1.0 E4 Introduction
1.1 The Bose® FreeSpace® E4 Series II
business music system
• 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 E4 system
electronics distributes the power based on those needs.
The E4 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 14).
1.2 E4 system accessories
The Bose FreeSpace E4 Series II system is an integrated fourchannel digital signal processor and 400-watt power amplifier for
70/100V business music applications.
The E4 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 E4 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, E4 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 E4 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 E4 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.
Optional Bose accessories for the E4 system are available.

This section describes the basic steps for designing an E4 system and includes an example. It is assumed that a complete
loudspeaker design and layout has already been created.

There are five basic steps in designing an E4 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.

<12 ft (3.7 m)
One Auto Volume
zone for every
1800 ft2 (162 m2)
One Auto Volume
zone for every
900 ft2 (81 m2)
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.
●
●
12-25 ft
(3.7-7.6 m)
●
●
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 speaker height.
●
2.2.2 Step 2 – Determine Auto Volume
requirements
• 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.
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.
• There must be 35 ft (10.7 m), minimum, between the sensing
microphones of two adjacent Auto Volume zones.
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
• 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

2.2.3 Step 3 – Determine volume
control requirements
2.2.4 Step 4 – Determine the speaker
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.
Determine the speaker coverage required for the design. Consider the following points as you do this:

• Each type of actively equalized speaker requires the dedicated
use of one E4 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 E4 output channel for each speaker type.
●
●
Area 2
Area 3
• Each Auto Volume function requires a separate zone. Each
Auto Volume zone requires the dedicated use of one E4 output
channel.
Create a speaker map, such as the following, and match the
speaker models to areas (Speaker Qty x Tap = Zone Power
required):
●
●
Model
32SE
●
Standard and Auto Volume interfaces are available for use with
the E4 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. 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.

2.0 Designing with the E4 System
2.2.5 Step 5 – Determine the E4
requirements
Now we can take a look at how the maps we created can help us
determine the quantity of E4s we will need.
Once you have identified the areas that use Auto Volume and
unique loudspeakers, you can combine different areas based on
the types of sources and controls they are using.

Total System Power = 250W
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 E4 system outputs. Area 2 uses one standard volume control requiring one E4 output channel.
Areas 4 and 5 share a common volume control and can be combined on a third E4 output channel. Since only four
outputs are required and the total combined power requirement is less than 400W, only one E4 unit would be
needed for this system.

The E4 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 E4 unit is to be transported while
mounted in a rack, be advised that the rear of the E4 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

5.5.1 Setting the clock
The date and time of the hardware clock is initially set in Eastern
Standard Time. After your PC is connected to the hardware,
check the clock and set it as necessary for the time zone and
region of your installation.
Adds a system Auto On/Off event
This event applies only to the whole system. You can select individual on or off times for the day(s) you choose. Or, you can
select on and off times in a single statement.
Programmer’s Note: One Auto On/Off event specifies
both an “On” time and an “Off” time and is counted as two
events.
To adjust the clock settings manually, click the Set Clock button
in the clock panel. The Clock Settings window opens, allowing
you to make adjustments to the date and time. Click Apply or OK
to set the clock in the hardware, or click Cancel to close the window and leave the clock settings unchanged.
Adds a zone Mute event
This event allows you to mute/unmute the zone output at a
specified time on selected days of the week.
5.5.2 Adding events
When you click the On/Off, Volume, Source, or Auto Volume
event button, an event of that type is added to the event list. At
this point you can change the event settings. When the event list
exceeds the length of the pane, the software will add a scroll bar
on the right side.
A maximum of 64 events may be added to a system. This means
that the total number of events from all event lists must not
exceed 64. An On-Off event consumes two events, while source
change, volume change, and Auto Volume events consume one
apiece. A counter is provided in the Schedule mode window to
keep track of the number of remaining events.
Adds a zone Volume Change event
This event allows you to change the volume level at a specified
time on selected days of the week.
Remaining events
counter
Programmer’s Note: The maximum/minimum volume
stops cannot be adjusted in this pane. To adjust these limit
stops, select the Output Gain function in the Set Up Hardware mode.
Zone events programmed to occur at the same time as a “System ON” event will not occur. To ensure that zone events will happen, they must be programmed to occur 15 minutes after the
“System ON” event. For example, if a “System ON” event is programmed to occur at 8:00 AM, the first zone event should be programmed to occur at 8:15 AM.
Installer’s Note: Flashing the Installer software configuration file to the E4 unit sets the default state of the system
when it is turned on. Whenever possible the default state of
the system should be set to meet the requirements most likely
to occur after a scheduled “System ON” event.

