IZA 250-LZ

FreeSpace

Overview

For background/foreground music and paging applications, the Bose Professional FreeSpace IZA 250-LZ and IZA 190-HZ integrated zone amplifiers are designed to deliver premium sound, provide simplified set up and easy daily operation, and offer the flexibility to expand when more loudspeakers are required. When used with FreeSpace FS2 and FS4 loudspeakers, even further sound optimization is possible through onboard selectable EQ presets.

Features

  • Amplification for premium sound from a reliable, high quality Class-D amplifier provides optimized performance and premium sound quality through the use of internal digital signal processing

  • Installation made simple with set up done locally from the front and rear panels of the amplifier—no computer is required

  • Opti-Voice paging provides smooth automatic transition between the music and page signals

  • End-user friendly front panel allows users to connect devices easily, make tonal adjustments or select between two sources. Optional wall mountable Bose Professional Volume control with A/B switch user interface allows volume and source selection controls to be placed away from the amplifier for user convenience

  • Compact, lightweight design enables the FreeSpace integrated zone amplifier to be placed out of the way—on a table, desk, counter, shelf or in an equipment rack using the optional Rack Mount Kit accessory
