Onkyo’s proven Wide Range Amplifier Technology concept—along with upgraded Three-Stage Inverted Darlington Circuitry & VLSC™ noise-canceling technology—lies at the very heart of Onkyo’s premium hi-fi separates range. The good news is that this same technology is now powering selected compact models such as this one. Combined with the symmetrical layout of the left & right channels & an audiophile-grade 192 k Hz/24-bit DAC, distortion is all but eliminated & your music is brought to life. Hear your cherished albums played back with the sort of depth & clarity you might expect from a high-end system. With the CS-555DAB, you can spin CDs or explore the world of digital radio, plug in an iPod or flash drive to the USB (Universal Serial Bus) port, or enjoy the i Tunes library on your PC via 96 k Hz/24-bit digital inputs. Our latest bookshelf loudspeakers feature N-OMF cotton & aramid laminate cones with center-mounted bullet equalizers to minimize vibration. These speakers smoothly handle phase-matched & boosted bass without obscuring the m id-range frequencies. Robust construction & a quality finish reflect the premium audio technology inside, all in system everybody can afford Find Your New Favorite Station Digital radio is one of the best sources of free, high qualityhome entertainment. Whether you like music, talkback, comedy, or current affairs, the DAB/DAB+ functionincluded on this mini system opens up a diverse world ofprogramming to browse & enjoy. Unlike the old dayswhere you’d be afraid to touch the dial in case you lostyour original station, changing channels is now a matter ofpushing a button & selecting from the 40-preset memory. Furthermore, digital radio delivers sound quality that’s asgood—and in most cases, better—than traditional FMbroadcasts, while being less susceptible to environmentalinterference.WRAT (Wide Range Amplifier Technology) for Naturally Vivid Sound Onkyo developed the WRAT suite of technologies toimprove the clarity & character of amplified audio. Thetechnologies work to reduce noise across the frequencyrange, guaranteeing a clear & natural sound. It achievesthis by employing a low negative feedback amplifierdesign, preserving the energy & life contained within therecording; using closed ground-loops to cancel unwantednoise from individual circuits; & by enabling high currentflows to cancel reflex energy from the speakers. Top Quality Amplifier for Pure Audio Clarity While some hi-fi makers take a shortcut to amplified audiowith the use of cheap all-in-one IC chips, the resultingsound too often distorts once you turn the volume up. Instead, Onkyo uses the same discrete Three-Stage Inverted Darlington amplification circuitry found on its flagship A/ Vand hi-fi components in selected compact models such asthe CS-555DAB. The result is full & pure sound from anaffordable, space-saving audio system. Low Noise Technology for Accurate Sound Short pathways from power supply to amplifying circuitreduce the chance of electrical interference, while a topquality 192 k Hz/24-bit DAC & three-stage amplificationprocess maintain the integrity of audio signals. A symmetricaland uniform layout minimizes the chance of interferencebetween left & right channels. In fact, our lab testing showsthe CS-555DAB to reproduce audio that’s four times clearerthan conventional models, while channel interference hasbeen reduced to almost zero for superb stereo separation. Phase-Matching Bass Boost System From the warm low notes produced by a cello to the deepfrequencies of electronic music, a good compact audiosystem should be able to deliver plenty of bass resonance. While traditional enhancement systems effectively boostlow-frequency sound, they are often prone to the effects ofphase shifting, which can overwhelm mid-range frequenciesand muddy the sound. Our Phase-Matching Bass Boosttechnology effectively preserves mid-range clarity—allowingvocals & strings to shine—while maintaining a smooth, powerful bass response at all volume levels.
