Over the years, FiiO have launched the K5 Pro, K7, K9, and K9 Pro series of amplifiers at various price points. The K series of amplifiers have sold well around the world. As they have users’ changing and increasingly growing desktop HiFi usage needs. Thanks to continuous research and progress FiiO have a new understanding of entry-level amplifiers. The K11 will feature lots of connectors, large power output, and a slim build. The beautiful screen is a display of its prowess as your desktop HiFi companion.
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.
*USB connection to phones for decoding does not consume the phone’s battery
*Coaxial input and output share the same physical connector; Coaxial output can only be used in USB mode
1400mW large power output Capably pushing headphones
Under a 32Ω 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 | 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 Specially designed 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 aluminium 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.
*Durable LCD screen, always on with no burn-in
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.
* Brightness, colour, and light patterns all adjustable using the knobs state
One knob | One source of total control
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/PO* modes by double-pressing the knob, making it easier for you to appropriately connect to different headphones or audio setups.
*LO/PO modes remember the last volume set in each mode independently, no need to readjust the volume when switching between modes
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.
*Installing the driver unlocks support for higher sampling rates
