DTS 5.1 Neo:6 |
| Bringing DTS 5.1 Neo:6 Decoding for Matrix Surround Sound |
DTS 5.1 Neo:6 is an advanced matrix decoder that takes any two-channel source (including VHS tapes, television broadcasts, CDs and DVDs) and expands it into five or six channels. It also provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. Previously, DTS Neo:6 was only available as part of DTS-ES (6.1 and above systems), and no DTS system existed for 5.1-channel systems. DTS have introduced DTS Neo:6 5.1, which like Dolby Digital’s Pro Logic II, brings you a more revealing sound from ordinary stereo and a more expansive home cinema experience. |

Dolby Digital & Pro Logic II |
| Dolby Digital, with 5.1 (6) discrete channels, is the designated multichannel format for DVDVideo, HDTV, and select satellite TV broadcasts. Dolby Pro Logic II, the newest format, creates a quasi-5.1-channel experience, with stereo, full-bandwidth surround channels (as opposed to plain Dolby Pro Logic’s single, mono surround channel), from Dolby Surround film soundtracks and stereo music sources. | |

192 kHz/24-Bit Audio DACs |
|
Performing at a full 192 kHz/24-bit level of resolution, these state-of-the-art digital-to-analog converters deliver audio performance that is second to none. They boast a higher dynamic range than standard D/A converters, and are virtually resistant to clock jitter -- which means you’ll enjoy the best performance possible from DVD-Audio discs and Super Audio CDs and cleaner sound from your regular DVDs and CDs. |

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. |

CinemaFILTER™ |
| The tonal balance of a film soundtrack can be edgy and bright when played back over audio equipment in your home - this is because film soundtracks are designed to be played back in large theaters, using commercial equipment. Onkyo has developed its own solution that restores the correct tonal balance of a movie soundtrack in the smaller environs of your home theater. | |

OptiResponse Equalizer |
| RI (Remote Interactive) Remote Control with OptiResponse Equalizer Function |
You can now fully optimize audio performance with the remote controller’s OR-EQ (OptiResponse Equalizer) function. At the press of the OR-EQ button, you can boost the low-and high-end frequencies of movies and music without having to increase volume. |
|
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. | |
