RCF unveils PAcalculate version 1.3.2
RCF unveils PAcalculate version 1.3.2
The latest version of the PAcalculate Android and iOS app from RCF introduces several new features for modelling subwoofer arrays. The software comprises over 30 calculators, reference info and utilities for sound reinforcement and lighting professionals.
Version 1.3.2 boasts in-line and broadside subwoofer array calculators. The former allows for simulation of end-fire and gradient arrays, including an obscure four-element topology originally proposed by 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. Frequency response graphs (front-to-back ratio as well as multi-angle responses), an isobar display, polar plots and coverage maps provide a comprehensive set of graphics for analysis of design alternatives. Up to 96 elements (sound sources) can be simulated, 48+48 in L-R mode. A table is displayed with coordinates and settings (delay, polarity) that can be emailed for reference. A footer alerts the user if the specific configuration requires delay tuning on top of the results calculated (such as for gradient arrays).
PAcalculate can be downloaded for free and supports eight different languages, including English, Spanish, Italian and Chinese.
Over a quarter of a century on since its original launch and RCF continues to evolve the ART series of portable loudspeakers. Combining all of ART 9-A characteristics together with an onboard digital mixer, Bluetooth and advanced control capabilities, the ART 9-AX is the latest addition to the family. Operating solo or paired with other speakers and subwoofers in wired or wireless mode, ART 9-AX’s available functions and parameters are accessible from the rear panel via a capacitive colour touchscreen with encoder knob. Alternatively, a dedicated app can be downloaded to iOS and Android devices. RCF LiveRemote allows full control of the internal ART 9-AX engine to recall and save presets, set desired volume levels, perform tuning and adjust EQ, reverb, compressors and FX settings. Adjustments can be made to True Resistive Waveguide, FiRPHASE and Bass Motion Control. The 2,100W biamplified Class-D electroacoustic design also incorporates 48V microphone preamps and line inputs, an internal six-channel digital mixer with advanced DSP, Bluetooth audio input and remote control for both single and dual paired speakers.
Designed for use as a standalone speaker, flown, coupled with another NX 985-A or combined with a subwoofer, the NX 985-A features a 1.75-inch neodymium compression driver with a constant directivity waveguide, 8-inch midrange on a phase-coherent waveguide and a 15-inch LF woofer. Offering consistent 100° x 60° coverage and operating within a 40Hz–20kHz (–10dB) linear frequency response, the three-way design can produce a maximum SPL of 138dB. Loaded with a biamplified 2,100W Class-D amplifier, the NX 985-A also incorporates FiRPHASE and Bass Motion Control DSP processing. Finished in a durable outer texture, the wooden cabinet with ergonomic handles on each side can be coupled for improved coverage, in addition to being flown or truss-mounted using the included M10 rigging points and accessories.
Designed as a multipurpose, two-way, full-range series of loudspeakers suitable for a wide range of sound reinforcement applications including stage monitoring, RCF has launched the Compact A Series. The Compact A 10 combines a 10-inch woofer, a 1.75-inch compression driver and a constant directivity True Resistive Waveguide to produce 100° x 60° coverage. The 16.2kg polypropylene composite cabinet benefits from M-brace internal reinforcement, for secure flown, pole-, wall- or truss-mounted installation using the multiple rigging points and available accessories. The 350W power handling model can produce up to 128dB SPL, within a 60Hz–20kHz (–10dB) frequency range.
Based on the same build, components and dispersion characteristics, the larger Compact A 12 and A 15 models distinguish themselves with 12- and 15-inch woofers respectively. Weighing 18.8kg, the 400W Compact 12 A version can produce deeper bass to 55Hz (–10dB), while the 450W Compact 15 A is capable of producing 130dB SPL down to 50Hz (–10B).
