Jands distribute JBL Professional V4 DSP preset data for VERTEC loudspeaker system models

Supplier News

At the 123rd AES Convention, JBL Professional introduced new V4 DSP preset data for all VERTEC loudspeaker system models. This comprehensive digital information package includes system drive files for all full-size, mid-size and compact line array elements along with a wide variety of VERTEC subwoofer combinations. The new V4 DSP Preset data for VERTEC loudspeaker system models are available from Jands .

The V4 presets function as a software upgrade to enhance the performance of any VERTEC system, regardless of model or application. Extended high-frequency response, optimised sub/low processing and scalable system design capabilities with consistent spectral balance from one model to the next are hallmarks of the V4 preset libraries.

The V4 DSP preset data provides JBL VERTEC users with a standardised system configuration platform to ensure consistent system performance. Regardless of rental company, DSP platform, speaker models used or system size, sound mixers and professional system operators can now rely upon consistent, refined presets when working on different VERTEC systems around the world.

With the V4 DSP preset data, VERTEC range has the same sonic 'signature'. The VERTEC systems integrate together seamlessly, for example using VT4887A's below a VT4889 array as near field coverage, or VT4888's as side hangs with a main VT4889 system in an arena.

The transition between the different VERTEC models works without interference or perceived change in quality and performance.

A comprehensive year-long programme, the development of JBL Professional’s V4 DSP preset data for VERTEC systems included the use of new proprietary tools not previously available to any loudspeaker system developer.

JBL Engineering’s LDM (Loudspeaker Data Manager) software enabled the premodeling of crossover topologies, corrective section equalisation and time alignment, passband interactions, beamwidth, directivity index, and normalised horizontal and vertical offaxis response.

The V4 DSP preset development included competitive system benchmarking with critical listening and reference system measurements. Indoor and outdoor sessions were staged with all combinations of VERTEC C system models, using spatial-averaging system measurement techniques. For performance, audio criteria were used to achieve optimum limiter settings.

An extended field-testing programme with partners in Asia, Europe, Latin America and North America began with an initial trial during the globally-telecast Live Earth concert event at Giants Stadium, and proceeded at other major concerts and special events including Eric Clapton’s Crossroads Guitar Festival. Upgrades to V4 for VERTEC systems will be installed at premier live-performance venues such as the Gibson Amphitheater at Universal Citywalk, Houston’s Lakewood Church, Los Angeles’ new Nokia Theatre L.A. Live venue and Radio City Music Hall.

John Cooper, sound mixer for Bruce Springsteen, has deployed the new digital data files for his artist’s “Magic” world tour. John Cooper adds that he has used several iterations of VERTEC drive files over the last few years, and with V4 DSP preset data, one can just sit back and mix.

Dave Rees from Deluxe Audio concurs that the V4 preset upgrade to his VERTEC VT4888 system was like getting a new PA for free.

Support for a broad range of signal processing platforms is included with the new V4 DSP presets. The dbx 4800 Loudspeaker Management System was used as a reference development platform due to its extensive filtering capabilities and 96 kHz DSP engine. Programming instructions, preset descriptions for each DSP platform and I/O channel configuration worksheets provide the technical information to use V4 presets by VERTEC system operators.
