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.

4.5 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.

6.3 System setup procedure
The first time you turn on a FreeSpace 4400 system it loads its
factory (default) configuration settings. These settings were
stored in the FreeSpace 4400 when it was manufactured. Once
your PC is fully connected to the FreeSpace 4400 system, you
can use the FreeSpace 4400 Installer™ software to make
changes to the factory configuration settings.
The configuration contains the “start-up” settings for the
FreeSpace 4400 system. Once your work is completed and
flashed to the FreeSpace 4400 hardware, the new settings
become the startup configuration.
1. Select Output Gain for each zone and mute the output. This
prevents any damage to loudspeakers during this proce
dure. This also allows you to work without disturbing any
other people in your work area. See “Output gain” on this
page.
2. Set up the ZONE for each output channel. Choose a
Speaker EQ (default is No EQ) for the speakers you are
using. You can use the Subzones table to document your
subzones. See
3. Set up the Input Gain controls for each source. Choose set-
tings for input type, gain, and source leveling. If the input
type is set for microphone use, you can turn phantom power
(+12V) on or off. See “Input gain” on page 37.
4. Set up the Output Gain controls for each zone. Set the min-
imum/maximum gain (volume) limits and the initial gain level.
See “Output gain” on this page.
5. Select Source Assign for each zone and assign source s for
each. See “Source assign” on page 39.
6. Set up the source EQ for AUX MIC/LINE 3 and
PAGE/MIC/LINE 4 inputs. See “Source EQ” on page 40.
7. Select Page Set Up. See “Page setup” on page 40.
8. Select EQ for each zone. See “Zone EQ” on page 42.
9. Select the Dynamic EQ state for each zone. See “Dynamic
EQ” on page 43.
10. Set up Auto Volume. See “Auto Volume” on page 43.
11. Create a System Schedule. See the “Set Up Schedule
mode” on page 30.
12. Click the flash configurati on button in the upper tool box. You
will be asked to confirm that you want to save the configura
tion to the FreeSpace 4400 hardware. Once you confirm, the

6.0 FreeSpace® 4400 System Setup
Programmer’s Note: If you are using the FreeSpace
4400 system to drive loudspeakers 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 FreeSpace 4400 against loudspeaker transformer saturation when non-Bose loudspeakers are
connected to the FreeSpace 4400 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 FreeSpace 4400 electronics.
If you change the loudspeaker 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 loudspeakers, you could receive an error message notifying you that the
system exceeds the 400 W limitation of the FreeSpace 4400 system. If this problem occurs, delete the subzones from the subzone
list. This will allow you to change the loudspeaker EQ type.
Subzones table – The Subzones table allows you to document
the loudspeakers used in a zone.
A zone is a group of loudspeakers that are driven by the same
amplifier output channel. A subzone is a group of loudspeakers
within a zone that use a common tap or are of a common type.
For example, you may have installed ten Model 16 loudspeakers
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 loudspeakers tapped at 8W and the other with five
tapped at 16W.
To add a subzone
Click the Add button. When the Add Subzone window appears,
enter a name for the new subzone, select the loudspeaker model
installed, enter the quantity, and select a tap setting. The Model
Name list will include only loudspeakers that are compatible with
the Speaker EQ you selected.
Click OK to add the selections to the subzone table.

Input gain setup sequence
1. Set Opti-source® Control 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.
3. 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, incr ease the input gain until the level is gr een.
Likewise, if the level is red, reduce the input gain until the
level is green.
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.
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.

Signal present indicator – The signal present indicator tells you
if a signal is being received by the hardware:
Inactive = No signal
Green = Good signal
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 control is
Off. If you do not see this setting in the control pane, click on
More to display the Opti-source On/Off boxes.

The following chart shows how Opti-source® system 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,
Opti-source leveling will add the necessary gain so that the aver
age output of the Opti-source function is +11 dBV. Sour ces
whose average level is greater than 0 dBV will have gain reduc
tion applied so that they maintain an average of +11 dBV at the
Opti-source leveling output.

