About the Bose® FreeSpace® IZA 2120-HZ

The hub for a multi-zone Bose commercial sound system

Drive your Bose commercial speaker system with an amplifier that's made for the job. The FreeSpace IZA 2120-HZ puts out 120 watts per channel, and you can send output to two zones. Auxiliary output lets you connect standalone Bose power amps to drive speakers in additional zones.

It also features multiple input options so you can connect plenty of sources. Opti-voice technology helps balance volume levels when you switch from music to paging, so important announcements can be heard clearly.

Pre-programmed EQ for select Bose speakers

The IZA 2120-HZ uses Class-D amplification for efficient operation and clean sound. And there's built-in equalization for optimizing sound characteristics with specific Bose speaker models, including the FreeSpace 3 subwoofer, DS 16F, DS 16SE, DS 40F, DS 40SE, DS 100F and DS 100SE speakers.
