TRULY MUSICAL

Compact Audio System Lineup 2008

mini components_EX.qxd 08.5.21 6:59 PM Page 2

Convenient, Compact, and Truly
Musical—Audio Systems with the
Right Attributes

Convenience, simplicity, and style: three essential elements of a good compact audio system. Under the Onkyo name, it gets a lot

more ambitious, with audiophile-quality sound, innovative technologies, and undeniable performance. At the hear t of each Onkyo

system is an award-winning CD receiver design that produces soul-inspiring music. It’s a high-end approach to creating an

integrated, space-conscious audio solution.A solution that looks and sounds great in living rooms, bedrooms, kitchens, offices—

anywhere you wish.

Proprietary Onkyo Speaker Developments for Sublime Audio

The accompanying speakers are worthy of praise and feature some remarkable speaker

developments designed to match the respective receivers musically. The woofer cones follow our

A-OMF Monocoque design, incorporating a multi-layered diaphragm fiber that has been shown to

improve mid-range clarity for a vivid, natural sound.Also, to deliver high-frequency sounds with

finesse, each speaker’s ring-drive tweeter restricts low-frequency interference from inside the

speaker. And a precision designed duct—the Aero Acoustic Drive—further

mitigates interference between high and low frequencies.

Front Panel USB Interface for Mass Storage Devices (Such as
Flash Drives and Portable Audio Players)

More and more of our music is being purchased and stored on PCs. Integrating USB flash drives

and portable audio players with Onkyo’s compact audio systems enables you to get the best out

of your digital music files (e.g. MP3 and WMA).A front-panel port lets you connect storage devices

that support the USB Mass Storage Class Standard and relay digital files from your computer or

MP3 player for more expansive music playback.

Sturdily Built to Suppress Even the Smallest Vibrations

Every element inside these compact receivers—from the capacitor s to the circuit substrates—has

the potential to produce vibration noise. That’s why so much thought has been put into the

construction of every CD receiver in the range—from the robust, rigid chassis and aluminum front

panel to the drive mechanism. We can maximize the potential of the overall system’s sound quality

by focusing on how even the smallest detail contributes to noise.

High-Quality Binding Posts for Secure Cable Connections

Poor binding posts not only degrade the sound, they also break easily.You will find quality banana-

plug-compatible posts on all these compact audio systems.The transparent binding posts on the

CR-725 and CR-525 are gold-plated to further protect the signal and to prevent tarnishing.

The Option of iPod Playback Through RI Dock for the iPod

*

Onkyo’s RI (Remote Interactive) function enables Onkyo system owners to integrate compatible

components for operation via a single remote control. It also enables a dedicated iPod dock to be

connected to any of these compact audio systems. Simply place your iPod in the dock and use the

system’s remote control to navigate and play back MP3 files.The RI Dock offers what

independent experts have called a “heftier and more detailed” sound compared

to other direct connections.

Amplification Design Built Around the Onkyo Sound

Due to obvious size limitations, compact audio systems present various challenges for amplification design,

particular ly when audio quality is the key consideration. Onkyo’s solution is a time-honored, tried-and-tested

design concept: Wide Range Amplifier Technology (WRAT). Applying WRAT as the backbone of our compact

audio systems enables three distinct advantages: 1) A wider frequency response compared to other compact

audio systems; 2) Reduced amplifier distortion at high volume; and 3) Better control of current and

electrical/mechanical kick-back from speakers. It’s a formula for producing music

with exceptional tonal balance, clarity, and vitality.

Vector Linear (VL) Digital Modulation Circuitry for Accurate
Conversion

VL Digital modulation circuitry enables effective digital-to-analog conversion in Onkyo’s switching amplifiers and

select compact audio systems.To prevent spike noise from introducing inversion-timing errors during the

conversion process,VL Digital converts the analog audio signal with a high degree of accuracy.When an analog

input is received, the vector generator outputs a current propor tional to the size of the analog input. This

current is sent to an integrator, where it is charged. When the charge reaches a specified value, the trigger

operates and inverts the output pulse. Spike noise is eliminated as negative

and positive charges of the waveform cancel each other out.

Optimum Gain Volume Circuitry for Signal Preservation

With all Onkyo components, preserving the integrity of the audio signal is a fundamental concern. And this range

of compact audio systems is no different.The included Optimum Gain Volume Circuitry prevents noise from

adversely affecting the audio signal when it drops close to the noise floor, by making adjustments to the gain that

reduce attenuation by 50%.This ensures that even the slightest instance of noise is prevented from degrading

audio when volume is increased.

Vector Linear Shaping Circuitry (VLSC) to Maintain Clean Audio Signals

Experts agree that isolating the playback and amplification stages in any compact audio system will vastly

improve performance. Systems that incorporate VLSC at the playback stage can produce a noise-free analog

signal from digital music sources.This technology is effective in removing pulse noise during the digital-to-analog

conversion process, thereby ensuring you get the best possible audio from

CDs and compressed formats such as MP3.

Wolfson®Microelectronics Stereo Digital-to-Analog
Converters (DACs)

These compact audio systems support an efficient integrated amplification design with precise

processing devices. As a prime example, in both the CR-725 and CR-525 you will find Wolfson

stereo digital-to-analog converters (DACs) with high bit-rates and

sampling rates.The expertise of Wolfson Microelectronics makes

a significant contribution to audio quality.
