Bose Professional FREESPACE ZA Overview

  • 1Description

The Bose Professional FreeSpace ZA 2120-HZA is a 70/100V high-impedance zone amplifier for background/foreground music and paging well suited for business music applications including conference spaces, retail stores, hotels, lobbies, bars, and restaurants. The amplifier provides basic amplification and sound system expansion when using optional front-end Bose products such as FreeSpace IZA 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 cable. The FreeSpace ZA 2120-HZA ships with several Euroblock connectors, a stereo RCA cable, and a standard IEC power cord.

  • Reliable 2 x 120 W Class-D amplification optimized for 70/100V high-impedance applications
  • AmpLink transports up to 8 uncompressed, near zero-latency, digital audio channels between Bose DSPs and the ZA 2120-LZA via shielded Cat 5 cable. The amp also supports a thru path for daisy-chaining digital audio to other Bose AmpLink products at 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 are required
  • Intuitive feature setup enables the amplifier to be configured without a PC for 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
