K13 R2R
Fully differential true 24Bit R2R DAC resistor arrays | NOS/OS dual modes | 2400mW+2400mW powerful output | LDAC Bluetooth DC/AC dual power supplies | 10-band high-precision PEQ | Fully balanced audio amplifier circuit | XLR+RCA preamplifier / line output.
Fully differential True 24bit R2R DAC Resistor Arrays
FiiO's proprietary four-channel fully differential 24-bit R2R resistor array DAC is composed of 48 precision thin-film resistors across 4 channels. Each resistor features 0.1% accuracy and low temperature drift (30ppm). This R2R DAC allows the K13 R2R to deliver a uniquely rich and musical sound.
Comparison Between Fully Differential and Typical Architectures
The K13 R2R employs a fully differential architecture that leads to lower noise, and fewer FFT harmonics, resulting in a darker music background.
Dual NOS/OS Modes Double the Fun
NOS (Non-Oversampling) Mode: Maintains the original sampling rate for decoding, preserving authentic sound and allowing you to enjoy an organic and captivating music experience.
OS (Oversampling): Unsamples globally to a high sampling rate of 384kHz, for superior audio performance and even more refined, clear sound.
Preamplifier + Power Amplifier Output. Desktop Decoding Hub
With a wide variety of inputs and outputs, this unit functions as both a preamplifier and a power amplifier, catering to various listening preferences. It also supports PCM 384kHz/32bit and DSD256 decoding, allowing it to effortlessly process high-resolution audio signals to deliver rich sonic detail and for an outstanding listening experience.
Ten-Band High-Precision PEQ. Effortless Sound Customization.
The K13 R2R, with the kelp of the XMOS XU316 platform, features specifically developed PEQ, with support for 10 frequency band adjustments across all operating modes. With FiiO's proprietary tuning algorithms, accessible through their app or web interface, you can easily utilize preset tunings like "Retro PEQ” or even simulate and correct headphone frequency curves. It also supports exporting, importing, sharing, and saving EQ curves, and auto-EQ making sound tuning effortless.
Fully Balanced Audio Amplifier Circuit
The entire audio chain, including the R2R DAC, LPF, volume control, and headphone amp, uses fully differential signal processing for excellent interface rejection, minimal distortion, and high dynamic range. The amplification circuit also features gain control, headphone protection mechanisms, and POP noise elimination for a robust and reliable audio experience.
Specially Designed Power Supply
The built-in 30W switching power supply is protected by an alloy nickel-plated shielding cover, which significantly boosts its anti0interference capabilities and ensure a cleaner power supply. Additionally, it also features external DC power input, allowing you to pair it with a higher-performance linear power supply for a different sound experience.
Multi-Rail Power Supply, Robust Performance
With up to 18 low-noise LDO's and 5 DC-DC converters in total, this unit employs a multi-rail power supply to provide strong and clean power for exceptional audio output.
High Quality | ELNA RA3 Audiophile-Grade
Premium ELNA RA3 series silk-film audio capacitors and specialized audio tantalum electrolytic capacitors work together to ensure a pure, stable power supply for the device, delivering a warm and natural sound.
Robust Output Revealing Every Last Detail
Boasting a balanced output power of 2400mW+2400mW into 32Ω load, the K13 R2R can effortlessly drive both high-fidelity IEMs and headphones, unlocking their full potential and allowing them to render every last detail.
Superior Screen. Superior Clarity.
A custom, high-contrast, long lasting HD LCD display clearly shows the device's current status at a glance, including sampling rate, volume, gain, and output mode.
Adjustable RGB Logo Lighting
With support for Bluetooth 5.4 and reception for the LDAC/AAC/SBC codecs, the K13 R2R allows you to be immersed in a world of high-quality music even when listening wirelessly.
Precisely Designed. Perfect Performance.
Different gain levels mean the K13 R2R is better able to adapt to various kinds of IEMs and headphones for better listing experiences. Moreover, volumes of PO and PRE can be memorized independently.
Overheating Protection, Overload Protection.
Protection mechanisms will automatically kick in when abnormal operating conditions are detected to avoid damage to the unit, making it safer to use.
Adjustable RGB Lighting
Not only does the RGB lighting indicate the current audio sampling rate, but you can also customize the brightness, colours, and weather it pulses or not.
1 to 99 Minutes Timer Shutdown
Convenient functionality, meeting your needs.
