FiiO K11 Compact Desktop R2R Architecture DAC and Headphone Amplifier

Description

Brand: FiiO

Color: silver

Characteristics:

  • Fully Differential 24-bit R2R DAC Array – FIIO has introduced its newly developed four-channel fully differential 24-bit R2R resistor array on the K11 R2R. It consists of 48 resistors per channel, a total of 192 high-precision ultra-thin film resistors with 0.1% accuracy and low temperature drift between the four channels. It promises clean and crisp output with a dark background thanks to the specially designed audio circuit architecture.
  • NOS/OS Dual Operating Modes – The FIIO K11 R2R features NOS (Non-Oversampling) and OS (Oversampling) dual operating modes. These are freely switchable and offer dual sound characteristics with the device. NOS mode maintains the original sampling rate during signal processing, while OS mode oversamples all signals to 384 kHz for processing. NOS mode results in more musical presentation, while OS mode delivers more detail and clarity.
  • Powerful Amplifier Section – FIIO has equipped the K11 R2R with a professionally designed amplifier circuit. It consists of a Ti OPA1642 low-pass filter and two SGM8262 professional operational amplifiers. The K11 R2R has an output power of up to 1300 mW x 2, which is sufficient to drive demanding headphones with ease. It features three-stage gain modes for easy pairing with both sensitive and powerful devices. The K11 R2R also adopts the precise NJW1195A digital volume chipset for precise volume adjustment with low distortion between channels.
  • Two headphone outputs: The FIIO K11 R2R features two headphone outputs. They consist of a single-sided 6.35 mm jack and a balanced 4.4 mm jack. You can easily pair various IEMs and headphones with the K11 R2R and enjoy high-resolution music in all its glory.
  • True High-Resolution Audio Signal Processing – The FIIO K11 R2R supports decoding for high-resolution audio signals. It offers full support for PCM and DSD signal processing, supporting up to 32-bit/384kHz PCM and DSD256 audio signals. DSD256 requires the DSD output mode to be set to native. It is internally converted to PCM for R2R signal processing.
  • Professionally Designed Low-Noise Power Supply – The FIIO K11 R2R features a professionally designed low-noise power supply. It consists of 17 low-noise LDO precision voltage regulator ICs and two DC-DC converters, providing multi-channel power delivery. It also benefits from an external 12V power supply, ensuring clean output with low noise and distortion. The K11 R2R delivers high-quality sound to its users.
