For background/foreground music and paging applications, the Bose Professional FreeSpace IZA 250-LZ and IZA 190-HZ integrated zone amplifiers are designed to deliver premium sound, provide simplified setup and easy daily operation, and offer the flexibility to expand when more loudspeakers are required. When used with FreeSpace FS2 and FS4 loudspeakers, even further sound optimization is possible through onboard selectable EQ presets.
