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, 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 100-120VAC or 200-240VAC 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 2 seconds.The system is ready for operation when the Green Ready LED on both the AC Input module and DPIP module is steadily illuminated.
