Multitrack Microphone Circuit Kit

This kit creates a neutrally-voiced, large-diaphragm condenser microphone that allows you to choose the polar pattern at mix time. It has separate outputs for the front and rear halves of the capsule; by recording both to independent tracks, you can control the effective polar pattern after tracking is complete. (See the mix matrix below.) The circuit is our acclaimed transformerless design, implemented with high-grade parts. The circuit incorporates a next-generation corrective EQ option. The finished mic has high output (~35mV/Pa), low noise, low distortion, and a very smooth (not bright or harsh) response. It is suitable for voices, acoustic instruments, foley, and ensemble miking. We offered a version of this kit in April 2020. We have revised, updated, and upgraded the product; the new version was introduced in June, 2023.   In The Box This kit contains: two circuit kits for DIY assembly a 5-pin XLR insert to be retrofitted into the donor mic a selected RK-87 capsule (value $16
