Application Info

The Lunchbox 660 is an all-purpose battery-powered mixer/amplifier designed to work with any passive speakers you already have. Or may we recommend our Lunchbox Speakers. The Lunchbox is perfect for outdoor gatherings or ceremonies (weddings, funerals, school assemblies) where you need to address groups of up to 500, and play music at moderate levels. Five dual-purpose inputs let you connect almost any combination of microphones, instruments, and CD/tape player.
