More info


The Bose® FreeSpace® ZA 2120-HZ zone amplifier is 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.


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

Dual remotes support optional volume adjustment for independent, or combined, zone control which eliminates the need for bulky, inefficient, and sound-altering 70/100V in-line volume controls

Expansion-ready connectivity with FreeSpace® IZA amplifiers when additional sources and loudspeaker processing is required

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

Auto-Standby feature allows the amplifier to consume less power when not in use

Remote muting allows the amplifier to be muted via a centralized control system
