4.2 Ethernet Connection
For all SDEC-3000 installations you will need either a
crossover Ethernet cable or the SDEC will need to be
connected to an Ethernet hub (figure 3). For all SDEC-4000
installations both the SDEC-4000P and SDEC-4000X, as well
as your computer must be connected to an Ethernet hub and
on the same network (figure 4).
NOTE: The below instructions assume you will be using an
Ethernet hub or router. If you are using the SDEC-3000 you
can optionally use a crossover cable and not use a hub.
Figure 5.
Connect the SDEC to an Ethernet router and plug in to AC
(there is no power button). The unit will boot up and acquire a
network address. This can be verified by watching the front
panel display. It will display the boot up message and then
scroll through product ID, Network Address and current time

5.1.2 Distance/Delay settings
5 Software Operation using the
Java Remote
Measure the distance from the center of the listening area (or
the “hot seat”) to each speaker location. The measurement is
accurate to less then one inch.
The SDEC can be controlled and configured from any
computer that has access to the network via Ethernet. All
necessary features can be accessed and all system setup
parameters can be viewed and adjusted using the JAVA
remote but advanced features can only be accessed if using
London Architect to configure the SDEC. You must use
London Architect to access these additional settings. Functions
that cannot be done through the Java Remote include saving
backup copies of the calibrated file to your computer, saving
backup copies to the network device, seeing a graphic
representation of the EQ curve, creating multiple EQ presets
for different modes and recalling different EQ presets.
5.1 Using the JAVA Remote
After connecting the hardware as outlined in Section 4 SDEC
Hardware Connection, open the folder that contains the
Java Remote panel. Once you have opened the folder double
click on the correct file for your hardware you will be prompted
to enter the IP Address that appears on the front of the SDEC
display. Use the file with the same name as your hardware.
The file will end in a .JAR extension. This stands for JaVa
Remote.

6.2.2 Opening from a Network Device
The SDEC allows you to use the unused portion of memory as
a virtual hard drive. This space can be used to store copies of
the design file (as from the factory) or copies of your
customized design for the specific installation you are working
on... To do this select “File” then to “Open from Device
Network” instead of “File” and “Open”
Figure 10.
6.2.5 Design Configuration
Note: Check to make sure that you are using the most current
version of the control file. Please contact JBL Synthesis
Technical Support or your JBL Synthesis Representative for
the most current information.
The design that the hardware has in its memory will be
checked against the design you have in your software. These
must match. If they do not match it will be necessary to have
the design updated. Please call your JBL Synthesis
Representative for instructions. It can be done in the field but
special instructions are needed. The Java remote does not
require and special login.
6.2.3 Firmware Upgrade
If the firmware needs to be updated, check OK to proceed. The
unit may need to be rebooted. The software will check to make
sure the unit has the latest version automatically. You will
receive a message that “No Matched Devices” are found. This
is because the unit is being rebooted during firmware upgrade.
Wait for the unit to reboot and click Online as described
above.

6.3 ONLINE Mode
When in ONLINE mode you are actively controlling the SDEC-3000 or SDEC-4000. The SDEC-4000 can be configured for Full Range
(factory default) or Bi-amp mode. The SDEC-4000 is set to full range to ensure that the bi-amp speakers without built in crossovers will
not be damaged accidentally.
Use the below diagram to help you navigate the system while using the DACS measurement system to calibrate your room.
6.3.1 Speaker Configuration and Instructions
Begin here by selecting the appropriate speaker configuration. If you are using a bi-amp speaker such as in a Synthesis One Array
system, this will also enable the second output from the SDEC-4000
NOTE: You only need to the correct speaker configuration the FIRST TIME you connect to an SDEC. The SDEC will keep the last
setting in non-volatile memory until changed.

