Bose® FreeSpace® ZA 250-LZ and ZA 190-HZ zone amplifiers are designed to provide basic amplification and sound system expansion when using front-end signal processing from products such as the FreeSpace IZA 250-LZ / IZA 190-HZ integrated zone amplifiers, the FreeSpace 4400 business music system and ControlSpace® engineered sound processors.
