唱盘系统

概览

音乐爱好者往往既追求黑胶唱片独特的音质魅力，又离不开数字播放和存档的便利性。 这款唱盘系统提供流畅的电机控制、干净的电源和精确的音频处理，确保丰富的音质和便捷的 USB 连接体验。 超低功耗电机控制 MCU 可确保精确的旋转速度，而用户可调开关则可实现个性化的播放控制。 同步降压稳压器可将 24V 电压有效降压至 3.3V，且 LDO 可将噪音降至最低，从而实现纯净的音频性能。 运算放大器驱动的 RIAA 前置放大器可重现模拟声音，通过 RCA 连接为放大器或有源扬声器提供暖音频。 通过 USB 输出，用户可数字化黑胶播放，用于定制播放列表、效果或录音。

系统优势：

  • 用户可通过开关进行设置，获得个性化的播放体验
  • 通过运算放大器提高音频质量，最大限度地减少噪音和失真
  • 为敏感音频元件提供干净且稳定的电源
