For background/foreground music and paging applications, Bose Professional FreeSpace IZA 2120-HZ 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.
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 simplifies connection to Bose Professional loudspeakers: FreeSpace 3 systems, FS3 subwoofer, FS2, FS4 and DesignMax DM2
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
Reliable 2 × 120 W Class-D amplification optimized for 70/100V high-impedance applications
Intuitive feature setup enables the amplifier to be configured without a PC for 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