6.3.4 Source assign
In the Source Assign control, you can choose which system
sources will be available in each zone. The Source Assign contr ol
panel lists all system sources on the left and zone sources on the
right. Sources are assigned by moving them from the System
Sources list to the ZONE Sources list.
Factory default settings
LINE 1 input source is assigned and routed to all four zones.
Programmer’s Notes:
• Because the FreeSpace 4400 system is a router, at
least one source must always be assigned to a zone.
• If you try to remove all sources from a zone, the last
active source will always remain assigned to the zone.
• This function is disabled for zones in which Auto Volume
is enabled (On). If you turn Auto Volume off and change
source assignments, you will need to recalibrate Auto
Volume.
• Any source assigned to ZONE 4 will also be sent to the
ZONE 4/LINE OUT output.
To assign a source to a zone
1. Select a source in the System Sources list.
When the source appears in the ZONE Sources list, it is
assigned to the current zone. Once a source is assigned to a
zone, that source is no longer available in the System
Sources list and appears grayed out.
To unassign a source
1. Select the source in the ZONE Sources list.
2. Click the left arrow (") button to move the highlighted selec-
tion to the System Sources list.
To route a source to a zone
Double-click on the source in the ZONE Sources list. When the
source is routed, a sounding-loudspeaker icon appears next to
the source.
2. Click the right arrow (!) button to move the highlighted
selection to the ZONE Sources list.

Since the Opti-voice paging system implements predetermined
settings for ducking depth and release time and source EQ, this
is the most efficient setup method. After the Opti-voice paging
system is turned on, the rest of the setup depends on the chosen
detection method.
1. Set Opti-voice control to On in the Page Setup control
panel.
2. Select a detection method. If you select PTT, there is no fur-
ther setup required. If you select Auto, continue.
3. Ask another person to talk into the paging microphone at the
lowest volume that will normally be used.
4. Lower the Page Threshold slider to the level where the page
active light is constantly on.
5. Check your page threshold setting to make sure that no
environmental noise, such as a music sour ce or backgr ound
noise, triggers the page.
If you hear the music source continually ramping up and
down, the environmental noise is triggering a page. If this
occurs, try one of the following:
• Increase the page threshold level.
• Lower the taps on the loudspeakers near the page mic.
• Change the page mic location.

Page setup with Opti-voice® control off
1. Set Opti-voice to Off in the Page Setup control panel. This
enables the Ducking Depth and Release Time controls.
2. Set the Ducking Depth to the amount in dB that the music
will be reduced to once a page is triggered.
3. Set the Release Time to the length of time (secs.) it will take
for the music to return to its original level. The Release Time
can determine the overall quality of a page.
• If you pause frequently while paging or release the pushto-talk (PTT) button during a page, use a long Release
Time.
• If the Release Time is too short, the music will quickly return
and the level will be reduced once the page continues.
Page setup controls
Paging Type – Identifies whether you are using fixed-zone or
multi-zone paging.
• Fixed-zone – Enables paging in all zones that have the PAGE
source assigned to them.
• Multi-zone – Enables paging in all zones that have the PAGE
source assigned to them and allows the user to select each
zone independently using a Page user interface. See
assign” on page 39, “Setting up Multi-zone paging” on
page 41, and “Page user interface operation” on page 51.
Page control – Selects which page keypad is used for paging.
Active only when Paging Type is set to Multi-zone.
Detection type – Determines the page trigger method:
• Auto – Automatically senses input signal level. Requires that
the Page Threshold level be set.
• PTT – Detects contact closure from push-to-talk (PTT) microphones. This disables the Page Threshold slider control.
Opti-voice selection – The Bose® proprietary Opti-voice paging
system provides the appropriate sound level regardless of variations in speech projection. When on, this feature implements predetermined settings for Ducking Depth and Release Time, and
source EQ.
Programmer’s Note: When the Opti-voice paging system is on, the Ducking, Source Leveling, and Input EQ
controls are unavailable. Only when the Opti-voice paging
system is off can these values be changed individually.
Page Threshold slider – The Page Threshold slider setting
determines the signal level required to trigger a page when Auto
Detection is used.
Page Active indicator – The Page Active indicator will be green
when a page is being sent.
Ducking parameters – There are three settings for ducking:
• Depth – Determines how much to reduce the level of program
material when a page starts.
• Release Time – Determines the amount of time to keep program material reduced after a page ends.
• Hold Time – Determines the amount of time that the page
remains active after the page signal has stopped. Page length
and Hold Time determine the point at which the Release Time
starts. See
“Paging operation” on page 42.

When a page signal is triggered, the music signal is ramped
down according to the ducking time. The ducking time is preset
at 20 ms for Auto detection and 0 ms for PTT triggering. The
music level is reduced by the ducking depth which can be
adjusted using the ducking depth control. Ducking depth is
adjustable from 0 to –40 dB. Once a page is completed and the
Hold Time has elapsed, the music volume is ramped up accord
ing to the ducking release time, which is adjustable from 0 to 5
seconds in 0.5-second increments.

