Neumann’s Automatic Monitor Alignment MA 1 ensures the best possible sound quality in any room – from home studios to professional control rooms. Using the individually calibrated measurement microphone your acoustic environment is analyzed in a guided process. Advanced algorithms, derived from decades of experience in aligning reference monitoring systems, guarantee optimally aligned frequency response, time of arrival and level for exact and reliable monitoring.

A unique benefit of the MA 1 Algorithm is precise and effective compensation of room modes. Using MA 1 results in increased clarity, consistency across monitors, dry bass, and time-correct, more accurate depiction of reverbs and acoustic spaces.



Neumann’s Automatic Alignment software MA 1 is a dedicated tool for aligning network-enabled KH Line monitors in stereo systems and stereo systems with Bass Management via an additional subwoofer. Non-network-enabled (analog) KH Line monitors can be aligned via MA 1 when connected to a KH 750 DSP/AES67 subwoofer.

Unlike conventional correction software, MA 1 is an integrated solution with novel algorithms, specifically designed for Neumann studio monitors. No plug-in or special audio driver is required: Alignment data is stored and processed within the DSP-powered loudspeakers themselves. For analog Neumann studio monitors (i.e. without a network port) connected to a KH 750 DSP/AES67 subwoofer, MA 1 offers the added benefit of linearizing the phase response, too. This feature, which is already built into all network-enabled loudspeakers with digital electronics, is made possible for analog Neumann studio monitors by the KH 750’s DSP capabilities. The result is further increased accuracy in terms of tonality, impulse reproduction, and stereo localization.


As a first step, the performance of each monitor in the listening environment is gathered in a guided process. No special acoustics knowledge is required. Simply connect your KH line monitors to the outputs and the MA 1 microphone to the input of your audio interface. This Class I measurement microphone was specifically developed for this software and comes individually calibrated. For communication, the network-enabled KH-line monitors must also be connected to your computer via a network, a standard ethernet switch supporting IPv6 will do.

From the measurement data, the software ascertains the room’s acoustic properties. The individual correction parameters are generated according to a room-specific target curve calculated by MA 1. Decades of experience in aligning reference monitoring systems in studio control rooms has been incorporated into this process. Of course, you can modify the target curve to your needs.

When using Bass Management in stereo systems, the alignment algorithm ensures optimal summation between subwoofers and satellites. This achieves optimized time-of-arrival- and

phase-correct combination of the monitors and the subwoofer, thus preventing the subwoofer from being perceived as a separate sound source. The result is a unified playback system.

Multiple hardware systems and alignments can be conveniently saved, managed and recalled in MA 1.

All alignment parameters are stored and processed in the network-enabled monitors. So, once aligned, there is nothing to worry about anymore, no plug-ins, no driver issues.

After alignment, the ethernet connections can be removed from a technical perspective. However, keeping the network connections, the MA 1 software allows for advanced functions such as deactivating the subwoofer(s) or switching between different alignment presets (e.g. with a modified target curve).

For more information, please refer to the MA 1 user manual:


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.

Using the KH 750 DSP subwoofer, stereo sets of analog KH-Line monitors, too, can be used with the Automatic Monitor Alignment Software. The KH 750 DSP has enough processing power to align the entire system including the two analog loudspeakers connected to its outputs. Additionally, KH 120, KH 310, and KH 420 loudspeakers profit from phase linearization of their built-in crossover filters! The result is increased clarity, a dry bass, and a time-correct, more accurate depiction of reverbs and acoustic spaces.

For the market launch we are offering attractive kits consisting of KH Line Monitors and the MA 1 package (see order info).


The MA 1 Automatic Monitor Alignment is the beginning of a new era in monitoring. Starting with the current version, which delivers outstanding acoustic results for stereo setups, the range of software functions will be expanded step by step with updates.

Important Information
Please note:
  • After the alignment process, the MA 1 software stores the correction data in the monitors or in the subwoofer. In addition, both the hardware setup and the alignment(s) created are saved in the software and can be changed later if required. Another continuous connection to the computer is only required if the loudspeaker setup is to be controlled via the MA 1 during operation. This includes level settings, bass management (if a subwoofer is connected) and setup or alignment changes.

Therefore, no Ethernet connection to the computer is required for further operation of the aligned system. Currently, the data stored in the loudspeaker(s) cannot be recalled or changed, once the software is closed. The calibration procedure must be started from the beginning and repeated.

  • The following currently applies: If the loudspeakers were previously adjusted using the Neumann.Control iPad® app, their correction data will be overwritten by an alignment with the MA 1 software. If you open the Neumann.Control iPad® app again, the last data stored in the app is sent to the loudspeakers, thus overwriting the correction data generated by the MA 1.
  • Alignment settings are made via the MA 1 software. Other parameters (e.g. mute, delay …) cannot currently be controlled by the MA 1 software.
  • The MA 1 software does not include Guided Alignment or Manual Alignment like on the Neumann.Control iPad® app.
