A high powered active speakers series identical in performance and construction to the unpowered units, each include a self-contained power amplifier. Simply connect 240VAC power and an input source such as a CD player, tape deck or microphone and you have a crystal clear, high powered PA system! It features 2 x XLR microphone inputs. Microphone one input can be either balanced XLR or balanced 6.35mm. A single 6.35mm line input which can be switched between the USB/MP3 player is also available. It also has an XLR line out connector, allowing multiple powered speakers to be ‘daisy chained’ from a single input source. Using two of these units connected together to one microphone, you could easily address a crowd of 1000 people! The power amp has separate volume controls for mic input, line input and master output, plus bass and treble controls. This model also features a built-in USB MP3 player module with a digital LCD display for track information.
