SONIC PRO®theDHThe series of high-end digital power amplifiers is a full-function digital power amplifier specially designed for high-end performances and fixed installation projects. It combines analog,AESdigital signals,DANTENetwork audio signals are organically combined to realize mutual backup of analog and digital signals; internal implantation of the machineSONIC PRO®Audio high-precision multi-channelDSPProcessor, equipped with the latestFIRDigital filter increases the accuracy of frequency division adjustment in the audio system, thereby bringing the effect of the entire sound reinforcement system to a new height; the machine adoptsAPFC(Active Power Factor CorrectionActive power factor correction technology)bindingSONIC PRO®theSFOSTechnology (wrong frequency oscillation synchronization technology) solves the instability caused by frequency resonance of high-power multi-channel digital amplifiers that have plagued the industry for many years. At the same time, we have applied the reverse electrodynamic technology of recycling speakers to the latest digital amplifiers, making The efficiency of this series of digital amplifiers has been greatly improved and the reserve power has been increased, thus making the stability of the equipment and sound quality the best in the industry!
