The K19 includes a 31-band high-precision PEQ for precise audio adjustments, and its powerful amplifier section provides up to 8W per channel. The FiiO K19 is designed to be the ultimate all-in-one desktop solution for audio enthusiasts!

31-Band PEQ

The K19 incorporates DEL (Dual-Engine Limiter) technology and proprietary algorithms, granting access to various audio effects like DRC (Dynamic Range Compression) and DRE (Dynamic Range Enhancement). It features a 31-band lossless PEQ, allowing adjustments from 44.1kHz to 192kHz without impacting the sampling rate conversion (SRC). Users can fine-tune each band with a gain adjustment ranging from +12 to -24dB, enabling complete output customization.

Flagship Dual DAC Chipset

The K19 is equipped with two latest-generation 8-channel DAC chips from ESS Technologies. These ES9039SPro chips, one for each channel, utilize the fourth-generation 32-bit Hyperstream architecture. They deliver true high-resolution audio processing with an exceptionally high dynamic range and minimal distortion.

High-Power 8-Channel THX Amplifier Section

At the core of the K19 is an 8-channel THX AAA 788+ amplifier. The THX chips are connected in parallel, creating a balanced 4-channel architecture for headphones. This powerful amplifier section can output up to 8W per channel, providing ample power to drive even the most demanding headphones with plenty of headroom.

High-Resolution

The K19 features dual ACCUSILICON AS318-B femtosecond crystal oscillators known for their ultra-low phase noise. These components are carefully selected to ensure precise sound signal restoration and accurate audio reproduction across various sampling rates.

Shock-Proof Die-Cast Chassis

The K19's seamless design is crafted from die-cast aluminum alloy. The device is meticulously finished with a multi-axis CNC machining process for a premium look and feel. Its unibody construction and shock-proof internal chassis provide stability and durability.

Multiple Input Options Including HDMI/ARC

The K19 offers a variety of input options, from traditional USB and wireless Bluetooth to HDMI and ARC capabilities. It is the first DAC/AMP in FiiO's lineup to support HDMI and ARC inputs. The HDMI input supports 192kHz/24-bit audio, while HDMI ARC supports 44.1/48kHz bitrates. Additional connectivity options include USB, Optical, Coaxial, and Bluetooth.

Power Supply

The K19 is equipped with a 40W low-noise industrial-grade power supply that operates across a broad voltage range and varying temperatures. The power supply features isolated and shielded analog and digital circuits to ensure reliable performance. This industrial-grade power supply ensures clean, accurate, and efficient power delivery to the audio components.
