BL CCM 3

Description

This special version of the CCM 2XS L compact microphone is equipped with a flange enabling it to be built into the surface of a table or speaker's rostrum. This makes the microphone nearly invisible, and at the same time improves the sound quality by eliminating comb filter effects.

Practice

The BL CCM 3 is often used as a redundancy microphone in speaker tables.

Product History

• 1994: Launch of the CCM, hybrid technology circuit. The capsule part is identical to the MK capsules from the beginning  
• 2016: better RF filter to protect from interferences
• 2017: Polarization voltage generator now with higher frequency above 200 kHz due to downpitching in sound design applications.
