CS-315

CD RECEIVER SYSTEM

Emitting the Sweetest, Sharpest Audio From A Smart, Compact Unit

The biggest challenge for compact audio systems is to take any music genre and reproduce a detailed, balanced audio output. If we judge
the CS-315 CD receiver system only on that basis alone, we have a winner. Anchored around Onkyo’s Wide Range Amplifier Technology (WRAT),
the CS-315 uncovers the nuance of CDs or MP3 tracks recorded to disc. An outstanding option is to team it up with Onkyo’s Remote Interactive
Dock for the iPod to bring greater audio fidelity to digital music files stored on your PC. Looking as good as it sounds, the CS-315 is enhanced
by its striking front aluminum panel and vibration-reducing build. You shouldn’t overlook the CS-315 size—this system will easily fit into
most spaces that you choose. Making a complete audio chain with the D-N7BX 2-way, bass reflex speakers, you can expect the CS-315 to
make an impression wherever you place it.

Wide Range Amplifier Technology (WRAT)for a Full, Precise Soundscape

With any compact audio system, finding the right amplifier design will help to
generate higher quality sound compared to a system built purely to meet size
specifications. Taking the cue from some of Onkyo’s renowned amplifiers and
receivers, the CS-315 incorporates WRAT to achieve three important goals in the
pursuit of higher standards in audio: 1)A wider frequency response; 2)Reduced
amplifier distortion at high volume; and 3)Better control of current and electro/
mechanical kick-back from speakers. WRAT ensures that you’ll get the best
audio playback quality possible from regular CDs, MP3s burnt to disc or your iPod.

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 CS-315 is different. It
uses discrete amplifier technology similar to that found on our bigger amplifiers
and receivers. Keeping the transistors separate at the output stage enhances
cooling, so the CS-315’s longevity is extended and interference to the audio
signal is reduced. Also, as conventional volume attenuation methods must
initially drop a signal close to the noise floor at low volumes, the signal is tainted
with noise. This noise increases when the signal is amplified. Optimum Gain
Volume Circuitry adjusts the gain so that less than half the amount of attenuation
is necessary. This signal never comes close to the noise floor thereby reducing
the risk of noise.

iPod Playback through Onkyo’s Remote Interactive (RI)System Capability

With Onkyo’s RI system capabilities, you can add other Onkyo components to
the CS-315—like a CD recorder or cassette deck—and operate them through
one single remote control. RI capability also gives you the opportunity to integrate
virtually any iPod model (including the diminutive iPod nano)with your CD
receiver system through Onkyo’s Remote Interactive Dock for the iPod. Simply
connect the dock to the CS-315, then place your iPod in the dock for a “heftier
and more detailed” sound than can be experienced with an RCA stereo cable.
To cap it off, RI capability will also give you remote operability over your iPod
for hands-off control over your digital music. The CS-315 will also accommodate
an upcoming version of the Dock.

Comprehensive Control Over All Your MP3s

With more and more music being bought online, the CS-315 is an ideal
solution for bringing greater audio fidelity to MP3s. As MP3s can be organized
in a hierarchy with folders containing files and subfolders, you can use two
modes, Navigation and All Folder, for selection and playback. In All Folder mode,
all folders appear at the same level, making it easy to select each folder. If no
file or MP3 is selected, all tracks will be played back in numerical order. With
Navigation mode, you can actually move through the folder hierarchy. The display
button on the remote also enables you to display information about the MP3
being played (including artist, title and album name).

Matching Speakers Featuring Onkyo Speaker Developments

While the CR-315 CD receiver stands out with its easy-to-fit build and striking
aluminum front panel, the accompanying D-N7BX 2-way, bass reflex speakers
round out an ergonomic balance. But these speakers have not only been
built for design considerations. They provide a range of Onkyo speaker
developments designed to match the CR-315 musically. A prime example is
A-OMF Monocoque—the latest in a series of diaphragm fibers designed to
support the piston motion range of the woofer. Compared to its predecessor,
A-OMF has a twill (cotton weave)that is 30% stronger giving it greater ability
to provide support for the woofer’s piston motion range. To deliver high
frequency sounds with finesse, the speakers include a ring-drive tweeter that
has proven to be effective in negating the effects of low-frequency interference
emanating from inside the cabinet. Finally a duct—called the Aero Acoustic
Drive—helps to cancel out interference between high and low frequency sounds.
