SE ELECTRONICS sE BL8 Surface-mounted Microphone

The SE ELECTRONICS sE BL8 is a professional surface-mounted condenser microphone designed for high-quality audio capture in conferencing, boardrooms, and installed sound applications. Featuring a small-diaphragm electret condenser capsule (sE8 capsule) with a cardioid polar pattern, it delivers exceptional clarity and off-axis rejection. The all-metal chassis ensures durability and RF rejection, while switchable pads (-10 dB / -20 dB) and low-cut filters (80 Hz / 160 Hz) provide versatile control for various acoustic environments.

Advantages

With a frequency response of 20 Hz - 20 kHz, sensitivity of 25 mV/Pa, and a maximum SPL of 148 dB, the BL8 captures subtle nuances and handles high sound pressure levels without distortion. Its low self-noise (14 dB-A) and high signal-to-noise ratio (80 dB) make it ideal for critical listening and speech reinforcement. The switchable pad and low-cut filter allow quick adaptation to different sources and room conditions.
