No, the knob only works over RCA out. Over BT you have to control it on the receiver

It works with optical too, I use my hifiman deva with the bluetooth module and the volume knob it's working when using the BTA30 in Tx mode.

Hi! I'm new here.

I would like to know if I can control volume of my connected BT earphones via BTA30's volume knob in TX mode ( USB In / Coaxial In / Optical In )?

Thanks in advance!

Hi,

I think it has been stated that the volume knob will work if you have coaxial or optical input, but not if you have USB input.

But I can be wrong...

Regards.

Hi,

This is super funny
Why ?
Because I was just about to post something to describe the EXACT same problem

I noticed that this does not happen when listening to music using coaxial cable.
Do you have a chance to test that coaxial input and see if you can confirm what I experience ?

I hope this will allow to narrow down the problem and help FiiO fix the problem if it can be fixed with a firmware update.

If not, then a suggestion for a BTA-50 Add a selector for the source. And leave the thing about priorities of inputs.
That would be nice because :
- at night, I play music with a dedicated music player that feeds the BTA-30 with S/PDIF . Working like a charm ;
- during the day, I stream the music from the computer to the BTA-30 so it's passed from BTA-30 to headphone amp. To stream, I use Toslink. But even if no signal comes out of the S/PDIF input, as it is plugged, no Toslink possible unless I unplug the S/PDIF cable

Don't get me wrong. I can live with that. But that is of course a little less convenient and has a possible side effect : those small interruptions of sound when using Toslink that is probably the last in priorities order.

Regards.

Hello
Thank you for your feedback, we will confirm the issue as soon as possible. If there are any new developments, we will let you know, thank you!

Following up - I have tried coaxial input from my PC (optical to digital coaxial converter to bta30) and the behavior is no different.

Hi,

OK. I'll double check if it does the same here and report.

Regards.

Just a friendly reminder: careful where you plug in the USB for power. I had the bta30 connected to my nintendo switch dock initially and noticed later it adds a lot of noise to the signal.

EDIT
Some further messing around showed that it was actually the fact that that I had two USB DACs connected to an RCA switcher that introduced the noise (1 from bta30, 1 from my desktop dac/amp, output to speakers). The issue is fixed if I either disconnect my dac/amp from USB, or connect my bta30 directly to an outlet (no USB input). Interesting, but only an issue for my specific use case.

Perhaps the ifi iSilencer+ would assist with reducing the noise.

Hi,

Weird, but today that problem with sound interruption disappeared...

Have to double check it.

Regards.

So I I have this setup on my PC. Through SPDIF into the Sony 1000XM4s. Sounds frikken nice after I finally got the bit streaming up. I was coming from the same spdif which was hooked into my amp then to my beyer DT770s. I had some realtek custom drivers that the BTA did not want to play with nice with. I had to revert back to stock and let me tell you it was well worth it. At first it sounded like crud because of the driver issue so if anybody's in that situation then clear out your settings to the bone. The SBC codec sound dang good as well. I have it through fubar wasabi with equalizer APO and a custom piece para EQ. Put anything else I've ever put on my system to shame. I also had put some time in listening to the aux, And there is almost absolutely no difference. The base just seems a little bit more with the aux, not cleaner or smoother just a little more mass which can be good or bad.

That's what it was designed to do, yup. Thanks for mentioning it

Great to see Fiio product manager here! I have just picked up a BTA30 and indeed I really love the versatility since my PC, TV, and stereo system are all in the same place.

Unfortunately, I came across an issue that kind of is a deal breaker for use with a PC: whether using USB or optical in from pc, I find that the BTA30 goes idle as soon as it isn't actively receiving audio (pairing light switches off), and whenever going from idle to audio playing it drops a clip of audio off the start of the sound playing (plus some annoying popping when going in and out of idle). The behavior is such that many notification type sounds (anything just 1-2 seconds in length) just don't get played out at all (just the popping sounds from going in and out of idle state). I made a short video to demonstrate the issue posted here:

https://photos.app.goo.gl/QbpP7DVuXdRvn39m7

I wonder if this is something that can be fixed or worked around or if it is just a design limitation. Ideally you could fix the BTA30 to an input source (and keep it active always) instead of it trying to automatically select a source based on input signal level.

