1.0 Introduction
1.1The Bose® FreeSpace® E-4 business music system
The Bose FreeSpace E-4 system is an integrated four-channel digital signal processor and 400-watt power amplifier for 70/100V business music applications.
The E-4 system has a total of four source inputs, including two Line In, one Mic/Line and one Mic/Page/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 E-4 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, E-4 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 E-4 system electronics for automated on/off control, source changes, and volume changes according to time of day or day of week
•Opti-Voice® Paging: Provides the appropriate sound level regardless of variations in speech projection
•Source Leveling: Automatically compensates for variations in source input levels
•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
•Contact Closure 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 E-4 system electronics distributes the power based on those needs.
The E-4 also includes an easy-to-replace memory module, which
holds the system configuration settings and design file uploaded by the FreeSpace Installer™ software (see page 7).

2.0 Designing with the E-4 System
2.1 Introduction
This section describes the basic steps for designing an E-4 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 an E-4 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 |

2.2.2Step 2 – Determine Auto Volume requirements
Identify which areas will use Auto Volume. Each Auto Volume zone must use one Auto Volume user interface and one Bose® sensing microphone to control the volume. A 70/100V volume control cannot be used.
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.
The following table provides some guidelines for establishing Auto Volume zones.

|

|
|
|
|
Speaker 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.
When finding mounting locations for the sensing microphones, remember these points:
•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 speaker 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.

Standard and Auto Volume interfaces are available for use with the E-4 hardware. Each offers control over source selection and volume. The Standard interface contains a Mute button, and the Auto Volume interface contains an Auto Volume on/off button. If you have identified an area that uses Auto Volume, you must use an Auto Volume interface to control this zone.
It is also possible to use 70/100V volume controls between the amplifier output and the speaker input. If you plan to use 70/100V controls, 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 a 70/100V 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 speaker requirements
Determine the speaker 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 E-4 output channel.
•Each type of actively equalized speaker requires the dedicated use of one E-4 output channel. If you are designing a system that uses actively equalized speakers, such as the 102®F speaker, Model 32, Model 32SE, or Model 8, you must dedicate one E-4 output channel for each speaker type. If you have a system that uses passive speakers, such as the FreeSpace 3® system, Model 16 or 302™A speaker, you can mix and match them on an E-4 output channel.
Create a speaker map, such as the following, and match the speaker models to areas (Speaker Qty x Tap = Zone Power required):

By combining the maps you can easily combine sources, speaker 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 E-4 system outputs. Area 2 uses one standard volume control requiring one E-4 output channel. Areas 4 and 5 share a common volume control and can be combined on a third E-4 output channel. Since only four outputs are required and the total combined power requirement is less than 400W, only one E-4 unit would be needed for this system.

4.0 Hardware Installation
4.1 Introduction
This section provides instructions for installing the FreeSpace® E-4 system hardware on a tabletop or in a rack.
4.2 Included accessories
The following accessories are shipped with the E-4 unit in the FreeSpace E-4 System Accessory Kit (PC030105).
• 2-terminal input connectors (6) – For wiring sensing microphones
• 3-terminal input connectors (2) – For wiring equipment to the MIC/LINE 3 input
• 4-terminal input connectors (3) – For wiring equipment to the AUX/OUT CONTROL, MIC/ PAGE/LINE 4, and DIRECT IN/CONTROL inputs
•2-terminal output connectors (5) – For wiring speaker cables to the AMP OUT connec-
tions
• Rubber feet (4) – For installing the E-4 unit on a level surface
• Replacement voltage label (2) – Used on OUTPUT VOLTAGE selection switch
• FreeSpace system Installer™ software CD
4.3 Placement guidelines
•Place the E-4 unit where it is protected from heat and allowed adequate ventilation.
•Place the E-4 unit away from direct heat sources, such as heating vents and radiators.
•Make sure that air can circulate freely behind, beside, and above the unit. Allow six inches on all sides.
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 E-4 unit
The E-4 unit is ideal for shelf mounting. The included accessory kit contains four rubber feet for the bottom of the E-4 chassis. The rubber feet will protect the surface on which the E-4 unit is installed and help prevent movement of the E-4 unit. Be sure to follow the “Placement Guidelines” previously described when choosing a location for the E-4 unit.

4.0Hardware Installation
4.5Rack mounting the E-4 unit
Required accessory: FreeSpace® E-4 System Rack Mount Kit (PC029858)
Rack ears |
(8) #8-32 x 1/2 in |
Attaching rack ears to the E-4 chassis
The E-4 unit requires three 1.75" (4.4 cm) rack space units with a 16" (40.6 cm) 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 E-4 unit is to be transported while mounted in a rack, be advised that the rear of the E-4 unit 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 E-4 unit during transport.
