Bose FreeSpace IZA 2120-HZ Integrated Zone Amplifier

Bose FreeSpace IZA 2120-HZ Integrated Zone Amplifier

The Bose FreeSpace IZA 2120-HZ Integrated Zone Amplifier is purpose-built for commercial background and foreground music and paging applications. Optimized for use with Bose FreeSpace and DesignMax loudspeakers, it combines 2 x 120 W of 70/100V Class-D power with onboard DSP, Loudspeaker EQ, Opti-Voice paging, and Dynamic EQ to deliver clear announcements and full, balanced music at any volume level across two independent zones.

• True two-zone design with independent outputs, level, source selection, tone controls, and paging/aux routing
• Opti-Voice paging enhances vocal frequencies for clearer announcements and smooth transitions between music and speech
• Dynamic EQ maintains full and balanced music at low, medium, and high volume levels
• Independent Loudspeaker EQ per output for simple, optimized connection to Bose FreeSpace and DesignMax loudspeakers
• Reliable 2 x 120 W Class-D amplification optimized for 70/100V high-impedance systems
• Support for dual remotes and Bose ControlCenter controllers for flexible, wall-mounted zone volume/source control
• Front-panel controls for input select, tone, and master level plus 3.5 mm aux input for quick connection of mobile devices
• Intuitive, PC-free setup for inputs, outputs, paging priorities, remotes, and Auto-Standby options
• Remote muting capability for integration with centralized control and safety systems
• Compact 1U rackmount chassis with forced-air cooling for dependable commercial operation

Ideal for retail stores, restaurants and bars, hospitality venues, conference centers, schools, and auxiliary zones, the FreeSpace IZA 2120-HZ brings together routing, processing, and amplification in a single, easy-to-use package that elevates everyday audio while simplifying installation and operation.
