DPDA – HiQnet Networked Input Module with AES Digital Audio
and BSS Omnidrive HD Signal Processing
See Figure 1b
The DPDA Input Module can be used as a retro-fittable sub-assembly with any JBL DrivePack-equipped
speaker system. Upgrading to the DPDA module provides powered loudspeaker system users with AES/
EBU digital audio capabilities, the sonic benefits of advanced signal processing features, and a variety of
input and connectivity options.
Its onboard 100 Mb Ethernet networking switch with daisy-chain capability allows for Remote Control and
Monitoring via HiQnet System Architect™ software. Additionally, a rotary mechanical encoder switch allows
for array identification and box positioning, up to 99 different speaker positions within each of 99 different
speaker arrays or groups.
Twenty, type-selectable input filters (10 System and 10 Guest filters) are available for system equalization
along with user-adjustable input delay of up to  seconds and sub filter access (user-adjustable low pass
filter for subwoofer systems; high pass filter for full-range systems). Signal generator functions (sine wave,
swept tone, pink or white noise) are available to facilitate system testing and up to fifty presets can be stored
internally.
In addition, Master Control Panels and Master Monitor Panels within System Architect software allow for
convenient grouping of control and monitoring functions for multiple JBL DrivePack enclosures with DPDA
input modules. This functionality provides a powerful remote control/monitoring interface that is especially
useful when working with larger multi-box line array or subwoofer systems.
The HiQnet System Architect™ software user interface provides remote access to the controls, displays and
digital speaker preset files available in the JBL DrivePack® Software Control Panel
