1 Introduction
Welcome to the JBL Synthesis and DACS user guide. The below information is designed to help an installer use the SDEC and DACS
kit to properly test and calibrate a room. This guide is designed to help guide you through the calibration process when using the
original DACS Digital Acoustic Calibration System with the newly introduced SDEC-3000 and SDEC-4000 digital EQ systems.

SHIPPING THE DACS KIT TO THE NEXT DEALER
By the time you have completed your Client's installation, you should have received a FAX or email giving detailed shipping
instructions. If you have not received this information, please call immediately and request shipping information.
Unless otherwise instructed, always ship via UPS Blue.
When shipping, always insure kit for $15,000.00
2 Equipment Required:
• PC with windows XP (Windows 2000 supported, for use with Windows 2000 the MDAC database components will need to be
downloaded from www.microsoft.com) and one Ethernet Network port. Windows Vista has not been tested as of the writing of this
manual.
PC must have BSS Audio London Architect installed to access advanced features. Please contact JBL Synthesis
Technical Support for download instructions
PC should be set to DHCP (default)
PC may need to have Windows® firewall turned off
• 3 Standard Ethernet Network cables (for SDEC-4000). 2 Ethernet cables are needed for SDEC-3000.
• 4 port (or higher) Ethernet hub or router. JBL Synthesis has used the Linksys® brand of compact Wireless-G broadband Router
with good results. Four ports are required for use with the Harman Audio Test System (HATS™) system to be released in the
summer of 2008.
• DACS calibration kit. These are available from JBL Synthesis on a loaner basis. The kits are not for sale and are used by all our
dealers. Please contact Luisa Welsh at (818) 830-8757 to reserve your kit. The kit includes all additional tools you will need.

3 Calibration Checklist
The calibration process is more than just measuring and applying EQ to achieve a preset target. It includes examining the entire signal
chain and confirming that all parts of the system are accurately connected. Use the below checklist to make sure you have completed
all the steps to ensure that your system meets the standards for the best audio system possible.
Follow this list in the order below and you will be guaranteed a great
sounding and properly calibrated JBL Synthesis installation.
Speaker placement and installation is correct (page 16 - Speaker Sound Check)
Correct connection from Preamp to EQ to Amplifier to Speakers (page 6 -
Audio Connections)
Connection of SDEC to Ethernet Network (page 8 - Ethernet Connection)
Phase test of each speaker (page 16 - Speaker Phase Test)
Set all preamp bass, treble, and speaker distances to flat or 0
All bass management crossover points should be set to 80Hz. Do not use
80Hz THX
®
(See the SDP processor installation manual)
Measure and input speaker offset correction (page 9 for Java Remote -
Distance/Delay settings or page 14 for London Architect - Channel Delay (Speaker Distance Offset
Correction)
Use internal noise test and adjust SDP output levels to set nominal
reference level of 75dB using SPL meter before beginning room
correction EQ (page 18 - Setting Levels before Calibrating)
Set Processor to Dolby ProLogic and set volume to 0dB
Run room measurement using the DACS system and enter corrective EQ
settings (page 19 - DACS Measurement System)
Set final levels for system using SPL meter to balance overall output for
each speaker using gain adjustment in SDEC (page 15 - Level Matching Multiple
Surround and Subwoofer Channels)
Use test DVD to confirm results using the subjective listening tests
Save the SDEC settings file for backup to both your computer and the
network device (SDEC) for future recall (page 20 - Saving Your Work London
Architect software only)

4 SDEC Hardware Connection
Please refer to the SDEC Installers Manual for detailed hardware connection instructions and diagrams. Check the SDEC for correct
connection using the below chart for SDEC-3000 and the next page for SDEC-4000 installations:
• Make sure you have access to the SDEC-3000 or SDEC-4000P and SDEC-4000X Ethernet port(s).
• Make sure you are using the correct interconnect kit, S3000IC or S4000IC.
• The system should pass audio and all channels should operate before beginning the calibration.
• The SDEC-4000P and SDEC-4000X need to be connected to each other via the Cobranet® connection using a CAT5e crossover
network cable and must be a minimum of two feet (0.7 meter) long.

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 3. SDEC-3000
Figure 4. SDEC-4000
4.2.1 Initial Network Connection
Plug router in to AC and make sure it is powered ON
Begin with PC OFF, SDEC UNPLUGGED (no power). Connect
PC to Ethernet router and boot PC. It should acquire a network
address. This can be verified in Start Menu Control Panel
Network Connections Local Area Network Support
Tab. Prior to getting the SDEC-3000 or 4000 On-line and
working turn it may be necessary to turn off your Windows
internet firewall on your computer so that you can talk to the
EQ (you do this from the “Control Panel”).
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
