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.


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