1.0 FreeSpace® 4400 Introduction
1.1 The Bose® FreeSpace® 4400 Business Music System
The FreeSpace® 4400 system is an integrated four-channel digital
signal processor and 400-watt power amplifier for 70/100V busi
ness music applications.
The FreeSpace 4400 system has a total of four source inputs,
including two Line In, one Mic/Line and one Page/Mic/Line, to
provide the inputs needed for most business music installations.
The system also has a direct input which can override the
sources playing on all four output channels.
The FreeSpace 4400 system has four amplifier output channels
which can be configured for different zones. A Music on Hold out
put is also provided for simple integration into a phone system.
In a single chassis, it provides all of the processing and control
features required for one-to-four zone business music applications. These features include:
• Auto Volume: When used with the optional FreeSpa ce system
Auto Volume Sense Mic, Fre eSpace 4400 system ele ctr onics
dynamically control the program level in each zone so your cus
tomers can always hear it, regardless of the background noise.
• Scheduling: Allows you to program the FreeSpace 4400 sys-
tem electronics for automated on/off control, source changes,
and volume changes according to time of day or day of week.
• Multi-Zone Paging: Allows you to initiate a page from a single
keypad to one or more of the zones being powered by the
same FreeSpace 4400 system.
• Opti-voice® Paging: Provides a smooth transition between
music and page signals.
• Opti-source® Input Leveling: Monitors the input level of up to
four sources and continually makes adjustments to maintain a
consistent volume level between different sources.
• Dynamic Equalization: Maintains tonal balance at all listening
levels.
• Room Equalization: Provides easy adjustment of tonal bal-
ance in each zone.
• Signal Routing: Meets the demands of most four-zone sys-
tems, allowing for an input source to be routed to any of the
four amplifier outputs.
• Serial Data Interface: RS-232 serial port for easy interfacing
to your PC
• Remote On/Off Input: Accepts a remote STANDBY switch
The integrated 400-watt power amplifier features a patented
power-sharing technology which dynamically allocates power to
each output.
For example, if you have a two-zone system that requires 5 watts
in Zone 1 and 395 watts in Zone 2, the FreeSpace 4400 system
electronics distributes the power based on those needs.
The FreeSpace 4400 system also includes an easy-to-replace
memory module, which holds the system configuration settings
and design file uploaded by the FreeSpace 4400 Installer™
software
(see page 3).

2.0 Designing with the FreeSpace® 4400 System
2.1 Introduction
This section describes the basic steps for designing a FreeSpace
4400 system and includes an example. It is assumed that a complete loudspeaker design and layout has already been cr eated.
2.2 Basic design steps
There are five basic steps in designing a FreeSpace 4400 system.
2.2.1 Step 1 – Determine source routing
Decide which sources will be played in each area. Create a
“source map” such as the following one that shows which
sources will be played in each major area of the facility.
Source 1 Source 2 Source 3 Source 4
Area 1 ● ●
Area 2 ● ● ●
Area 3 ● ●
Area 4 ●
Area 5 ●
2.2.2 Step 2 – Determine Auto Volume
requirements
Identify which areas will use Auto Volume. Each Auto Volume
zone must use one AVM (Auto Volume) user interface and one
®
sensing microphone to control the volume.
Bose
When using Auto Volume, remember that you will be adjusting
the volume of an overall area. Imagine that you have a dining area
and a bar adjacent to one another. If the sensing microphone is
placed above the bar, the music may become too loud in the din
ing area. Likewise, if you place the sensing microphone above
the dining area, the music may never be heard in the bar.
Guidelines for establishing Auto Volume zones
Loudspeaker
height is…
>25 ft (7.6 m) Not recommended
12-25 ft
(3.7-7.6 m)
<12 ft (3.7 m) One Auto Volume
Loudspeaker mounting height and the overall quality of the background noise is used to determine the Auto Volume zoning
requirements. Uniform background noise is found in an area
where no part of the area is louder or quieter than any other. A
room with non-uniform background noise would seem louder in
some areas (people talking, machinery running, etc.) and quieter
in others.
Background noise
is uniform
One Auto Volume
zone for every
3600 ft2 (324 m2)
zone for every
1800 ft2 (162 m2)
Background noise
is non-uniform
One Auto Volume
zone for every
1800 ft2 (162 m2)
One Auto Volume
zone for every
900 ft2 (81 m2)
Mounting guidelines for sensing microphones
• The sensing microphone must be mounted at the same height
as the loudspeakers or higher. A sensing microphone must
never be mounted lower than the loudspeaker height.
• In all cases, there must be 6 ft (1.8 m), minimum, between the
loudspeaker and the sensing microphone. This is so that the
microphone does not receive signals only from a loudspeaker.
• There must be 35 ft (10.7 m), minimum, between the sensing
microphones of two adjacent Auto Volume zones.
• Avoid placing the microphone near unique noise sources like
HVAC equipment, dishwashers, motors, etc.
Separating the microphones as much as possible for two zones
is the best practice. Consider the previous example of the dining
area and a bar adjacent to one another. If each of these areas
-
uses Auto Volu me, it is possible to cr eate a situation in th e dinin g
area where the music is too loud simply because the microphone
is too close to the bar.

