Bose® FreeSpace® IZA 2120-HZ integrated zone amplifier elevates the audio experience

- for background/foreground music and paging applications, when using FreeSpace® loudspeakers.

Optimized for commercial applications, FreeSpace IZA amplifiers feature selectable Loudspeaker EQ to enrich audio quality, Opti-voice® paging for clear speech intelligibility while providing seamless transitions and Dynamic EQ that ensures full and balanced music at any volume level.




True two-zone capability provides two independent outputs that each support volume/source selection remotes, EQ, tone controls, and paging/auxiliary routing options 

Opti-voice® paging equalizes the vocal frequency range for clear speech intelligibility while providing seamless transitions 

Dynamic EQ ensures full and balanced music at any volume level

Independent Loudspeaker EQ per output enriches audio quality and simplifies connection to Bose® loudspeakers: FreeSpace® 3 systems, FS3 subwoofer, FS2, FS4 and DesignMax DM2

Reliable 2 x 120 W Class-D amplification optimized for 70/100V high-impedance applications

Intuitive feature setup enables the amplifier to be configured without a PC for remote, paging, auxiliary input/output and automatic standby options
