CD Receiver System
Built Around Proven Amplification Design, Solid Build Quality and
Impressive Musicality
Mini audio systems are all about improving your lifestyle. Beyond merely saving space, though, the right mini system adds functionality
and style in an integrated package.The CS-325 CD receiver system takes things a step further, thanks to its exceptional ability to
reproduce audio. Here, Onkyo has applied the same approach used in its acclaimed two-channel audio line-up.The end result is a
system best described with one word—musical.The system’s multi-format-capable receiver sports a robust chassis designed to
suppress vibrations. Meanwhile, the accompanying speakers feature a gloss finish on the front, as well as proprietary Onkyo speaker
developments designed to deliver audio signals with punch, clarity and emotion.
Amplification Design Built Around the Onkyo Sound
The Option of iPod Playback Through RI Dock for the iPod*
Due to their obvious size limitations, mini audio systems present various
challenges to amplification design.The concept behind the CS-325 was to
design a compact system with audio quality as the key consideration.Therefore,
Onkyo’s engineers incorporated the same technology used in our renowned
full-sized amplifiers and receivers: Wide Range Amplifier Technology. WRAT gives
the CS-325 three distinct advantages: 1) A wider frequency response compared
to similar mini audio systems; 2) Reduced amplifier distortion at high volume;
and 3) Better control of current and electrical/mechanical kick-back from
speakers.This enables the CS-325 to deliver audio of surprisingly high quality
from such a compact component.
Onkyo’s Remote Interactive (RI) function enables Onkyo component
owners to integrate compatible components for operation via a
single remote control. It also enables you to integrate the iPod with
the CS-325 through Onkyo’s optional RI Dock. Simply connect the
dock to the CS-325’s receiver, then place your iPod in the dock
for control via the CS-325’s remote.The RI Dock offers a “heftier
and more detailed” sound than can be experienced with an RCA stereo cable.
Exclusive Onkyo Circuitry to Maintain Clean Audio Signals
Lower-quality mini audio systems usually employ just one circuit at the output
stage. With multiple transistors crammed onto a single circuit, excess heat is
generated and the audio signal is compromised.The CR-325 CD receiver is
different. It uses discrete amplifier technology similar to that found on Onkyo’s
full-sized amplifiers and receivers. Keeping the transistors separate at the output
stage enhances cooling, so the CR-325’s longevity is extended and interference
to the audio signal is reduced.
Conventional volume attenuation methods involve initially dropping a signal
close to the noise floor at low volumes.This taints the signal with noise, which
increases when the signal is amplified. By contrast, Optimum Gain Volume
Circuitry adjusts the gain so that less than half the usual amount of attenuation
is necessary.The signal never comes close to the noise floor, and the risk of
noise is therefore reduced.

Gloss-Finished Speakers with Proprietary Onkyo Features
The accompanying D-325 two-way, bass-reflex speakers have a gloss finish on
the front that will impress in any environment. Musically, they incorporate a
range of Onkyo speaker developments designed to match the CR-325 CD
receiver. For example, the woofer cones are made from Onkyo’s A-OMF
Monocoque—a diaphragm fiber designed to support the range of piston
motion. Also, to deliver high-frequency sounds with finesse, the speakers include
a ring-drive tweeter that contributes to the restraint of low-frequency
interference from inside the speaker. Finally, a duct—the Aero Acoustic Drive—
is included to further mitigate interference between high and low frequencies.
Simple Yet Comprehensive Control over All Your MP3s
With more and more music being bought online, the CS-325 is an ideal
solution for bringing greater audio fidelity to MP3s. As MP3 files can be
organized hierarchically in folders, you can use either of two modes—
Navigation or All Folder—for selection and playback. In All Folder mode, all
folders appear at the same level, making it easy to select one. If no specific file
or MP3 is selected, all tracks will be played back in numerical order. On the
other hand, Navigation mode lets you move through the folder hierarchy.The
display button on the remote also enables you to see information about the
MP3 being played, including the artist’s name and the song and album titles.
