Brand: FiiO Manufacturer: FIIO Model: FIO-K11-B Product Model: FIO-K11-B Color: Black Included: Warranty card Quantity: 1

The K11 is the entry model of a compact desktop DAC headphone amplifier with a slim body, extensive inputs and outputs, and high output power. FIIO's K series of desktop DAC headphone amplifiers, developed over many years, has undergone continuous evolution. The latest K11 features a completely new body design and combines a fully balanced headphone amplifier circuit, delivering up to 1400mW of drive power, with uncompromising audio playback quality. It has an LCD display for intuitive operation of the unit and is a high-performance model that blends with desktop spaces.

- [Uses the Cirrus Logic DAC chip CS43198, supporting 384kHz/32bit and DSD256 playback] The K11 adopts the CS43198 DAC chip from Cirrus Logic, which features low power consumption and excellent audio characteristics. The CS43198 is a Master HiFi DAC that meets the strict standards set by the company to provide faithful recording playback. With this chip, the K11 achieves an S/N ratio of 123dB or more and THD+N of less than 0.00035%. - [Fully balanced headphone amplifier circuit achieves 1400mW output] The K11 thoroughly implements a fully balanced headphone amplifier circuit, with one amplifier per left and right channel, for a total of two. In balanced output, it delivers up to 1400mW at 32Ω load and up to 250mW at 300Ω load. To suppress power supply noise that can affect sound quality, each circuit block has its own independent power supply design. Power supplied from the 12V external power source is kept clean by a low-noise LDO for each block, then adjusted to an appropriate level and supplied to the components. - [3-level gain control supports a wide range of listening environments from IEMs to headphones] The K11 allows gain adjustment through the LCD display on the front panel, with three levels: High, Mid, and Low. Adjust the gain to match the sensitivity of the connected earphones or headphones to enjoy music at a comfortable volume level. - [Versatile inputs and outputs for use at the center of an audio system] The K11 supports digital inputs via USB, RCA coaxial, and square optical terminals, analog output via RCA terminals, single-ended output via the 6.35mm headphone terminal, and balanced output via the 4.4mm terminal. Beyond PC connection, it can connect to various digital devices for high-quality balanced listening and can be easily integrated into an existing audio system. - [Front display and knob allow intuitive changes to unit functions] The K11 is the first FIIO desktop headphone amplifier to feature a display on the front. The high-contrast, durable VA display offers good visibility, no burn-in, and can stay on at all times. Sampling rate, volume, gain, and output mode can be checked visually. The front knob is used to turn power on and off, switch inputs, operate menus, adjust volume, and perform other functions. Pressing the knob twice quickly exclusively selects headphone output or RCA output, and each output remembers its last volume setting. Select the appropriate output mode when connecting to active speakers or when using the K11 as a pure DAC connected to an external amplifier. - [RGB indicator light in the logo area on the top of the unit] The FIIO logo on the top of the K11 is illuminated by RGB lighting, allowing quick identification of the current audio sampling rate. Brightness, color, and light pattern can all be adjusted with the knob. - [Refined, simple housing design available in black or silver] The K11 is assembled from carefully processed, highly rigid aluminum alloy. Its height is approximately 32mm and its width is 143mm, giving it a compact size that fits neatly on a desk. It is available in black and silver to suit your preference.
