Qualcomm Flagship QCC5181 Chipset with Bluetooth 6.0 & aptX Lossless
Equipped with Qualcomm’s premium QCC5181 Bluetooth chipset, supporting LE Audio and up to 2.1Mbps bandwidth for true CD-grade lossless audio via aptX Lossless in the aptX Adaptive suite. With Bluetooth 6.0, enjoy lower latency, lower power consumption, stronger anti-interference, and a more stable long-distance wireless connection.
Upgrade Your Speakers/Amplifier to aptX Lossless & LDAC Wireless Audio
Transform your existing speaker or amplifier system into a high-resolution wireless audio setup. Fully supports LC3, aptX Lossless, LDAC, SBC, AAC, aptX, aptX HD, and aptX Adaptive—bringing stunning clarity for movies, gaming, and music.
Fully Balanced Complementary 24-Bit R2R DAC for Pure Analog Warmth
Features FiiO’s self-developed four-channel fully balanced complementary 24-bit R2R resistor array DAC. Built with 192 pieces of 0.1% precision, 30ppm thin-film resistors. Compared with non-complementary R2R structures, this architecture offers lower noise, fewer harmonic artifacts, and a darker background for rich, musical, analog-like sound.
Multi-Input Decoding: Bluetooth / USB / Optical / Coaxial
Supports Bluetooth, USB, and SPDIF (optical & coaxial) inputs—making it highly versatile and compatible with smartphones, computers, CD players, TVs, and DVD players. One device covers all scenarios when building your wireless HiFi audio system.
Extensive Output Options with RCA, XLR, Optical & Coaxial
Comes with dual RCA and one XLR analog line-out, plus optical and coaxial digital outputs. Easily integrates with powered speakers, amplifiers, DACs, or other audio components—ensuring flexible system matching for any setup.
Bonus Feature: Convenient Knob Controls + Remote + App Support
Dual physical knobs with a built-in display for easy desktop adjustments. Includes an IR remote and supports the FIIO Control App for effortless long-distance operation.
