Bose Professional FreeSpace IZA 2120-HZ 4x2 FreeSpace Integrated Zone Amplifier

The Bose Professional FreeSpace® IZA amplifiers are optimized for commercial applications, and possess three key features – Loudspeaker EQ for enriching audio quality, Opti-voice® paging for equalizing vocal/speech frequency ranges while providing seamless transitions and Dynamic EQ that ensures full and balanced music at any volume. When paired with FreeSpace® loudspeakers, the Bose Professional IZA 2120-HZ integrated zone amplifier elevates the audio experience of background/foreground music and paging to a higher level.

The amp’s two-zone capability provides two independent outputs that support volume and source selection remotes, EQ, tone controls, and paging/auxiliary routing options. An independent Loudspeaker EQ output enhances audio quality and simplifies connection to Bose Professional loudspeakers – FreeSpace® 3 systems, FS3 subwoofer, DS 16, DS 40 and DS 100 - and has expansion-ready connectivity with FreeSpace® ZA amplifiers to drive additional zones.

Meant for 70/100V high-impedance applications, the unit’s reliable 2x120W Class-D amplification is suitable for retail stores, hospitality venues, conference centers and schools. The amp’s dual remotes support optional volume/source selection for independent (or combined) zone control, and this eliminates the need for bulky, inefficient, and sound-altering 70/100V in-line volume controls.

Remote muting allows for the amp to be muted with a centralized control system, and an intuitive feature setup enables the amplifier to be configured without a PC for remote paging or auxiliary input/output. In addition, an Auto-Standby feature allows the amplifier to consume less power when not in use, and a simplified front panel interface provides tone, source selection and master volume controls, as well as a connection to mobile sources via a 3.5 mm connector.
