Sometimes, you may not have access to a device that can connect to the new K3 via USB Audio Class 2. In these situations, you can go to USB Audio Class 1 mode with just the flick of a switch.

 

 

* Using the 2.0 mode requires downloading and installing the FiiO USB driver

* After switching USB modes, you need to either turn the new K3 off and on, or unplug and plug in the USB cable.

In high-performance applications, you can use the 2.0 mode to enjoy up to 384kHz/DSD 256 decoding.

Two modes for many situations

 For certain situations, you can use the 1.0 mode to enjoy up to 96kHz/24-bit PCM audio without needing any drivers.

Coaxial and Optical digital outs

The XMOS USB receiver chip in the new K3 directly converts any USB audio input to digital signals output via the coaxial and optical connectors, allowing you to connect to speaker systems, amplifiers, or other external decoders.

 

*The volume knob does not control digital output volume. The New K3 can output digital audio signals up to 192kHz and DSD64 over DoP. Please adjust the settings of the device you are connecting the NEW K3 to if the device does not support the digitally output format.

A distinctly cohesive tactile audiovisual experience

The volume knob, with 45° notches etched onto its surface and perfectly sized to allow easy one-finger operation, is designed to perfectly blend in with the curves of the new K3 body for a distinctive touch. Next to the volume knob is an RGB light that indicates what kind of digital audio is being input to the new K3, visually confirming what you are hearing in your music. 

 

48kHz sampling rate and below - Blue
Above 48kHz sampling rate - Yellow

Being optimized for indoor desktop use, the new K3 is equipped with both 3.5mm single-ended and 2.5mm balanced headphone jacks. Both outputs have audio jack detection, which means that when headphones are inserted into the balanced out, balanced boost automatically kicks in resulting in about a 50% output power increase compared to the single-ended out.

Dual headphone jacks

Line out connector

The 3.5mm line out is driven directly by the OPA1612 op-amp, to ensure as little sound quality reduction as possible. The line out output is also adjustable with maximum power output up to 2Vrms, to ensure compatibility with a wide variety of active speakers and external amplifiers.

*When using the line out, please disconnect any headphones

Tiny round goodness in the palm of your hand

The all-aluminum black body has been painstakingly CNC-machined, anodized, and sandblasted to ensure that the new K3 feels robust yet perfectly textured for a great feel in your hands. Combined with its small size, you can easily take the new K3 wherever you need to.

Different connection options for different scenarios

Compared to the last generation K3, FiiO has noticeably improved on various performance indicators and overall sound quality, so you can get immersed in your music even more easily.

 

Simply reliable USB power

The new K3 adopts the modern USB Type-C input interface for a more reliable and stable connection, including that of power. However, care to ensure an uncompromised power supply doesn't stop there – the new K3 implements overvoltage protection (OVP) and a double-filter circuit to ensure power supply stability, while the digital and analog audio circuits each get their own power supply to greatly reduce crosstalk.

Just connect the new K3 to your computer via USB to instantly upgrade to high-fidelity sound, and enjoy your music the way it was meant to be heard. Equipped with an XMOS USB receiver chip, the new K3 is capable of decoding up to 384kHz/32 bit PCM and native DSD256 – the same as many DACs costing much more. The new K3's dual crystal oscillators ensure that any digital audio signals being fed into the DAC are exactly correct for further enhanced sound quality.

Low and High gains

ADC volume control

The switch for high and low gain meets your listening volume needs of delicacy and large dynamics. Plus an ADC volume control, the user is able to smoothly adjust the volume to a more accurate and finer degree, allowing the new K3 to be used with headphones of all kinds of sensitivity to really make your songs, games, and movies come to life.

 

Great "core" improvement

 

 

·SNR increased by 12%

·Distortion (THD+N) reduced by 12%

 

 

The new K3 employs the flagship portable ESS DAC, the ES9038Q2M. Compared to the AK4452, the signal-to-noise ratio has increased by 14dB and distortion has reduced by 13 dB. The circuit design implementing this DAC has been optimized for a low noise floor and clean sound.