6.3.3 Channel Delay (Speaker Distance Offset Correction)
Do not enter the distance measured into the channel distance box. Use the longest measured distance as your 0 reference and
SUBTRACT each speaker distance from this reference. This result is the number you should enter. For example: If the Left is 10 ft from
the primary listening seat and the center is 8 ft, you should enter 0 ft into the left (10 ft – 10 ft = 0ft) and 2 ft (10 ft – 8 ft =2 ft) into the
center.
Measuring and inputting the distance settings for each speaker is a simple process but is does require the installer to follow a simple
procedure. Failure to follow this procedure may result in incorrect settings being input in the EQ.
1. Measure the distance from each speaker to the central, or #1, microphone. This should be the center of the listening area
most likely.
2. Write down the distances for each speaker.
3. Using the longest measured distance subtract this from all the other distances.
4. Enter the result into each speaker distance.
•
Measurements can be in Feet and Inches or Meters
When entering feet and inches use the format of XX’yy” where XX is feet and yy is inches. Use 0” if the distance is 0 different and
0’yy” if the distance is under 1 foot.
•
Note: When measuring and inputting the speaker distances into the SDEC DO NOT input the measured distances.
Type in the correct distance
offset in this box. Enter as feet
and inches or meters and the
correct millisecond delay will
be calculated

6.3.4 Channel Output
Use each output to adjust each channel to give the same output level using an SPL meter.
6.3.5 Level Matching Multiple Surround and Subwoofer Channels
The SDEC-4000 has multiple outputs for Subwoofers and Side Surrounds. These will need to be level matched to each other before
final output levels are set.
1. Using the internal noise test of the SDP test each output individually. It will be necessary to mute the output you are not testing.
Make sure the Trim Link is off (not RED).
2. Once you have set each to the reference level (75dB) enable the Trim Link feature so that the led turns RED.
3. With all the multiple channels un-muted test together and adjust the output to reach the same reference level. You will now have an
output that has all the multiple channels level matched and the overall output set to the reference level.

are two slide switches and a pulse indicating LED. Slide the
ON/OFF switch to the ON position and the output selector to
the LO position. You should now hear pops at one second
intervals from the speaker under test. If a higher level is
required, set the output selector to HI.
8.2.2 Dipole Surrounds
Regardless of model there is one standard for phase
configuration of Dipole surrounds.
8.3.2 Cricket-R
The receiver contains a microphone and phase analysis
circuitry. Positive polarity is indicated by a green LED, negative
by a red LED. Two input connectors and the microphone are
located on the rear panel. There is also a switch marked
"CON" (continuity) and "POL" (polarity). Place this switch in the
"POL" position. On the front panel are two slide switches, a
rotary gain control and the two phase indicating LEDs. Slide
the right side switch to the ON position and place the left side
switch in the MIC position. Now move the receiver’s
microphone toward the speaker being tested. W hen you are
within three to six inches of the speaker you should begin to
see a polarity indication. Adjust the gain control until a
consistent indication of phase is realized.

8.3 Using the Phase Tester
The Galaxy Audio phase tester consists of two battery
operated instruments, Cricket-S is the "sender", and Cricket-R
is the "receiver".
8.3.1 Cricket-S
The sender generates a short duration, positive polarity pulse.
This is applied to the power amplifier input which drives the
loudspeaker being tested. Coincident with the generation of
each pulse, a green LED is illuminated. Three output
connectors are located on the rear panel. Line level male XLR,
line level female ¼" phone jack and a speaker level female ¼"
phone jack. A female XLR to RCA adapter cable is provided in
the kit. Plug this cable into the XLR connector and use it to
connect the sender to each channel for test. On the front panel

3. Slide the WEIGHTING Selector to "C" weighting for
channel balance tests. "A" weighting cuts low frequencies.
This will cause errors when measuring subwoofers.
4. It is recommended that you slide the RESPONSE Selector
to the SLOW position. This slows the meters response to
sudden changes in sound level which can make average
level readings difficult.
9 Setting Output Level
9.1 Setting Levels before Calibrating
Using the internal noise generator of the SDP set all outputs to
achieve 75dB using the “C” weighting and “SLOW” response.
This will maintain the best signal to noise and headroom
possible by optimizing the gain structure of the system.
9.2 Final Level Set after Calibrating
Setting the final output level should be done after all corrective
EQ has been completed. It is very important that this be done
so that all channels have a good balance and are properly
calibrated for the average output in the mid-band frequencies.
Use the internal noise test from the SDP and test one channel
at a time.

Set main and surround channels to 75db.
Set the subwoofer channel to average between 82dB-
85dB.

