Bosch Dynamic Normally open Low Z Handheld paging microphone - 450D

Bosch 450D Concise Descriptor

Overview

The Bosch 450D is a dynamic, low impedance, normally open handheld paging microphone designed for clear voice announcements in public address and voice alarm systems. Its robust construction and straightforward operation make it suitable for environments requiring reliable, on-demand communication, such as retail environments, public transport hubs, or industrial facilities where quick announcements are critical. The 450D model ensures your voice is heard distinctly over background noise.

Compatibility

This microphone is designed for use with Bosch public address and voice alarm system amplifiers and matrix mixers that feature standard microphone inputs. It is compatible with systems requiring a low impedance microphone with a normally open contact for push-to-talk functionality. Specific compatibility should be verified against the input requirements of your Bosch amplifier or mixer model.

Installation Notes

The Bosch 450D utilizes a standard XLR connector for audio output. The integrated push-to-talk button is a normally open switch, meaning it completes the circuit only when pressed, allowing for simple integration into zone selection or activation circuits within compatible Bosch systems. No external power is required for the microphone element itself, as it is powered by the connected amplifier or mixer.
