JBL DPDA Devices - HiQnet Network Input Module
with AES® Digital Audio
JBL DrivePack®

         

OVERVIEW

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 2 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

INDICATORS

1) CROSSPATCH

If active, AES audio and HiQnet/network is daisy-chained via Ethercon/RJ45 out connector.

2) AES LOCK

If active, indicates AES sync has been detected and input card has locked to it.

3) FAULT
Red LED illuminates during any fault condition.  
4) CLIP 
Red LED indicates clipping  at any point is detected.
5) SIGNAL  
Green LED indicates a detected input signal above the threshold set at –70dBu.  
6) OVER TEMP
Orange LED illuminates during thermal limiting:
7) READY  
Green LED illuminates when the system is ready for operation.  
8) DATA
Yellow LED indicates network activity

CONTROLS

9) ENABLE ALT PRESET

a) Press and hold for 3 seconds.

b) When LED is active, the alternate preset with 80Hz high pass has been recalled or loaded. On subwoofers, the preset with 80Hz low pass is recalled.

10) ARRAY ID MECHANICAL ENCODER
a) If “00”, the software will automatically determine the array IDs as they are wired.

b) User can manually set all speakers to be in the same array or cluster via the rotary dial.

11) LOUDSPEAKER POSITION ID MECHANICAL ENCODER
a) If “00”, the software will automatically determine the position of the speakers within the array via their network interconnections
    (speakers must be daisy-chained for software to determine their location).

b) User can manually determine the position of the speakers within the array via the rotary dial.

Note: Array ID/Loudspeaker ID Examples
Example A: "00 00"  would be complete auto ID mode.
Example B: "01 01" would be Array ID #1, speaker on position #1 (top)  etc.

CONNECTORS

12) NETWORK 100MB ACTIVITY OUTBOUND 
The Orange Activity LED indicates activity on the outbound Ethercon connection.
13) NETWORK 100MB ACTIVITY INBOUND 
The Orange Activity LED indicates activity on the inbound Ethercon connection.
14) AUDIO OUT

a) Analog mode: passive pass through

b) AES mode: 110 ohms, buffered

15) AUDIO IN

a) Analog mode: Balanced , 20Kohms input impedance

b) AES mode: Differentially balanced, 110 ohms input impedance
