Hello! tell me, please, I have connected Gobuz. the player sees the tracks but does not play them. writes -( HTTP error code : 400 ) Invalid request

Make sure you set the correct Date/Time in the settings then retry Qobuz.

Cheers!!

How do you set time/date - for the life of me I couldn't figure it out: it is impossible to press anything in time/date configuration screen, and buttons don't change digits either. I was certain that this is another firmware bug and that nobody could do that either.

I am not near it right now but "if" I remember it was scrolling using the screen, I will check when I get home.

Cheers!!

I feel somewhat embarrassed that I didn't understand it myself - indeed, this works, thanks!

 

[sergius789]

Hooray, thanks, Everything worked!

Restart player and sign in again

And which charger is better to charge?

And which charger is better to charge?

Anything that can provide 5V, like a phone charger. It can charge at 1.5A, so preferably get one that can provide 2A at least.

@LyuboA Not sure if you've tried this yet but I wonder if it will be the same observation on your unit.

I noticed I could get around the same loudness with the same IEM on a USB dongle connected to the V3 with just 20/100 on the slider, compared to 45/100 from the V3's 3.5mm output with high gain turned on. Even though the dongle is a lot less powerful.

Guys, if you've tried this out yourself too, please do feel free to share your findings. Try it with a simple style dongle like a CX Pro, VE Odyssey or the one from Apple.

No i haven't i don't have any dongles only BTR7 and BTR15
but i have tested the 3.5mm output and i don't see any difference in power compared to the 4.4mm which is very strange it should be less powerful but it's definitely not atleast on my unit and i've just tested with BT and WIFI with 0 to 100 volume with the slider from the drop down menu sometimes you can hear a small pop when you 0 to 100 with the slider but definitely no hizz on both 3.5mm and 4.4mm i tried with several IEMs it's dead quiet i even tried with some external amps like Topping L30II, Fiio K5 Pro AKM and IFI Zen Can same result i've also loaded over 11 000 mp3, flac, aac, wav and some mqa files on my 512GB card everything works fine all files one folder deep are detected the first time without any issues plus mqa files all work great even on Tidal i heard some DAPs have issues with mqa

Apparently someone measured it (see below; from 4PDA thread) and I assume the current and power figures are for a single channel. Not sure if peak or RMS though. If those are peak figures, the 3.5mm output would be around 70mW(RMS)

Corrected measurements have appeared. There are only 205 mW at 32 Om on the balance in High Gain mode! Tempotrek are just liars
There is a sharp current cutoff. Optimal headphones on a single from 32 Om, on a balance from 50 Om.

well of course they are what company Dosn't lie although if those numbers are right then Fiio has stated correct number for BTR15 cause to me BTR15 has two times the power of v3 on 4.4mm which is just insane how much power that small thing has

This explains something that puzzled me very much: I just tested battery time on power hungry planar IEMs (Letshuoer S12 Pro) & on very easy dynamic driver IEMs (Simgot EA500), using high gain balanced output for the first & low gain 3.5 on the second (with BT/wifi off, no EQ or mseb, volume: 30) - and both emptied the battery from 100% to 0% in 11 hours, which was very unexpected: on Qudelix, the difference in usage time is almost 3 times (~6 vs ~17 hours). The data above explains it.

Maybe Tempotec not just lied about output levels, but actually made 'balanced' output a regular non-balanced output with 4.4 socket.

Are you sure about that? I assume you are comparing the V3 to the Qudelix 5K: the V3 has a 3500mAh battery vs. 500mAh for the 5K (manufacturer data, probably lower in reality). The 5K battery is 7x smaller, yet your playing times on the 5K are not 7x shorter. What your data confirms is that most of the available battery capacity is used by the V3 CPU & screen, only a small part is used by the DAC & amp That’s why there is not much difference between a power-hungry and an easy to drive IEM.
With the 5K, it’s the opposite, most of the (much smaller) battery capacity is used by the DAC amp. and that’s why there is a significant difference.

Got my V3 today and first impressions are good.The build quality seems much better than in the pictures. The screen is as good as it needs to be. Just not a big fan of that card slot.

I haven't connected it to the internet,i've just thrown some flac files on an microSD card.
Out of the 3.5mm jack it sounds pretty great with my Prestige LTD and some EQ.

I won't do any streaming until a proper firmware comes out. But as a flac/mp3 player ... it's quite nice.

Initially I also considered this possibility, but after some thought understood that it doesn't explain this case. First, during my tests the screen was off 99% of the time.
It was on for at most two minutes during the whole test - I turned it on only a few times for a few seconds at a time to see the progress. In addition consider the following: 3500mAh is almost a capacity of an average cellphone. Moreover, cellphones use a generic mobile processor which due to a requirement of being generic is much less power
efficient, they have gigabytes of memory and a lot of power hungry chipsets, and big high-resolution screens. In spite of that, with all those features (cell/bt/wifi/nfc)
turned on and many background processes running all the time, they succeed to hold for a few days with many hours of things like music listening, a few hours of screen time etc., while V3 has Ingenic X1000 CPU which is a quite specialized embedded processor, with a tiny amount of memory, with every feature (wifi/bt) turned off, with no screen time - and still it gets only 11 hours. With my phone (5000mAh) on a single battery charge I get more screen time watching hi-res videos over wifi than that. And all the V3 does during this time, is playing a simple 16/44.1 flac file - which is an extremely easy non-demanding job for a processor.

Therefore, the only major battery consumers here are DAC & amp. You just cannot waste so much battery in any other place.
