beyerdynamic Opus 65

Hypercardioid Dynamic Microphone

The Opus 65 is a dynamic kick-drum mic with a hypercardioid moving-coil cartridge — Beyerdynamic’s TG-X 80 capsule, also used in the M 99 TG, Opus 99, and TG-X 50 microphones.

Beyerdynamic states that the Opus 65 is identical to the TG-X 50, and in fact replaced it in Beyerdynamic’s product line. But this refers only to the “Mk II” version of the TG-X 50, which first incorporated the passive EQ filter circuit diagrammed at right. This filter attenuated the mid frequencies in an apparent effort to produce a tailored response for kick-drum miking.

This mic was recommended in Electronic Musician’s “How to build a personal studio on any budget” article (in 2002).
