FRANKFURT, Germany – Harman Professional's HiQnet Performance Manager software, which debuted at Prolight + Sound 2011, is designed to streamline the system design, setup and tuning process for touring and live performance venue sound reinforcement systems, according to Paul Bauman, director of tour sound product application and application engineering, JBL Professional.
"In touring, time is money," Bauman noted, adding that Performance Manager lets JBL VerTec system engineers "achieve a higher level of performance with more consistent results on a daily basis from venue to venue."
Promising to take the workflow paradigm introduced in System Architect 2 to a new level, HiQnet Performance Manager is fully integrated with JBL's Line Array Calculator II loudspeaker configuration and acoustic modeling software.
The user begins by loading templates of the speaker arrays used in the system, and then runs Line Array Calculator II for each array as part of the initial sound design task of determining how many and which type of loudspeakers are required to cover a given venue.
For each array, Performance Manager automatically loads the passive VerTec or powered VerTec DrivePack DPDA line array configuration into the main application workspace – the first of many automated design processes native to the software application. Loudspeakers can also be manually loaded into the templates if desired.
Once the user defines the required amplifier parameters for the passive loudspeakers within the arrays, Performance Manager automatically loads the correct number of Crown Audio VRACK or other user-determined amplifier racks into the audio system.
The software then associates the amplifier outputs with the bandpass crossover inputs for the selected array and programs the amplifiers with the correct JBL preset data, along with gain shading and EQ parameters determined in JBL's Line Array Calculator II as part of the modeling process to optimize sound pressure level and frequency response over the defined audience geometry.
"HiQnet Performance Manager greatly simplifies loudspeaker preset management as well as power amplifier networking, grouping, monitoring and control," added Brian Pickowitz, market manager, Crown Audio International, calling it "a huge timesaver for the touring sound engineer."
Representations of the bandpass inputs for each loudspeaker section are overlaid onto the arrays, helping users visualize the array configuration, whether JBL DrivePack-powered or driven by external Crown Audio power amplifiers.
Performance Manager software also promises to simplify system networking configuration – the user can simply drag and drop devices discovered on the network onto the pre-configured devices within the Performance Manager workspace to synchronize all addressing and parameter values.
In addition, the Performance Manager graphical interface provides embedded control panels for array calibration, time alignment and system EQ which utilize input section digital signal processing resources available in either Crown I-Tech HD power amplifiers or JBL DrivePack-powered loudspeakers with DPDA digital audio input modules. Input attenuation, equalization, delay settings and bandpass controls are all accessible within the main application workspace, along with grouping and solo/mute functionality for system testing.
Once system tuning is complete, Performance Manager's Show Mode display can assist with the actual live performance offering appropriate adjustment control ballistics for equalization and dedicated monitoring interfaces for levels, speaker loads, thermal conditions and AC power requirements. The workspace for all stages of Performance Manager's workflow has a common design motif, with monitoring functions overlaid on top of the same loudspeaker bandpass representations within the workspace, making visualization easier and more consistent across various workflow screens.
