Introduction

Product Overview

This guide provides installation and operating information for FreeSpace® IZA 2120-LZ / IZA 2120-HZ
integrated zone amplifiers and ZA 2120-LZA / ZA 2120-HZA zone amplifiers.
FreeSpace® IZA 2120-LZ / IZA 2120-HZ Integrated Zone Amplifier
The FreeSpace® IZA 2120-LZ / IZA 2120-HZ integrated zone amplifier provides signal processing, routing,
paging, zoning and amplification for a wide range of commercial applications such as retail stores,
restaurants and bars, hospitality venues, conference rooms, schools and auxiliary zones.
The integrated zone amplifier offers a variety of input connections (mic/line/page), input gain and output
level adjustments, and operational modes. Built-in Bose® FreeSpace FS3/HPF, DS 16, DS 40, DS 100, FS3B,
and RoomMatch® Utility RMU105 loudspeaker EQ presets can be selected for loudspeaker optimization.
FreeSpace® ZA 2120-LZA / ZA 2120-HZA Zone Amplifier
The FreeSpace ZA 2120-LZA / ZA 2120-HZA zone amplifier makes system expansion easy. Simply connect
the auxiliary output of an IZA integrated zone amplifier to the input of a ZA zone amplifier. The two
amplifiers will function together as one system sharing the same music, paging sources, master volume
control and optional loudspeaker equalization.
ZA zone amplifiers are designed to expand sound systems that utilize front end signal processing from
products such as the Bose FreeSpace® IZA 2120-LZ, IZA 2120-HZ, IZA 250-LZ and IZA 190-HZ integrated
zone amplifiers and Bose ControlSpace® engineered sound processors. With the inclusion of AmpLink,
up to the first 8 digital audio channels can be sent to the amplifier from a Bose DSP via a shielded CAT 5
cable. The FreeSpace ZA 2120-LZA / ZA 2120-HZA zone amplifiers can also be used as stand-alone
amplifiers from any balanced or unbalanced line-level source.
