The JBL DPDA-VT4882 DPDA Input Module can be used as a retro-fitable sub-assembly for JBL VP7215/64 DrivePack-equipped speaker systems. 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.


It has an onboard 100 Mb Ethernet networking switch with daisy-chain capability, which allows 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 50 presets can be stored internally.

Additionally, as part of the system's powerful remote control/monitoring interface, a self-diagnostic mode for speaker load monitoring verifies electrical transfer functions and impedance loads with the simple push of a button.
