BM 404

Desktop Paging Microphone

BM 404 is a desktop paging console that allows making selective calls to 4 zones. Specifically designed as a complement for Business Music systems, such as DMA amplifiers, the console is made of a shock-resistant polymeric body, fitted with an electret microphone on a 230 mm gooseneck, and a polyurethane foam windscreen. Connect up to 4 consoles on a single chain (interlocked) to each amplifier with a CAT5 cable (included). Dedicated buttons with LEDs allow for microphone activation and zone selection. Chime tone is selectable with a single on/off switch. The RCF BM-404 is ready to use out of the box and does not require any configuration.
