SECTION 7 : JBL DRIVEPACK® TECHNOLOGY Introduction to the JBL DrivePack Integrated Audio System JBL DrivePack equipped loudspeakers are a family of fully integrated audio systems, coupling industryleading loudspeaker technology to a combination of comprehensive digital signal processing and advanced amplifier technology, perfectly matched to the enclosures to deliver superb audio quality and powerful performance.
AC POWER REQUIREMENTS Standard JBL DrivePack systems are equipped with a DP multi-channel Crown Class-I power amplifier and loudspeaker specific DSP electronics and require appropriate AC power. CAUTION: In compliance with safety agency criteria and proper system operation, it is critical that the system installer observe all electrical safety practices at all times and provide proper earth grounding for all AC Power connections.

AC Power Module POWER Indicator: Blue LED – located near power inlet lights when AC power is applied. Amp READY Indicator: Green LED near power inlet, ON during normal operation, long pulse during sleep mode. Sleep Mode: If audio input signals are not detected for 2 hours, the amplifier will go into sleep/standby mode; the amplifier output section is turned off while the supply powering the DP Input Module and DSP logic remains active. This mode reduces current draw and heat loss.
DPIP – Standard Input Module See Figure 1 The standard DPIP input module features analog audio inputs and sophisticated onboard digital signal processing technology. Precision Bandpass limiting, pre-equalization filters and automatic self-test functions ensure optimized performance. JBL engineers have calibrated DSP speaker management and limiter parameters to insure smooth phase response and transfer function curves right out of the box.
DPAN – HiQnet Network Input Module, Analog Audio with Networking See Figure 1a The DPAN input module features analog audio inputs and sophisticated onboard digital signal processing technology. Precision band pass limiting, pre-equalization filters and automatic self-test functions ensure optimized performance. In addition, the DPAN input module adds 100 Mb Ethernet networking functionality and HiQnet compatibility. It enables remote control and monitoring via HiQnet System Architect™ software.

Protective Jackets for Input and AC Power Modules Each VERTEC Series system is supplied with a pair of protective jackets that are designed to fit snugly onto the input and AC power modules of the DP2 or DP1 electronics assembly. These jackets are made of reinforced, weatherized nylon fabric with Velcro attachment strips and drawstrings to secure the opening once installed.
5. Wrap the opposite end of the open jacket around the riser ring as shown in Figure 4. Be certain that the bottom of the protective jacket is tucked-in all the way around the riser ring as shown. Figure 4 6. “Zip” up the Velcro strip and pull the draw cord closed as required as shown in Figure 5.
SECTION 8 : SYSTEM ARCHITECT SOFTWARE The VERTEC DP Series has optional advanced network control capabilities with the DPAN or DPCN input modules. VERTEC DP Series loudspeaker systems so equipped utilize Harman Professional’s HiQnet™ protocol to enable a complete configuration, control, and monitoring solution.
QUICK-START -- CONNECTING PC TO A JBL HiQNet DEVICE FOR THE FIRST TIME: If this your first experience connecting a control computer running System Architect to a HiQnet-compliant JBL product, then this initial test configuration will be useful. It will greatly help to resolve simple networking issues before you connect to multiple devices or connect to a larger network: Step 1) Connect one networked loudspeaker to an unmanaged 100BaseT network switch with a standard CAT5 cable.
Step 4) Now launch System Architect in Windows. Once you see the Venue View of System Architect appear, then proceed as follows. Step 5) Verify that the HiQnet™ network is active by observing the network status icon located at the bottom left of the Venue window. The icon should indicate “Network Active”. If it shows inactive status, double click on the icon and the network will activate. Step 6) Power up the loudspeaker connected to the network.
Step 2) With System Architect running in Windows, power up the remaining loudspeakers connected to the network one or two at a time. System Architect will automatically determine an IP address and a HiQnet Address for each loudspeaker on the network assuming the devices populating the network are new units (DHCP ENABLED). This can require up to 2 minutes in some cases. Once completed an Icon in the venue view will appear representing the JBL Loudspeaker system connected to the network.
VERTEC User’s Guide
GLOSSARY OF TERMS Auto HiQnet Address: When devices boot up, System Architect software, when configured to do so, will automatically negotiate and assign a unique HiQnet™ address to each device. The devices will then keep this address until there is a conflict at start up or the user manually assigns the device a new address.
APPENDIX A: CONFIGURING COBRANET General CobraNet is a licensed technology developed by Peak Audio, Inc. consisting of proprietary communications protocol, firmware and hardware. It allows reliable, deterministic (i.e. real-time) transmission of high quality (i.e. un-compressed) digital audio over standard 100Base-T Fast-Ethernet network. CobraNet will also operate on faster versions of Ethernet (e.g. Giga-bit and 10Giga-bit).
Priority A higher Conductor Priority over-rides a lower priority. If an operating Conductor is removed from the network for any reason (e.g. power turned off ), the remaining devices again arbitrate and select a new Conductor. All CobraNet devices have the capacity to serve as the Conductor. The Conductor periodically broadcasts a well-defined message to all CobraNet™ devices. This allows each CobraNet device to recover the master clock timing information needed for high quality audio delivery.
APPENDIX B: Setting Windows to the Standard Font Size 1. Open the Windows control panel. 2. Double click on the Display panel, the Display Properties panel will open. 3. Next click on the Appearance tab. 4. Go to the ‘Font size’ drop-down menu and select “Normal”. 5. Click on the Apply button, then “OK” to close the Display Properties panel. 6. End.
APPENDIX C: Setting MS Windows Regional and Language Options to U.S. (United States) English 1. Open the Windows control panel. 2. Double-click on Regional and Language Options icon; Regional Options panel will open. 3. Click on the Languages tab. 4. Next, click on the ‘Details’ button.
5. The Text Services and Input Languages panel will open. 6. Go to the Default input language drop-down menu and select English (United States), U.S... Click on the OK button to close the Text Services and Input Languages panel. 7. End.
