Line Audio CM4 Cardioid Condenser Microphone

The CM4 has superseded the CM3 which is now discontinued. Introducing the CM4! 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 linear off axis performance is beneficial with large sound sources and for stereo recording, preserving sound character at an angle.

The CM4 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 all-round microphone!

It's suitable for professional studio and PA use, with a price tag 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 windshield and microphone holder (clip).

During manufacturing each capsule is measured, selected, and modified 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.

Fantastic souning mic and fabulous value for money!
Friday, 19 June 2020  | 

The Line Audio CM4 is a really great, really natural sounding small diaphragm condenser microphone, as such it is very versatile. I bought a pair to use as over heads, but have found them being used for all sorts of applications. I have also used the CM4 for classical music recording and they sound great there too. So if you are looking for a general purpose work horse SDC that compares cery favourably with mics costing up to 10 times the price then the Line Audio CM4 is very well worth considering!
Fantastic service and very speedy delivery from Pinknoise Systems! Thanks so much!

This mic is superb, I bought it on recommendation (apparently you won't get better at this price-point) and was not disappointed!
