Fosi Audio C3 Gaming Sound Card & DAC/Amp
The Fosi Audio C3 is designed as a focused gaming audio hub for competitive play and everyday entertainment. Its StepSense„¢ mode detects and enhances footsteps in real time, helping you track movement more precisely in FPS games while keeping gunfire and explosions unchanged. For users comparing a desktop DAC with a gaming sound card, the C3 combines both roles in one compact unit.
Inside, the C3 uses an XMOS XU316, CS43131 and dual TPA6120 chipset configuration to deliver clean separation, detailed imaging and precise directional audio. As a headphone amplifier, it supports 16 to 300 ohm headphones and provides L+R ‰¥ 320 mW + 320 mW at 32 ohm with THD+N below 1%. USB audio supports up to PCM 32-bit/384 kHz and DSD256 via UAC 2.0, while optical and coaxial inputs support PCM 24-bit/192 kHz.
The C3 also improves communication during gaming, streaming and calls. Its noise cancellation reduces background distractions such as keyboard clicks and fan noise with up to 40 dB deep noise reduction. The browser-based control hub lets you switch between sound presets or fine-tune EQ settings without installing dedicated software, making it easy to adapt the sound for competitive FPS, casual gaming, movies or music.
Connectivity includes coaxial, optical, USB-C for power and data, a 3.5 mm microphone input, 3.5 mm headphone output and RCA output for desktop speakers. The package includes the Fosi Audio C3, user manual, USB-A/C to USB-C cable and Y-splitter cable, useful when integrating the unit with headsets and other audio cables. A solid all-aluminum alloy chassis, compact footprint, tactile buttons and sliders, and 5° angled design keep operation comfortable on a clean desktop setup.
