Adastra L50U megaphone with USB & SD MP3 media player

A large 50Wmax megaphone with 340mm spun aluminium flare and carrying handle. Can be operated free standing on rear legs or shoulder slung with the included strap. Alternatively, the megaphone can be mounted onto a stand via an 8mm threaded socket in the top of the flare. The rear panel is home to a USB/SD player with 3.5mm aux input and a latched cover for the battery compartment. 3 latching buttons control on/off, USB/SD and siren buttons and a non-latching button controls the whistle, all governed by a rotary volume control. A hard-wired clip microphone is provided with talk button and volume control or alternatively, a separate microphone can be connected to the 6.3mm mic. input. The most important feature is the power output, which can project sound as far as 1.5km, making this a serious product for announcements, event management and crowd control.
