Fiio BTR17 Wireless DAC

The BTR17 incorporates flagship-level features such as a multi-stage audio architecture and a precision power supply comparable to other high-end players and DAC/headphone amplifier combinations. It is a true all-rounder that will once again set a new standard among Bluetooth headphone amplifiers. 

A new chip era - lossless Bluetooth

The BTR17 is equipped with Qualcomm's new flagship Bluetooth 5.4 chip QCC5181, which not only fulfils the Bluetooth LE audio standard and has a transmission bandwidth of 2.1 Mbps, but also enables lossless quality within the aptX Adaptive system. This means that the chip is able to achieve CD-level lossless sound quality via Bluetooth audio. It also supports the Bluetooth audio codecs LDAC, aptX Adaptive and aptX Low Latency - your Bluetooth listening experience has never sounded so good. 

BTR17 has a dedicated D.Mode (desktop mode) and a connection for an external, independent power supply. If you connect the BTR17 to a phone in desktop mode as a dongle DAC and headphone amplifier, you can also connect an external power supply to the BTR17. BTR17's battery is fully powered via USB, which not only prevents overcharging and over-discharging of the built-in battery, but also enables powerful audio output without draining the battery of the connected phone. Patent number: L202321946664.8 

Fiio BTR17 features a convenient three-position PC/BT/PHONE switch to optimize power supply status according to the connected device. These are:

• PC: BTR17 is fully powered by the computer.
• BT: BTR17 is powered by the internal battery and can be used for charging and power supply when connected to USB.
• PHONE: BTR17's internal battery helps the power supply, reducing the power consumption from the connected phone. 

The flagship XMOS XU316 is used as the USB chip - The high processing power of the XU316 also enables a high-resolution PEQ that supports up to 192 kHz audio on the BTR17. 

Sound tuning - high-precision, lossless 10-band PEQ 

FIIO has constantly worked on integrating software and hardware to develop user-friendly applications and web interfaces. The continuously refined proprietary PEQ adjustment algorithms allow you to fine-tune EQ frequency points, gain, bandwidth and Q value to your liking. 

Inside the BTR17 are two ESS ES9069Q DACs based on the fourth generation 32-bit HyperStream architecture, offering high performance with lower power consumption. This architecture helps to further reduce the digital noise in the DAC, achieving a dynamic range of 130 dB and an overall distortion of -120 dB. The result is a fuller, musical sound against a clean background.

THX AAA 78+ headphone amplifier, thoroughly improved

The BTR17 utilizes the THX AAA 78+ headphone amplifier as used in the well-known FIIO KA17 and M23. The four-channel, fully balanced design with 8 operational amplifiers connected in parallel ensures robust yet controlled performance for a clearer and more natural sound. 

Miniature amplifier, power sound

When USB power is applied to the POWER IN port and desktop mode is enabled, the BTR17's THX headphone amplifier utilizes four operational amplifiers connected in parallel. The result is a balanced output power of up to 650mW+650mW, an astonishing increase of 203% compared to the BTR7. This is comparable even with desktop headphone amplifiers. 

The BTR17 integrates mid to high level hi-fi player level signal processing into its compact housing, comparable to premium digital audio players. 

Three-stage ten-rail precision power supply, limitless energy 

The first stage consists of filtering and overvoltage protection, the second stage is responsible for DC-DC step-up conversion, and the third stage consists of high-precision LDO voltage stabilization. There is an independent power supply rail for the digital signal, the digital-to-analogue conversion and the analogue amplification parts of the audio circuit as well as more than 10 small rails. This specially designed power supply ensures a stable and sufficient power supply, providing a solid foundation for excellent sound quality. 

The eye-catching, pushable volume control features a 3D design engraved on both sides. The robust 3D aluminum alloy body with a back cover made of innovative, fully welded rawhide and the two-piece front design provide a comfortable grip. The new user interface, made possible by the 1.3-inch colour IPS screen, supports both Chinese and English displays. The font colour even changes along with the audio format.
