The Yamaha PC4801N amplifier features an extraordinarily solid low end, rich mid-range, and superbly defined highs. It also delivers fast response and exceptional stability even in the face of serious power supply limitations. Refinements throughout this model make this amplifier the new benchmarks for quality, reliability, and versatility in professional applications. Maximum sound quality with minimum distortion for a new dimension in powerful, clear sound. From the start, the new Yamaha PC4801N had a lot to live up to. As the next generation in Yamaha’s flagship PC lineup, it had to deliver the same exceptional standard of clear separation and rapid response while taking sound quality to the next level. Yamaha audio engineers went to work examining every detail of sound quality. Which led to breakthrough-level innovation in circuitry and internal wiring. Meticulous part selection — including environmentally friendly lead free parts — and innovative combinations. It also includes new circuit board mounting methods to absorb unnecessary vibrations. Clear and transparent, yet powerful and robust. The Yamaha PC4801N features dynamic, deep, detailed sound with exceptional balance — the kind of performance that "runs in the family".
