This is a bare PC board and kit of THAT ICs for the MS Matrix based on the design published in the Pro Audio Design Forum and used by mastering facilities world-wide. The Precision MS Matrix uses THAT1240-series line receivers with resistor matching of 0.005% to perform high accuracy mid-side sum and difference functions. The crosstalk performance is typically >60 dB across the full audio band.
The Mid Side Mini M/S Matrix provides simultaneous encode/decode capability. THAT1246 line receivers and THAT1646 OutSmarts® line drivers provide fully-balanced I/O for the encoder and decoder inputs and outputs.
With most material Mid has excess level and Side too little level. The Mid Side Mini provides jumper-selectable -6 dB gain offset in the encoder to reduce Mid channel build-up. The Side channel can also provide +6 dB of encoder gain by swapping encoder ICs from a THAT1240 to a THAT1246. (Both are included in the "kit.") Mid and Side decoder levels are jumper-selectable to compensate for encoder gain offsets.
The construction thread for the Mid Side Mini M/S Matrix is featured in the Pro Audio Design Forum.
The Mid Side Mini MS Matrix is sold as either a bare PC board, a "kit" including THAT1240, THAT1246 and THAT1646 ICs, or an assembled and fully-tested module.
A Mouser Electronics Project Manager bill-of-materials is available for DIY builds of the Precision MS Matrix.
