Hardware

The FiiO K9 Pro is equipped with the latest Qualcomm QCC5124 Bluetooth processing chip, supporting formats such as LDAC, aptX HD, and aptX Adaptive. This chip ensures that Bluetooth connections are reliable and fast, satisfying both the low latency needs for games/videos and the high bit rates required for high-resolution Hi-Res Audio. Bluetooth format support: AAC, SBC, aptX, aptX LL, aptX HD, aptX Adaptive and LDAC.

Dual-Mode Timing Control

The latest generation of XMOS chips supports dual-mode timing control technology. USB and Bluetooth decoding use dual asynchronous femtosecond clocks, while optical and coaxial decoding use automatic PLL clocks. A more precise clock control system makes it easier to work with any source and maintains the highest possible quality.

Bluetooth aptX HD et LDAC

Thanks to its Bluetooth 5.0 receiver, the Fiio K9 Pro ESS headphone amplifier can also receive music streamed from a smartphone, tablet or computer. Support for SBC and AAC codecs ensures optimal compatibility with any source, while the HD aptX HD and LDAC codecs guarantee very high listening quality. Finally, the aptX Low Latency codec is also in place to avoid any lag between sound and image when you stream audio from a video.

LDO for every audio circuit level

Not only is the dedicated high-performance transformer important to shaping the FiiO K9 Pro’s phenomenal sound. Particular attention has also been paid to power stabilization and filtering in the audio circuit. Very quiet LDOs are used to regulate the voltage at each stage of the audio circuit. No expense has been spared to provide clean power, and the K9 Pro has a total of 20 LDOs on board.

Connectivity

In addition, the device features a linear power supply for cleaner power management, compatibility with the FiiO app on smartphones, three adjustable gain levels, and an adjustable volume knob with an LED backlight.
