We have digital input via coaxial, optical, and USB input modes, and we have outputs via 4.4mm balanced, 6.35mm single-ended, and RCA analog line-out options. K11 easily meet your need and requirements for a capable audio setup at a pocket-friendly price tag.
FiiO K11 USB DAC/AMP supports worry-free USB connection with a variety of devices. It can run without any driver installation. The K11 supports a variety of devices including PCs, Laptops, Smartphones, Tablets, and even gaming consoles(PS5, Nintendo Switch, etc.).
High-Power Amplification Section With Three-Level Gain
FiiO K11 is a highly capable USB DAC/AMP. The device is equipped with a powerful headphone amplifier section with three-level gain modes that produce a strong output delivering up to 1400mW of clear output at 32Ω of impedance load through the balanced connection output. It can easily drive most headphones and in-ear monitors with ease.
Low-Noise Power Supply
FiiO K11 is designed with a specially-developed low-noise power supply section. Using more than 16 low-noise LDOs for precise voltage stabilization and an external 12V power supply, the K11 achieves robust performance with stable power delivery to all sections of the audio circuitry.
FiiO K11 is equipped with a high-controast durable VA display screen. It displays the active sampling rate, volume level, gain level, and activate output mode.
Adjustable RGB Logo
FiiO Logo on the top of the K11 DAC/AMP has an RGB Illuminated design. It glows in different colours based on the active file bitrate. Its brightness, colour, and light patterns are all adjustable using the multi-function knob.
Multi-Function Knob Control
FiiO K11 has a minimalistic design with a multi-function knob. This knob can act as a power on/off button, volume adjustment, menu exploring, screen control, etc. Users can also switch between the Line-out and Phone-out modes by simply double-pressing the knob.
