More info


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.


Premium sound quality from a reliable, high quality Class-D amplifier designed to expand sound systems for loudspeaker installations

Expandable amplification allows for easy system expansion when coupled with a FreeSpace IZA 250-LZ integrated zone amplifier. The two amplifiers will function together as one system

Compact, lightweight design enables the FreeSpace zone amplifier to be placed out of the way—on a table, desk, counter, shelf or in an equipment rack using the optional Rack Mount Kit accessory

Two models available, 4/8 Ω or 70/100 V output, allow for better fit options for specific installations
