Product brief: Within the ES9023, the patented ultra line stream (Hyperstream) architecture and time domain jitter cancellation technique are employed to achieve jitter free recording quality, with dynamic range of 112dB. Since the integrated charge pump can generate negative voltage, the ES9023 can output 2Vrms directly at the reference ground under the single power supply, thus eliminating the coupling capacitance of the isolation. Moreover, the output amplitude can be set at resistance less than 2Vrms level by actual resistance. Switching machine noise is also fully inhibited. Product details: Using SA9023 ES9028K2M The main circuit of electrolytic capacitor signal adopts electrolytic capacitor from Japan, which guarantees strong and continuous . PCB uses 1.6mm thick double panel, 2.0A thick copper, tin spraying process to good passing performance of large and small currents. First-class PCB quality. Supporting maximum 24-bit 96K sampling rate, supporting: 33K, 44.1K, 48K, 88.2K, 96K sampling rate.
