ADA8V3S 是用于 Merging 音频主机 Hapi Mk III 的复杂输入输出卡。它有八个输入和八个输出端，提供双向音频转换：模拟转数字和数字转模拟。
这些远程控制的麦克风/线路输入输出卡采用了第三代双增益拓扑结构，灵感源自卓越的 Anubis 前置放大器，可实现不打折扣的出色音质。
使用两个 ADA8V3S 8 通道麦克风/线路输入和线路输出卡，您可以为多达 16 个模拟 I/O 通道配置 Hapi Mk III。
ADA8V3S 支持高达 192 kHz 的采样率。
 

Features:

  • 8 个透明度极高的瑞士设计前置放大器，以及 8 个输出端
  • 线路输入端的动态范围为 139 dB（A 加权，典型值）
  • 前置放大器提供高达 78 dB 的增益（带提升功能）
  • 完全远程访问所有参数更改
  • 线路输入端的动态范围为 124 dB（A 加权，典型值）
  • 每个通道可切换幻象电源/极性反相/低切/阻抗
  • 通过主机显示屏或通过浏览器远程按通道切换到线路电平
  • 自动静音电路，实现“无爆音”电源循环
  • 用于校准程序的数控输出微调
  • 2 个 25 针 Sub D 连接器
  • 采样率高达 192 kHz
