Onkyo 100KIT Pre and Power Amplifier Home Theatre Package

Onkyo PR-RZ5100 11.2 Channel THX Network Home Theatre Processor features HDMI 2.0, THX Ultra2, 8 HDMI inputs, Dolby Atmos® and DTS:X™.

Update your lovingly assembled home theatre and join the object-based sound revolution with a flexible and sophisticated controller capable of delivering a full-scale multidimensional surround-sound experience without caveat or compromise. DTS:X™ and Dolby Atmos® formats are decoded and sent to your power-amp and floorstanding/in-ceiling speaker layout with utmost fidelity through RCA or XLR pre-outs, unlocking a truly immersive theatre experience. Premium DACs and VLSC™ assures stunning purity for Hi-Res Audio, such as 11.2 MHz DSD, while separate digital/analog circuitry prevents interference on analog sources. Together with comprehensive wired and wireless multi-room A/V capabilities, app-based streaming via Google Cast™, Wi-Fi®, and AirPlay®, and the latest HDMI® connections, this beautifully crafted centrepiece boasts every convenience to smooth the transition to next-generation entertainment.

Combined with a THX®-certified amplifier, the PR-RZ5100 controller’s THX® Ultra2™ Plus certification assures distortion-free Theater Reference Volume in large home theatres. Certified products are subjected to the industry’s toughest bench-tests to satisfy THX® requirements for audio performance.

No matter how good the DAC, pulse noise is an inevitable consequence of digital-to-analog conversion. VLSC (Vector Linear Shaping Circuitry) compares vectors from the input/output signal and uses that information to erase digital noise. A pure, noise-free analog signal is fed to your amps, resulting in improved detail resolution and clarity.

With 11.2 pre-amp channels, you can let your speakers deliver a complete multidimensional movie experience in your home theatre through a 7.2.4 layout. Dolby Atmos® and DTS:X™ unlock sound from conventional channels and free audio to move above and around the audience for a thoroughly captivating and immersive movie experience.

AccuReflex—part of the AccuEQ room calibration suite—phase-matches height and floor-standing speakers for transparent and seamless reproduction of object-based sound. AccuEQ optimizes the entire system to suit your space without affecting front-speaker characteristics for pure stereo listening.

Onkyo PA-MC5501 9 Channel Power Amplifier is engineered to deliver the 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.

The PA-MC5501 employs proprietary Onkyo technologies to ensure optimal audio performance.

Although negative feedback (NFB) is a cheap way to reduce noise at lower frequencies, there is a price to pay in terms of audio quality: NFB can severely inhibit an amplifier’s ability both to respond to large signal gains (for example, in a fortissimo passage) and to produce sound at high frequencies. That’s why the PA-MC5501 has a low-NFB design with audiophile-grade, close tolerance components at critical points in the signal path. This design allows it to achieve a frequency response out to 100 kHz for high-resolution formats such as DVD-Audio and Super Audio CD, as well as for regular CDs, DVDs, and other music sources.

If an amplifier’s ground potential (voltage) fluctuates during playback, noise is likely to result. In an open-loop circuit design, where all circuits are connected to the power supply via a single loop (as on many amplifiers), the noise is compounded. To avoid this, the PA-MC5501 employs a sophisticated closed-circuit design in which each circuit has a separate link to the power supply— this helps to cancel individual circuit noise and keep the ground potential free of distortion.

When an amplifier outputs an audio signal, the connected speakers accumulate energy, reflex, and send energy back to the amplifier. The amplifier must then immediately cancel the speakers’ reflex energy and instantaneously send out the next signal. The same high current required to achieve this is also necessary to handle speaker impedance fluctuations, which can force an amplifier to provide four to six times its usual current load. The PA-MC5501’s instantaneous current capability ensures that audio output is not affected by power limitations.

In order to handle high levels of instantaneous current, the PA-MC5501 incorporates several key design features.

Found only in high-end amplifiers, this ultra-sensitive circuitry reduces distortion by maintaining voltage stability and enhancing transient response.

The PA-MC5501 features an improved board design with short signal pathways to reduce electromagnetic interference. The board is also designed to optimize power delivery to the speaker drivers.

The amplifier design also incorporates a symmetrical alignment of power devices for each channel. With channels built to be identical in terms of electrical, structural, heat-generating, weight, and electromagnetic characteristics, errors in stereophonic playback are minimized.

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-analog circuitry, the PA-MC5501 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 analog 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 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 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 PA-MC5501’ 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.
