8 × CS43198 DAC The X8 features eight Cirrus Logic CS43198 DAC chips in a true dual-mono parallel architecture, with four DACs operating in parallel per channel. Left and right channels are fully independent in power supply, circuit layout, and signal path, minimizing crosstalk and interference. The parallel analog outputs are precisely summed to reduce noise and improve dynamic range, signal-to-noise ratio, and low-level detail, resulting in stable imaging and clear spatial presentation. A dedicated high-speed data buffering and distribution circuit ensures all DACs operate within the same reference clock domain, maintaining precise synchronization and preventing timing mismatch. DAC Dedicated Shielding Each of the eight CS43198 DACs is equipped with a custom shielding cover, which isolates the DACs from digital circuitry and high-frequency interference while assisting heat dissipation and thermal balance. This design reduces noise and jitter, ensuring stable and consistent performance during long-term, high-resolution playback. Digital Audio Core The DigitalAudio Core in the X8 is a high-performance processing module deeply customized by Luxsin and the first of its kind to be applied in a professional audio product. Built on a dual-core HiFi-5 DSP and ARM STAR architecture, with large on-chip SRAM and a DSP operating at over 500 MHz, it delivers the computational headroom required for complex real-time audio processing and advanced tuning algorithms. Its scalable design also enables edge-level AI audio processing, equipping the X8 with strong digital audio capabilities and long-term potential for continuous feature expansion. HP-EQ System HP-EQ is Luxsin's proprietary acoustic technology that performs hardware level EQ calibration, aligning your headphones' frequency response precisely with the Harman curve or other preset target curves, unlocking multiple "personalities" from a single pair of headphones. With a growing database of over 2,500 headphone models, HP EQ delivers accurate, personalized audio matching for every listener. The AI Era of PEQ World's First AI Assisted EQ Tuning, a revolutionary way to personalize your music. The AI instantly tailors the overall sound profile or fine tunes specific details with a simple voice/text command, delivering effortless, precise results. Professional grade tuning is now accessible to all. Control it seamlessly through the mobile app or PC web UI, with full multilingual support, for a truly flexible and intelligent listening experience. Comprehensive DSP Functions Crossfeed: Simulates natural speaker listening by blending left and right channels, reducing ear fatigue and enhancing sound realism. Stereo Width Adjustment: Freely control soundstage width from intimate to expansive, to perfectly match different music genres and personal preferences. Tone Adjust: Fine-tune the overall tonal character with intuitive controls, shaping the sound to match your listening taste quickly and easily. Loudness: Intelligently compensates for low- and high-frequency details at lower volumes, ensuring balanced, full-bodied sound at any listening level. Variable Linear Power Supply Adopts a fully separated linear power supply, with digital and analog circuits independently powered. This design isolates noise coupling and interference between circuits from the source, significantly enhancing sonic purity, background darkness, and laying a stable, clean power foundation for overall sound quality. The system integrates multiple voltage and current monitoring sensors for real-time power supervision. It also supports an adjustable dual analog voltage design (12V and 15V), further improving the flexibility and controllability of the power system. Upgraded Output Power The X8 employs a optimized headphone amplifier design using multiple OPA1612 op-amps and TPA6120A2 high-current drivers to independently drive each channel, delivering a powerful output of L+R ≥ 4800 mV + 4800 mV with extremely low distortion and high linearity. It effortlessly drives even the most demanding flagship headphones, offering strong dynamics, fast transients, and precise detail retrieval. Impedance Detection The upgraded headphone impedance detection system now covers all output interfaces (XLR4, 4.4mm, and 6.35mm), enabling precise impedance auto-detection and automatic matching of the optimal gain setting. Utilizing Luxsin’s proprietary bypass detection technology, the system operates completely isolated from the main audio path, guaranteeing absolutely no impact on sound purity. Users enjoy both accurate impedance matching with smart gain adjustment and uncompromised high-fidelity audio quality. User Settings Memory Automatically saves independent settings for each output port, including key parameters such as volume, PEQ, sound effects, and crossfeed. When switching outputs, the system instantly recalls the corresponding configuration, eliminating the need for readjustment and delivering a true plug-and-play experience. Luxsin Controller The X8 supports multiple flexible and convenient control methods, including mobile device apps (Android/iOS), computer web-based control (Windows/macOS), and an optional IR remote (sold separately). The device firmware supports both local and online updates, ensuring continuous optimization and an ever-evolving user experience. Signature Exterior Design The X8 continues Luxsin’s classic design language, featuring a 4.0-inch 1080P (960×480) full-color touchscreen that delivers sharp, detailed visuals and a smooth, intuitive user experience. Its front panel is tilted at a 15° ergonomic angle, enhancing visibility and ease of operation in daily use. Crafted from a solid CNC-machined aluminum chassis, it offers both premium tactile feedback and exceptional thermal dissipation. Versatile Connections The X8 is equipped with a range of digital audio input interfaces, including USB-B/C, Optical, Coaxial, and IIS, to accommodate various source devices. The IIS input supports up to eight custom configurations, ensuring compatibility with multi-type digital sources from different brands. It also features 12V Trigger in/out terminals, enabling seamless integration into existing audio systems for smoother device synchronization and automated control, making the entire system easier and more efficient to operate.
