Edison, NJ (July 24, 2017)—Loudspeaker manufacturer RCF has introduced FiRPHASE DSP—an advanced FiR filtering technology—for a wide range of its products, including HDL6-A and HDL50-A line array systems, TT45-CXA monitor, ART 3 Series, ART 7 Series and HD Series two-way composite speaker cabinets. Other RCF products with proprietary RDNet control software will be able to be upgraded through firmware updates.
According to RCF, the FiRPHASE DSP updates will ultimately provide “more transparency, clarity and linearity” in these and new speaker products.
RCF’s FiRPHASE technology monitors and adjusts the minute delays caused by non-time-aligned transducers, providing a reported end result of 0 degrees linear phase.
“The algorithm corrects phase and amplitude by taking into account the weak points of the transducers and the resonances or cancellations created by the transducer,” explains RCF promotional materials, inverting the loudspeaker’s phase without affecting amplitude equalization. “This technique allows for increased control of phase at lower frequencies, reaching a higher resolution than industry standard FIR filters have permitted.”
