Bose Professional FreeSpace IZA 2120-HZ Zone Amplifier

The Bose 719782-1430 is a FreeSpace IZA 2120-HZ zone amplifier built for stores, restaurants, conference rooms, and any other venue that needs dependable music playback and paging. It provides two 120 watt channels that power 70 or 100 volt loudspeaker lines, so you can run long cables and multiple speakers without signal loss.

The unit supports two independent zones, giving staff the ability to set different volumes, equalization, and audio sources in each area. Background music can stay subtle in a dining room while an adjacent bar can run a louder playlist, all from one chassis.

Opti-Voice paging automatically ducks the music when a microphone signal comes in, allowing announcements to sound clear without manual adjustment. As soon as the page finishes, Dynamic EQ restores the music’s tonal balance so the listening experience stays consistent at any volume.

Installation crews will appreciate the straightforward front panel with dedicated controls for master volume and tone. The amplifier fits a single rack unit, includes fan cooling, and enters Auto-Standby when no signal is present, which helps commercial sites meet energy guidelines.

Balanced, unbalanced, and dedicated paging inputs make the amplifier flexible during system design, and the built-in loudspeaker equalization matches FreeSpace and DesignMax loudspeakers out of the box. Protection circuits guard against short circuits, overvoltage, and thermal overload to keep the system running day after day.
