Beyerdynamic Classis BM 42 BC Boundary Microphone XLR

Deskripsi Produk

The Classis BM 42 is a small condenser boundary microphone with a semi-cardioid polar pattern. The robust housing is of a high quality design and covered with a very exclusive, dust repellent fabric. Due to the linear frequency response the microphone can be used for a number of applications, for which a microphone mounted on a stand cannot be used. The matte, non-glare surface allows integrating the Classis BM 42 discretely into each installation placing the microphone on conference tables, lecterns, round tables or on altars. It also can be used on theatre stages or for live recordings. The integrated high pass filter reduces low-frequency noise from tables and other.

The principle of a directional boundary microphone has several advantages:

• The semi-cardioid polar pattern of the Classis BM 42 provides in contrast to standard boundary microphones a better gain-before feedback and reduces ambient noise
• The increase of the sound pressure at a boundary results in a higher gain, signal-to-noise ratio and comb filter effects cannot occur

The Classis BM 42 is available in matte black or white.
