length of cable used, adjust the SC control with the CHROMA

NOISE REDUCER
The
Noise
Reducer can be switched ON
or OFF
using NR
ON/OFF switch @
inside the front panel.
The Y-NR has three positions;
QO: OFF
1: High-frequency NR for edge noise reduction
2: High-frequency
NR + Low-frequency NR for reduction
of edge noise and plane area nose
Mode 2 provides more effective noise reduction than Mode 1;
however,
Mode
2 reduces resolution somewhat; so Mode
1 is
preferable.
The C-NR has 16 positions;
0: OFF
1,2, 3, % 9, 6, 7, 8, 9, At10), B(1T}, C(12), D(14);,.E( 14)
and F(15).
With
positions
1 to
F, the
limiter
width
is varied
in order
to provide the most suitable effect. Usually, use position 7.

More effective NR
More image lag
Since noise reduction is done using field difference in principle
it results
in
image
lag.
For this reason,
with
a picture with
ing plenty of motion, use positions
1 to 5, with which
image
lag is virtually unnoticeable (but the NR effect will be less). In
the case of a picture having less motion
or a still picture, use
positions with
greater
noise
reduction
(but image lag will be
greater as well).
