The Bose® FreeSpace® ZA 250-LZ zone amplifier provides basic amplification and sound system expansion for use with front-end signal processing devices. Expansion is simplified when this amplifier is used with a FreeSpace IZA integrated zone amplifier, where one cable connection allows the amplifiers to function together as one system—sharing music and paging sources, as well as master volume control. You can also use the FreeSpace ZA amplifier with other products, such as the Bose FreeSpace 4400 business music system and ControlSpace® engineered sound processors, to provide amplification for additional zones.
