RCF sponsors PAcalculate app update
- Details
Europe - RCF has introduced PAcalculate version 1.3.2, an Android and iOS app for mobile phone or tablet with over 30 calculators, reference info, and utilities for sound reinforcement and lighting professionals.
The new version boasts in-line and broadside subwoofer array calculators. The former allows for simulation of end-fire and gradient arrays, including an obscure 4-element topology originally proposed by the very Harry Olson. The broadside section features independent mechanical and electronic arcing and steering, with the possibility of adding a gradient line, or several end-fire lines, a type of subwoofer configuration that has become widespread to achieve wide uniform subwoofer coverage with reduced stage leakage.
