The new FiiO K11 R2R offers advanced FiiO proprietary R2R DAC technology and versatile connectivity for desktop audio enthusiasts.
Fully differential 24-bit R2R DAC array
FiiO has equipped the K11 R2R with its newly developed fully differential 24-bit R2R resistor array with four channels.
It consists of 48 resistors per channel, totalling 192 high-precision, ultra-thin film resistors with an accuracy of 0.1% and low temperature drift between the four channels.
Thanks to the specially designed audio circuit architecture, it promises a clean and sharp output with a dark background.
NOS/OS dual operating modes
The FiiO K11 R2R has two operating modes, NOS (non-oversampling) and OS (oversampling).
These offer dual sound characteristics with the device.
In NOS mode, the original sampling rate is retained during signal processing, while in OS mode all signals are oversampled to 384kHz for processing.
NOS mode results in a more musical presentation, while OS mode delivers more detail and clarity.
Powerful amplifier section
FiiO has equipped the K11 R2R with a professionally developed amplifier circuit.
It consists of Ti OPA1642 as a low-pass filter and two SGM8262 operational amps.
The K11 R2R has an output power of up to 1300mW, which is enough to drive even most demanding headphones.
It features three-stage amplification modes that allow easy pairing with sensitive and power-hungry devices.
Two headphone outputs
FiiO K11 R2R has an SE 6.35 mm connection & BAL 4.4 mm output.
You can easily pair different IEMs and headphones with the K11 R2R and enjoy high-resolution music in all its splendour.
