Based on the MS matrix design from the Pro Audio Design Forum, this unit from KA Electronics performs high-precision mid/side encoding and decoding. Instead of the typical precision resistors, the Precision M/S matrix uses THAT1240 line drivers for the lowest possible crosstalk.

Notable Features:

• Simultaneous M/S encoding and decoding
• Fully balanced inputs and outputs
• Addition unbalanced input points
• Better crosstalk performance than traditional, resistor-based units

Price:

• $19.95 for PCB
• $63.95 for PCB and THAT ICs
