Each JBL DrivePack is equipped with a modular input bay that can accept several different options. The full-featured DPDA (DrivePack Digital Audio) Input Module provides the sonic and performance advantages of BSS OmnidriveHD signal processing with FIR/IIR filters and LevelMax multi-stage limiting, plus AES/EBU digital audio input and analog audio backup capabilities. A built-in 100MB Ethernet switch enables remote control and monitoring functionality with Harman’s HiQnet System Architect software. As a basic non-networked option, the simpler DPIP (Input) module features analog audio inputs and onboard dbx digital signal processing technology. The DPAN (Analog audio) input module and the DPCN (CobraNet) digital audio input module support existing systems in the field, and also feature HiQnet network capabilities. Both include Crown’s digital signal processing technology with precision bandpass limiting, pre-equalization filters and self-test functions. All modules are fully interchangeable to support retrofit capabilities and an upgrade path when desired by system owners.
