Neumann's automatic monitor alignment MA 1 ensures the best possible sound quality from home studios to professional control rooms. The individually calibrated measurement microphone analyzes your acoustic environment in a guided process. Advanced calibration algorithms, jointly developed with the world's leading institute in audio processing, Fraunhofer IIS, guarantee an optimally adapted amplitude and phase correction for exact and reliable monitoring.
The MA 1 is a dedicated tool for stereo sets of KH 80 DSP monitors with or without the KH 750 DSP as well as two non DSP-based KH-Line monitors connected to the analog outputs of a KH 750 DSP subwoofer. It is an integrated solution with novel algorithms, developed specifically for Neumann studio monitors. No plug-in or special audio driver is required: alignment data is stored and processed within the DSP-powered monitors themselves. The software not only optimizes the amplitude response, but also optimizes the phase. This provides highest accuracy in terms of tonality and impulse reproduction.
In the first step, acoustic data of the listening environment is gathered in a guided process. Simply connect your Neumann monitors to the outputs of your audio interface or monitor controller. DSP-based KH-line monitors must be connected to your computer's ethernet port, or a standard ethernet switch for multiple connections.
Next, plug the measurement microphone into your microphone input. Software guides you through the measurement process.
Data gathered from the microphone input ascertains the room's acoustic properties. The individual correction parameters are generated according to a room-specific target curve calculated by the software; you can modify the target curve. Additionally, the alignment process ensures an optimal summation in the low frequencies when a subwoofer is used. All resulting correction parameters are stored and processed in the DSP-powered monitors.
The MA 1 offers the beginning of a new era in monitoring. Delivering outstanding acoustic results for stereo setups, the range of software functions will be expanded step by step with updates.
