The microphone Integrated Circuit design uses the latest technology to provide the lowest noise and highest EMI protection.

2 Microphones are categorized into single omni directional micro-phones and single directional Microphones . The omni directional Microphones accept sound from all around the perimeter while directional micro-phones reject sound from certain directions. The directional Microphones are best used for an applica-WLRQ ZKHUH XQZDQWHG VRXQG QHHGV WR EH OWHUHG RXW 6 RQLRQ R HUV WKH PLFURSKRQHV ZLWK WKH EHVW SHU-IRUPLQJ 'LUHFWLRQDOLW\ ,QGH[ 6 RQLRQ DOVR SURYLGHV PRGXOHV ZKHUH ERWK RPQL DQG GLUHFWLRQDO PLFURSKRQHV DUH JURXSHG WR SURYLGH D VZLWFKDEOH SDFNDJH WR VXSSRUW GL HUHQW HQYLURQPHQWV Depending on the design, we can accommodate a vast range of spouts and port locations.
