BOSE / FreeSpace ZA190-HZ

A high-impedance compact power amplifier that can be easily expanded in combination with an Integrated Zone Amplifier.

■Extension power amplifier for IZA190-HZ
■Please note that the ZA190-HZ cannot be used alone.
■High-quality sound design
The compact body employs a reliable digital amplifier and features Automatic Dynamic Equalization, which maintains optimal tonal balance at any volume level. It delivers optimal sound quality without the need for user adjustments.

■Simple installation
Low-impedance compatibility (ZA 250-LZ, 2 x 50W @ 4Ω / 2 x 32W @ 8Ω) is also available, allowing for expansion tailored to your system plan. Simply connect the two amplifiers to the AUX output of the IZA series amplifiers to operate as a single system, allowing you to share sources such as music and paging as well as control the IZA series master volume.

■Compact design
The compact and lightweight 1U half-rack size enclosure can be placed in a variety of locations, such as on a shelf or table, providing flexible installation options. Additionally, the optional Rack Mount Kit accessory allows you to install two amplifiers in a 1U rack.

■Supports a variety of system expansions
The ZA series can be connected to the line output of a DXA2120, FS4400, ControlSpace, or other system and used as a simple standalone amplifier. This allows for flexible expansion even when an additional small amplifier is needed for a small zone in an existing sound system.