5.5.3 Viewing and changing event
settings
Adds a zone Source Change event
This event allows you to change the source at a specified time on
selected days of the week.
To view any event and change the settings, first click the system
or one of the zone tabs. Then select an event in the list to display
the event settings in the control pane. Now, you can edit the settings just as when an event is added.
5.5.4 Removing events from the list
To remove an event from the list, select the event by clicking on it
and then click the
(Remove Event) button.
Programmer’s Note: After changing any event settings
or removing an event from the list, you must flash the
hardware in order for the change to take effect.
Adds a zone Auto Volume event
This event allows you to turn Auto Volume on or off at a specified
time on selected days of the week.
Programmer’s Note: Do not schedule an Auto Volume
event on a zone that is not set up for Auto Volume.

6.0 E4 System Setup
Programmer’s Note: If you are using the E4 system to
drive speakers that are not Bose® products, choose the
No EQ setting or one of the four high-pass filter settings
at the end of the list.
The No EQ setting helps protect the E4 against loudspeaker transformer saturation when non-Bose loudspeakers are connected to
the E4 hardware. This setting acts as a band pass filter and allows
energy between 80 Hz and 16 kHz to be sent to the amplifier section of the E4 electronics.

If you change the speaker EQ type, any subzones will be automatically changed to the new Speaker EQ setting, and be given the
default loudspeaker tap. Depending on the quantity and tap of
speakers, you could receive an error message notifying you that the
system exceeds the 400 W limitation of the E4 system. If this problem occurs, delete the subzones from the subzone list. This will
allow you to change the speaker EQ type.
Subzones table – The Subzones table allows you to document
the speakers used in a zone.
A zone is a group of speakers that are driven by the same amplifier output channel. A subzone is a group of speakers within a
zone that use a common tap or are of a common type.
For example, you may have installed ten Model 16 speakers in a
dining room and set it up as a zone to be driven by channel 1. In
this zone you may have established two subzones, one with five
Model 16 speakers tapped at 8W and the other with five tapped
at 16W.

Input gain setup sequence
Input gain meter – The input gain meter indicates the average
input signal level of the hardware. The meter is divided into three
color segments:
1.
Set Opti-source® to Off. This allows you make the initial
gain setting.
2.
Select the source Type and determine if Mic Power +12V is
needed. Set Mic Power to On if required. Leave it in the Off
setting if you are using line inputs.
Amber = Low signal level
Start your input source and monitor its signal on the gain
signal level meter. If the level is green, go to step 4. If the
level is yellow, increase the input gain until the level is green.
Likewise, if the level is red, reduce the input gain until the
level is green.
Red = High signal level
3.
Green = Good signal level
Signal present indicator – The signal present indicator tells you
if a signal is being received by the hardware:
Inactive = No signal
Green = Good signal
Programmer’s Note: You may have to repeat step 3 a
few times if the input source is a CD player. The output
level of a CD player varies based on the program material.
4.
Set Opti-source to On. If you are using a source that
produces a varying output level due to program material,
such as a CD player, Opti-source leveling will compensate
for these variances. If your system will be switching among
multiple sources, Opti-source leveling will compensate for
variances among the different sources.
5.
Repeat steps 1 to 4 for the remaining system inputs.
Red = Signal clipping
Opti-source – This is the on/off control for this function. When
on, Opti-source leveling automatically manages the input gain
level so that the full output of the amplifier can be achieved. It
does this by adjusting the input signal level to obtain the desired
amplifier input signal level (+11 dBV). When setting the initial
input gain level, check to make sure that Opti-source is Off. If you
do not see this setting in the control pane, click on More to display the Opti-source On/Off boxes.
Programmer’s Note: The Opti-source state cannot be
changed when the Opti-voice® paging system is on.
When you turn Opti-source on, you should only hear a small
change in volume. If you hear a large increase, raise the input
gain. Likewise, if you hear a large decrease, lower the input gain.

