FiiO BTR15 Bluetooth DAC & Headphone Amplifier

FiiO BTR15 Bluetooth DAC & Headphone AmplifierDue to BTR15's ability to work as a Bluetooth receiver and as a USB DAC, we have implemented a PC BT PHONE mode button on it. With just a click of a button, you can quickly switch between the three different modes to match your current scenario for listening to high quality music. BTR15 features a global parametric equalizer(PEQ). Through FIIO's self developed PEQ algorithm and user interface, in any mode* you can choose the the exact frequencies to

Due to BTR15's ability to work as a Bluetooth receiver and as a USB DAC, we have implemented a PC/BT/PHONE mode button on it. With just a click of a button, you can quickly switch between the three different modes to match your current scenario for listening to high-quality music.

BTR15 features a global parametric equalizer(PEQ). Through FIIO's self-developed PEQ algorithm and user interface, in any mode* you can choose the the exact frequencies to be adjusted along with their gain levels and bandwidth-allowing you to fine-tune the sound to exactly the way you want it.

PEQ notes:
*BT mode PEQ adjustments are implemented through the QCC5125 DSP with support for LDAC and other Bluetooth formats up to 96kHz/24bit.
*PC/PHONE mode PEQ adjustments are implemented through the XMOS XU316 with support up to PCM 192kHz.
*PC/PHONE mode PEQ adjustments are implemented through the XMOS chip. Enabling or disabling the PEQ, USB will restart and disconnect.

BTR15 supports MQA Full Decoder*, which means the MQA decoding can be achieved in any music app. This allows for high-resolution, master-level sound quality in reasonably sized files well-suited for your mobile device.
*Supports up to 384kHz sampling rate
