Thanks!
Can you confirm if it gets 24/192 input, will it be compressed before bluetooth transmission? Trying it right now over optical, I get sound with cracking and popping. Is this due to optical limitation, or will there be no difference if I use coax cable instead?

Before the signal enters the Bluetooth 8675 chip, it will undergo preliminary processing. The principle of processing is to choose the corresponding sampling rate according to the Bluetooth format selected by the user, and if you choose LDAC, the maximum is 96k sampling rate. If you choose aptX, the sampling rate may only be 48k.
The processed signal is then given to the 8675 and then output.
As for the sound problems you say connected to the Optical, I suspect that there is a high probability of problems with the Optical signal, you can try the Coaxial input, if the Coaxial input is fine and the Optical input can not, then you can be sure that there are some problems with the optical input device
In our research, we found that the Optical support more than 96k sampling rate, may not be very stable

You can communicate with me directly by private message or Twitter, which will be more efficient

In TX mode, BTA30 Can support Up to 192K/24B input, and Support LDAC/aptX HD/aptX LL/aptX/SBC out, but you know, Even LDAC can only transmit 96k 24bit signals stably, depending on the characteristics of LDAC itself。
Perhaps this feature summary image will give you a better understanding of the BTA30.

Maybe it has been asked before, but are there any plans for USB Input / BT TX mode to support higher bit rate formats and LDAC as well sometimes in the (near?) future?

Due to the positioning of the current BTA30 and the solution used, it is not possible to increase the high sampling rate in TX mode with USB input via firmware. We are very sorry for this.
The BTA30 was designed with a clear advantage due to the definition of the product and the fact that there are no better products on the market.

However, thanks to your feedback, our next generation of products will be even better, so stay tuned!

Would it be possible to have a passthrough mode? I want to put it in between my TV and my DAC so I can receive/transmit and it'd be nice to pass it through when I want to just use my setup wired.

Hi @FiiO Willson

Thanks for your response. I'm disappointed that the USB will not work for me for PC usage in general (it's fine for music and movies, just not for general work) so I would be excited if there were any updates to resolve this, even if it's a new product design. Regardless, it's a cool device and I appreciate your time!

BTW, I'm not able to test this so could you tell me: if the BTA30 is receiving USB input, will it ouput this signal to optical output in DAC mode?

@FiiO Willson : Finally I have bought the BTA30 on Ali, but I have two questions:

1)
I want to connect 2 devices at the same time, a set top box with optical output and my Nvidia Shield TV with coaxial output (thanks to an USB to SPDIF digital interface). Both on TX mode. Therefore, do I have to select the input of the desired device on the FiiO Control app each time I want to use one of these two devices in order to transmit audio to my headphones? If so, could a future firmware update allow the input to be automatically selected as soon as it receives audio data (to avoid manual selection)?

2)
I have a SMSL SU-9 DAC with a built-in BT receiver with UAT support (this protocol supports up to 24 bit / 192kHz audio via Bluetooth). The BTA30 does support 24 bit / 192kHz audio through its coaxial input (according to the specs), so could this codec be added in a future firmware update (at least for TX mode) if there were enough people interested in this enhancement? If so, the BTA30 would be the first BT desktop transceiver in the world supporting this codec. Logically you would have to buy the license from HiBy, but in turn you would increase the sales of this product for sure.

Thanks in advance for your help

For the next generation we will definitely improve the USB input, I can promise

And for your question,in DAC mode, if the BTA30 is receiving USB input,it can ouput the signal to Optical&Coaxial output,and can be upscaled the signal to 192kHz/24bit

First of all,thank you very much for your support
For your questions:
1)
When in TX mode with different signal inputs, the system has a default priority: USB DAC input > Coaxial input > Optical input
When you plug in both the TV and the set-top box, he will give priority to the set-top box input if you have not changed it.
He will only select the TV input when you turn off the set-top box, or when you select it in the FiiO Control App.
I am not sure if you often have both inputs, as it seems that most people do not want to hear the set-top box while using the TV, or turn off the TV while using the set-top box.
Of course, if you feel that this default setting of the BTA30 does not solve your problem, then we can change a version of the test software for you to switch between inputs by double clicking on the power button (only the switch, which may not be shown by the indicator light), which I think would solve your problem and would be slightly more convenient than the app

2)
Maybe I don't think the same as you, if a product has a feature that is not well done, we will even remove that feature, which is responsible for most consumers.
In fact the BTA30 could have been designed to do more, but some were removed because the experience was not good.
This is our brand culture, which may not be the same as some companies.
If someday we integrate UAT, then that will be the time when UAT is stable.

Ah, I understand. The thing is that I have these 2 devices turned on all the time, and I switch between them with the remote control of my AVR. Is it necessary to change the BTA30 operation mode to RX in order to change the current input on the FiiO Control app? If not, it's ok to switch inputs with the FiiO app. However, I appreciate your offer. It would be interesting to have the 'double click' feature for the next firmware version. I can test it if you want. But keep in mind I don't have the product yet, so you'll have to wait.

Excuse me, but I didn't know that. I thought that UAT integration would be feasible but you hadn't added it because there weren't enough people interested. With your last statement, did you mean that UAT could be integrated in the future or only in a NEW MODEL due to technical limitations?

Thanks again.

Our company is now able to achieve a technology similar to "UAT", but it has been evaluated and cannot be applied to our products for the time being to meet our quality requirements and product requirements.

Theoretically we cannot talk about other companies' products or technologies, this is not good, so please try to avoid such problems in the future, thank you very much.

Hi, you misunderstand me. I mean optical input to optical output. So I can bypass the unit without having to replug everything. It's a feature I saw on a few much lower performing units on AE with this feature.

Hi,

I am considering buying the Fiio BTA30 Bluetooth transmitter to pair it with my Fiio BTR3K device but before that I would like to know if when paired together (the BTR3K and the BTA30), the BTR3K is able to go in IDLE mode when no sound is playing as it is able to do when connected to my phone. Multiple transmitters I have tried do not have this ability which uses too much battery for a desktop use and I wasn't able to find any information online regarding this.
Currently, using my motherboard's Bluetooth chip, the BTR3K is able to go in IDLE when no sound is playing (or rather, when no application is sending sound) exactly as it does when connected to my phone. Is this possible with the BTA30 too?