The following chart shows how Opti-source leveling operates.
For sources whose average input signal level is less than –20
dBV, Opti-source leveling will add 20 dB of gain. For sources
whose average signal level is between –20 and 0 dBV, Optisource leveling will add the necessary gain so that the average
output of the Opti-source function is +11 dBV. Sources whose
average level is greater than 0 dBV will have gain reduction
applied so that they maintain an average of +11 dBV at the Optisource leveling output.

input gain. Changes in the slider's position are continuously sent
to the E4 hardware so you will hear the change in gain as it is
applied and see the change in the signal level on the meter. The
gain range is dependent on the Type setting: 80 dB for Mic; 70 dB

8.0 E4 System Troubleshooting
8.1 Introduction
This section provides troubleshooting guidelines to use for solving any problems you may encounter while installing and servicing E4 systems.
8.2 E4 hardware indicators
To determine the severity of the error, cycle the E4 unit power off
and back on again. If the SYSTEM STATUS indicator is now off,
the E4 system has logged an error, but is still operational.
When you check the error log using the FreeSpace® Installer™
software you can identify the cause of the error, and determine an
appropriate solution.

When an amplifier fault occurs, the amplifier mutes its outputs
and indicates an error. After a short period of time the amplifier
will try to operate again. If the fault condition persists, the amplifier will attempt to restart six times, after which it will remain
muted.
Amplifier faults are typically caused by a shorted speaker line, an
overdriven amplifier, or a saturated output transformer.
• To check for a shorted speaker line, remove the speaker connection from the amplifier channel. If this resolves the problem,
locate and correct the shorted loudspeaker line.
• To make sure that you are not overdriving the E4 output,
change to a different source. If the problem no longer exists,
use the Installer™ software to reduce the input level of the original source that was overdriving the output.
• To make sure an output transformer is not being saturated,
check to see if the correct speaker EQ setting is selected.

