Studio-Grade Mixing Control on Your Desktop

Inspired by professional mixing consoles, the R3 features physical faders and large rotary knobs, bringing studio-grade mixing control right to your desktop. The appearance design combines intuitive operation with a professional aesthetic, allowing you to adjust audio settings with precision and ease. Whether you are gaming, producing music, or simply enjoying HiFi audio, the tactile controls provide a satisfying and responsive experience that sets the R3 apart from conventional desktop DACs.

Powerful Hardware with 10-Band Independent EQ

The R3 adopts a CS43131 DAC chip with built-in high-performance DSP digital processing, achieving THD+N as low as 0.00045% (106dB) and a dynamic range of 118dB. Its 10-band independent EQ lets you adjust each frequency band from 31Hz deep bass up to 16kHz high treble, with an adjustment range of -10dB to +10dB. Fine-tune vocals, fix headphone timbre, and optimize audio in real time to suit your personal preferences and listening scenarios.

Dual CrinEar Dynamic Driver System

The R3 functions as both a desktop USB DAC and headphone amplifier, supporting PC, Mac, game consoles, mobile phones, and other audio sources. It also works as a professional DSP digital mixing console. Through its OPT optical output interface, it is widely compatible with mainstream decoders on the market, allowing the R3 to serve as an external DSP mixing processor for decoders and providing audio systems with greater flexibility for sound customization.

Desktop USB DAC and Digital Mixing Console

The R3 features dual headphone output ports for gaming voice chat and HiFi listening in one device. The HO MIC 3.5mm headset jack supports headsets with built-in microphones, while the HO BAL 4.4mm balanced headphone jack drives high-impedance headphones for rich, detailed audio. Microphone inputs include OFF, HO MIC, and MIC 1 with 48V phantom power, combined with an independent microphone volume booster that enhances vocal clarity and detail expression for efficient communication.

Dual Headphone Outputs for Gaming and HiFi

The USB input supports two USB modes, with the UAC1.1 driver-free mode enabling connections to various gaming consoles such as Sony PS4/PS5 and Nintendo Switch. The default mode for R3 is UAC2.0. Press and hold the volume up knob for 5 seconds to switch to UAC1.1 driver-free mode, then press and hold again for another 5 seconds to revert to UAC2.0 mode. Note that UAC1.1 mode supports a maximum sampling rate of 16 bits/48kHz.

Game Console Support with UAC1.1 Mode

The R3 includes a built-in headphone amp, so no extra amplifier is required — simply plug and play for headphones and fully unleash their performance. Independent left/right VU meters provide real-time audio level monitoring for intuitive status viewing. One-click EQ mode switching quickly adapts to gaming, music, and movie scenarios. A dedicated screen protector film isolates dust, fingerprints, and scratches, while supplementary power input (Type-C, 5V/2A) ensures stable operation.
