The Neumann MA 1 Monitor Alignment Microphone and Calibration System is designed to help engineers, musicians, and producers get more accurate and sonically consistent mixes from their Neumann KH 80 DSP monitors or non-DSP KH-Series monitors when used with the KH 750 DSP subwoofer. The system uses an omnidirectional measurement mic and a downloadable software for Mac and Windows with Fraunhofer IIS algorithms to calibrate and adjust the phase and amplitude of the speakers to compensate for room imperfections. The system is easy to use; simply connect the balanced outputs of your audio interface or monitor controller to your KH monitors. Connect the ethernet ports of your DSP-based monitors into a network switcher (available separately) and then route the switcher output into your computer. Plug the calibration mic into a mic input on your interface (48V phantom power is required) and follow the calibration process in your software. An SG105 mic clip is included to mount the microphone to a stand.
