Cardioid Condenser Microphone
The MXL M3 is a large-diaphragm FET condenser microphone. Part of MXL’s “Silicon Valve” product line, the M3 is said to “provide the sound of a tube” with its solid-state design.
The mic is a fixed-Cardioid design with a relatively high sensitivity of 22 mV/Pa and somewhat high self-noise of 18dBA. Its capsule is a 25mm-diameter large-diaphragm design, presumably center-terminated. The diaphragm is made of 6-micron Mylar.
The MXL M3 and V6 are manufactured in MXL’s facility in Southern California.
The M3 shipped with a ring mount (MXL p/n MXL-V6-H) and a padded storage box. Two versions were available:
- M3 - “standard” version
- M3-P - optimized for female vocals
Both “Silicon Valve” models were discontinued in 2010, reportedly due to the high cost and low availability of several critical components.
