Manufacture Description
Audiophile-approved performance Flagship Bluetooth chip CSR8675
The Qualcomm CSR8675 is a low-power Bluetooth chip with enhanced audio capabilities, such as supporting 24-bit audio processing and possessing a 120Mhz DSP, allowing it to powerfully handle various Bluetooth decoding functions with ease. Whether you are watching videos, playing games, or listening to music, thanks to this Bluetooth chip you can enjoy remarkable sound quality.
Handling it all with ease FPGA precision clock management
An FPGA, often used in high-end music players, is not only responsible for the transmission and reception of Bluetooth and USB digital audio signals, but also for clock management. In the BTR5, after the Bluetooth signal is processed the FPGA greatly reduces jitter and improves signal stability, completely solving the problem of different clock rates that exist between the different parts of the audio architecture.
Fully equipped to tackle USB decoding With generous power worthy of a flagship
In addition to its considerable lossless Bluetooth format support, the BTR5 is also quite the capable unit when it comes to USB decoding. Utilizing an independent XMOS XUF208 control chip, the BTR5 is capable of asynchronous audio decoding under USB Audio Class 2.0. And when connected as a USB DAC through its USB Type-C connector, the BTR5 can decode up to 384kHz sampling rate and native DSD.
One not enough? Try adding another one DAC utilized to its full potential
With its precise clock management system and being set to synchronous mode, we fully unleash the potential of the ESS SABRE ES9218P for extremely detailed reproduction of sound. The multi-level analog gain and digital volume are combined into a singular dual-volume adjustment design, allowing you to more precisely adjust the volume while fully preserving the dynamic range in your music. Under balanced output with 2 DACs working in conjunction, the BTR5 is capable of 220mW output at 32Ω and 7.6Vpp at 300Ω.
Independent dual crystal oscillators for accurate audio reproduction
With the addition of a dedicated FPGA, the 45.1584/49.152 MHz dual crystal oscillators during Bluetooth and USB decoding can more accurately reproduce audio signals under various sampling rates, giving the BTR5 exceptional audio fidelity among Bluetooth amplifiers.
Balance befitting of a flagship
For greater power and detailed resolution, the BTR5 features both balanced and single-ended outputs. In its truly balanced audio architecture, each channel is driven separately from the other with its own DAC and amplifier, allowing the BTR5 to bring you a purer sound with unmatched finesse and balance.
iOS/Android Application
BTR5 offers the companion iOS/Android remote control application. The setting is saved on BTR5,once configure by the app. BTR5 restores the setting after power on.
Displaying its beauty for all Smartphone-based OLED technology
The one display that shows all – a major feature of the BTR5 is the crisp 0.49 inch 64x32 resolution OLED screen that displays pairing/connection/call status/power status/encoding format/volume. And with the display, you can call up a menu that allows you to visually view and adjust the charging status, enable car mode, change filters and EQ, etc.
10-Band Equalizer
BTR5 supports the built-in 10-Band Equalizer. You can control the EQ using the FiiO Music APP . Once configured, BTR5 runs the EQ processing without the app, for every audio sources over Bluetooth *EQ is invalid under BTR5's LDAC