9.3.2 Digital SLM Instructions
9.2.1 Level Matching Multiple Surround
and Subwoofer Channels
The SDEC-4000 has multiple outputs for Subwoofers and Side
Surrounds. These will need to be level matched to each other
before final output levels are set.
1. Using the internal noise test of the SDP test each output
individually. It will be necessary to mute the output you are
not testing. Make sure the Trim Link is off (not RED).
2. Once you have set each to the reference level of 75dB
enable the Trim Link feature so that the led turns RED.
3. With all the multiple channels un-muted test together and
adjust the output to reach the same reference level. You
will now have an output that has all the multiple channels
level matched and the overall output set to the reference
level. Follow the instructions for level matching the
NOTE: All instruments of this type are most accurate when
operated in the upper end of the selected range. You should
always use the lowest RANGE setting possible. For example, if
you are balancing a system using the Surround Processor's
noise generator (75dB) you would set the RANGE selector to
70dB. In the event you have selected a range that is too low,
an OVER-RANGE condition is indicated by a flashing display.
Select the next higher range.
1. Turn the SLM on by rotating the RANGE Selector
clockwise. Continue to rotate the RANGE Selector to the
desired RANGE.
2. Press the WEIGHTING button to select "C" weighting for
channel balance tests.
3. It is recommended that you slide the RESPONSE
Selector to the SLOW position. This slows the meters
response to sudden changes in sound level which can
make average level readings difficult.
multiple surrounds and subwoofer channels first and then
set the overall output level to the following reference level.
4. Check the display for a low battery indication. If the battery
needs replacing, BATT will appear in the upper left-hand
corner of the LCD display. Replace the battery if
necessary.
9.3 Using the SPL Meter
9.3.1 Analog SLM Instructions
NOTE: All instruments of this type are most accurate when
operated in the upper end of the selected range. You should
always use the lowest RANGE setting possible. For example, if
you are balancing a system using the Surround Processor's
noise generator (75dB) you would set the RANGE selector to
70dB.
1. Rotate the RANGE Selector clockwise one click to the
BATTERY TEST position. Observe the meter indication. A
reading anywhere within the red BATT TEST range
indicates adequate battery power. If the indication is below
this range, replace the battery before using the instrument.
2. Now rotate the RANGE Selector clockwise to the desired
range. The meter has a display range from -10dB to +6dB.
The 0dB point corresponds to the RANGE selected.
Therefore, if the 80dB RANGE is selected, a 0dB reading
will equal 80dB.

Test each channel using the DACS calibration kit and copy EQ
filter suggestions from DACS to London Architect. It will be
necessary to test each channel using the DACS. If you use F4
the DACS will test and suggest filters to use. Copy these filters
for each channel.
10 DACS Measurement System
10.1DACS Hardware Setup
Unpack the DACS Kit and setup the microphone array. Make
all standard connections except for connecting to the SDEC.
Use the below diagram as a guide.
Note: The DACS may suggest more filters than you have
available. In this case you will need to decide what filters
are necessary and audible. In general the filters than
suggest under 1db of change can be ignored.
Note: Please refer to the DACS manual that comes
with the DACS Kit for detailed instructions.
Click on the
box and type
in the value
Figure 18.
10.2Channel Test and System
Calibration
Use the DACS to test the channels one at a time, to make
suggestions for filter settings. When using the DACS computer
the basic workflow is as follows:
Figure 19.
As you copy the filter EQ setting from the DACS to the London
Architect you will see the resulting EQ curve. If you are using
the web interface (Java Remote) you will not see the EQ curve
display. This is normal.
Make sure you have set the processor to Dolby Pro Logic
and the volume is at 0dB.

•
In the DACS computer you will press F2 (TEST) to test
and check level
Press F4 (AUTO EQ) to test and allow the DACS to
suggest EQ settings
When each channel is done you can press F5 (NEXT) to
go to the next channel to test
Use the London Architect software to mute the channels
you are not working on and to input EQ filter settings.
When testing the rear channels you will use the “Ambient
L or Ambient R” channels in the DACS. These channels
will be used for both the SIDES and REARS. Simply mute
the unused channel from within the London Architect
Software. It is best to test the Left Side and then the Right
Side before testing the Left Rear and Right Rear channels.
Use the System Control to select channels and use the matrix
to mute the channel “on” and “off”, don't forget to “un-mute” all
at the end.
•
You will start by MUTING all channels except the Sub-
Woofer.
•
Once you have tested and calibrated the Subwoofer you
will un-mute only the channel you are working PLUS the
subwoofer.
•
Test the Side and Rear speakers with the Subwoofer
Muted.

