FiiO BTR5 2021 Headphone Amplifier

FiiO BTR5 2021 Headphone Amplifier:

High-performance Dual DAC chipset(Dual ES9218C)

FiiO BTR5 2021 is with an advanced Dual ES9218C DAC chipset, paired to a flagship-grade XMOS XU208 USB transmitter ensuring support for high-resolution 32-Bit/384kHz and DSD256 native support(USB connection).

MQA Decoding

FiiO BTR5 2021 supports for MQA Render, allowing for high-resolution, high-quality sound in reasonably sized files well-suited for your mobile device.

Qualcomm CSR8675 Bluetooth Chip

The Qualcomm CSR8675 is a low-power Bluetooth chip with enhanced audio capabilities, such as supporting 24-bit audio processing and possessing a 120 MHz DSP, allowing it to powerfully handle various Bluetooth decoding functions with ease.

Bluetooth V5.0 with Full Hi-res Codec Support

The Bluetooth device can be transformed into a part of a Hi-Res Wireless setup by simply connecting it to the BTR5 2021. With the help of the BTR5 2021's Bluetooth version 5.0 supporting high-resolution formats such as AAC/SBC/aptX/aptX Low Latency/aptX HD/LDAC up to 96kHz, you can get a totally portable yet excellent sounding setup with your current device!

FPGA Clock Management

An FPGA is responsible for the transmission and reception of Bluetooth and USB digital audio signals, as well as clock management. In the BTR5 2021, after the Bluetooth signal is processed through the FPGA, jitter is greatly reduced and signal stability is improved, completely solving the problem
of different clock rates that exist between the different parts of the audio architecture.

XMOS XUF208 USB Decoding 

In order to further improve sound quality, the FiiO BTR5 2021 utilizes the XMOS XUF208 USB decoding chip paired with a precise clock matching management system, allowing for support up to 384kHz/32 bit PCM and hardware-decoded native DSD - so you can be sure of excellent sound no matter what format your music is in.

Two-Level Gain

FiiO BTR5 2021 has a two-level gain switch that users can use to adjust the output for high and low-sensitivity IEMs/headphones. High-gain mode increases the current in the amplification circuit resulting in better power for high-impedance headphones.
