ProAudio Review - May 2008 - (Page 18) LIVE | Feature LINE ARRAY Continued From Page 17 ever having to use the EAWPilot software package,” says Butler. “So people who aren’t as PC savvy or who chose to leave their PC at home can utilize three back panel switches that allow for basic control and tonal adjustment. The next step up involves utilizing EAW Pilot to connect with the system through its on board proprietary network called U-NET to adjust front-end EQ and tailor the high frequency EQ to adjust for air loss effects–typical functions that an engineer might be used to. The third level is to actually get into each individual loudspeaker enclosure and adjust delay and EQ.” While the loudspeaker systems lighten their loads, the live sound system overall is The new self-powered, compact EAW NTL720 line array in tandem with the KF730 Series small-format line array becoming more streamlined, thanks to the increased use of digital consoles, wireless mic systems, PC-controlled amp racks and modeling software, among other components. Tuning a room via a laptop PC offers greater control, consistency, and efficiency, while CAT5 cabling, Ethernet connections, and Fiber Optic wires lessen the number of cables and keep computers running at top speed. “It’s getting to the point where you can connect everything with CAT5 cables and define how you want all of your audio channels routed through the computer screen via the DSP,” says Butler. With that in mind, manufacturers have to ensure that their products network properly with a variety of digital components. In coordination with sister company Crown, JBL’s R&D Department developed DrivePack technology for use in creating integrated, powered loudspeaker systems, as well as network input modules to allow certain JBL products to link into parent company Harman Pro Group’s HiQnet networking protocol. “We have networking embedded as an integral part of the system,” says Scheirman. “Ethernet connectors are built into the signal processing module, and all of the different control and monitoring parameters of the loudspeaker systems can be addressed with standard information technology, such as CAT5 cabling, and treated as a single network. Literally hundreds of devices can be controlled and monitored simultaneously over the same network with 18 | ProAudio Review | May 2008 www.proaudioreview.com http://carvinproaudio.com http://carvinproaudio.com http://www.proaudioreview.com
