1.0 FreeSpace® 4400 Introduction
1.1The 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 business 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 output 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 FreeSpace system Auto Volume Sense Mic, FreeSpace 4400 system electronics dynamically control the program level in each zone so your customers can always hear it, regardless of the background noise.
•Scheduling: Allows you to program the FreeSpace 4400 system 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 balance in each zone.
•Signal Routing: Meets the demands of most four-zone systems, 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).
1.2 FreeSpace 4400 system accessories

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 created.
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 2 |

2.2.2Step 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 Bose® sensing microphone to control the volume.
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 dining area. Likewise, if you place the sensing microphone above the dining area, the music may never be heard in the bar.

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.
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 Volume, it is possible to create a situation in the dining area where the music is too loud simply because the microphone is too close to the bar.

AVM (Auto Volume/Mute) user interfaces are available for use with the FreeSpace® 4400 system. They offers control over 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 configure 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 control 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 rarely used or it requires a secure location, it should be placed with the equipment. If the control is for an area that requires frequent adjustments, then it is best to place the control in the area being controlled.
2.2.4Step 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 following, and match the loudspeaker models to areas (Loudspeaker Qty x Tap = Zone Power required):

2.2.5Step 5 – Determine the
FreeSpace® 4400 requirements
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.

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 Area 3 need to be grouped separately because they are Auto Volume 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.

The following accessories are shipped with the FreeSpace 4400 system.
• 2-terminal input connectors (7) – For wiring Auto Volume mics to the
SENSE MICROPHONES jacks
• 3-terminal input connectors (2) – For wiring equipment to the AUX MIC/LINE 3 jacks
• 4-terminal input connectors (4) – For wiring equipment to the ZONE 4 LINE OUT,
PAGE/MIC/LINE 4, and DIRECT IN/CONTROL jacks
• 2-terminal output connectors (5) – For wiring loudspeaker cables to the ZONE OUTPUT jacks
• Rubber feet (4) – For installing the FreeSpace 4400 system on a level surface
• Rack ears (2) ) – for rack mounting the the unit. Includes (8) M4 x 12mm screws.
• Replacement voltage label (2) – Used on the OUTPUT VOLTAGE selection switch
• FreeSpace 4400 Installer™ software CD – Contains application software for programming the FreeSpace 4400 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 surface 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 prevent 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.
