A versatile active PA horn specifically designed for vehicle use with a suction mount cup so it can be easily removed from bodywork without damage. The unit can be powered by a 12V supply such as a cigarette lighter socket and when powered up, delivers 25W of power. A detachable handset provides the user with a 'push to talk' button microphone and also houses a USB and SD card reader for playback of media files as well as a 3.5mm jack for connecting any generic MP3 device such and an iPod or iPhone/tablet. A built-in record function allows speech of up to 120 seconds to be stored and played back via a clever loop function. This unit also provides alarm and siren sounds for emergencies and alerting the public.
