RA-ES70DSP04 是一款具有内置开放标准 (AES70) 远程控制功能的专业音频 DSP 模块。DSP 模块包括一个 AES70 设备模型,因此任何兼容的控制器都可以订阅和控制其功能,以及一个基于网络的 AES70 用户界面。

音频处理与控制处理器分离,因此控制复杂性不会导致性能下降。专用的 DREAM DSP 拥有庞大的算法库可供选择,包括:

  • 分频滤波器:Bessel、Butterworth、Linkwitz-Riley
  • 参数均衡(最多 31 个频段)
  • 压缩器、限制器和噪声门
  • 延迟(时间对齐)
  • 混音、增益、峰值电平
  • 人声混响、弹簧混响等效果

RA-ES70DSP04 的真正优势在于设计工具,其中包括每个算法的编程模板,为您生成 DSP 用户界面控件。

RA-ES70DSP04 具有 3 x I2S 输入和 4 x I2S 输出,用于连接到音频转换器、SPDIF 接口或 AoIP 处理器。

AES70 接口在网络音频环境中使用时特别有效,无需大量单独的控制器。
The RA-ES70DSP04 is a professional audio DSP module with built-in open standard (AES70) remote control functionality. The DSP module includes an AES70 device model, so that any compliant controller can subscribe and control its functionality, as well as an AES70 web-based user interface.

The audio processing is separate from the control processor, so there is no performance degradation with control complexity. The dedicated DREAM DSP has a vast library of algorithms to select, including:

  • Crossover Filters: Bessel, Butterworth, Linkwitz-Riley
  • Parametric Equalisation (up to 31 bands)
  • Compressor, Limiter and Noise Gate
  • Delay (time alignment)
  • Mixing, Gain, Peak Level
  • Vocal Reverb, Spring Reverb and other effects

The real benefit of the RA-ES70DSP04 is the design tools, which include a programming template for each algorithm, generating the DSP user interface controls for you.

The RA-ES70DSP04 has 3 x I2S inputs and 4 x I2S outputs for connection to audio converters, SPDIF interfaces or AoIP processors.

The AES70 interface is particularly effective when used in networked audio environments, avoiding the need for numerous separate controllers.
