| Chunky Onkyo could KO rival | |
| "Whether playing CDs or listening to the tuner, the Onkyo introduces a metallic chruchy element to the sound. Mind you, products like this tend to see service in a small room -such as a bedroom or kitchen- where thumping volume levels aren't often required. The Onkyo fits the bill decoratively, and doesn't disgrace itself at more realistic levels of volume..." Verdict: 5 from 5 Stars | |

MP3 |
| MP3s are digital audio files that have been compressed, yet which still maintain the sound quality of the original. Before there were MP3s, digital audio files took hours to download. But on a 56K modem, most MP3s can download in just a few minutes. MP3s are widely recognized as the most popular format for storing and listening to music on the World Wide Web. Listening to MP3s is easy. You just need to download a player, a software application that lets you hear music on your computer. MP3 is short for MPEG Audio Layer 3. MPEG refers to the Moving Pictures Experts Group, an organization that sets international standards for digital formats for audio and video. The file-shrinking technology itself was developed by the Fraunhofer Institute in Germany. | |

Benefit 1: Uncommonly Low Negative-Feedback Design—so you’ll enjoy cleaner sound on programme peaks | Although NFB (negative feedback) is the most cost-effective way to reduce noise at lower frequencies, there’s a sonic price to pay: larger amounts of NFB severely inhibit an amplifier’s transient response—the ability to respond to large signal gains (e.g. explosions and musical finales)—and actually distort sound at high frequencies. That’s why our engineers use a low negative-feedback design, with audiophile-grade, close-tolerance components at critical points in the signal path, to achieve a frequency response out to 100 kHz. That means you can fully enjoy the sonic benefits from such high-resolution formats as DVD-Audio and Super Audio CD as well as your regular CDs and DVDs. |

Benefit 2: Closed Ground-Loop Circuits—so you’ll enjoy greater maximum volume without distortion | If an amplifier’s ground potential (voltage) fluctuates during playback of movie soundtracks or musical performances, you wind up with unpleasant noise. In an open-loop circuit design, all circuits are connected to the power supply via one loop. If all circuits share the same loop (like on many amplifiers), the noise multiplies exponentially. Onkyo’s sophisticated closed-circuit design allows each circuit to go and return directly to the power supply. This cancels any individual circuit noise, and keeps the ground potential free of distortion. |

Benefit 3: High Instantaneous-Current Capability—so you’ll enjoy film soundtracks with greater impact | Audio signals are very complex. After the amplifier outputs such signals to a speaker, the speaker itself accumulates energy. When the speaker reflexes, it sends energy back to the amplifier. The amplifier must immediately be able to supply a large amount of high current to cancel the speaker’s reflex energy, and instantaneously send out the next signal. The same high current is also necessary to handle speaker impedance fluctuations, which on occasion force an amplifier to provide four to six times its usual current load. The instantaneous current capability of even Onkyo’s least expensive WRAT receivers is far better than that of most conventional units. This is because competing designs commonly have less than half the current capability. The result? The high-current capability incorporated into all Onkyo receivers means your receiver can deliver movie soundtracks with theatre-like dynamics and clarity—so you’ll get the same exciting sonic slam that you experienced in the cinema. |

DAB (Digital Audio Broadcasting) |
| Digital Audio Broadcasting (DAB) optimises receiver sensitivity to ensure interference-free and CD-quality radio programming. Unlike analogue radio, DAB also transmits text, visuals, data and video to completely revolutionise radio media! | |
|
RDS (Radio Data System) |
| Since 1987, this system has simplified the tuning of programming of an increasing number of radio frequencies. Incorporated into radio receivers, the system selects programs and displays them on the receiver’s alpha-numerical display. Also, a microprocessor enables the receiver to determine the transmitter frequency that gives the best quality reception. | |

CD Audio |
| Based upon Red Book specifications, CD-Digital Audio is able to hold audio data at a sampling rate of 44.1 KHz and a sample size of 16 bits, to produce high quality stereo sound. | |

ONKYO'S Micro Fiber (OMF), A-OMF & A-OMF Monocoque |
|
OMF, made from a pure cotton weave to absorb vibrations, was first developed to create a thick yet rigid diaphragm that enables an extremely fast, accurate response. The next stage saw the advent of A-OMF, which incorporates a PEN (polyethylene naphthalate) layer with a flexible cotton weave that makes speaker cones even stronger and more resistant to heat. We then added an aramid layer to create NEW A-OMF. The evolution has been taken a step further with A-OMF Monocoque--essentially sharing the same material composition as A-OMF but forming a single, continuous cover over the cone. All diaphragm types achieve improved midrange clarity and imaging for an astonishingly vivid, natural sound. |
