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

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.
