The new Fiio K19 features an ultra-high performance USB DAC and headphone amplifier has been designed to revolutionize your listening experience. Enjoy audio at its finest thanks to an industry-leading ESS 9038PRO flagship dual DAC combination, paired with our most powerful THX AAA amplifiers to faithfully reproduce your music. All of this joins a new DSP section, allowing for more audio customization and configurability than ever.

Equipped with USB-C, optical, coaxial, Bluetooth, and for the first time, HDMI digital inputs; RCA and 3-pin XLR balanced analog line level outputs; and three headphone jacks (1/4" single-ended, 4.4mm balanced, and 4-pin XLR balanced), the K19 is designed to elevate your audio experience no matter what audio source you're using with your headphones and speakers. Five switchable gain levels are available, enabling you to use the built-in amplifier at comfortable volume levels with your entire collection of headphones and earphones.

The K19 features DEL (Dual Engine Limiter) technology, and through proprietary algorithms, it can apply various audio effects such as dynamic range compression (DRC) and dynamic range enhancement (DRE), as well as an advanced limiter to prevent clipping.

Also on the K19 is an adjustable 31-band high-precision lossless PEQ*, which supports direct adjustment of PCM 44.1k~192k audio signals without resorting to sampling rate conversion (SRC). For each band, the gain can be adjusted between a range of +12~-24dB and the Q value can be adjusted between a range of 0.4dB~128dB.

And the equalizer curves don’t have to be used only by you — PEQ presets on the K19 can be shared between users. Being able to import and export PEQ presets opens up a whole new dimension to sound adjustment. *PEQ adjustment is supported on Windows and Mac computers, as well as with the FiiO Control smartphone app.