Recalling your settings assumes that you are using London
Architect to open and control the SDEC. If you are using the
web interface (version 1.01 of the design file or higher) you will
not need to recall settings as the settings will automatically be
recalled. Settings can be retrieved from a number of different
ways. Please read below for the different options. The London
Architect software will automatically check to match the
settings in your software against the hardware and give you
options when opening the file and going online.

12.2Recalling without a Saved File
You must have a copy of the same design file that you
originally used to do the calibration, even if you have not a
saved copy. This is the same file that is saved in the SDEC but
all the settings are flat with no EQ or calibration settings saved.
This is the file you would have received from JBL Synthesis or
opened from the device network originally. Using this “blank”
file to connect to the SDEC. When you first go online you will
be prompted to select from synchronizing the settings from
your computer software or synchronizing from the hardware
device. Choosing hardware device will recall all the settings
from the hardware and show them in the software on your
computer.
11 Saving Your Work
The SDEC-3000 and SDEC-4000 DO NOT REQUIRE that you
save at any time. When you are online and operating the unit
your settings are being stored in protected memory at all times
and no save process is required or possible. Saving your work
is completely a safety copy in case anything happens to either
the SDEC or your computer.
Once you have completed the calibration and the final
subjective listening tests you can save your work. Two copies
should be saved. The first is a copy on your computer that you
can distribute to other installers or keep as a backup on your
own computer incase anything happens to the SDEC. The
second is a copy that will be kept on the SDEC itself that can
be retrieved in case your copy becomes corrupted or lost.
12.3Recalling from Network Device
If a copy of the file has been saved to the SDEC itself it can be
recalled from the device. After opening the London Architect
software go to Fileꢂ Open from Network Device. You will be
prompted for a password and user login if necessary and
shown a list of available files to open.
11.1Save a copy using SAVE AS
Once finished but still connected to the Ethernet Network go
OFFLINE by clicking on the green check box labeled ONLINE.
This will disconnect your software from actively controlling the
unit. It is now possible to use Save As from the File menu and
save a copy as any other Windows file can be saved.
11.2Save to Network Device
Once finished but still connected to the Ethernet Network go
OFFLINE by clicking on the green check box labeled ONLINE.
This will disconnect your software from actively controlling the
unit. You must first save the file to your computer using
SAVE AS and name it a unique name for this install. It is
now possible to use Save To Device Network from the File
menu and save a copy to the SDEC itself. This can be
retrieved by using the Open from Device Network menu

13 Advanced Features
13.2Multiple EQ Presets
13.1Cinema/Music Subwoofer Output
Up to two EQ presets can be stored and recalled. All channels
can be changed and are saved and recalled together. Due to
the advanced nature of this process it should only be done
under the supervision of JBL Synthesis factory personnel.
The SDEC has the ability to change the subwoofer output gain
to accommodate both the standard cinema curve and a more
linear music output level. This feature has been built into the
SDEC as a simple alternative to the multiple EQ presets that
would otherwise be necessary as described in Section 13.2
13.2.1
Saving Presets
Multiple EQ Presets. Changing the output level of the
subwoofer using this preset will not have an effect on your
standard calibration. The default setting is Cinema with no
change to the output level. The preset can be triggered in three
ways: (1) via RS232; (2) via Ethernet; (3) via the contact
closure trigger on the rear panel.
Please contact JBL Synthesis Technical support for this
feature. It requires advanced training and the use of London
Architect. It cannot be used with the Java Remote. As this
feature is considered an advanced feature there is the
possibility of loosing your work if you do not have the proper
training. Due to this possibility JBL Synthesis is not releasing
the information except to qualified personnel who have
undergone advanced training with JBL Synthesis personnel.
Note: You must have SDEC3000/SDEC4000 version 1.10 or
higher for this feature.

If both the hardware and the software have the same version
of the control and design configuration then the software will
check to see of the settings and parameters match. If they do
not match you will be given the option to synchronize the
settings. You will be prompted to tell the software whether you
want to use the settings from your computer, or load the
settings from the hardware. If you are starting a new calibration
or want to replace what is set in the EQ with your settings from
the computer, select update from software. If you have already
begun the process and want to continue your work, or use the
settings in the EQ as a starting point, then select update from
hardware. Select the green arrow to send your values from
your saved file or select the red arrow to receive the values
from the hardware. The unit name will highlight in green when
done. Click OK to continue.