6.3.8 Dynamic EQ
The Dynamic EQ control panel pr ovides an on/off control to
enable/disable Dynamic Equalization in the current zone.
Dynamic EQ should only be used in either of th e foll o wing
conditions:
• The system contains extended bass or a FreeSpace® 3 loudspeaker system.
• A user interface is being used to control the volume and no
autotransformers are being used on the loudspeaker line.
When autotransformers are used, the system cannot accu
rately monitor the output level of the system, and as a result,
cannot provide the appropriate response for the current listening level.
Factory default settings
Dynamic EQ is set to Off.
Dynamic EQ compensates for a perceived loss of bass response
at low listening levels. Based on the current output level of the
FreeSpace 4400 system, additional bass and high frequency will
be added.
For Dynamic EQ to operate correctly, make sure the hardware
is connected properly:
• An AVM user interface must be connected to the WALL PLATE
input connector.
• The loudspeaker(s) must be directly wired to the ZONE
OUTPUT connector.

• Make sure that you have selected the correct loudspeaker
model in the ZONE setup pane.
• Make sure that the output gain is set so that the sour ce can be
heard without dropping out.
• Check that sources have been assigned to zones.
Programmer’s Note: If a source is routed to multiple
zones, you need to perform Auto Volume calibration on
that source only once. After calibration, the source is
“locked” (no adjustments to the source will be allowed)
until all zones using that source have been reset.
• Check the EQ pane and make any final adjustments.
• DO NOT USE AUTOTRANSFORMERS: Loudspeakers must
be directly wired to the ZONE OUTPUT connector of the
FreeSpace 4400 hardware. DO NOT use an autotransformer on
the loudspeaker line to adjust the loudspeaker volume. If you
lower the volume using an autotransformer, the FreeSpac e
4400 system will raise the volume. Likewise, if you raise the
volume using an autotransformer, the FreeSpace 4400 system
will lower the volume.

4400 Installer™ software error log
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 ampli
fier will attempt to restart six times, after which it will remain
muted.
Amplifier faults are typically caused by a shorted loudspeaker
line, an overdriven amplifier, or a saturated output transformer.
• To check for a shorted loudspeaker line, remove the loudspeaker 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 FreeSpace 4400
output, change to a different source. If the problem no longer
exists, use the FreeSpace 4400 Installer™ software to reduce

8.3.4 Amplifier alarms
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.
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 approx
imately 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° Fahrenheit
(-18° - 71° Celsius).
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.
Amplifier alarms – using output voltage and
current
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.

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 recor ds you ca n 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.
56 of 66
8.0 FreeSpace® 4400 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 loudspeaker line – Check the loudspeaker line for
shorts.
• System power exceeds 400W – Check that system power
does not exceed 400W.
• Loudspeaker transformer saturation – Check that proper loudspeaker EQ is being used or use a high-pass filter for loudspeaker EQ.
• Line voltage too high (surge) – Check Error Log for a rail voltage that exceeds 150V, in 70V mode, or 190V, in 100V mode.
• 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 FreeSpace 4400 system.
AC Power Fault: Might be an AC line dropout or severe brownout,
or simply AC power turned off without first placing the FreeSpace
4400 in standby mode. You can check that the power has been
removed from the FreeSpace 4400, 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 loudspeaker 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 loudspeakers. When this occurs you should check
the alarm history to determine what other faults occurred at this
time.
High-Frequency Sense Fault: This protection mode is designed
to prevent damage to the amplifier or loudspeakers from exces
sive high-frequency audio or ultrasonic energy. The amplifier is
not capable of sustained operation at full power in the 10kHZ to
20kHz (+) range.
-
Generally, this fault re sults in a one-time 3-second dropout. If,
when the amplifier tries to restart after 3 se conds, th e ex ce ss HF
is still present, the amp (and loudspeaker 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 FreeSpace 4400
system. 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 FreeSpace 4400 system in standby and then press
the STANDBY button again to clear the fault, at which time the
FreeSpace 4400 system will again try to start up.
When this occurs you should check the alarm history section of
the Amplifier Alarm to determine the exact fault type that trig
gered the Retry Fault.
-
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 FreeSpace 4400 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 FreeSpace 4400 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.
