Shanling UP4 & UP2 - Bluetooth 5.0 DAC/AMP with ES9218P, balanced output, supporting LDAC, HWA LHDC, aptX HD, aptX Low Latency, aptX and AAC.

Bit late to the party, but just ordered an UP2 so my Hiby W3 doesnt feel lonely.
@Shanling Can you tell us what features are being worked on for the next firmware?

And also is it even technically possible(would the hardware allow it) to have an option to disable charging and bypass battery during USB mode? Pretty good thing to have for maximizing battery longevity, so it would be nice to know is there a chance of getting that in some future firmware, even if not in the next one.

We discussed such setting with our software team, but so far no update.

How serious should I take that warning with UP4 that device needs to be used with DC5V 1A or it may be damaged. ? Anyone used other types of chargers?

I usually charge it with 1A chargers. Occasionally I used more powerful ones (40W) without consequences, but I avoid it.

Would DC5V 3A damage it ?

If the specifications are 1A, I wouldn't push it. But I guess @Shanling can better answer this question

It wont, the adapter rating means how much maximum current it can potentially provide. Its up to the device how much it will draw.

If you are using decent charger that can regulate the charge(, it should be fine.

I ordered a UP4 earlier this month, just waiting for it to arrive. I was quite torn between that and the BTR5 and reading all the opinions here didn't the decision much easier . I ended up buying the UP4 as it was the less expensive one

got it in 6 days from China, world record for me, for any delivery from China, hehe. Sounds clean and wonderful, just don't know, how do i turn LDAC codec on> for now it's light violet colour on, all the time

Light violet is HWA codec. For me it sounds as good, if not better than LDAC.
To choose codecs, you have to go to your Android programmer options menu.

Thanks, guess I keep it, then next question, which phase should i keep, Linear slow/fast or minimum slow/fast ?

They sound very similar. I slightly prefer the linear slow.

Loudness is insane, compared to Creative G3 USB DAC, Shanling slays, G3 has to be at 90% of windows volume to give me good volume, as headset is closed back, I understand it might need higher volumes, UP4 doesn't need that high, and even then I can go louder, to the painful listening point, hehe. I will be able to take Beyerdynamic Custom Game headset outside now, as my 3.5mm port worn out, bluetooth is the best way for now

@Shanling Is 1.7.5 last firmware we will get for UP2, or development of new features/firmware still going on for it?

 

[Ufasas]

Is it possible to make internal microphone louder? Also do codecs switch themselves automatically too? Cause on PC i get violet codec, on laptop i get blue codec
