Flagship dual DACs For excellent sound
The KA5 features dual Cirrus Logic CS43198 DACs, known for their efficiency and their ability to sound good with a wide variety of music, to give you a serious upgrade to your sound.
High-Res decoding Listening to the heart of music
The KA5 supports up to 32bit/768kHz PCM and DSD256 decoding, allowing you to really dig into and listen to the heart of your music, no matter what device you may have it connected to.
Serious components Serious power
For better audio performance, the KA5 utilizes a 6-layer immersion-gold PCB as well as high-performance ultra-low noise op amps for powerful, robust sound.
Bold ruggedness Highly capable
The aggressive lines of the KA5 give it a bold look, while the carefully designed texture makes it a joy to handle. The dual outputs on the right side of the KA5 hint at its powerful capabilities.
*3.5mm output supports SPDIF output. After enabling the SPDIF output in the settings menu, the USB audio signals can be converted to SPDIF signals. Connect the KA5 to a higher-end external decoder to set up a better audio system.
Flexible local operating system
The OLED display and physical buttons make navigating the settings menu and looking at the playback display more straightforward and intuitive. In addition, the KA5’s built-in MCU processor handles complex operations with ease, further making the KA5 a joy to use.
*Volume buttons A/B mode
- A mode:
Volume button: short press once to increase volume 1 level, long press for 2 seconds to play previous track, and press to go page up in settings menu.
Volume– button acts in the opposite way. - B mode:
Volume button: short press once to play previous track, long press to increase volume, and press to go page up in settings menu.
Volume– button acts in the opposite way.
Companion App To better serve your needs
Besides the local KA5 operating system, you can use the FiiO Control App to take control over the KA5. Use either method to conveniently dial in the KA5 exactly how you want it.
*The KA5 can only be controlled through the FiiO Control app on an Android device.
Small in size But large in functionality
Despite the KA5’s compact size, it packs a ton of functionality – such as high and low gain, 5 selectable filters, L/R channel balance, and screen flip. Let the KA5 redefine what a tiny audio dongle can do for you.
