FIIO BTR15 Serial Number Bluetooth Receiver Bluetooth USB DAC aptX LL Adaptive HD LDAC Codec Wireless [J

Equipped with two ESS Technology DAC + amplifier integrated chips ES9219MQ in left and right independent configuration. Achieving both low noise, low distortion, and high output: The BTR15 uses ESS Technology's integrated DAC chip ES9219MQ , with a total of two independent left and right DAC chips. The maximum power during balanced output is improved by approximately 40% compared to the previous model (240mW → 340mW), providing powerful drive power while independently supplying power to the DAC section of the integrated DAC chip and the headphone amplifier section. The design combines low noise and low distortion. 384kHz/32bit, DSD256, MQA full decoding playback possible with XMOS XU316 with powerful processing power: BTR15 uses XMOS USB controller chip XU316 and supports PCM384kHz/32bit in input from USB type C terminal. Supports 32bit, DSD256 (Native) playback. In addition, the powerful computing power of 16 cores enables full MQA decoding. *The USB DAC function supports two modes: USB Audio Class 1.0 mode, which does not require a driver, and 2.0 mode, which allows full spec playback. In the latter case, you will need to download and install the driver from the FIIO official website. Qualcomm's QCC5125 is used as the Bluetooth receiver to achieve high connection stability: Equipped with Qualcomm's Bluetooth IC QCC5125 installed in BTR15, AAC/SBC/aptx/aptx LL/aptx Adaptive/aptX HD It supports a wide range of audio codecs such as /LDAC. In addition to the 3.5mm single-ended output, it also has a fully balanced 4.4mm balanced output: In addition to the standard 3.5mm single-ended output, the BTR15 also has a balanced output with a 4.4mm terminal. With a fully balanced audio architecture that allows the ES9219MQ to operate left and right independently, each channel is driven by an independent DAC and amplification stage, boasting a maximum output of 340mW. Global parametric equalizer function that allows appropriate equalization regardless of the mode of use: The BTR15 is equipped with a Global Parametric Equalizer (PEQ) that is uniquely developed by FIIO and allows accurate equalization settings in both wireless and wired modes. Equipped with Function . PEQ adjustment in Bluetooth mode uses QCC5125's DSP, and when used as a USB DAC, it is processed by XMOS XU316, but FIIO's unique interface allows common PEQ settings to be used in any mode. *If you enable/disable PEQ when using it as a USB DAC, the USB connection will be reset. Please adjust the volume and playback operations on your smartphone again. Equipped with a 0.96 inch organic EL on the front panel of the main unit. Easily check operating status and settings: The front of the BTR15 is equipped with a 0.96-inch, clear OLED display with a resolution of 96 x 96 pixels. The display is larger than the BTR5's 0.49 inch for improved visibility and can display pairing destination, connection status, call status, power status, encoding format, and volume. In addition, you can use
