OverviewJBL DrivePack input modules are used to implement crossovers, equalization, time alignment, and protection for the attached speaker system. Speaker-dependent DSP settings are not user-configurable from any version of the input module. The following options are available for connectivity, audio signal path and control functionality.
JBL DrivePack® standard models are factory configured with the DP dbx® input module. Designed and manufactured by dbx®, the standard DPIP input module is a non-network plug-and-play version and features analog audio inputs and sophisticated inboard digital signal processing technology. Precision band-pass limiting, pre-equalization filters and automatic self-test functions ensure optimized performance. Front panel controls include a 32-position detented rotary attenuator calibrated in 0.5 dB steps which provides a 16 dB range of control. This can be useful for setting up down-fill shading or overall system gain structuring. Another feature is the "Enable Subwoofer Filter" button. This is a momentary-contact type switch which enables or disables the selected function. On sub-woofer applications, the low-pass frequency is set to 80 Hz. For full-range systems used with sub-woofers, the high-pass is raised to 80 Hz.
In addition to all of the features included on the standard input module, the DPAN adds 100 Mb Ethernet networking functionality and HiQnet compatibility. It enables remote control and monitoring via HiQnet Audio Architect™ software. Network Control and Monitoring is enabled by the JBL DP-SCP (DrivePack Software Control Panel) supplied within HiQnet Audio Architect. Network capabilities include monitoring of status, input and output levels, clipping, temperature, load faults and gain reduction. Additional control features available in software include load supervision, dynamic processing, ten internal pre-e.q.filter presets, delays, inboard noise and sine-wave generators, network device event logging, and user alert messaging.
In addition to all of the features included on the DPAN, the DPCN input module adds CobraNet® to the mix and offers the ability to direct up to 64 audio channels on one network, with digital audio and remote control and monitoring via Ethernet combined on a single cable. DPCN includes the option to use an analog input as a backup audio source providing you complete reliability and flexibility to cover any situation. With HiQnet Audio Architect providing the software user interface, the HiQnet communications protocol provides remote access to digital speaker preset files in the JBL DrivePack. As with the DPAN, user-addressable features include ten internal pre-e.q. filter presets, up to 2 seconds of delay per channel, inboard noise and sine-wave generators, network device event logging, and user alert messaging.
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 Audio 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.
