FIIO AND JADE AUDIO HAVE COLLABORATED AGAIN TO INTRODUCE THE ALL-NEW KA1.
FiiO has collaborated with its sub-brand Jade Audio to offer you the all-new KA1, a portable Amp & DAC. FiiO KA1 packs a punch, with a feature-rich design embedding the ESS ES9281AC PRO DAC chip, supporting 32bit/384khz PCM and DSD256 decoding. It supports MQA rendering allowing you to play master-quality authenticated files without any difficulties. The FiiO KA1 is also equipped with RGB indicator lights that are attractive but at the same time can also indicate the sampling rate of the currently playing song, helping to tell audio formats conveniently.

EMBEDDED WITH ESS SABRE PRO DAC CHIP, MAKING THE FiiO KA1 AN ALL-ROUNDER.
The FiiO KA1 is embedded with an ESS ES9281AC PRO DAC chip that combines the capabilities of a USB audio interface, DAC, and an amplifier into one device. When combined with the multi-layered HDI gold-plated PCB, the DAC results in lower distortions, higher efficiency, and lower power consumption, leading to a high-quality sound. The ES9281AC PRO DAC chip supports 32bit/384kHz PCM and DSD256 formats. You can access the DoP mode, which supports DSD 128, and the Native supports DSD256 playback. The FiiO allows you to hear even the minutest detail within your music and have an energetic listening experience.



OFFERING YOU AN ENGAGING LISTENING EXPERIENCE WITH AMPLE AMPLIFICATION, SIGNATURE TUNING, AND MQA SUPPORT
FiiO has carefully tuned the KA1 by a team of acoustic engineers to present a smooth and accurate sound. The KA1 also has a premium audio amplification circuit that delivers ample power to the connected earphones to bring the best out of them. FiiO KA1 is also certified by MQA as it can render MQA files without any distortion. MQA rendering technology can connect to an MQA Core signal like TIDAL or FiiO Music App and complete the final stage of unfolding an MQA file. The FiiO offers you a highly engaging experience with a detailed and immersive sound.

ROBUST BUILD WITH AN ALL-METAL BUILD WITH RGB LIGHT INDICATOR MAKING IT AESTHETICALLY PLEASING
FiiO KA1 is built with premium quality materials with an all-metal body making it sturdy and sleek, making it easy to use. The FiiO KA1 is equipped with an RGB indicator light in a metal body with four colors; blue, yellow, green, and magenta, making the portable Amp & DAC more aesthetically pleasing. More importantly, the RGB light can also indicate the sampling rate of the currently playing song, in turn helping you to tell audio formats effortlessly. The connecting cable is also made with premium materials and utilizes a silver-plated monocrystalline copper cable for flawless audio transmission.



EXPERTLY ENGINEERED TO OFFER UNIVERSAL COMPATIBILITY IN AN EASY PLUG AND PLAY DESIGN
FiiO KA1 provides multi-platform compatibility, making it compatible with Android/ Windows/ Mac. All you need to do is, connect the FiiO KA1 to your smartphone, tablet, desktop PC/laptop, or even portable players for high-resolution audio capabilities whenever you want. The KA1 is available in type C variant so, you can choose the one compatible with your device. The FiiO KA1 allows you to enjoy your music on whichever device you prefer.

3. If it is connected through the Type-C port, just use the Type-C edition of the KA1. If it is connected to a USB-A port, just use the USB-A to Type-C adapter to complete the connection.
4. Settings of the music app: choose the FiiO KA1/FiiO K series as the audio output device->put on headphones to enjoy music. For some computers, it is required to select the KA1 as the system audio output.
(Note: Since Microsoft has stopped driver authentication of systems below Windows10, the KA1 will not support Windows10 or below computers.)
【Mac】
1. The FiiO KA1 runs driver-free on macOS.
2. When connecting to the Type-C port on the computer, just use the Type-C edition of the KA1. If it is connected to a USB-A port, just use the USB-A to Type-C adapter to complete the connection.
3. Select the FiiO KA1 as the audio output device of the computer.
2. Since different smartphones vary in USB phone call permissions, the in-line control and phone call functions of the KA1 are temporally unavailable.
3. An incoming call will be passed out through the speaker and microphone of the mobile phone. So you can pick up the phone to answer the call without unplugging the KA1.
2. To play DSD files on the computer, please use the software which supports DSD files (such as the Foobar 2000) and install the corresponding plug-in with correct settings.
3. Switch tracks of different sampling rates may cause obvious impulsing sound. This is a normal phenomenon. So it is recommended to classify music files.
