AC Power Module
POWER Indicator:
Blue LED – located near power inlet lights when AC power
is applied.
Amp READY Indicator:
Green LED near power inlet, ON during normal operation,
long pulse during sleep mode.
Sleep Mode:
If audio input signals are not detected for 2 hours, the
amplifier will go into sleep/standby mode; the amplifier
output section is turned off while the supply powering the
DP Input Module and DSP logic remains active. This mode
reduces current draw and heat loss. While in sleep mode
the READY indicator pulses slowly. Recovery from sleep
mode is instantaneous when an audio signal is detected
.
Thermal Management:
JBL DrivePack systems are cooled by Passive Convection. No fans are used in any part of the thermal
®
management system. To maintain efficient cooling it is a good practice to assure open space around the
DrivePack units.
Operating Temperature:
The system will remain touchable during quiescent operation and will not provide a burn hazard during any
operating condition.
