INDICATORS
6. PEAK
Red LED, detects excessive input signal. The LED illuminates when overload at any point is detected.
7. SIG
Green LED, detects input signal, illuminates above the threshold set at -70 dBu.
8. POWER
Blue LED - located near voltage select switch, illuminates when AC power is applied and unit is ready for operation.
CONNECTORS
9. Audio In
F-XLR Active 20K Ohm Balanced, 10K Ohm Unbalanced.
Pin 2 Hot (Positive voltage produces outward cone motion of L.F. Transducers).
10. Audio Out
M-XLR Passive Audio Pass-through.
Pin 2 Hot (Positive voltage produces outward cone motion of L.F. Transducers).
11. AC LINE INPUT
Blue Neutrik PowerCon
®
NAC3MPA A-type air tight twist-lock chassis connector for AC power inlet. The
mating blue cable connector is keyed and will insert in only one orientation. Electrical connection is made
when the AC plug is fully inserted and twisted clockwise until locked into position.
12. AC LOOP OUTPUT
Gray Neutrik PowerCon NAC3MPB B-type air tight twist-lock power outlet connector is provided to loop AC
power through to additional units.
The mating gray outlet cable connector is keyed and will insert in only one orientation. Electrical connection
is made upon fully inserting the AC plug and twisting clockwise until locked into position.
To accomplish loop-thru AC power connections, simply attach a PowerCon jumper cable from the gray
connector of the first loudspeaker system to the blue connector of the second, etc. Blue Inlet and Gray
Outlet connectors are not interchangeable.
CAUTION:
Looping more than three DPC-2 systems together is not recommended! Do not exceed 80%
current rating of any AC connector at any time! Refer to AC Power Rating Tables in this docu-
ment for current draw information.
AUDIO SIGNAL DISTRIBUTION
Connecting source audio signals to the input modules on JBL DrivePack systems is similar to daisy-chaining
multiple external amplifier channels together.
Assuming an output device source impedance of 100 Ohms and a 10:1 load to source ratio, up to 20 JBL
DrivePack units typical can be linked together on one output source without using a distribution amp.
