Pro Audio USB Interface Kit: XMOS 2CH, ES9018/ES9822, Soundcheck/REW Support, 10Vp Balanced I/O
Product Advantages & Features
Flagship Audio Chips & XMOS Core Architecture
- ADC (ES9822): 118dB dynamic range, 24bit/192kHz sampling, -120dB THD+N, ideal for high-precision recording.
- DAC (ES9018): 120dB dynamic range, 0.0002% THD+N, ±0.05dB frequency response (20Hz-20kHz), delivering studio-grade playback quality.
- XMOS Multichannel Solution: Supports 2/4/8-channel expansion (customizable up to 64 channels), USB asynchronous transmission reduces jitter for ultra-low-latency audio streaming.
Professional-Grade Audio Performance Metrics
- Signal-to-Noise Ratio (SNR): 116dB (overall), 118dB (ADC), 120dB (DAC, 20Hz-20kHz unweighted), rivaling premium professional equipment.
- Total Harmonic Distortion + Noise (THD+N): 0.00025% (@1kHz, -1dBFS), meeting stringent demands for audio analysis and acoustic measurement.
- Frequency Response Flatness: ±0.05dB (20Hz-20kHz), ensuring lossless signal transmission across the entire frequency spectrum.
