Innovative, 31-band high-precision lossless PEQ
The K19 features DEL (Dual Engine Limiter) technology, and through proprietary algorithms, the K19 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 PEQ 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 dimension to sound adjustment!
*PEQ adjustment is supported on Windows and Mac computers, as well as with the mobile control app
ADI ADSP-21565 with SHARC+ core
For the first time in an FIIO product, the K19 flagship desktop DAC and headphone amplifier utilizes an ADI ADSP-21565 DSP chip with the SHARC+ core backed by a custom ultra-low phase noise femtosecond crystal oscillator.This DSP chip featuring a high clock frequency of 800MHz and capable of 64-bit double precision floating point calculations is what makes the 31-band high-precision lossless PEQ possible in the K19. The ADI DSP chip not only ensures that audio signals after PEQ adjustment are of high quality and with minimal distortion, it also helps to enable powerful system protection functions that safeguard both the K19 and the other devices and headphones connected to it.
Flagship ESS 8-channel ES9039SPRO*2 DACs
Inside the K19 are two of the ESS 8-channel ES9039SPRO DAC chips, featuring the fourth generation 32Bit HyperStream architecture and capable of ultra-high dynamic range with ultra-low noise. These DAC chips allow the K19 to output clearer and richer audio with plenty of detail.
8-channel THX AAA 788+ headphone amplifier
The K19 features a headphone amplifier design consisting of an 8-channel THX AAA 788+ headphone amp architecture working together in parallel and backed by a high-voltage power supply. The THX amp chips are connected in parallel via 2x2 groups to make up a totally balanced,4-channel amplification system. The result is enhanced transients, and high-power output up to 8000mW+8000mW with a 32Ω load - allowing the K19 to drive all kinds of headphones with ease.
Separated and shielded circuit boards
The digital and analog audio circuits of the K19 lie on separate boards for full isolation and greatly reduced interference. There are metal shields for the DSP board, DAC board, and the THX head-phone amplifier board, as a result of the digital board and module board adopting a compartmentalized aluminum alloy isolation design. These measures all help to minimize crosstalk to ensure signal purity. In addition, the honeycomb-mesh aluminum alloy body can also help to further reduce external interference, allowing you to enjoy pure, clean music.
