Whether you're an audiophile or a casual listener, the K11 R2R's innovative features ensure a superior listening journey.
State-of-the-Art 24-Bit R2R DAC Array
The K11 R2R is equipped with FiiO's cutting-edge four-channel fully differential 24-bit R2R resistor array. With 48 resistors per channel and a total of 192 ultra-precise resistors (0.1% accuracy and low-temperature drift), this array ensures a pristine output and a dark, noise-free background. This advanced circuit design delivers exceptional audio clarity and detail.
Versatile NOS/OS Dual Operating Modes
The K11 R2R offers dual operating modes: NOS (Non-Oversampling) and OS (Oversampling). Switch between these modes to enjoy different sound characteristics. The NOS mode retains the original sampling rate, providing a more musical and natural sound. In contrast, the OS mode upscales signals to 384kHz, offering enhanced detail and clarity. Tailor your listening experience to your preference with ease.
High-Powered Amp Section for Superior Output
Designed for audiophiles, the K11 R2R's powerful amp section includes TI OPA1642 low-pass filters and dual SGM8262 professional-grade operational amplifiers. With an impressive output power of up to 1300mW per channel, it can effortlessly drive even the most demanding headphones. The three-level gain adjustment ensures compatibility with both sensitive IEMs and power-hungry headphones, while the NJW1195A precise digital volume chipset allows for fine-tuned volume control with minimal distortion.
Dual Headphone Outputs for Maximum Flexibility
Featuring both a 6.35mm single-ended and a 4.4mm balanced headphone output, the K11 R2R offers versatile connectivity options. Whether you prefer single-ended or balanced connections, you can easily pair a variety of IEMs and headphones to enjoy high-resolution audio in its purest form.
High-Resolution Audio Support
The K11 R2R excels in high-resolution audio processing, supporting PCM and DSD signals up to 32-bit/384kHz PCM and DSD256. With native DSD output mode, your audio is processed internally to PCM for an authentic R2R experience. Enjoy every nuance of your music with true high-resolution signal decoding.
Professionally Engineered Low-Noise Power Supply
To ensure the highest sound quality, the K11 R2R incorporates a low-noise power supply system. It features 17 low-noise LDO precision voltage regulators and 2 DC-DC converters, providing a stable and clean power supply. The external 12V power supply further minimizes noise and distortion, ensuring a flawless audio output.
