Neumann Multichannel Extension for MA 1 (ESD); extension for an exisiting Neumann MA 1 hard / software solution; Caution - upgrade version! Requires a registered license of Neumann MA 1 (item 508756)!; works with all network-enabled KH Line studio monitors from Neumann; suitable for Quad, 5.1, 7.1, 5.1.4 and 7.1.4 setups with up to 4 subwoofers; precision acoustical alignment for immersive sound that translates reliably to all compatible playback systems; linearizes the frequency response and optimizes localization of the entire system; generates a room-adaptive target curve with detection of room modes and automatic filter optimisation; compensation of level differences and differential delay; corrects spatial imperfections in e.g. stereo control rooms for use of multi-channel setups; helpful to avoid changing the sonic character when panning sources and to prevent from misinterpretation of sonic variations as directional information
