· High-performance AK4490 DAC


Responsible for digital-to-analog conversion is the AK4490, allowing up to 384kHz and DSD native decoding. Its implementation here lets you easily hear every small detail in your music, and provides higher SNR and dynamic range than with the Bluetooth build-in DAC and with better DAC than similar transceivers. Film capacitors work with the AK4490 for clearer and more transparent treble.


Dual Hi-Res Certifications

Not only does the BTA30 have Hi-Res Audio certification by the Japan Audio Society, it also has achieved Hi-Res Audio Wireless certification for guaranteed excellent performance.


vintage speakers

What happens if an older amplifier/speaker doesn't have Bluetooth for wireless, hassle-free music? Simply connect the RCA output of the BTA30 to the RCA inputs of the amplifier/speaker – now you can play your music over Bluetooth through your older amplifier/speaker, giving it new life!

Bluetooth jukebox+DAC plays a new trick


Want to directly connect your DAC/audio decoders to any smartphone? Simply connect the optical/coaxial out of the BTA30 to the digital input of your external DAC to allow it to decode directly from your phone.

Computer audio assistant

Get great sound from your computer too! With the USB DAC functionality, transmit high quality sound from your computer to speakers or Bluetooth headset through the BTA30.

Full theater immersion

Connecting the BTA30 to your TV’s SPDIF/optical out allows you to send low-latency sound to your Bluetooth headset, allowing you to be fully immersed in your own private theater.

Exciting gaming

 (game console-TV-headset)

You need to fully enjoy any gaming session you get! By connecting your game console via optical out to the BTA30, you can directly send wireless sound to your Bluetooth headset via the BTA30 for more enjoyable gaming.

Listen to your favorite music with your cherished ones. In Bluetooth receiving/decoding mode, two devices can connect to the BTA30 at the same time, and both devices are remembered after connecting for the first time. Music from either device can be switched between freely to play on the BTA30. In Bluetooth transmitting mode, the BTA30 can send music to two different Bluetooth devices at the same time.

Share the fun around

Convenient intelligent interaction

Your smartphone, when connected to the BTA30, can remotely control it via the FiiO Music or FiiO Control APP to make your life easier.


1. Channel balance

2. 4 types of audio filters

3. Bluetooth format priority

4. Switch on/off LED indicator

5. Volume adjustment

6. Set fixed output volume

For its Bluetooth connection, the BTA30 uses an external gain antenna to make full use of the CSR8675 chip’s abilities. With Bluetooth 5.0 support, this all means faster connection speeds and more stable transmission signals, with a  range up to 30m under normal usage conditions.

Good sound everywhere

1. Bluetooth receiver-RX


When connected to a smartphone or music player with Bluetooth, the BTA30 supports the LDAC/aptX/aptX HD/AAC high-resolution formats. LDAC specifically can support up to 96kHz/24-bit audio, superior to CDs.

2. Bluetooth transmitter-TX


When connected to the digital outputs of devices like TVs, CD players, external DAC/decoders, and computers, the BTA30 can transmit those signals as the LDAC/aptX HD/aptX LL/SBC Bluetooth formats – for ultimate convenient listening pleasure.


* The LDAC format is only supported to transmit through optical/coaxial input, but not USB input.

3. Digital decoding-DAC


The BTA30 can also can be used as a pure digital-to-analog converter, to convert your digital audio signal input to high-quality analog audio output. Coaxial input supports up to 192kHz/24 bit and DSD64 native decoding; optical input supports up to 96kHz/24 bit decoding; USB input supports up to 48kHz/16 bit decoding.

The strong aluminum alloy body gives the BTA30 a luxurious shininess along with a silky-smooth texture. The neat and uniform button arrangement makes it easy to use, and coordinates well with other audio equipment.

Its beauty only adds to its strength
