Bose FreeSpace ZA 250-LZ Zone Amplifier (Discontinued)

Description

Details

The Bose® FreeSpace® ZA 250-LZ zone amplifier provides basic amplification and sound system expansion for use with front-end signal processing devices. Expansion is simplified when this amplifier is used with a FreeSpace IZA integrated zone amplifier, where one cable connection allows the amplifiers to function together as one system—sharing music and paging sources, as well as master volume control. You can also use the FreeSpace ZA amplifier with other products, such as the Bose FreeSpace 4400 business music system and ControlSpace® engineered sound processors, to provide amplification for additional zones.

Features

Features

Premium sound quality from a reliable, high quality Class-D amplifier designed to expand sound systems for loudspeaker installations
Expandable amplification allows for easy system expansion when coupled with a FreeSpace IZA 250-LZ or IZA 190-HZ integrated zone amplifier. The two amplifiers will function together as one system
Compact, lightweight design enables the FreeSpace 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
Two models available, 4/8 Ω or 70/100V output, allow for better fit options for specific installations
