This little microphone has a natural, detailed and balanced response. Perfect for natural reproduction of acoustical instruments such as members of the bowed and plucked string-families, grand piano, brass, percussion, overhead choir and voice -with a minimum of colouration. The response is rather smooth and flat even at an angle!

The CM3 is tough enough to handle drums with full depth and punch, drum overhead clearly and crisp without strain. It also handles amplified instruments well. -A true allround microphone!
It's suitable for professional studio and PA use, with a pricetag at the hobbyist level!

It's very small size (about the same as a normal XLR plug) makes it easy to place, without being in the way. Its size and black colour makes it close to invisible on stage. Delivered with foam windsheild and microphone holder (clip).

During manufacturing each capsule is measured, selected and trimmed by us to close tolerances. Out of range capsules are rejected. This in combination with the internal circuitry, results in a response with a unique flatness. These are quality microphones made for demanding situations.

CM3 - really THAT good?

Just a quick thought. Cm3 pair, in NOS, 10’ up and about 3’ back from conductor podium, with one OM1 as a third channel to capture deep bass and mixed in post, was a darn miracle. Sounds fantastic. Nice wide stereo spread, and bass is deep. Mics are ridiculously good for their price.

Rode NT5 vs Line Audio vs sE Electronics sE7 for church bells recording

As promised, I offer for comparison two broadcasts of bell ringing concerts. One uses Rode NT5 (cardioid) microphones, the other uses Line Audio CM3 (cardioid). What sound do you like best? You can compare by the first - Intercession - ringing (there are timestamps in the video description). 1. 2.
