FiiO BTR5 Lossless Bluetooth Audio Receiver 2.5MM Balanced Portable Headphone Amplifier USB DAC

FiiO BTR5 Lossless Bluetooth Audio Receiver 2.5MM Balanced Portable Headphone Amplifier USB DAC

Features:
- Flagship portable HiFi Bluetooth decoding amp: high-performance DAC ES9218Px2. Flagship decoder chip CSR8675. FPGA clock management, independent dual crystal oscillator. Bluetooth 5.0, high-definition format Bluetooth support. USB Audio decoding, 384k/DSD256 hard decoding. 3.5+2.5mm headphone dual output
- Full-format, high-standard wireless experience: Your Bluetooth device can form a Hi-Res Wireless-level audio system at any time. BTR5 supports Bluetooth 5.0 version, and supports all mainstream Bluetooth formats including for AAC/SBC/aptX/aptX low latency/aptX HD/LDAC. Bluetooth decoding sampling rate up to 96kHz
- Flagship decoder chip CSR8675: The low-power Bluetooth chip CSR8675 for enhanced audio applications supports 24bit audio processing and 120MHz DSP, which can effectively integrate various lossless Bluetooth decoding operations. Whether you are playing games, watching videos or listening to music, you can enjoy its excellent sound quality
- Fully tap the potential of DAC: ES9218P is set in Sync-synchronization mode by virtue of an accurate clock management system; the performance is completely released, and the sound reproduction is more accurate. With hardware high and low gain + digital double volume adjustment, it fully preserves the audio dynamics for music and flexibly adapts to more headphones. Under balanced output, two DACs are driven together, the power reaches 240mW under 32Ω, and the driving amplitude under 300Ω is 10Vpp
- FPGA precise clock management: The FPGA chip that is often used in mid-to-high-end HiFi players is used, and is responsible for the transmission and reception of Bluetooth and USB digital audio signals and clock management. After the Bluetooth signal is processed, the jitter is greatly reduced and the stability is significantly improved. At the same time, the problem of the clock homology between the audio modules is completely solved. (In the actual test, the Bluetooth audio index under the encoding for LDAC has reached the local playback level of high-end players)
- Independent dual crystal oscillator, accurate audio signal restoration: Thanks to FPGA, the 45.1584M/49.152M dual crystal oscillator design is used in Bluetooth decoding and USB decoding systems, which can more accurately restore audio signals of different sampling rates, enabling BTR5 to stand out among portable Bluetooth headphone amps
- USB decoding: In addition to Bluetooth decoding support lossless, USB decoding is also very good. It adopts an independent control chip for Xmos XUF208, which can realize UAC2.0 asynchronous audio stream receiving and decoding. When used as USB DAC through Type C interface, it supports 384k sampling rate and DSD hard decoding
- True flagship, true balance: In order to get greater power and resolution, BTR5 has two drive modes: balance + single-ended. Under the true balanced architecture of the balanced drive circuit, two independent DACs and amplifiers are carefully designed to decode and drive the left and right channels, which can bring you a purer sound. *In order to ensure the normal operation of the machine, when 3.5 and 2.5 are inserted at the same time, only 3.5mm has output
- OLED display: 0.49" 64x32 resolution OLED display is used to visually display information such as pairing/connection/call/power/encoding format/volume. Through the display, you can also call the setting menu, view and change the charging, car Mode, filter, EQ, etc. status
- Fashionable appearance: The popular aluminum alloy technology of mobile phones is used, the front and rear screen cover plates are made of hyperboloid glass, and the surface has an oleophobic layer anti-fingerprint treatment, and the touch feels smooth as silk. High-brightness ink black and smooth touch make the whole machine small and smart
- Built-in battery: The built-in battery capacity is 550mAh, and the full charge time is only 1.5 hours, and the full power can make the BTR5 work continuously for 9 hours (3.5mm output, tested under AAC transmission protocol)
- 2 microphones, cVc8.0 call noise reduction: built-in omnidirectional high-sensitivity microphone, compatible with 3.5mm CTIA standard headset microphone, can automatically switch the microphone channel according to the type of headset inserted, without manual switching. Both microphone channels support the eighth-generation cVc noise reduction algorithm, which automatically adjusts the microphone gain and effectively suppresses background noise (when the OMTP standard headset is inserted, only the output is guaranteed to be normal, and it does not support wire-controlled microphones and wire-controlled operations)
- When your mobile phone is connected to BTR5, the mobile phone volume and BTR5 volume can be controlled separately, and the volume levels can be subdivided through independent adjustment to obtain more accurate volume adjustment. The volume status can be remembered for you after the first use of the adjustment, and there is no need to repeat the adjustment when switching the working status. (Pair the connected device for IOS, display the BTR5 battery level in the widget)
- When your earphone is plugged in, it can detect the type of earphone inserted and automatically set the output mode. When the headset is unplugged, it automatically pauses and enters low power consumption. When the CTIA wire-controlled headset is inserted, it not only supports the wire-controlled microphone, but also supports the operation of the wire-controller, play/pause, volume and song selection
- Built-in NFC function, it can be adapted to compatible NFC devices through short-range wireless communication, eliminating the cumbersome pairing process
- A variety of operations are condensed in one button: the multi-function button has the functions of reconnecting/playing/pausing/incoming call connection/hanging up/cancelling the call/forced pairing/opening the voice assistant. After disconnecting Bluetooth, short press the multi-function button to perform the connection back operation; when the mobile phone is connected, double-click the multi-function button to wake up your voice assistant
- Download FiiO controller APP to remotely control the BTR5 and experience a more powerful flagship (EQ function does not take effect in the mode for LDAC)
- Charging switch option, when connecting the mobile phone as a USB decoder, you can choose to turn off the charging to avoid reverse charging of the mobile phone. Car mode option, when used in car, it can automatically turn on and off according to the start and stop of your car
- With professional adjustments such as left and right channel balance, eight audio filter switching, 10-band EQ, etc., to meet various personal customization needs. Specially designed odd and even sub-harmonic adjustment function can deepen the rendering effect of warm and cool colors (according to personal hearing ability, the effect presented by the above settings will be changed)
- Streamlined keys, easy to achieve complex functions
