The TM-90BM is an affordable boundary condenser microphone for applications where multiple speakers or other sound sources are to be miked on an equal basis.
It is ideally suited for personal broadcasting, reinforcement of conferences or stage plays or ambience miking, for instance.
Compared to miking with several microphones, using a boundary mic has several advantages like higher sensitivity, less tone colouration, an unobstructed view, less “microphone fright” and more.
Make sure you place this mic on a large, hard surface such as a table, hard panel or floor to fully benefit of the boundary microphone principle and to obtain a rich sound (the larger the surface, the better the low frequency response).
