Disc Compatibility: The Onkyo C-7000R single-disc CD player will play
Audio CDs and CD-R/CD-RW discs (12cm/8cm). It will also supports playback of MP3
(32-320kbps; 32/44.1/48 kHz) and WMA (32-192kbps; 32/44.1/48kHz) files recorded onto CD-R/RW discs
in ISO9660 Level 2. The CD player can recognize up to 99 folders and up to 499
files per MP3/WMA disc.
Silent Disc Mechanism w/ Die Cast Tray: Affixed to four supports made
of rigid machined brass, the C-7000R's CD drive provides excellent resistance to
internal vibrations. Furthermore, the disc tray is precision engineered from
high-rigidity, die-cast aluminum. Thanks to these advanced design features, the
disc mechanism offers smooth and silent operation.
High-Rigidity, Anti-Resonant Chassis: The C-7000R features
separate aluminum panels for the top, sides, and front to reduce unwanted
vibrations caused by internal resonance. Compared to a one-piece chassis design,
this construction method offers greater rigidity and improved noise reduction
Side-Mounted Circuit Board Construction: Rather than being
directly connected to the chassis base, the circuit boards inside the C-7000R
are cushioned by internal struts and affixed to the front, side, and rear
panels. This method of construction prevents vibrations from the chassis from
adversely affecting the circuit boards.
Separate Digital/Analog Circuitry and Transformers: To prevent
unwanted interference, the C-7000R employs physically separate circuitry for
digital and analog processing. The player also features separate transformers
for digital and analog circuitry.
Massive Toroidal Transformer: The C-7000R incorporates a massive
toroidal transformer for the analog circuitry that reduces magnetic flux
leakage, improves efficiency, and keeps the power supply stable. For the digital
circuitry, meanwhile, it employs a high-quality EI transformer.
Dual TI Burr-Brown 24-bit-/192kHz DACs (PCM1792): High-quality TI
Burr-Brown DACs work to optimize analog audio performance on the C-7000R. The
player incorporates two of TI Burr-Brown's flagship 24-bit/192kHz PCM1792 DACs.
Although these DACs can process two-channel audio on a single chip, Onkyo
employs separate chips for each stereo channel, to ensure the most accurate
Thermally Regulated Super-Precision Clock: The C-7000R boasts an
extremely precise clocking mechanism that controls and coordinates the timing of
all digital signal processes, like how a conductor directs and coordinates the
individual instruments of an orchestra. The C-7000R uses a state-of-the-art
crystal oscillator that achieves a frequency deviation of +/-1.5 ppm at room
temperature (much lower than with a conventional oscillator). Even in
surrounding temperatures of -30°C or +80°C the frequency remains stable, with
only+/-0.5 ppm of additional frequency deviation.
PLL (Phase Locked Loop) Ultra-Low Jitter Technology: Jitter is an
unwanted side-effect of the digital-to-analog conversion process caused by
fluctuations in the time domain of a digital signal. PLL ultra-low jitter
technology reduces jitter by comparing the input and output phases of the
digital signal and creating an accurate clock waveform. This enhances the
precision of digital signal processing and noticeably improves perceived audio
VLSC (Vector Linear Shaping Circuitry): In conventional digital-to-analog conversion methods, it's impossible to completely remove noise. This noise taints the analog signal and ultimately degrades the sound emitted from your speakers. With Onkyo's VLSC, though, data is continuously sampled between two discrete points
(via a signal comparison generator) and the difference is joined with analog vectors in real time to produce a smooth output waveform. The VLSC digital-to-analog conversion method results in an accurate, virtually pulse noise-free audio signal that faithfully reproduces the acoustic detail and subtle nuances of all your audio sources, and breathes life into digital media.
DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry): Since
the advent of digital audio, signal-to-noise ratios have improved dramatically.
However, the S/N ratio reflects static noise only, and takes no account of
another type of noise that occurs as the byproduct of sound reproduction;
dynamic noise. To reduce this type of noise, Onkyo has developed DIDRC
technology for use in their hi-fi components. Despite being beyond the normal
range of human hearing, frequencies above 100 kHz are susceptible to clock pulse
and other forms of distortion from digital devices. Such distortion in the
super-high-frequency range can generate "beat interference", which in turn
affects the character of the original sound. By improving linearity and reducing
distortion in the super-high-frequency range, Onkyo's DIDRC technology
effectively reduces perceptible noise and delivers clearer audio.
Front-Panel LCD: The Onkyo C-7000R features a front-panel LCD which can
display the following disc information - Time Elapsed/Remaining, File/Folder
Name, Song Title, Artist Name, Album Name, and Sampling-/Bit-rate. You can
adjust the brightness of the display from Normal, Dim, Dimmer.
Remote Control: The Onkyo C-7000R single-disc CD player includes an IR
remote control for wireless operation of the player and basic playback functions
of a connected USB memory device or Apple iPod/iPhone. There are also basic playback controls
located on the player's front-panel.
Direct Track Access: The numeric keypad (0-9, >10) of the remote
control can be used to directly access a track or file on a disc.
File/Folder Mode: During MP3/WMA playback, you can choose to search
for files (songs) within a folder or on an entire disc.
25-Track Memory Playback: You can create a playlist of up to 25
tracks/files per disc.
Random Playback: In Random playback mode, all of the files on a disc
are played back in random order.
Repeat Playback: In Repeat playback mode, you can playback an entire
disc repeatedly, play one track/file repeatedly, combine it with memory playback
to play a playlist repeatedly, or combine it with random playback to play all
tracks on a disc in random order repeatedly.
Audio Filter: You can select what type of digital filter is
applied to the PCM data prior to D/A conversion for analog input output; this
will switch the response inside and outside the audible bandwidth. You can
choose from Sharp (allows the band property up to 20kHz to be output almost
flat) or Slow (allows for more precise sound image localization of each musical
Phase Switch: This setting configures the phase of the player's analog
output. Use the Phase switch to obtain optimum sound quality from the player to
your amp and speakers. You can select from Normal or Reverse.
Auto Standby Function: If the CD player is left stopped for
approximately 30 minutes, the power will automatically turn off, placing the
unit in Standby mode. If playback is simply pause, the power will remain on even
after 30 minutes have elapsed.
Analog Audio Output: The Onkyo C-7000R single-disc CD player is fitted
with a set of stereo RCA analog audio outputs to connect to your home receiver.
Optical/Coaxial Digital Outputs: The Onkyo C-7000R features two digital audio
outputs; one optical (toslink) and one coaxial (RCA). The player's digital
outputs support 16-bit/44.1kHz PCM (2ch).
AES/EBU Balanced Digital Output: The Amphenol AES/EBU digital
output is a professional digital audio interface which provides resistance to signal degradation and noise.
The player's AES/EBU output supports 16-bit/44.1kHz PCM (2ch).
1/4" Headphone Jack: The Onkyo CD Player features its own
built-in headphone amp with a front-panel 1/4" headphone jack and independent
volume control. Connecting a set of headphones to the front-panel 1/4" jack does
not mute the player's audio outputs (you will need to turn down the volume
on your receiver).
