The D 542 ST-S has been designed for paging and PA systems at airports, in supermarkets,  
and other noisy places. A cardioid dynamic microphone capsule provides a speech-  
optimized frequency response and high rejection of ambient noise to ensure optimum  
intelligibility even in very noisy environments. With its permanently attached coiled cable,  
the D 542 ST-S is ready for connecting to any sound system with XLR microphone inputs,  
and the intuitive ON/OFF switch is very easy to use.
