The FiiO BTA30 transceiver can also be used as a DAC. Of the wireless connections, the BTA30 supports Bluetooth data transmission using all modern codecs: SBC, AAC, aptX, aptX HD and LDAC. Moreover, the transceiver can both receive signals via Bluetooth and transmit them.
The new product has an AK4490 chip, via a coaxial interface the device is ready to digest signals in 24 bit / 192 kHz and DSD64 both at the input and output, by optics – 24 bit / 96 kHz in both directions. The device is only ready to receive sound via USB – albeit in 16 bit / 48 kHz format. There is also a line-out. However, the built-in DSP is capable of upsampling the signal up to 192 kHz.
There are three buttons on the front panel of the device: turning on, connecting via Bluetooth and selecting the operating mode – receiver, transmitter or DAC. The LED indicator shows which signal format the transceiver is currently working with.
On the right is the large volume control that FiiO prides itself on: the company says it is the first desktop Bluetooth device with a professional volume control. The regulator is said to work accurately and without imbalance due to the reconstruction of the ADC curve, and is also able to quickly adjust the volume of both analog and digital signals – including through the application. In the application, you can set a fixed volume level. In this case, you cannot adjust the volume when transmitting a signal via USB.
The small device in a black aluminum case weighs just 115g and is powered by USB-C. FiiO representatives spoke about the development of BTA30 back in March, but the device entered the market only now – its cost in the official store of the brand on Aliexpress was $90.
