Introduction to the
JBL DrivePack 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.
The DrivePack is attached to the back of each DP-compatible loudspeaker enclosure, creating a seamless
electro-mechanical system that offers both convenience and portability along with the unmatched reliability,
accuracy and superb sound of JBL loudspeakers. The DrivePack includes onboard DSP functionality to
communicate readiness and operational status, including a self-test cycle and lighted indicators for fault
detection upon power-up.
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 Ohms, 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 connect an AC power
source to the AC Power module via the Neutrik PowerCon™ inlet connector, and a full range line level audio
signal to the Input module via the AUDIO IN XLR connector.
Upon initial power-up of the DrivePack, the Blue Power LED will illuminate and the Green DP Ready indicator
(located to the left of the input module input level control) will flash during the boot-up and AC line auto-
select soft-start process. The JBL DrivePack is equipped with Auto-Sensing Universal AC Voltage Selection
and can operate anywhere in the world that has an available 100-10VAC or 00-0VAC power source. On
the power-up sequence the JBL DrivePack® input module senses line voltage and sets the high voltage line
select relay within about seconds. The system is ready for operation when the Green Ready LED on both
the AC Input module and DPIP module is steadily illuminated.
