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. | |

Vector Linear Shaping Circuitry (VLSC) |
|
Conventional D/A conversion methods reduce digital pulse noise at the conversion stage but can’t remove it completely. Previously only found on Onkyo’s high-end components, VLSC (Vector Linear Shaping Circuitry)employs a unique D/A conversion circuit to overcome this problem. Data is converted between sampling points and these points are joined with analogue vectors in real-time to produce a smooth output wave form. The result - a virtually noiseless, smooth analogue signal based on the digital source. |

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. | |

RI (Remote Interactive) |
|
Doing More with Your iPod - Through Onkyo's Imaginative Sight and Sound | Simply place your iPod in the DS-A1 Remote Interactive Dock connected to any Onkyo RI-compatible amplifier/receiver to experience the powerfully rich sound of Onkyo audio-video components. Control your music from your RI remote and charge your iPod while you enjoy your iPod’s digital music -and photos - through the power of Onkyo’s expansive sound, from mini systems to separate components to home theater systems. Unlike purely iPod-dedicated systems, you can fully integrate the convenience and storage capacity of your iPod with all your other Onkyo home entertainment components - and share the experience with everyone. |

A-OMF Monocoque |
| Supporting Wide Piston Motion Range | As the latest development in Onkyo Micro Fiber (OMF) for woofer diaphragms, A-OMF Monocoque forms one continuous cover from the center cap over the whole diaphragm’s surface. Like Advanced Onkyo Micro fiber (A-OMF), A-OMF Monocoque comprises three layers: an outer polyethylene naphthalate (PEN) layer, an inner aramid layer, and a flexible cotton weave layer between the two. The PEN has a twill (textile weave) that enables the fiber’s weight to be reduced by 30%. By forming one continuous layer over the surface off the diaphragm woofer, A-OMF Monocoque helps prevent breakup (occurring when the cone flexes instead of moves as a perfect piston). Essentially, the fiber is an integral part of the woofer unit, and it serves as a perfect complement to the woofer unit’s wider piston motion range. |

USB |
| Stands for "Universal Serial Bus." USB is the most common type of computer port used in today's computers. It can be used to connect keyboards, mouse, game controllers, printers, scanners, digital cameras, and removable media drives. | |