appear in the host controller flash test section. If this occurs,
contact Bose Customer Service. See “Customer support” on
page 70.
• Peripheral controller – The peripheral controller monitors contact closures, front panel connections and user interface connections for incoming event messages. Any failures in these
areas will cause the message, “Power-on self-test incomplete”
to appear in the peripheral controller flash test section. If a 12C,
or code failure occurs, contact Bose Customer Service. See
“Customer support” on page 70. If a user interface failure
occurs, check the user interface wiring for shorts.
• DSP test – The DSP performs all signal processing and routing
functions. If a DSP error occurs, contact Bose Customer Service. See “Customer support” on page 70.
8.3.2 Hardware configuration
The E4 system hardware version numbers appear at the top of
the Error Log listing. These are the version numbers of the software installed in the E4 hardware at the time of manufacture.
These version numbers do not pertain to the FreeSpace
Installer™ software installed on your PC.
8.3.3 Power-on self-test results
The power-on-self test (POST) results are only displayed when an
error has occurred. The POST test checks the basic operation of
the E4 hardware to determine if it is capable of properly performing audio processing and amplification. During the POST test, six
major components of the hardware are tested.
• Upper and lower amplifier test – The upper and lower amplifier test determines if the amplifiers are operating properly. An
amplifier failure will cause the message, “Power-on self-test
incomplete” to appear in the upper or lower amplifier section of
the POST test results. If a 12C, or code failure occurs, contact
Bose Customer Service. See “Customer support” on page 70.
Additional details on the exact cause of an amplifier failure can
be found in the amplifier section of the Error Log.
• Front panel board test – The front panel board test determines if the USB port is working properly. A USB failure will
cause the message, “Power-on self-test incomplete” to appear
in this section of the POST results. If a USB failure occurs, contact Bose Customer Service. See “Customer support” on
page 70.
65 of 80
Programmer’s Note: The USB port is not currently
used for communication with the E4. If a USB failure
occurs, the E4 will still function normally for audio processing and amplification.
8.0 E4 System Troubleshooting
8.3.4 Amplifier alarms
Amplifier alarms – using output voltage and
current
Each amplifier section monitors its own operation and performance. If a fault condition occurs, it is reported in the Amplifier
Alarm section of the Error Log. Upper amplifier alarms affect
channels 1 and 2, and Lower amplifier alarms affect channels 3
and 4.
Reviewing the output voltage and current can help to diagnose a
problem. Compare the output voltage and current for each of the
two amplifier outputs to determine the nature of the problem.
High Voltage
(>20V)
The amplifier section of the alarm log indicates the following:
• Alarm type – The generated alarm type is the first item.
• Amplifier status – When an alarm is generated, the amplifier
reports its current operating status for diagnostic purposes.
The following items are reported in the status:
Date & Time: Date and time when alarm condition occurred.
Rail Voltage: The amplifier positive and negative rail voltages.
Normally, the amplifier rail voltage should be between 100V
and 190V. Voltages outside this range will cause the amplifier
to shut down. In the 70V mode, a normal rail voltage is approximately 125V. In the 100V mode, a normal rail voltage is
approximately 165V.
Temperature: The internal operating temperature of the amplifier.
Normally, this will be between 0 and 160 degrees Fahrenheit.
Output Voltage: The actual output voltage of the amplifier at
the time of the alarm.
Output Current: The actual output current of the amplifier at the
time of the alarm.
Input Status: The status of the input signal to the amplifier.
Possible status messages are DC sense fault, amplifier module
fault, AC power fault, sleep mode, high-frequency sense fault,
and retry fault.
Output Status: The status of the amplifier output at the time of
the alarm. Possible status messages are “amplifier module
muted,” and “speaker relay off.”
Fan Speed: The fan speed at the time of the alarm.
Operating Mode: The current setting of the output voltage
select switch, 70V or 100V.
Low Voltage

