Product Description

®
The Bose FreeSpace
Mixer/Amplifier integrates digital signal
processing with two 120-watt output
channels. Designed as a mixer/router for
business music applications, it features
an LCD panel and control buttons behind the front cover for ready access and easy configura-
tion.
The mixer/amplifier provides six inputs, including 4 Mic/Line inputs, 1 Page input, and 1 Direct
input. The Direct input can override all sources playing on the output channels. Each Mic/Line
input provides both RCA and Euroblock jacks. The Euroblock connectors will accept either a Mic
or Line level input. The RCA jacks accept Line level inputs only.
Two output channels are wired for 120 watts at 4 ohms each. For 70/100 volt applications, a
jumper is required for proper configuration. In 70/100V applications, the two outputs will operate
at 100 watts per channel. A third output is available for an auxiliary line out.
Additional features include:
• Signal Mixing: In Mixer Mode, simultaneously combines up to four inputs for any of the
three outputs.
•
Signal Routing: In Dual Mono Select Mode, one or two inputs go to each of two outputs in
different zones and can be remotely selected. Or in Stereo Select Mode, two stereo sources
go to one output zone and can be remotely selected.
