The Classis BM 52 is a very versatile condenser boundary microphone with many different useful functions. Depending on the application, you can choose between the operating modes ON/OFF, Push-To-Talk (PTT) and Push-To-Mute (PTM). In order to suppress low frequency noise, the frequency response can be tailored for use with a two-stage bass roll off filter. The Classis BM 52 is operated with a silent membrane key with braille inscription. An LED indicates the ready-to-speak status. The robust housing with a high-quality design is covered with a very exclusive, dust repellent fabric. Due to its matt, non-glare surface, the Classis BM 52 can discretely be integrated into each installation. It has all possibilities of an intelligent desktop microphone unit. It can be used anywhere, where little space is available, but a high functionality is required. It is ideal for round table discussions, tele/video conferences or distance learning. The increase of the sound pressure at a boundary results in a higher gain, signal-to-noise ratio and comb filter effects cannot occur.
