The BLM-21 is a boundary layer microphone which uses the same capsule as the RCM-402. Due to the pressure zone technique the noise level is 6dB lower than the RCM-402. The HF roll-off from 10kHz is also due to the boundary layer principle. The microphone is particularly suitable for surround rear”channels. It uses 60V powering to give very high SPL performance.
