FreeSpace® 4400
Business Music System
The Bose® FreeSpace® 4400 business music system
is an integrated four-zone system providing signal
processing, routing and amplification for business
music applications.
System setup and configuration are accomplished using the included FreeSpace 4400
InstallerTM software.
FreeSpace 4400 system AVM (Auto Volume/Mute)
or Page user interfaces allow the owner to
control system operation.
Product Information
In a single component, the FreeSpace 4400
business music system provides processing,
control functions and up to 400W of system
power for most business music applications
requiring one to four zones.
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 400W of system power across the four
output zones. Each output zone may draw as
little as 1W of power up to as much as 400W.
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 70V or 100V constant voltage systems.
FreeSpace 4400 Installer software is included
with the FreeSpace 4400 business music system.
Used for the setup and configuration of the
system, the FreeSpace 4400 Installer software
requires a PC for operation.

Key Features
• Proprietary Power Sharing amplifier dynamically
distributes 400W of system power across the
four output zones.
• Auto Volume offers automatic control of
individual zone volume. Volume levels are
adjusted to compensate for changes in background noise, according to the system settings.
• Each output zone may be independently paged.
TECHNICAL DATA SHEET
Product Overview
• Opti-voice® paging provides a smooth transition
between the music and page signals.
• Opti-source® level management monitors the
input level of up to four sources. Source levels
are continually adjusted to maintain a consistent
volume level among different sources.
• Scheduling allows system ON/OFF, zone volume,
mute, Auto Volume and source change events
to be programmed. Up to 64 events may be
programmed to occur on specific days and times.
Applications
The FreeSpace 4400 business music system is
engineered for business music applications
requiring up to four system zones, such as:
• Restaurants
• Supermarkets
• Retail stores
• Shopping centers
• Hospitality venues
• Conference
centers

1. Amplifier power
EIA Power – With the amplifier operating in 70V
or 100V mode, a single channel is driven to full
power with the minimum load impedance. Output
power is measured using a 1 kHz sine wave with
1% THD, as measured at the amplifier output.
TECHNICAL DATA SHEET
Safety and Regulatory Compliance
FTC Continuous – With the amplifier operating
in 70V mode, any combination of channels are
driven to full power with the minimum load
impedance. Output power is measured using test
signals between 20 Hz and 12 kHz with 1% THD,
as measured at the amplifier output.
2. Signal-to-noise ratio
The output of the amplifier is connected to
the rated load impedance with a unity gain of
a frequency of 1 kHz. A dB-calibrated voltmeter
is connected to the amplifier’s output through
an A-weighting filter (in accordance with IEC
60651). A 1 kHz signal is connected to one of
the line inputs, and the level is adjusted to achieve
the amplifier’s rated output power. The signal
source is removed, and the line input is shorted.
The dB-calibrated voltmeter now reads the
A-weighted output noise level.
