FiiO K11 R2R DAC and Headphone Amplifier
Description
The FiiO K11 R2R is a high-performance desktop DAC and headphone amplifier designed for home audio or PC use. Featuring a fully differential true 24-bit R2R DAC resistor array, NOS/OS dual modes, and high output power, the K11 R2R offers an exceptional audio experience with support for PCM 384kHz/24bit and DSD256 decoding.
Features
- Fully Differential True 24-bit R2R DAC Resistor Arrays: The K11 R2R uses FiiO's self-developed four-channel fully differential 24-bit R2R DAC, consisting of 192 precision thin-film resistors with 0.1% tolerance and low temperature drift (30ppm), providing a unique and charming sound.
- Dual NOS/OS Modes: NOS (Non-Oversampling) mode preserves the original sampling rate for an authentic sound, while OS (Oversampling) mode upscales to 384kHz for superior audio performance.
- High-Quality Electronic Volume Control: The NJW1195A is a 4-channel electronic volume controller that offers low distortion, low noise, and precise volume adjustment.
- 3 Gain Levels + 3 Independent Volume Curves: These features allow the K11 R2R to provide an optimal listening experience with various types of headphones, whether sensitive earphones or harder-to-drive over-ear headphones.
- Specially-Designed Audio Circuit: The audio signal is processed through a digital audio bridge and FPGA before being decoded by the R2R DAC. It then passes through op-amps for low-pass filtering, precise volume control, and phase inversion, resulting in high-quality output signals.
- Specially-Designed Power Supply: The K11 R2R uses 17 low-noise LDO precision regulator ICs and 2 DC-DC converters for a multi-channel specialized power supply, ensuring purity and stability in power output.
- High-Quality Beryl Solid Capacitors: These capacitors offer ultra-low ESR and excellent anti-interference capabilities, providing a stable and clean power supply for high-quality sound.
- Powerful Output: With an output power of 1300mW+1300mW under balanced mode, the K11 R2R can easily drive a wide range of HiFi earphones and headphones.
- Custom LCD Screen: A high-contrast and durable LCD screen allows you to easily see the sampling rate, volume, gain, or output mode with just a glance.
- Multi-Function Volume Knob: The knob controls power, menu operations, volume adjustment, and mode switching, offering easy control over various functions.
- Adjustable RGB Logo Lighting: The FiiO logo is illuminated with RGB lighting that can indicate the current sampling rate and can be customized for brightness, color, and light patterns.
