CS-515UK

CD Receiver System



Compact in Size Yet Detailed, Balanced and Spacious in Sound

Building on the success of its immediate predecessor, the CS-515UK CD receiver system embodies an approach to sound—detailed, balanced and spacious—that belies its size. The CD receiver itself exudes an air of solidity that is further accentuated by a concave, aluminum front panel. Also, not visible to the eye, the receiver’s chassis has been constructed with a flatter underside that has proven to be effective in removing extraneous vibrations. On the inside, audio quality is promoted with the inclusion of a Wolfson® 192 kHz/24-bit DAC. The CS-515UK’s relative power enlivens CD playback, provides inspiring Digital Audio Broadcasting (DAB), and gives your MP3 files an edge they’ve been missing. Also, combining the CS-515UK with Onkyo’s iPod Dock and wireless USB audio transport (UWL-1) bring a whole new dimension to your computer-based music sources. It’s improvement in increments for the receiver, but a brand new direction for the D-N9BX 2-way, bass reflex speakers that round out this system, which make it a fine investment for the home.

ONKYO micro´s a UK-tuned treat 
(...) Surprisingly good speakers
Listen to the complete package and you´re in for a musical treat.Outcast, Beethoven, whatever - the CS-515DAB combo delivers it with all skill, and no small degree of finesse. Good timing is rare or any micro, but this system has it pegged.The system punches forcefully, too, while sound quality from the tuner, whether DAB, FM or MW, is more-than-adequate. The CS-515DAB is a terrific product. Don´t buy any other micro without trying this one out first.

FOR: A musical and entertaining performer; good speakers
VERDICT: This ONKYO is that rare thing: a truly musical micro system

A truly musical micro system
(...) Small in size, but not in performance, the CS-515UK is a blinder (...) "The ONKYO system sounds great - and that´s not just by micro system standards." Simon Lucas - First Tests Editor (...) Good timing is rare on any micro, but not here - dance music thunders along, while reggea has snap. If you´re in the market for a new micro, put this on your short list. VERDICT: This ONKYO is a rare thing: a truly musical micro system. The overall performance is fantastic, right down to its small optional speakers.
 


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.
 
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.
 
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.
 
WRAT2
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.
