INTRODUCTION TO THE JBL DRIVEPACK
®
DPC-2 INTEGRATED AUDIO SYSTEM
JBL DrivePack equipped loudspeakers are a family of fully integrated audio systems, coupling industry-leading
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.
Designed in cooperation with Crown International, the DCP-2 features Dual Bridged Technology™. Each
discrete amplifier channel is linked to one voice coil of the Differential Drive loudspeaker. Electrical power
transfer to the transducer is optimized for maximum system performance. The DrivePack includes onboard
DSP functionality and displays lighted system status indicators during operation.
DRIVEPACK SIGNAL-PROCESSING & AMPLIFICATION UNIT
The DrivePack electronics unit is intended to be used when mounted to a speaker enclosure of
5/8" minimum thickness of wood or composite material and with load impedances of 2 to 4 Ohms
for low and mid frequency channels, and 4 to 16 Ohms for the high frequency channel.
OPERATING INSTRUCTIONS
All that is required to get your DP compatible loudspeaker system up and running is to verify that the main panel
voltage select switch setting is appropriate for the power in your area, connect an AC power source to the AC
Power panel via the Neutrik twist-lock PowerCon
®
inlet connector, and connect a full range line level audio signal
to the Input panel via the AUDIO IN XLR connector.
The JBL DPC-2 is equipped with a manual select 115V/230V Power Supply and can operate anywhere in the
world that has an available 100-120VAC or 200-240VAC power source. Upon initial power-up of the DrivePack,
the AC soft-start process will begin and the Blue Power LED illuminates when boot-up is completed.
AMPLIFIER PROTECTION FEATURES
THERMAL MANAGEMENT:
JBL DrivePack systems are cooled by Passive Convection. No fans are used in any part of the thermal
management system. To maintain efficient cooling it is a good practice to assure open space around the
DrivePack units. In the event of excessive exposure to direct sunlight in very hot ambient conditions, it is
possible that the unit may overheat and will automatically shut down to protect itself. When its internal
temperature has returned to within its operating range it will turn back on. To prevent overheating:
ensure adequate cooling and avoid direct exposure of the amplifier panel to direct sunlight by shading it.
OPERATING TEMPERATURE:
The system will remain touchable during quiescent operation and will not provide a burn hazard during
any operating condition.
