Bose Professional Now Shipping Four New Models in Expanded FreeSpace Amplifier Line

Bose Professional is now shipping four new dual-channel amplifier models from its broadened FreeSpace amplifier line. These models are optimised for premium commercial applications and work well with Bose Freespace loudspeakers.

Bose said the new amplifiers offer high-quality amplification (2 x 120 W) for either high- or low-impedance applications, allowing system integrators to spec FreeSpace amplifiers and loudspeakers in a wider range of venues. There are two mixer amplifiers (IZA 2120-HZ, IZA 2120-LZ) and two expansion amplifiers (ZA 2120-HZ, ZA 2120-LZ).

FreeSpace amplifiers can be quickly configured without the use of a PC, enabling each installation to be customized. The IZA models include an integrated audio DSP providing Bose loudspeaker EQ, Bose Dynamic EQ, Opti-voice paging/ducking, audio mixing/routing, bass/treble adjustments, remote control options and an auto standby feature.

The ZA models support sound system expansion when using front-end Bose products such as FreeSpace integrated zone amplifiers and ControlSpace engineered sound processors.

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.

Additionally, the IZA 2120-HZ offers true two-zone capability, providing two independent outputs that each support volume/source selection remotes, EQ, tone controls and paging/auxiliary routing options.


Bose FreeSpace zone amplifiers are designed to provide basic amplification and sound system expansion when using front-end Bose products, such as FreeSpace integrated zone amplifiers and ControlSpace engineered sound processors. ZA zone amplifiers offer excellent audio quality from a reliable, high-quality Class-D amplifier.

When connected to an IZA integrated zone amplifier, the ZA zone amplifier allows for easy system expansion. Chained amplifiers will function together as a single expanded system, sharing the same music, paging sources, master volume control and optional loudspeaker equalization. Each ZA zone amplifier comes in a compact, lightweight design for uncomplicated installation in a range of locations.
