• The following loudspeakers and subwoofers are network-enabled and can be controlled directly by the software:
• KH 80 DSP
• KH 750 DSP

• 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.
• KH120A

• KH310A
• KH310D
• KH 420/KH 420 + DIM 1

• After the alignment process, the MA 1 software stores the correction data in the monitors or in the subwoofer; not in the software application. 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, volume, logo brightness, 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 iPadapp.
