CS-725 CD Receiver System
Vector Linear (VL) Digital Modulation Circuitry for Accurate
Conversion
The CR-725 CD receiver’s switching amplifier design uses VL Digital modulation
circuitry for effective digital-to-analog conversion.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 proportional 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.
Heavy-Duty Power Supply to Support Highly Efficient
Amplification
With a focus on providing a highly efficient and stable power supply, the CR-725
CD receiver includes a heavy-duty, customized power transformer designed to
fit into the receiver’s limited space.The power supply is also equipped with a
high-quality capacitor (operating at 4700 µF) to store and regulate power for
stable, responsive digital amplification.
Thick, Low-Impedance Bus Plate to Support Current
Capability
The CR-725 CD receiver incorporates a thick, low-impedance copper bus plate
in the circuitry to ensure a flawless electrical energy path. Furthermore, as the
ground potential is capable of imparting noise into the audio signal, the CR-725
CD receiver is constructed so that the ground points of each circuit do not
affect one another.The bus plate has proven to be effective in contributing to
accurate audio reproduction.
Vector Linear Shaping Circuitry (VLSC) and Optimum Gain
Volume Circuitry to Maintain Clean Audio Signals
The CR-725 CD receiver uses VLSC to 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 maintaining the purity of the
signal. Employed in Onkyo’s A/V receivers and playback components,VLSC
ensures you get the best possible audio from CDs and compressed formats
such as MP3.
Optimum Gain Volume Circuitry is also used to prevent noise from adversely
affecting the audio signal.This circuitry makes adjustments to the gain, thereby
reducing attenuation by 50%, so the signal never comes close to the noise floor.
By contrast, in conventional volume attenuation methods (where no gain
adjustment is made), the signal drops close to the noise floor at low volumes.
This taints the signal with noise that is noticeable when the signal is amplified.
Gloss-Finished Speakers with Select Performance-Enhancing
Features
The accompanying D-N10BX two-way, bass-reflex speakers are housed in gloss-
finished MDF cabinets that will impress in any environment. Musically, they
incorporate a range of Onkyo speaker developments designed to match the
CR-725 CD receiver. For example, the woofer cones follow Onkyo’s A-OMF
Monocoque design and incorporate a diaphragm fiber that supports the
speakers’ piston motion range.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—
called the Aero Acoustic Drive—is included to mitigate interference between
high and low frequencies.
The Option of iPod Playback Through RI (Remote Interactive)
Dock for the iPod*
The RI system enables Onkyo owners to integrate compatible
components for operation via a single remote control. It also enables
you to integrate the iPod with the CS-725 through Onkyo’s optional
RI Dock for the iPod. Simply connect the dock to the CD receiver,
then place your iPod in the dock for control with the CR-725 CD
receiver’s remote control.The RI Dock has been hailed by
independent experts as offering a “heftier and more detailed” sound than can
be experienced with an RCA stereo cable.

Much More Than a Sum of Parts—Exclusive, Customized and Smart
This compact audio system features a switching design for efficient audio playback. Based on the Onkyo systems that dominate in the
Japanese domestic market, the CS-725 is packed with proprietary technologies, customized and selected parts, and intelligent design
considerations.The CS-725 uses both Vector Linear (VL) Digital modulation circuitry and Vector Linear Shaping Circuitry (VLSC) to
maintain the purity of audio signals.You’ll also find a weighty, customized power supply; a robust chassis supported by a steel top cover
and aluminum front/side panels; and quality gold-plated input and output terminals.The accompanying gloss-finished speakers sound as
good as they look, and serve to round out one of Onkyo’s finest compact audio systems to date.
