It is essentially a small stereo PA, styled to look somewhat like a ghetto blaster, and it can run from the included mains supply (a universal–voltage external PSU) or batteries (eight D cells or optional lithium battery pack), making it ideal for up–market busking or general indoor use where extreme volumes are not required. Mackie’s FreePlay adds to the range of multi–purpose portable amplifiers that seems to have carved a significant market niche over the past few years. Need a go–anywhere sound system for busking, small gigs or simply listening to music on the move? Look no further!
