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.

Input Module Controls, Indicators and Connectors

JBL DrivePack® systems are equipped with a modular input bay and input modules are available in three versions in the VERTEC DP Series: the DPIP, DPAN and the DPCN.

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.

NOTE: Please refer to VERTEC DP Series spec sheets for additional features and specifications of the DPIP, DPAN and DPCN input modules.
