Bose AMPLIFIER, ZA 190-HIGH Z,230V EU SLAVE 1 x 90 Watts

Description

The Bose® FreeSpace® ZA 250-LZ / ZA 190-HZ 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.

Key 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 70/100 V output, allow for
better fit options for specific installations

Applications

Designed for a wide range of applications, including:
• Retail stores
• Restaurants and bars
• Hospitality venues
• Conference centers
• Schools
• Auxiliary zones
