Features

0 Opto-Coupling'

Onkyo's original Opto-Coupling technique electrically separates the digital and analog circuit blocks for a playback sound free of the

harshness sometimes associated with CD players.

0 Two~Times" oversampling and Digital Filtering

The two-times oversampling/digital filtering procedure increase the sampling frequency from the standard 44.1 kHz to 88.2kHz. As a
result, ultrasonic noise begins at a frequency of 68.2kHz-well above the upper limit of the audio band (20kHz)- so a steep analog filter
is not necessary. This method preserves high -frequency phase accuracy, resulting in much more natural treble sound reproduction.

Eight-Digit Fluorescent Display
The mum-function display indicates the current track number, the next track number, and the memory channel number, as well as the
consumed/remaining time in minutes and seconds. This display capability facilitates easy song selection and tape dubbing operations.

Special Vibration Damping
To prevent vibrationerelated tracking errors, Onkyo "floats the entire drive assembly on four supports consisting of spring coils damped
With vibration-absorbent rubber.

Three-Beam Laser Pickup
In threevbeam systems. the main beam searches for the presence of either a shiny surface, or a pit. Two auxiliary beams straddle either
side of the disc track, searching for the presence of adjacent tracks. Such pickups are less liable to be fooled" by disc defects like scratches
which can cause mistracking.

Output CMN Filter
This special nOise filter consisting of a bi-filar wound ferrite ring core is incorporated into the output (analog) circuitry to make absolutely
certain that no digital pulse interference of a type known as CMN (common mode noise) be allowed to degrade the DX~230s output

signal.

0 10-key wireless remote control included

The DX»230 includes a ten-key remote control capable of covering the play. stop, pause, program memory and clear memory functions.

You'll only have to get up to put the CD into the player.
