The rear panel features a USB and SD player, as well as having a 3.5mm aux port, which all allow you to play music or pre-recorded messages. And when you need to get people’s attention or raise the alarm, you can use the Whistle and Siren buttons to emit loud alarms.

There is also a hard-wired microphone, on an extendable cable, which allows you to deliver messages with clear precision, and can be securely fitted to the unit when not in use. Plus, you can also connect your own microphone via the 6.3mm mic input.

With a shoulder strap included, this can be slung over the shoulder and taken with ease wherever you go. The 45W Megaphone can also be mounted on a stand with an 8mm threaded socket or left freestanding on a flat surface.

The 45W Megaphone, manufactured for Vigil Products, is easy to use and is bound to get you heard without having to strain your voice. You can either power this with 10 x D batteries (available to order separately) or an external 12Vdc power cable (not included).