2.2.3 Step 3 – Determine volume
control requirements
Decide which areas will have volume controls. Create a control
map, such as the following, showing the types of controls that
will be used, and the areas in which they will be installed.
AVM (Auto
Volume)
Interface
1
Area 1 ●
Area 2 ●
Area 3 ●
Area 4 ●
Area 5 ●
AVM (Auto Volume/Mute) user interfaces are available for use
with the FreeSpace
source selection and volume. The interface can be configured as
an AVM (Mute) interface or as an AVM (Auto Volume) interface. If
you have identified an area that uses auto volume, you must con
figure the interface as an AVM (Auto Volume) interface to control
this zone.
It is also possible to use a 70/100V in-line volume control
between the amplifier output and the loudspeaker. If you plan to
use a 70/100V in-line volume control, be aware that they cannot
be used in zones where either Auto Volume or Dynamic EQ is
used. Auto Volume and Dynamic EQ monitor the amplifier output
and make adjustments accordingly. Using an in-line volume con
trol would cause these functions to operate improperly.
When determining the placement or physical location of the controls, first think about how the control is used. If the control is
very rarel y used or it requires a secure location, it should be
placed with the equipment. If the control is for an area that
requires frequ ent adjustmen t s, the n it is best to place th e c on trol
in the area being controlled.

2.2.4 Step 4 – Determine the loudspeaker requirements
Determine the loudspeaker coverage required for the design.
Consider the following points as you do this:
• Each Auto Volume function requires a separate zone. Each
Auto Volume zone requires the dedicated use of one
FreeSpace 4400 output channel.
• Each type of specifically equalized Bose loudspeaker requires
the dedicated use of one FreeSpace 4400 output channel. If
you are designing a system that uses specific Bose loudspeaker equalization, such as the 102®F loudspeaker, Model
32, Model 32SE, or Model 8, you must dedicate one
FreeSpace 4400 output channel for each loudspeaker type.
Create a loudspeaker map, such as the fo llow ing, an d ma tch the
loudspeaker models to areas (Loudspeaker Qty x Tap = Zone
Power required):

2.0 Designing with the FreeSpace® 4400 System
2.2.5 Step 5 – Determine the
FreeSpace
Once you have identified the areas that use Auto Volume and
specifically equalized Bose loudspeakers, you can combine different areas based on the types of sources and controls they are
using.
Now we can take a look at how the maps we created can help us
determine the quantity of FreeSpace 4400s we will need.
Area 1 ● ● ● ● 100 1
Area 2 ● ● ● ● ● 40 2
Area 3 ●● ● ●50 3
Area 4 ● ● ● 12 4
Area 5 ● ● ● 48 4
By combining the maps you can easily combine sources, loudspeaker types, and control types. The information
placed in this table suggests that Area 1 and Ar ea 3 need to be grouped separately because they are Auto Volum e
zones requiring separate FreeSpace 4400 system outputs. Area 2 uses one AVM (Mute) interface requiring one
FreeSpace 4400 output channel. Areas 4 and 5 share a common volume control and can be combined on a third
FreeSpace 4400 output channel. Since only four outputs are required and the total combined power requirement is
less than 400W, only one FreeSpace 4400 unit would be needed for this system.

4.3 Placement guidelines
• Place the FreeSpace 4400 system where it is protected from
heat and allowed adequate ventilation.
• Place the FreeSpace 4400 system away from direct heat
sources, such as heating vents and radiators.
• Make sure that air can circulate freely behind, beside, and
above the chassis for adequate ventilation. There are intake
vents on the sides and an exhaust vent on the back of the unit.
Do not cover or block the vents.
Installer’s Note: Do not allow the chassis to exceed the
maximum operating temperature of 50° C (122° F). Be aware
of conditions in an enclosed rack that may increase the temperature above room-ambient conditions.
4.4 Shelf mounting the FreeSpace
4400 system
The FreeSpace 4400 system is ideal for shelf mounting. The
included accessory kit contains four rubber feet for the bottom of
the FreeSpace 4400 chassis. The rubber feet will protect the sur
face on which the FreeSpace 4400 system is installed and help
prevent movement of the FreeSpace 4400 system. Be sure to follow the “Placement Guidelines” previously described when
choosing a location for the FreeSpace 4400 system.

4.0 Hardware Installation
4.5 Rack mounting the FreeSpace
4400 system
The FreeSpace 4400 system requires three 1.75" (44 mm) rack
space units with a 16" (406 mm) inside depth (including the rear
supports). When mounting, use four screws with washers to pre
vent marring the front panel. Neoprene rubber washers are a
good choice because they grip the screw head and prevent the
screws from backing out from vibration or during transportation.
Installer’s Note: If the FreeSpace 4400 system is to be
transported while mounted in a rack, be advised that the rear
of the FreeSpace 4400 system must be mechanically supported. Install a shelf under the unit or use brackets in such a
way as to support the rear of the unit. Failure to use proper
mounting hardware may result in damage to the FreeSpace
4400 system during transport.
