USA - Maryland Sound International (MSI) has recently purchased an additional 36 JBL Vertec VT4888DP-AN midsize powered line array loudspeakers. Located in Baltimore, Maryland, MSI has been an audio production and services company since 1966 and is now celebrating its 40th year in business. MSI provides numerous services, including special event production, concert touring packages, system design and engineering, and system analysis and construction.

MSI has recently been the sound company of choice for diverse and prominent acts like Neil Diamond, Josh Groban and Dream Theater. MSI has provided live sound for high-profile events including the dedication of the National World War II Memorial in Washington D.C., the Presidential Inaugurations at the US Capitol in 2001 and 2005 and New York City's Times Square New Year's Eve.

Vertec line arrays have played a significant role in MSI's continued success. MSI was one of the first top-tier rental companies to adopt JBL Vertec systems, and is now one of the world's largest owners. "Over the years, we have found that there is nothing that the Vertec system hasn't done that we've needed it to do," said MSI founder and owner Bob Goldstein. "In deciding to offer new options for our broad client base, we've now added the new powered Vertec DP Series."

Each of MSI's new powered VT4888DP 3-way mid-size line array elements is equipped with JBL DrivePack technology, comprising an advanced integrated electronics package pre-configured from the JBL factory. The JBL DrivePack features Crown's exclusive BCA (Balanced Current Amplification) technology, incorporating Class I circuitry. State-of-the-art internal feedback circuits enable the JBL DrivePack to set a new standard for performance in digital amplification, with lower noise and distortion specifications than other high-power switching amplifiers in the pro audio market. The JBL DrivePack units include an auto-sensing Universal Power Supply and a fan-free, passive, cooling design. MSI's new system is fitted with JBL's optional network input modules that allow Vertec DP Series systems to link seamlessly into Harman Professional's revolutionary new HiQnet system, via industry-standard Cat 5 cabling. MSI relies on custom ruggedized, road-ready cabling systems developed in coordination with Link USA to deploy its new powered, networked sound system.

Since purchasing the VT4888DP-AN, Maryland Sound crews have deployed the new system for a number of concerts and civic and corporate events. "We like the VT4888DP-AN system for many reasons, particularly for its flexibility," Goldstein said. "We've used them in several different applications, and they have performed extremely well." Senior engineer Art Isaacs observes that the new Vertec DP Series system is the perfect solution for the increasing number of corporate events being handled by the company. "Clients in that market don't want to see the sound, they just want to hear it," advised Isaacs. "The integrated, self-powered solution is ideal in those situations. And regarding how the system sounds, our event clients are always happy."
