-Onkyo PAMC5501 9 Channel Power Amplifier


Rather than simply offering raw power, the Onkyo PA-MC5501 9 channel power amplifier 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 analogue amplifier can provide. Paired with a matching Onkyo pre-pro unit, the Onkyo 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.

A standard integrated A/V receiver has the dual task of both processing and amplifying audio signals, and is therefore susceptible to noise interference from digital circuitry. As a dedicated power amp with all-analogue circuitry, the Onkyo PAMC 5501 suffers no such interference. When partnered with a high-quality pre-pro, such as Onkyo's PR-SC5509, the PA-MC5501 offers all the benefits of pure analogue amplification: a warm, musical, and full-bodied sound.

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.

Like any Onkyo amplifier, the Onkyo PA-MC5501 power amplifier 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 ?F capacitors; large, custom-designed transistors; circuit boards with 70 ?m thick copper foil; and low impedance 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.

The current that drives loudspeakers is delivered by transistors in the output stage circuitry. Although adding more transistors to the output stage increases the output current capability, these extra transistors put added strain on the power supply and generate more heat. When the output stage is required to deliver more power than it is capable of, the top and bottom parts of the waveform are flattened or "clipped". This clipping causes noticeable distortion, even if it occurs only infrequently. The Onkyo PAMC5501's circuit design keeps the transistors separate at the output stage, which means that audio signals are kept free of clipping. Also, with less heat generated, the longevity of the output stage circuitry is enhanced, ensuring that the component stands the test of time.
