Product Overview
The Bose® FreeSpace® 4400 business music system is an
integrated four-zone system providing signal processing,
routing and amplification for installed business music
applications. The system delivers lifelike music and
intelligible pages in up to four separate areas. System setup
and configuration are accomplished using a PC and the
included FreeSpace 4400 Installer™ software.
Product Information
The FreeSpace 4400 business music system has five audio
inputs – two dedicated line-level inputs, one mic/line input,
one page/mic/line input and one dedicated direct input. The
line-level inputs feature dual RCA jacks, and the mic/line
input features a 3-pin Euroblock connector. The page/mic/
line and the direct inputs feature 4-pin Euroblock connectors
for PTT (push-to-talk) capability.
Onboard DSP provides routing and signal processing for
up to four output zones. Any input source may be assigned
to any of the four output zones. Each output zone supports
Auto Volume, Dynamic Equalization, Room EQ, Bose
Loudspeaker EQ and Output Gain functions.
A proprietary Power Sharing amplifier distributes up to 400
watts of system power across the four output zones. Each
output zone may draw as little as 1 watt of power up to as
much as 400 watts. The amount of power delivered to an
output zone is dependent on the quantity and transformer
tap setting of loudspeakers that are connected. The amplifier
can be configured for either 70 V or 100 V constant voltage
systems.
Wall-mounted AVM (Auto Volume/Mute) or Page user
interfaces allow for easy control of system functions such as
paging, volume and source selection, allowing the owner to
control system operation.
FreeSpace 4400 Installer™ software is included with
the FreeSpace 4400 business music system and allows
designers and installers to create project files for the setup,
configuration and servicing of FreeSpace 4400 business
music systems.
