ArrayCalc Version 7

d&b audiotechnik launched ArrayCalc Version 7 in the U.S. at the United States Institute for Theatre Technology (USITT) Annual Conference & Stage Expo, which was held March 20 through March 23 in Milwaukee at the Delta Center. Loudspeakers on display included models from the V and E-Series, and several elements from the d&b White range.

ArrayCalc V. 7 performs acoustic simulations with mixed point source and line array system configurations—notably the White range installation products from the xS-Series, with several members of the Black range, and Q, T, and E-Series. d&b states that it simplifies the process of creating remote control workspaces for line arrays as well as point sources, via an export function into the d&b R1 Remote control software.

ArrayCalc V. 7 also offers a new print out section that will include the point source loudspeakers and an array collision detector. The additional algorithms address the requirements for a d&b style simulation and planning tool for a complete installation project, as well as for corporate and A/V rental markets.

In addition, Jason Waggoner and Christopher Kulesa from d&b U.S. training department delivered a well attended education session entitled "Demystifying Audio," which offered a lighthearted look at the fundamentals of audio. "Humor makes the learning easy," says Kulesa. "And as Bob Hope taught us, there's something funny about the sound of a comedian who can sing."

d&b launched the V-Series line array in 2012. The V8 and V12 loudspeakers are 3-way passive designs housing two 10-inch LF drivers, one horn-loaded 8-inch MF driver and two 1.4-inch exit HF compression drivers with 2.5-inch voice coils mounted to a dedicated waveshaping device. They have an 80 and 120 degree horizontal constant directivity dispersion respectively, which is maintained down to approximately 250 Hz. The V-SUB is an actively driven cardioid subwoofer powered by a single d&b D12 amplifier channel and houses two long excursion neodymium drivers in an integrated cardioid setup: an 18-inch driver in a bass-reflex design facing to the front, and a 12-inch driver in a two chamber bandpass design radiating to the rear.

Finally. elements of the E-Series were on display: the portable E4 and E5, plus the E6, which replaced the E3. From the White range 5S, 8S and 12S were shown, with a small flown system of 10AL. A pair of 4S were used to provide a live illustration of the R1 Remote control software.
