High-definition Bluetooth for higher heights of joy

Innovative volume control for fast, accurate adjustment

The BTA30 is among the first Bluetooth desktop devices to incorporate pro-level audio volume adjustment methods.

Innovation 1: No imbalance, precise control through ADC curve reconstruction

Innovation 2: Can quickly adjust both analog and digital output volume

Innovation 3: Can be remotely controlled through FiiO Music APP

Innovation 4: Fixed output volume setting is available through FiiO Music APP



*When transmitting out from USB DAC input, the volume cannot be adjusted.

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. 

Passionately smooth and suave

The BTA30 with its 3 operating modes is also the first such desktop decoding system to support bidirectional LDAC/aptX HD Bluetooth. It can greatly improve the sound of audio equipment such as your TVs, speakers, and computers to spice up your life.

A truly versatile device

Easy to use, easy to enjoy


Rejuvenate 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!

Decoder for your Bluetooth jukebox

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.

Want to share with someone else? No problem! Under Bluetooth receiving mode, the BTA30 can connect to and remember two devices at once, allowing your access to your favorite music in both. Under Bluetooth transmitting mode, the BTA30 can send signals to two Bluetooth headsets at once.

· 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.


With the BTA30, you can easily create a comprehensive home Bluetooth system. The BTA30 utilizes an external gain antenna for Bluetooth connections resulting in faster connection speeds, more stable signals, and for longer distance transmission across rooms – up to 30 meters under normal conditions.
