According to Rob Wilson, Spectrum Productions chief audio engineer, “The VerTec Series is ideal for covering medium to large audience areas.  Anywhere that (consistent) toneality and audience-area coverage is important, the VerTec series has no equal.  I’ve had the privilege over the last 25 years of working with (sound) systems in nearly every environment all over the world.  This rig is hands down the best sounding, most flexible and easiest to install than anything I’ve worked with.”  The system is especially suitable for presenting live music, spoken word, and full-bandwidth playback material in acoustically difficult venues.  It can work equally well in smaller indoor facilities or over large distances in outdoor situations.

This compact, high power system can easily handle large venues with smooth, uniform speaker coverage, consistent with the performance JBL Vertec users have come to expect.  Due to the 4888’s SPL versus weight ratio, a cluster of four elements can be installed with a single point weighing under 500 pounds.  Eight flown boxes cover over 2000 attendees.  The JBL VerTec line array systems currently in use worldwide are receiving rave reviews regarding their sonic quality, high power output capability and ease of rigging and setup.

VerTec is a truly unique system, not a copy of every other line array currently available.  It is the first line array system to offer so much output capability in such a small enclosure, to employ high-output dual-coil loudspeaker components in an axially symmetrical format, and to provide system users with a flexible, lightweight system that can serve such a wide range of applications.  JBL’s waveguide and R.B.I. (Radiation Boundary Integrator – Patent Pending) are unique acoustical elements with specific acoustical advantages not found in any other system.

The Spectrum Productions system consists of JBL VT4888 top enclosures and JBL 4880 subwoofer enclosures powered exclusively by Crown MA5002 amplifiers.  All cabling is done via a custom Whirlwind/CBI Cable system comprised of industry standard connectors that allow tremendous flexibility and intuitive conductivity.  Streamlined engineering in conjunction with the very fast and flexible JBL Vertec rigging system, enable the entire system to be flown and wired in under two hours.  Complete system processing contains racks of BSS, Drawmer, Yamaha and DBX devices, including the Drive Rack 480, compressors, gates and equalizers.

Power distribution includes Motion Laboratories 200 amp, 3 phase distribution systems outfitted with rugged Hubbell-lock connectors.  The system is pre-engineered with JBL’s Array Calculator for each venue’s use.  Using the Array Calculator, the system designer can accurately predict the sound pressure level at all seats in the venue prior to setup.  This process eliminates the extra costs and time required to adjust the sound system speaker array after installation.

Spectrum Productions anticipates the new Vertec Line Array speaker system to not only bring more flexible options for highly accurate sound to a variety of venues, but also to elevate its already high level of creative production expertise while still maintaining highly competitive price points for its clients.
