Even in the compact, lightweight version, the devices have all the important features for a wide range of applications. With the range of reliable megaphones, there is the optimal solution for every area of application. A few basic decision criteria will help you choose the right device. The range is certainly the most important criterion. Here, the greater the sound pressure (in dB), the greater the range of the megaphone. You can also choose between megaphones with an integrated microphone, with a handheld microphone or devices with an additional radio microphone. All megaphones of the MONACOR brand are powered by standard batteries. As an alternative, some devices offer the additional option of a 12 V connection. Size, weight and the power consumption are further deciding factors.
