FIIO K11 R2R

Fully-Differential 24-Bit R2R DAC

FiiO's K11 R2R features a newly developed four-channel, fully differential 24-bit R2R resistor array. Each channel has 48 resistors, totalling 192 high-precision ultra-thin film resistors with 0.1% accuracy and low-temperature drift. This advanced audio circuit architecture ensures clean, crisp output with a dark background.

True Hi-Res Audio Signal Decoding And Dual Operating Mode

The FiiO K11 R2R supports high-resolution audio decoding, handling up to 32-bit/384kHz PCM and DSD256 signals. It features switchable NOS (Non-Oversampling) and OS (Oversampling) modes.

Powerful Amplification Stage And Precise Volume Adjustment

The FiiO K11 R2R boasts professionally designed amp circuitry with Ti OPA1642 low-pass filters and dual SGM8262 operational amplifiers. It delivers up to 1300mW per channel, easily driving demanding headphones.

Seamless Connectivity With A Variety Inputs And Outputs

The FiiO K11 R2R offers versatile input and output options for diverse audio setups. It features coaxial, optical, and USB digital inputs, along with 4.4mm balanced, 6.35mm single-ended headphone output, and RCA analog line-out connections.
