FiiO Slim Desktop USB DAC and Headphone Amplifier with 3 Gain Levels and 3 Volume Curves (Black)

Over the years, FiiO has launched the K5 Pro, K7, K9, and K9 Pro series of amplifiers at various price points. K series of amplifiers have sold well around the world. Thanks to continuous research and progress. FiiO has a new understanding of entry-level amplifiers. The FiiO Slim Desktop USB DAC and Headphone Amplifier feature lots of connectors, large power output, and a slim build.

A Variety of Inputs and Outputs Ready for You

On the K11 are USB, optical and coaxial inputs as well as 4.4mm, 6.35mm, RCA line-out, and coaxial outputs. Having more inputs and outputs than other typical entry- level amps means the K11 is more than capable of meeting your needs of putting together a capable audio setup.

1400mW Large Power Output Capably Pushing

Under a 320 load, the K11 is capable of pushing 1400mW under balance modes. This allows it to easily drive many Hifi earphones and headphones to fully unlock their potential.

3 Gain Levels and 3 Volume Curves

The K11 has 3 separate gain levels, each gain level having its own volume curve. This allows the K11 to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder to drive over-ear headphones.

Specially-Designed Audio Circuit and Power Supply

Within the K11's slim build lies a specially-designed audio circuit designed for great sound quality. This is backed by more than 16 low-noise LDOS for precise voltage stabilization and powered by an external 12V switching power supply. All of this leads to a purer and more robust supply of power, leading to stable high- quality audio and thus truly enjoyable music all of the time.

Slim on One Side Stable on the Other

The slim aluminum alloy body allows you to easily place the K11 anywhere, making it easier to put the device in a way that complements the rest of your desk. Thanks to the silicone anti-slip pad, the K11 rests stably and firmly on your table too.

A Beautiful Screen Full Of Clarity

A custom, high-contrast and durable LCD screen allows you to easily see the sampling rate, volume, gain, or output mode with just a glance.

Adjustable RGB Logo Lighting

The FIIO logo is illuminated with RGB lighting, giving you a quick way to identify the sampling rate of the current audio being played back. Six LED strips work in conjunction with a carefully placed reflective film and parts of the body designed to reflect light to make the light show uniform and elegant.

One Knob and One Source of Total

In the K11's minimalist design, the volume knob acts as a crucial source of total control. The K11's multi-function volume knob is used to power the device on and off, for menu operation, for volume adjustment, and for other functions. The knob is designed so that you can quickly execute various complex actions by simply pressing and turning the knob. You can also quickly switch between LO and PO modes by double- pressing the knob, making it easier for you to appropriately connect to different headphones or audio setups.

Driver-Free Mode, Worry-Free Operation

The K11 used in USB DAC mode does not require a driver on Windows 10 and above systems, and can also be used with video game consoles such as the PS5 and the Switch. Simply plug and play for worry- free usage whether you are enjoying music or being immersed in games.
