"CS43198" is a Master HIFI DAC that achieves the strict standards set by the company to provide audio playback that is truly faithful to the recording. By using this chip, we have achieved performance of S/N ratio: 123dB or more and THD+N: less than 0.00035%. [Achieved 1400mW output with a fully balanced headphone amplifier circuit] The K11 has a fully balanced headphone amplifier circuit and is equipped with two amplifiers, one for each left and right channel, achieving a balanced output of up to 1400mW when loaded with 32Ω and a maximum output of 250mW when loaded with 300Ω. Furthermore, in order to suppress power supply noise that adversely affects sound quality, we have adopted a power supply circuit design that supplies independent power to each block of the circuit. The power supplied from the external 12V power supply is kept clean by low-noise LDOs in charge of each block, adjusted to the appropriate amount, and then delivered to the components. [3-stage gain control supports a wide range of playback environments from IEMs to headphones] The K11 allows you to adjust the gain from 3 stages: High, Mid, and Low by setting it on the LCD display on the front of the main unit. You can always enjoy music at a comfortable volume level by adjusting the gain according to the efficiency of the connected earphones or headphones. [With a variety of inputs and outputs, it can be used as the center of an audio system] The K11 supports digital input using a USB terminal, RCA coaxial terminal, and square optical terminal, analog output using an RCA terminal, single-ended output using a 6.35 mm headphone terminal, and balanced output using a 4.4 mm terminal. Not only can it be connected to a PC, but it can also be connected to various digital devices to enjoy music with high-quality balanced connections, and can be easily integrated into the audio system you already own. [The display and knobs on the front allow you to intuitively change the functions of the main unit] The K11 is the first FIIO stationary headphone amplifier to feature a display on the front. The high-contrast, highly durable VA display provides good visibility and can be lit at all times without burn-in. Visually check sampling rate, volume, gain, and output mode. The knob on the front is used to turn the power on/off, switch each input, operate the menu, adjust the volume, and other operations. You can exclusively select the headphone output/RCA output by pushing the knob twice quickly, and each output can remember the last volume. You can select the appropriate output mode when connecting to active speakers or when connecting to an external amplifier as a pure DAC. [RGB Indicator Light on the Top Logo] The FIlO logo on the top of the K11 is illuminated with RGB lighting, allowing you to quickly identify the current audio sampling rate. Brightness, color and light pattern are all adjustable with knobs. [Sophisticated and simple housing design and available in two colors: black/silver] K11 is assembled from highly rigid aluminum alloy with careful processing of the material. It has a compact size of approximately 32mm in height and 143mm in width, so it can be placed neatly on your desk. Available in two colors, black and silver, you can choose according to your preference. K11 is an entry-level model of a compact, stationary headphone amplifier with a built-in DAC that has a slim body, abundant inputs and outputs, and high output. The K series, a stationary headphone amplifier with a built-in DAC that FIIO has developed over many years, has undergone constant evolution, and the latest model, the K11, combines a completely new body design with a fully balanced headphone amplifier circuit that delivers up to 1400mW of drive power and uncompromising audio playback quality. The LCD display allows intuitive operation of the main unit, making it a high-performance unit that blends in with your desktop space.
