fix in software for this issue. The only "resolution" is to replug the headphones in until you notice the output volume is lower/cleaner.
Yeah. I can agree with lower volume. But i have one more problem after plug jack. When in song coming to louder parts, my player stops. Theres no notificiation about ears damage or like that. After that i need to press play and then its quiter.
Someone have simillar ?
The headphone jack is not very powerful on this phone, it's something like 0.3v? You need to use a DAC or buy a phone with a better headphone jack... the gold standard has been LG (RIP) and even iPhones back when they used to have headphone jacks. Now it's Samsung but they seem to be dropping whatever ports they can too.
I don't know how about you, but think they finaly fix this issue with new update. Nowy my jack works fine. Someone can confirm ?
