FreeSpace® ZA 2120-HZA
The Bose® FreeSpace® ZA 2120-HZA 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. With the inclusion of AmpLink, up to 8 digital
audio channels can be sent to the amp from a Bose DSP via a shielded CAT 5
• Reliable 2 x 120 W Class-D amplification optimized for 70/100V high-impedance
• AmpLink transports up to 8 uncompressed, near zero latency, digital audio
channels between Bose DSPs and the ZA 2120-HZA via shielded CAT 5 cable.
The amp also supports a THRU path for daisy-chaining digital audio to other
Bose AmpLink products at a distance of up to 10 m between products.
• 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 and ControlSpace®
engineered sound processors 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
• Remote muting allows the amplifier to be muted via a centralized control system
Designed for a wide range of applications,
• Retail stores
• Restaurants and bars
• Hospitality venues
• Conference centers
• Auxiliary zones
