The Dynacord PM502 is a great powered mixer to hire which can power standard speakers and also has a 100V option. The mixer has 8 channels, 5 XLR inputs and 3 stereo line in, built in FX and compression. For music or audio playback you can plug in a USB drive into the unit or through a mini jack cable (supplied) into one of the stereo line inputs. Having the built in amplifier means that there is less to set up allowing for quicker set up time and the mixer can sit discreetly somewhere without taking up much space.
