Amplificator Onkyo PA-MC5501

9-Channel Amplifier

Transcendental Performance from Flagship Power Amplifier

Rather than simply offering raw power, the PA-MC5501 is engineered to deliver superior dynamic response and outstanding signal purity. Onkyo’s highly efficient push-pull amplification and WRAT suite work to minimize interference, stabilize the voltage, and boost the current across the unit’s electrical system. Components such as the toroidal transformer, large capacitors, and heavy-duty transistors are all designed to handle very high loads. Audiophile-grade parts—such as gold-plated speaker posts and XLR inputs—are used throughout. The result? Instantaneous response to signal gains, extremely low levels of distortion through the dynamic range, and the sort warmth and clarity only a top-shelf analog amplifier can provide. Paired with a matching Onkyo pre-pro unit, the PA-MC5501’s nine channels and bi-amping capability offer extraordinary set-up flexibility to bring you the ultimate in THX® Ultra2™-certified surround sound.

THX® Ultra2™

Certified When a home cinema component receives THX certification, it is your guarantee that it will accurately present movies the way they were mixed by the filmmaker in the studio. In the case of THX Ultra2 certification—the ultimate benchmark for home audio performance—a power amplifier must offer high-quality, high-output performance for multi-channel playback in large rooms. Among the strict criteria that THX uses for judging the quality of a power amplifier are measurements of continuous power output, distortion levels, and heat generation.

Audiophile Design and Components for High-Power Performance

Like any Onkyo amplifier, the PA-MC5501 is designed to deliver ample power to your speakers, regardless of fluctuations in impedance. What makes the PA-MC5501 our top power amp, though, is the extra attention to parts and construction. A massive toroidal transformer; two 22,000 µF capacitors; large, custom-designed transistors; circuit boards with 70 µm thick copper foil; and lowimpedance copper bus plates all work in concert to enhance the power and fidelity of your audio sources. Housed in a highly rigid, anti-resonant steel-plate chassis, the PA-MC5501 also sports audiophile-grade connections: gold-plated XLR inputs; machine-tooled solid brass RCA inputs; and gold-plated, banana plug-compatible speaker posts. From input to output, signal purity is maintained at every stage.
