Sennheiser LSP 500 Pro Active Speaker System

The Sennheiser LSP500 is a complete package. It combines a high-end active loudspeaker system with a Sennheiser radio mic receiver in one integrated unit. It can manage up to 3 wireless microphones, bluetooth streaming, and USB all in one unit, as well as a standard mic/line connection. It is also battery powered and can run for up to 6 hours on 2 NP-1 style batteries (included). The wireless capability, combined with the battery power, means that the LSP500 can be run completely wirelessly, without any power or audio cables, making it extremely fast to deploy and unobtrusive.
