BASIC. OPERATION
CX NOISE REDUCTION SYSTEM
(Functions only during playback of video discs)
The CX noise reduction system is used to reduce noise which
may be caused during recording of the disc and thus, it im-
proves signal-to-noise ratio. When a disc marked with the CX
symbol is to be played, press the CX button on the front panel.
An indicator light will confirm that the CX decoder is opera-
tional.
While the CX decoder will significantly improve the dynamic
range of a CX disc, the disc can be played quite satisfactorily
without decoding. However, discs with no CX symbol should
not be played with the CX control on. The function can be
disabled by pressing the CX button again, making sure that
the indicator lamp goes out.
In addition, the CX system is turned off automatically when
playback stops at the end of a disc, when play is stopped
manually, or the EJECT button is pressed.

On some CX discs, a special code is recorded which automatically
turns the CX system on and off. When such a disc is played, the
player reads the code, and the CX system's on/off controls are
performed automatically, making it impossible to turn the CX
system on and off with the player's CX button. If you find during
playback that the CX system does not respond to the CX button, it
indicates that the CX switching is being performed automatically;
it is not a malfunction.

AUTOMATIC AUDIO DISCRIMINATION FOR
THE "LaserVision with Digital Sound Disc"
When playing back the LaserVision with Digital Sound Discs
on this player, the player automatically discriminates. between
Digital Sound and Analog Sound signals. When Digital Sound
signals are present, the player can automatically switch the
output of the rear panel AUDIO OUTPUT 1 terminals to
Digital Sound.
Select with the front panel VIDEO DISC AUDIO switch.
AUTO DIGITAL — With LaserVision discs recorded on-
ly in Analog Sound, the Analog Sound is output from the
"AUDIO OUTPUT 1" terminals; With LaserVision with
Digital Sound Discs (which include Digital Sound signals
and Analog Sound signals), the Digital Sound is output
from the '""AUDIO OUTPUT 1" terminals.
When Digital Sound is output, the "DIGITAL" indicator on
the player's front panel will light.
ANALOG ONLY — Even when Digital Sound signals
are recorded, the player will output only the Analog Sound.
The rear panel "AUDIO OUTPUT 2" terminals are capable of
Analog Sound signals only (Digital Sound signals cannot be out-
put here). Also, the audio for VHF output is based on Analog
Sound signals.
