Fiio, "super" advanced LDAC compatible Bluetooth transmission reception USB DAC -AV Watch

Emirai will launch a USB DAC with Bluetooth receivers and transmitter functions on December 2 from the FIIO ELECTRONICS brand that covers codecs such as LDAC and AptX LL.The price is open price, and the expected price is around 15,950 yen.

The successor to the "BTA30" which was highly evaluated by the media hub function of each unit.Suppose that the functions and performance have been greatly enhanced, and it has evolved into a "one and only" super "media hub" that can be used from entry users to skilled audio files.

According to Bluetooth 5.0, SBC, AAC, APTX, APTX HD, LDAC, SBC/APTX/APTX LLAPTX HD/LDAC can be used in receiving mode, and the audio system at home can be wirelessly compatible.。The optimal codec can be selected according to the content, such as a high -quality LDAC and a low -delay AptX LL, so you can build a highly flexible listening environment without restrictions on cables.LDAC can be used when inputting light/coaxial digital, USB entry.

Equipped with light/coaxial digital input and output, USB input, and RCA analog output.USB adopts Type-C, not only digital input, but also power supply terminal.When the coaxial output is used, the coaxial input cannot be used, and the "bypass mode", which performs optical input and light/Bluetooth output at the same time, can be connected from the optical input to the light output.By pass mode is only available in transmitter mode and light input in DAC mode.

The Bluetooth chip uses a Qualcomm "CSR8675" that supports 32 -bit audio processing, and is equipped with a 120MHz operation DSP, effectively integrating various Bluetooth related functions as one package.There is.An external high gain antenna is also used for Bluetooth connection, and under normal use conditions, a higher -speed connection speed and a stable signal transmission can be made in a maximum range of 30m.

If you turn on the digital decode mode, you can use it as a D/A converter or D/D converter, and you can also switch the USB Audio Class2.0 and USB Audio Class1.0 by changing the settings from the application.In addition, the app allows channel balance, switching four types of audio filters, and changing the priority of Bluetooth format.

The new XMOS receiver chip has been newly adopted, greatly improved the compatible sampling rate/bit rate, and the USB playback supports the up to 384kHz/32 -bit PCM and DSD 256.Up to 384kHz/24bit, DSD 128, and optical input are compatible with up to 96kHz/24bit, and "it has sufficient abilities as a full -fledged DAC as well as an introductory device for digital audio."。

The DAC chip is the "ES9038Q2M" made by ESS Technology, and the total high wave distortion+noise (THD+N) when the RCA output is output has been improved to 0.0008%or less, and the SN ratio has been improved to 118 dB.The independent high -performance DSP chip "CT7302" with the Bluetooth + SPDIF decoding function is also incorporated, and the digital audio signal can be uploaded to 192kHz by using a specially prepared Up Sampling DSP.The audio opi amplifier is "OPA1662".

The housing is made of aluminum alloy, and can be switched to mode and input source depending on the physical button and switch for the main unit.In Bluetooth reception mode, you can remember two devices at the same time, and you can easily select which button to connect to the Bluetooth device.However, if you use LDAC and AptX LL in Bluetooth transmission mode, you cannot connect to two Bluetooth devices at the same time.

The top plate also has a Status indicator, allowing the Bluetooth codec used in the color of the LED.The external dimensions are 120 x 55 x 25.8mm (width x depth x height) and weighs 145g.Includes USB Type-A to Type-C cable, RCA cable, rubber foot, etc.
