Pioneer Introduces PRS-A900 High-End Mobile Amplifier

Business Wire -- Pioneer Electronics has just released their new 'no holds barred' mobile amplifier, the PRS-A900, designed to appeal to critical listeners. According to Pioneer, the amplifier follows an unlimited design philosophy of performance and quality regardless of cost and surpasses the standard set by its predecessors, the critically acclaimed in-car amplifiers of the Pioneer Optical Digital Reference (ODR) system.

Larry Rougas, Vice President of marketing and product planning said “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. 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.

Here are the specifications for the new Pioneer PRS-A900:
