TECHNICAL DATA SHEET
Product Description
For background/foreground music and paging applications, Bose®
FreeSpace® IZA 2120-HZ integrated zone amplier elevates the audio
experience when using FreeSpace® loudspeakers. Optimized for
commercial applications, FreeSpace IZA ampliers 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.
Key Features
• True two-zone capability provides two independent outputs that
each support volume/source selection remotes, EQ, tone controls,
and paging/auxiliary routing options.
• 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 simplies connection to Bose® loudspeakers: FreeSpace® 3
systems, FS3 subwoofer, DS 16, DS 40 and DS 100.
• Dual remotes support optional volume/source selection for
independent, or combined, zone control which eliminates the need for
bulky, inefcient, and sound-altering 70/100V in-line volume controls.
• Expansion-ready connectivity with FreeSpace ZA ampliers to drive
additional zones.
• Reliable 2 x 120 W Class-D amplication optimized for 70/100V
high-impedance applications.
• Intuitive feature setup enables the amplier to be congured without
a PC for remote, paging, auxiliary input/output and automatic standby
options.
• Auto-Standby feature allows the amplier to consume less power
when not in use.
• Simplied 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 amplier to be muted via a centralized
control system.
Applications
