In pursuit of providing the highest sound quality and in-vehicle listening experience, Pioneer Electronics (USA) Inc. today released its Premier PRS-A900 4-channel reference amplifier and, in turn, redefines “state-of-the-art” with regard to mobile amplification. Following an unlimited design philosophy of performance and quality regardless of cost, this new amplifier surpasses the standard set by its spiritual predecessors, the critically acclaimed in-car amplifiers of the Pioneer Optical Digital Reference (ODR) system.
“Our engineers painstakingly over-engineered each section of the PRS-A900 to produce one of the most accurate and musical automotive amplifier ever created, while at the same time achieving excellent dynamics, power output or reliability. Virtually every aspect of the PRS-A900, from the components on the circuit board to the bottom of the chassis, were designed for reproducing incredible sound quality,” said Larry Rougas, vice president of marketing and product planning for the mobile business group of Pioneer Electronics (USA) Inc. “What resulted is an amplifier that can satisfy even the critical listener.”
The PRS-A900’s reference audio quality begins with an independent, symmetrically isolated circuit board intended to prevent noise, both in the form of electrical interference and physical vibration, from entering the audio signal path. Copper shielding bars in a T-shaped pattern are used to isolate key components from the internal power supply section, blocking any potentially radiated electrical noise that may distort the signal. The copper shield layout design is also utilized in the output section, to isolate the left and right channels preventing any cross talk interference.
All internal components used in the PRS-A900 were critically tested and selected for their performance and quality. Pioneer engineers conducted hundreds of listening sessions to evaluate each component selection, and even required specially designed, made-to-order capacitors when all others failed.
In order to shorten the signal path and minimize the potential for signal degradation, the PRS-A900 is a filter-less design which eliminates any crossover filters or internal equalization. This simple and clean circuit design ensures that the PRS-A900 acts only to “amplify” the signal, not to alter or “color” the sound in any way. The result is pure, clean, and powerful music.
Every detail of the amplifier including the bottom cover is intended to isolate the pure audio signal and reject noise. The use of a copper bottom cover further shields the circuit from magnetic conduction noise, while its embossed H shaped stamping eliminates resonance and physical vibrations from producing even the slightest audible noise.
The Premier PRS-A900 amplifier is now available for discerning audiophiles at a suggested price of $1,500.
