Bosch Audio 450D Handheld Dynamic Paging Microphone

Product Description

The BOSCH AUDIO 450D is a handheld dynamic microphone designed for paging and public address applications. Dynamic microphones of this type use a moving-coil transducer to convert sound into an electrical signal, making them durable and well-suited for demanding commercial and institutional environments. The 450D is a wired handheld unit intended for integration into paging systems where reliable voice intelligibility is the primary requirement. Audio-visual technicians and low-voltage system integrators are the typical trades that source and install this type of microphone.

The 450D fits standard paging and intercom system setups found in commercial buildings, schools, healthcare facilities, warehouses, and light industrial environments. It is used at front-desk stations, dispatch consoles, and central paging points where an operator needs a handheld mic connected directly to a paging amplifier or intercom controller. The wired design eliminates battery dependency and RF interference concerns common with wireless alternatives.

Installation Notes

Installation is typically performed by a licensed low-voltage technician or audio-visual systems integrator. Power down or mute the paging amplifier before connecting or disconnecting the microphone to avoid transient noise spikes that can damage speaker components. Verify the input impedance of the receiving amplifier matches the output impedance of the microphone before finalizing the connection. Follow all applicable local and national codes governing low-voltage signal wiring.
