Thank you for choosing Senal. Senal’s CX-series Professional Boundary Microphones are sleek, low-profile microphones that are designed for capturing voices. Both omnidirectional and cardioid models are perfect for video conferences, lectures, and meetings. The CX-series microphones integrate into most AV conferencing systems or sound systems. Balanced output minimizes unwanted RF interference and noise, even over long cable runs, and a high-pass filter minimizes room noise and low-end rumble.

Setting Up To set up your room with omnidirectional or cardioid CX microphones, refer to the illustrations below. Cardioid Polar Pattern LED CXBM-620 MUTE The CXBM-620/C rejects off-axis noise. Use it in rooms with inadequate acoustic treatment or in spaces where background noise is problematic. The CXBM-620/C will capture the voice of the person sitting directly in front of it while it minimizes room noise and reverberation.

When integrating the CX Boundary Mic into a video or audio conferencing system, or using it with a mixing board, make sure that phantom power is enabled.
