WRAT (Wide Range Amplifier Technology)

The PA-MC5500 employs proprietary Onkyo technologies to ensure optimal audio performance.

Benefit 1: Uncommonly Low Negative-Feedback Design—Get cleaner sounds on program peaks

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-MC5500 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.

Benefit 2: Closed Ground-Loop Circuits—Enjoy greater maximum volume without distortion

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-MC5500 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.

Benefit 3: HICC (High Instantaneous-Current Capability)—Experience audio with greater dynamics

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-MC5500’s instantaneous current capability ensures that audio output is not affected by power limitations.

HICC (High Instantaneous-Current Capability)

In order to handle high levels of instantaneous current, the PA-MC5500 incorporates several key design features.

(1) Push-Pull Amplification Design with Three-Stage Inverted Darlington Circuitry
Found only in high-end amplifiers, this ultra-sensitive circuitry reduces distortion by maintaining voltage stability and enhancing transient response.

(2) Improved Board Design
The PA-MC5500 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.

(3) Symmetrical Layout
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.

All-Analog Circuitry Unaffected by Digital Noise

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-MC5500 suffers no such interference. When partnered with a high-quality pre-pro, such as Onkyo’s PR-SC5507, the PA-MC5500 offers all the benefits of pure analog amplification: a warm, musical, and full-bodied sound.

THX® Ultra2™ Certified

When a home theatre 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-MC5500 is designed to deliver ample power to your speakers, regardless of fluctuations in impedance. What makes the PA-MC5500 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 foi; 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-MC5500 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.

Discrete Output Stage Circuitry to Inhibit Audio Interference

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-MC5500’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.

Up to 90 Day Returns!

Returns are easy and flexible. We will accept returned goods up to 90 days from purchase with the following restrictions as summarised below. For more details please read our Terms & Conditions of Sale, a link is shown at the bottom of the home page.

Changing your Mind
It's OK to change your mind but please be aware that all goods must be returned in as new, unused and re-saleable condition. This means that all packaging must be intact, all accessories are complete in their original wrappers and any free items are also returned with the goods. Essentially the product must be returned in the same condition as you would expect to receive a new unit in. In all cases the cost of returning the goods will be the customer's responsibility. All faulty items must be returned complete and will be repaired under the manufacturer's warranty.

 

How we Handle Returns
Depending on how long you have had the goods there are different options availble to you. In the case of faulty items, if the item fails due to a manufacturing fault between 1 and 28 days from delivery we will exchange it for a brand new one of the same model. Any items which are found faulty after 28 days from delivery will be repaired under the manufacturers warranty. For returns where you have changed your mind, please find our policy below:

Returns

Exchange
This is were you return your item and we will exchange it for another item of equal or higher value. If the item you wish to change to is of higher value you only pay the difference. If the item is of a lower value we will issue you with a credit note for the difference which you can spend with us at a later date.

Credit Note
This is where you return your item and we issue you with a credit note which you can use against another purchase with us.

Refund
This is where you return your item and we issue a refund back to the same method you paid with. e.g. the same credit card. This is not available after 14 days, only exchange or credit note is available after 14 days.

25% Restocking Fee
If your item is returned to us between 29 and 90 days from delivery we will charge a restocking fee of 25% of the price you paid for the item initially. This will be deducted from the value of the exchange or credit note which is issued to you. This is because  technology in the AV marketplace moves fast, and as a result the value of items decrease very quickly.

Please note we do not accept returns after 90 days, except for repairs under warranty.
