Desktop mode | Taking it to the next level

The desktop mode has been continually refined with the release of various products, such as the portable yet desktop- grade M17, Q7, M15S, Q15 and KA13. And now the perfected desktop mode has found its way to the KA17.

The FIIO KA17 features a special desktop mode, activated using the dedicated D.Mode switch. Enable the desktop mode, and the KA17 will automatically adjust the DAC, amplifier power supply, and the amplifier power output to fully unleash their potential with greater power output.

Parallel output | Big boost in power

With sufficient USB power supply input and desktop mode enabled, the KA17’s four THX headphone amps work together in parallel for greater current and overall power output. The result is up to 270mW+270mW power output for single-ended out, and up to 650mW+650mW power output for balanced out.

Dual flagship ES9069Q DACS Two cores power four ways, Excellent performance

The KA17 employs two of the new ESS ES9069Q flagship DACS, powered by fourth-gen 32bit HyperStream technology. These chips feature even higher performance, lower power consumption, and less digital noise than previous generations for an absolutely pristine and pure audio background.

An ace up its sleeve Ten-level highly precise PEQ

The XMOS XU316 chip allowed FIIO engineers to develop a highly precise adjustable PEQ*, with 10 customizable frequency bands. FIIO’s self-developed PEQ algorithm and interface allow you to fine-tune the frequency, gain, and bandwidth of each PEQ band, letting you dial in the sound exactly the way you want it.

Outstanding performance | Audiophile-grade 16-core XMOS XU316

Handling USB duties in the KA17 is the 16-core XMOS XU316, rarely found in audio dongles. This chip features lower latency, more stable signal transmission, and better compatibility than typically used USB control chips. And when paired with dual crystal oscillators, the KA17 is more than capable of handling various digital audio sources with various sampling rates.

All-new THX AAA 78+ Headphone Amp Design | Compact and Elegant, Yet Boasting Pure and Refined Sound

The THX AAA 78 headphone amp proved itself in the mid-to-high-end M11 Pro and M11 Plus players. Now, the even newer and upgraded THX AA 78+ features in the KA17.

Inside the KA17 are THX AAA 78+ headphone amplifiers, with 8 op amps working in parallel in a 4-channel fully balanced configuration, allowing for not only greater power output, but also more detailed and realistic sound.

Comparable to DAPs | Multistage HiFi Audio Circuit

FIIO engineers were cleverly able to adapt the audio circuit designs of mid to high-end digital audio players to the compact KA17.

With its high-precision handling of digital audio signals thanks to the dual crystal oscillator clocks and high-performance DAC converted to analog signals output by a robust analog section consisting of LPF voltage amplification, BUF current expansion and headphone amps working together in parallel.

You can be sure that the KA17 can reproduce the detail and dynamics in your music as well as a serious digital audio player.

Like Yin and Yang Separate Digital and Analog Boards

The digital and analog portions of the audio circuit lie on totally separate circuit boards in the KA17, each board equipped with a shielding cover for total isolation. This ensures that the digital and analog portions of the audio circuit do not interfere with each other, enabling accurate processing of audio signals.

3-Stage 10-Rail Power Supply Design | Compact Cize Outside, Grand Design Inside

Inside the KA17 is a 3-stage 3-main rails power supply design.

The three main stages of the power supply consist of a first stage filtering + overvoltage protection, second stage DC-DC boost conversion, and a third stage LDO voltage stabilisation.

This filtering of electricity applies to each of the three main power supply rails, one each for the digital, digital- to-analog conversion, and analog signal parts of the audio circuit.

To top it all off, the power supply circuit is divided into ten smaller ralls. The power supply found in the KA17 features many of the same principles as those found in desktop headphone amplifiers, ensuring a robust foundation for the KA17’s excellent sound.
