Bose FreeSpace IZA2120LZ Integrated Zone Amplifier MASTER EU

For background/foreground music and paging applications, Bose® FreeSpace® IZA 2120-LZ integrated zone amplifier elevates the audio experience when using FreeSpace® loudspeakers. Optimized for commercial applications, 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.


  • Opti-voice® paging equalizes the vocal frequency range for clear speech intelligibility while providing seamless transitions
  • Dynamic EQ ensures full and balanced music at any volume level
  • Independent Loudspeaker EQ per output enriches audio quality and simplifies connection to Bose® loudspeakers: FreeSpace® 3 systems, FS3 subwoofer, DS 16, DS 40 and DS 100
  • Remote option for volume/source selection eliminates the need for bulky, inefficient, and sound-altering in-line volume controls
  • Dual remotes support optional volume/source selection 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 ZA amplifiers to drive additional zones
  • Reliable 2 x 120 W Class-D amplification optimized for low-impedance applications
  • Intuitive feature setup enables the amplifier to be configured without a PC for output, remote, paging, auxiliary input/output and automatic standby options
  • Auto-Standby feature allows the amplifier to consume less power when not in use
  • Simplified front panel interface provides end users with tone, source selection and master volume controls as well as a connection to mobile sources via a 3.5 mm connector
  • Remote muting allows the amplifier to be muted via a centralized control system
