随时随地都能可靠监听

诺音曼自动校准是一款专用工具,用于带有或不带有KH 750 DSP的KH 80 DSP音箱的立体声设置,以及连接到KH 750 DSP低音喇叭模拟输出的两个非DSP的KH-Line监听音箱。与传统的校准软件不同,它是采用新颖算法的集成解决方案,是与弗劳恩霍夫集成电路研究所(IIS)联合开发的,校正数据直接存储在DSP控制的监听音箱中进行处理。作为一项独特的优势,该软件不仅可以优化幅度响应,还可以优化相位。因此能够在音调和脉冲再现方面提供最高准确性。

工作原理

首先,在引导过程中收集聆听环境的声学数据。不需要特殊的声学知识。只需把诺音曼监听音箱连接到音频接口或音箱控制器的输出即可。此外,基于DSP的KH系列监听音箱也必须连接到计算机的以太网端口。如果有多个连接,可以使用标准以太网交换机。

然后将测量话筒插入麦克风输入,此话筒是专门为这个软件开发的,并由其单独进行校准。软件将指导您完成测量过程。根据测量的数据,该软件可以确定房间的声学特性,通过软件计算的特定房间目标曲线而生成每个校正参数。诺音曼在录音棚调音台中校准监控系统的数十年经验已被整合到该流程中。当然,您也可以根据需要修改目标曲线。

另外,使用低音喇叭时,校准过程可确保低频的最佳结合。

采集的校正参数都存储在采用DSP的监听音箱中进行处理。因此,无需担心没有插件或没有驱动程序的问题,而且也不需要其他连接线:校准过程完成后,就不再需要以太网连接。

Multichannel Extension

MA 1 Automatic Monitor Alignment delivers outstanding acoustic results for stereo setups. For aligning surround and immersive setups, Multichannel Extension for MA 1 is available as a paid extra license. For detailed information on Multichannel Extension for MA 1, go here .

使用KH 750 DSP低音喇叭,模拟KH系列音箱的立体声设置也可以与自动音箱校准软件一起使用。 KH 750 DSP具有足够的处理能力,可以校准整个系统,包括连接到其输出的两个模拟扬声器。此外,KH 120、KH 310和KH 420监听音箱还得益于内置分频滤波器的相位线性化!最终提高了清晰度、纯低音,并且对混响和声音空间进行了准时且更精确的描绘。

展望未来

MA 1自动监测校准标志着一个新监听时代的开启。从可为立体声设置提供出色声学效果的当前版本开始,软件功能的范围将通过更新而逐步扩展。

Hardware requirements

Loudspeakers and subwoofers (stereo systems)

  • 1 pair of KH network-enabled loudspeakers or
  • 1 or 2 KH network-enabled subwoofers in combination with a pair of KH network-enabled loudspeakers or a pair of KH analog loudspeakers Note: Stereo systems may comprise Bass Management.

Peripheral Equipment

  • Neumann MA 1 measurement microphone
  • PC or MAC
  • Screen resolution of 1280 × 720 px or higher
  • Audio interface with:
    • 1x balanced analog mic input with 48 V phantom power.
    • Audio output channels equal to or greater than the number of network-enabled loudspeakers and subwoofers used in the monitoring system. Outputs may be balanced analog, S/PDIF (KH 120 II or KH 150 loudspeakers only), or AES3 (KH 750 subwoofer only).
    • Network switch offering a number of free sockets equal to or greater than the total number of loudspeakers and subwoofers employed in the monitoring system. Each loudspeaker and subwoofer should be connected from its Primary network socket to a free socket in the network switch.

Software requirements

  • Operating system:
    • PC: Windows 10/11 64 Bit
    • Mac: macOS 10.15, 11, 12, 13, 14
  • MA 1– Automatic Monitor Alignment software
  • ASIO driver (for Windows)

Network-enabled loudspeakers (DSP loudspeakers)

The following loudspeakers and subwoofers are network-enabled and can be controlled directly by MA 1:

  • KH 80 DSP
  • KH 120 II, KH 120 II AES67
  • KH 150, KH 150 AES67
  • KH 750 DSP, KH 750 AES67

Non-network-enabled loudspeakers (Analog loudspeakers)

The following loudspeakers are not network-enabled and need to be connected via a network-enabled subwoofer in order to be included in the system setup. Please note, that each network-enabled subwoofer controls a single monitor when used in Multichannel layouts.

  • KH 120 A, KH 120 D
  • KH 310 A, KH 310 D
  • KH 420 / KH 420 + DIM 1

重要信息

请注意:

  • 校准流程完成后,MA 1软件将校正数据存储在音箱或低音喇叭中,而不是存储在软件应用中。因此,对校准系统进行进一步操作无需计算机与以太网连接。目前,一旦软件关闭,存储在音箱中的数据就无法调出或更改。校准程序必须从头开始,再重复一遍。
  • 以下情况目前适用:如果音箱之前是用Neumann.Control iPad®应用进行调整的,那么它们的校正数据将被MA 1软件进行的校准覆盖。
  • 如果再次打开Neumann.Control iPad®应用,该应用中存储的最新数据将发送到音箱,从而覆盖MA 1生成的校准数据。
  • 通过MA 1软件进行校准设置。 MA 1软件目前无法控制其它参数(例如静音、音量、延迟等)。
  • MA 1软件不包含Neumann.Control iPad®应用上的引导校准或手动校准功能。
