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.
