This allows you to truly immerse yourself in the essence of your music and listen to it regardless of the device you have connected to.

Dual Outputs - Dual Amplifiers

For powerful output and serious amplification, the KA5 is equipped with two independent 8261 AMP chips. The KA5 provides up to 265mW of clean power per channel through the balanced port with a 32-ohm load. Even through the single-ended 3.5mm output, it delivers power up to 122mW with a 32-ohm load. These figures are comfortable enough to easily drive most headphones.

3.5mm, 4.4mm Headphone Outputs, and SPDIF Digital Output

The FiiO KA5 has two headphone outputs, including a single-ended 3.5mm and a balanced 4.4mm. An interesting feature is that the 3.5mm jack is combined with the SPDIF digital output.

Multifunctional Physical Buttons

FiiO has equipped the KA5 with a multifunctional button, as well as physical volume control buttons. The volume buttons also have multiple A and B functions. In A mode, a short press changes the volume, and a long press changes the track. In B mode, a short press changes the track, and a long press changes the volume. This setting can be changed using the FiiO Control App.

Supports FiiO Control App

The FiiO KA5 is fully compatible with the FiiO Control App. It allows the user to adjust various settings of the device, including digital filters, volume control settings, gain settings, OLED display settings, etc. Discover a whole new realm of KA5 settings through the app.

High-Quality Build and OLED Display

The KA5 has a compact form factor and is housed in a premium-class aluminum alloy chassis. The device has front and rear tempered glass panels that give it a first-class and exquisite finish. The aggressive lines of the KA5 give it a bold look, while the carefully crafted texture makes it pleasant to handle. The built-in OLED display shows various settings at any time during operation.

High-Quality Components

To improve the sound quality, the KA5 uses a 6-layer PCB with gold-plated traces and high-performance operational amplifiers with ultra-low noise levels, ensuring powerful and reliable sound.

Power output

This is the useful power developed by the amplifier in the load resistance. Amplifiers are usually characterized by the highest power that can be obtained at the output, provided that the distortion does not exceed the specified permissible value. This power is called the output power of the amplifier.
