For background/foreground music and paging applications, the Bose FreeSpace IZA 250-LZ integrated zone Low Impedance 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.
For background/foreground music and paging applications, the Bose FreeSpace IZA 250-LZ integrated zone Low Impedance 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 DS 16 and DS 40 loudspeakers, even further sound optimization is possible through onboard selectable EQ presets.
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 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
Easy connectivity and expansion are possible for applications where a second set of output channels are required. An auxiliary line output is provided to share signals with an optional FreeSpace ZA 250-LZ or ZA 190-HZ