Hello, We check the problems you mentioned before.

About the input switch when connecting to multiple inputs

That is, in TX mode, when there is coaxial/optical or USB input, his priority will be USB DAC input > Coaxial input > Optical input. So when you connect both interfaces at the same time, the BTA30 will misjudge the situation.
But this problem is easy to solve, we have set the input option in the FiiO Control App, you can set the input device to achieve a better deal!

About the signal disconnection when connecting to the PS4

The BTA30's indicator light is able to indicate the playing status as designed. In DAC mode, the light will stay constantly on when there're input signals, and use different colors to indicate the input sample rates. When the input signals stop, the light will start to flash to indicate the idle state.
So, when you see the light switch from constantly on to flashing state, it doesn't mean that the BTA30 has entered standby, but that the input signals have stopped. As mentioned above, some playing devices will continue to output muted signals after stopping playing. But it seems that the PS4 would not. It just directly cut off the output signal. And when the signals stop and then recover, there could be sound dropping issues. We have also conducted tests on the BTA30 and found that for optical input, if the signals from the playing device are complete, the BTA30 can actually keep a stable output.
Also, for Bluetooth receiving mode, it's quite usual that the signal will stop during pausing. And unlike the optical connection, this generally would not cause any issues.

Transient sound incomplete under USB DAC input:
Because of the design of the CSR8675 chip, in the case of USB DAC input, such as using the CSR8675 chip's own USB DAC to decode the device will have some sound loss at the beginning, the time is about 0.6 s. This problem has been evaluated and optimized before, in fact, our BTA30 also better than most of the devices using the CSR8675 chip. And this only exists at the very beginning of playback, so if your playback device has not been muted, it has no effect.

I'm the product manager of the BTA30, and I'm happy for you to discuss it with me. Every product is not perfect, but we try to make it as perfect as possible.

I am really interested in this product and I plan to use the BTA30 with my computer, however, my computer only has USB connections. I found this product:



https://es.aliexpress.com/item/4001010171187.html

Which in theory would let me use the BTA30 with the coaxial input, control the volume, and transmit LDAC to my headphones. Does any one have experience with these type of adapters that converts USB to Coaxial? I am usually not a big fan of adapters and this particular one seems really compact compared to other solutions I have seen, but who ones, maybe it is the workaround to transmit LDAC.

Before purchasing the BTA30 I would like to solve the following issue:

I'm looking for a way to connect my Nvidia Shield TV to the BTA30 so I can transmit audio from the Tidal app (up to 24 bit / 96kHz) running on Shield to my external Bluetooth DAC using the LDAC codec. Since the Shield TV does not have optical/coaxial output (it has only 2 USB 3.0 ports), I need an USB to coaxial converter like this.

First question: Does anyone know if this converter could extract Shield audio for the coaxial input of BTA30?
Second question: Is this converter actually an USB DAC? If so, would the audio data be degraded due to additional D/A conversion?

This is important for my purchase decision, so if @FiiO or @FiiO Willson can answer these questions I would appreciate it.

I also have found another device which could be a solid solution for me:
Douk Audio U2 USB Converter XMOS XU208 Digital Interface

Is this converter an USB DAC too? I would prefer no conversion, that is, BIT PERFECT digital (USB) to digital (coaxial) connection.

Thanks for any input.

I took a look at the product(Douk Audio U2) because it reveals a lot, so I can learn a little more about it
It appears to be a USB to Digital signal device with no DAC functionality.
Its output is still Digital/SPDIF.
In fact, some users of the BTA30 product did suggest us to do one product similar, and we are considering it, but it may take some time to decide if it is worth do that!

I hope you find my response helpful.

The K3 is a great usb to coaxial converter.
I have been using it with success.