Short on speaker line
Amplifier alarms – using rail voltage
Normally, the amplifier rail voltage should be between 100V and
190V. In the 70V mode a normal rail voltage is approximately
125V. In the 100V mode a normal rail voltage is approximately
165V.
By comparing the + and – rail voltages, you can determine if you
are driving an impedance which is too low (<12Ω). In this case the
difference between the two rails will probably be greater than
20%.
If one of the rails shows a voltage, and the other does not, the
amplifier should be replaced.
As you review all alarm records you can compare the plus rail
voltage in each of the status sections. For example, a drop of
50% in one status could indicate a brownout condition occurred.
Amplifier alarms – input and output status
The Input and Output Status sections display the fault condition
which caused the alarm and the current status of the amplifier
output.
66 of 80
8.0 E4 System Troubleshooting
A number of fault conditions can be displayed in the Input Status
section:
DC Sense Fault: A power supply fuse, output FET, amplifier module, or some combination of the above has blown. The unit
should be replaced.
Amplifier Module Fault: When the Amplifier Module fault occurs
by itself it can be caused by any of the following:
• Shorted speaker line – Check the loudspeaker line for shorts.
• System power exceeds 400W – Check that system power
does not exceed 400W.
Generally, this fault results in a one-time 3-second dropout. If,
when the amplifier tries to restart after 3 seconds, the excess HF
is still present, the amp (and speaker relay) will remain off for
another 3 seconds and the loop repeats. Six of these in a row will
cause the amp to shut down, and will trigger a Retry Fault.
When this fault occurs you can check your program material for
excessive high-frequency content, or for a potential ground loop
which has created an oscillation internal to the E4 unit. You can
also reduce the output gain for this amplifier zone in an attempt
to reduce the high-frequency energy going to the amplifier.
Retry Fault: The amplifier has tried to start up or recover from a
fault condition at least six times. When this occurs, you will need
to place the E4 unit in standby and then press the STANDBY button again to clear the fault, at which time the E4 unit will again try
to start up.
• Speaker transformer saturation – Check that proper speaker
EQ is being used or use a high-pass filter for speaker EQ.
• Line voltage too high (surge) – Check Error Log for a rail voltage that exceeds 150V, in 70V mode, or 190V, in 100V mode.
When this occurs you should check the alarm history section of
the Amplifier Alarm to determine the exact fault type that triggered the Retry Fault.
• Line voltage too low (brownout) – Check Error Log for a rail
voltage which is lower than normal by at least 20%.
• 70/100V mode switched with unit operating – Check that output voltage and AC input voltage selector are correct.
• Blown power supply fuse (as opposed to AC line fuse) –
Replace the E4 unit.
AC Power Fault: Might be an AC line dropout or severe brownout,
or simply AC power turned off without first placing the E4 in
standby mode. You can check that the power has been removed
from the E4, or that you experienced a power dropout.
Sleep Mode: The host microcontroller has told the amplifier and
power supply to turn off. This only occurs in conjunction with
another alarm (usually AC power fault), because it in itself is not
an alarm condition. When an AC power dropout occurs, the
amplifier immediately shuts the amplifier and speaker relay off,
then the other processing is shut down. This all happens fast
enough to prevent data loss or corruption, and to prevent loud
pops in the speakers. When this occurs you should check the
alarm history to determine what other faults occurred at this time.
Input and output alarm history
This part of the Error Log displays the sequence of fault conditions where “0” is the initial fault reported followed by “1-6”.
These occur over a very short period of time.
8.3.5 Solving faults reported in the
Error Log
When errors are reported in the Error Log, you can try to solve the
problem by performing one of the following actions:
• On the E4 rear panel, turn the POWER switch to OFF. Wait a
few seconds and turn the POWER switch to ON. Then press
STANDBY on the front panel.
• On the E4 rear panel, turn the POWER switch to OFF. Disconnect all input/output signal cables. Wait a few seconds and
turn the POWER switch to ON. Then press STANDBY on the
front panel. Reconnect one cable at a time and check the Error
Log.
High-Frequency Sense Fault: This protection mode is designed
to prevent damage to the amplifier or speakers from excessive
high-frequency audio or ultrasonic energy. The amplifier is not
capable of sustained operation at full power in the 10kHZ to
20kHz (+) range.

• Maximum output gain is less than -20 dB
• E4 Error Log file
• Source is not operating
• Computer make, model, and configuration (hard drive storage
capacity, processor speed, and amount of installed RAM)
• Source level is too low
Calibration could also fail if the calculated loop gain is not within
required limits. This may be due to:
• Broken microphone cable
• Speakers are not connected
• Sensing microphone is not connected, or is connected to the
wrong zone
8.5 Customer support
• Description of the problem – Can it be reproduced? If so, what
steps can be taken within the application to make the problem
manifest itself?
If possible, attach the Installer™ software diagnostic files. The
Installer software creates three important diagnostic files (output,
error, and log) each time the software runs. These files are distinct
from the E4 Error Log file which refers to the hardware errors and
can be accessed using the Service tab within the Installer™ software.
The name of each Installer diagnostic file includes the date and
time that Installer software was run. For example:
