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 ultra-compact, high-
power JBL DPC-2 amplifier module features Crown’s patented Dual-Bridged Technology

amplification circuitry and is integrated to the back of each DP-compatible loudspeaker enclosure,
creating a seamless electro-mechanical system that offers both convenience and portability along

Drive loudspeaker. Electrical power transfer to the transducer is optimized for maximum system
performance. The DrivePack includes onboard DSP functionality and includes lighted indicators
displaying system status during opertion.
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
4 Ohms or 8 Ohms for low and mid frequency channels, and 8 or 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 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.
