Seamlessly integrated, the PX System Power Rack is the heart of the system. Composed of a very powerful Powersoft amplifier module, with PFC and SMPS, and a Powersoft DSP, integrated into Armonia, this power rack is capable of handling a wide range of system configurations with absolute reliability and wide headroom. The system amplifier is based on a Powersoft amplifier module, featuring a Pulse Width Modulation (PWM) block fixed switching frequency design that enables maximum performance, high predictability, and immunity to intermodulation artifacts; all this with an additional and extensive set of protection mechanisms (power limiters, thermal shutdown, short circuit and overload, clip limiter) - there is no quality without reliability! Working at optimum efficiency, little power is wasted and the need for heat dissipation is reduced, resulting in long-term reliability with a staggering 4 x 2000W power output in 4?. Two PXH64 or PXH95 and four PXL118 can be controlled with extreme operational reliability and sound quality. The digital audio processor unit protects and optimizes the entire system, with RMS and PEAK limiters. The DSP has already installed 4 presets: PXH64 FLAT, PXH64 MUSIC, PXH95 FLAT, PXH95 MUSIC. All necessary signal processing features, such as equalization, crossovers, delays, and limiters, are factory-configured for plug �n� play. The system can be fully integrated into the Powersoft Armonia workspace. Seamlessly integrated, the PX System Power Rack is the heart of the system.
