FiiO BTR5 Bluetooth Amplifier (FIO-BTR5-B)

Equipped with two ESS Technology DAC + amplifier integrated chips "ES9818P" in a left and right independent configuration, it combines low noise, low distortion and high output. ・Equipped with FPGA for unparalleled accuracy in audio signal processing and highly precise clock management. Equipped with two independent crystal oscillators to ensure a low-jitter environment. Equipped with a 3.5mm single-ended output and a 2.5mm balanced output. Compatible with major high-quality wireless audio codecs such as AAC/aptX/aptX HD/LDAC. The Bluetooth receiver uses Qualcomm's "CSR8675" for high connection stability. The USB DAC function uses an XMOS USB controller IC and supports PCM up to 32-bit/384kHz, as well as native DSD playback up to DSD256. Equipped with an organic EL display, it has various functions that make it easier and more convenient to use with smartphones. 1.5 hours of charging allows for 9 hours of continuous playback. Main specifications Bluetooth version: Bluetooth 5.0 Volume control: Volume can be adjusted independently of the smartphone volume control Supported Bluetooth audio codecs: SBC, AAC, aptX, aptX Low Latency, aptX HD, LDAC Bluetooth chip CSR8675 DAC chip ES9218P x2 USB DAC XMOS XUF208 Dedicated pairing/play button Dedicated volume control button Transmission distance: 10m Display screen available Display contents 1.
