Features Two ESS ES9069Q DAC For Accurate Decoding & Clean Sound

The BTR17 houses two DAC chips from ESS - the ES9069Q is based on the fourth-generation 32-bit HyperStream architecture for an excellent performance of the device while using less power. This configuration delivers a dynamic range of up to 130dB and -130dB total harmonic distortion for refined and coherent audio.

Features THX AAA 78+ Headphone Amp With Powerful Sound Output

FiiO BTR17 equips the THX AAA 78+ headphone amp as of the FiiO KA17 and M23 with a fully balanced four channel with 8 op-amps configured parallel. This results in clean and natural sound with controlled power and robustness. When the power in port is connected to USB power and desktop mode is activated, the BTR17’s THX headphone amp uses four op-amps in parallel for current amplification for high performance. It offers output power of 650mW+650mW with an increase of 203% for excellent performance.

Multi-Stage Audio Circuit With Hi-End Components For Premium Audio

FiiO BTR17 equips the multi-stage HiFi audio circuit that processes the signal within its compact body. It features dual clock digital audio and a high-quality DAC to process the digital signals while the LPF preamplification and multi-stage analog audio process deliver the audio with excellent transient response and high accuracy.

Equips Flagship XMOS 16-Core XU316 For Hi-Res Decoding With Dual Headphone Output

FiiO BTR17 features XMOS 16-Core XU316 embedded in the USB chip, which enhances data transmission with low latency. It allows the DAC to decode any audio stream as it supports 768kHz/32bit audio, DSD512 native, MQA full decoding, and PEQ 192kHz for a high-definition music listening journey. BTR17 is embedded with dual headphone outputs of single-ended 3.5mm and balanced 4.4mm, supporting CTIA protocol in-line controls.

Patented Desktop Mode With Type-C Interface For Independent Power Supply

FiiO BTR17 has a dedicated desktop mode that allows you to connect to a phone as a dongle DAC and headphone amplifier. The BTR17 is equipped with a Type-C port that enables you to connect an external power supply. This helps the battery to fully charge itself without getting overcharged and without discharging the built-in battery and phone battery while delivering high-quality audio. 

Enjoy Lossless Audio With Flagship Qualcomm Bluetooth Chip QCC5181.

The BTR17 provides CD-level lossless audio with precise detailing through the Qualcomm Bluetooth chip QCC5181. It offers Bluetooth LE audio standards with transmission bandwidth capacity of 2.1Mbps and lossless audio within the aptX Adaptive system. BTR17 features Bluetooth 5.4 supporting LDAC and aptX Adaptive 96kHz/24bit. When this configuration is combined with Snapdragon sound technology, it delivers an immersive music-listening experience.

Choose Between Three Operating Modes With a Three-Position Switch

PHONE(phone dongle): The device's internal battery participates in the power supply, reducing the power consumed by the connected phone.

Listen To Your Music As You Like With The Ten-Band PEQ Adjustment Feature

The FiiO engineers have put their heart and soul into integrating the software and hardware components to create user-friendly apps and web interfaces. The BTR17 features proprietary PEQ adjustment algorithms that allow you to tune the EQ frequency points, gain, bandwidth and Q value to customise or correct the frequency response curve of various headphones. You can also import, export, share, and save EQ curves for everyone to enjoy the tuning experience. NOTE: On the side of the device features a dedicated EQ shortcut key that allows you to instantly select your desired EQ settings.

Three-Stage Power Transmission With Independent Power Supply

FiiO BTR17 follows a three-stage, three main rails precision power supply with 8 tantalum audio capacitors with 10 - 0.1% high precision thin film resistors. In the first stage, the filtering and overvoltage protection takes place. The second stage handles the DC-DC boost conversion. The third stage comprises high-precision LDO voltage stabilisation. It features an independent power supply rail for the digital signal, digital-to-analogue conversion and analogue amplification parts of the audio circuit and more than 10 small rails. This configuration offers stability with ample energy supply and excellent sound quality.
