D 542 ST-S “plug & play” paging station

The D 542 ST-S for crystal-clear announcements!

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.
