Discription
of
Functions
The
automatic
HiFi
record
player
CS
650
RC
is
a
remote
con-
trollable
turntable
with
front
controls.
The
power
is
supplied
by
means
of
a
mains
transformer
and
a
power
supply
board.
The
turntable
is
switched
to
"stand-by"
mode
by
operating
the
"power"
switch.
D
900
and
C
9402
on
the
power
supply
board
provide
a
DC
voltage
of
30
V
for
the
infrared
receiver.
The
21
V
DC
voltage
isgenerated
by
means
of
thediodes
D
9401-
9402
and
C
9403.
The
direct
drive
motor,
the
stand-by
LED,
the
selenoids,
the
stroboscope
LEDs
and
IC
9400
are
supplied
with
this
voltage.
The
IC
operating
voltage
of
5
V
is
stabilized
by
means
of
IC
9400.
In
addition
to
the
voltage
supplies,
the
sole-
noid
driver
transistors
T
9400—T
9405
are
accommodated
on
the
power
supply
board.
The
microcomputer
board
is
linked
to
the
power
supply
board
by
means
of
a
connector
strip.
Operation
of
the
touch
buttons
for
the
functions
"start,
I
ift
and
stop"
acts
upon
the
inputs
of
the
microprocessor.
Via
resistors,
/hese
three
inputs
become
active
"H".
The
corresponding
input
is
set
to
"L"
by
operating
a
button.
The
microprocessor
sets
the
corresponding
output
to
"H".
The
transistors
T
9400,
9401
and
9402
are
blocked
via
the
in-
verter,
the
transistor
T
9403,
9404
or
9405
becomes
conductive
and
the
command
is
executed
by
means
of
the
solenoid.
The
infrared
signal
is
fed
in
via
the
capacitor
C
9305.
The
operating
voltage
for
the
infrared
receiver
is
stabilized
to
18
V
with
the
Zener
diode
D
9302.
The
active
duration
of
the
commands
start,
lift
and
stop
is
fixed
in
the
microprocessor
and
amounts
to
approximately
1.3
sec.
During
this
time,
the
"muting"
output
of
the
processor
receives
active
"L";
via
the
inverter,
signal
"H"
reaches
the
base
of
T
9151
which
activates
the
relay
and
thus
shorts
the
two
audio
channels.
The
stand-by
LED
is
activated
via
the
resistor
R
9408.
If
the
motor
is
switched
on,

can

When
the
platter

is
rotating
at
exactly
33
1/3
or
45
rpm
the
lines
of
the
stroboscope
appear
to
stand
still.
If
the
lines
move
i,n
the
direction
of
rotation
of
the
platter,
the
platter
speed
is
too
high.
If
the
lines
move
backwards,
the
platter
is
rotating
more
slowly
than
the
nominal
speed.
Adjustment
of

and

can
make
with

Strobe

are
provided
on
the

of
the

line
frequencies.
To
replace
LED
154
remove
machine

and
remove

lt
can
happen
that
the
stroboscope
lines
appear
to
move
slightly
although
the
exact
speed
setting
with
stroboscope
stationary
has
not
been
altered.
This
apparent
contradiction
is
explained
by
the
fact
that
the
electronic
central
drive
motor
operates
fully
inde-
pendently
of
line
frequency
whilst
the
only
relatively
accurate
line
frequency
of
the
AC
current
supply
is
used
for
speed
measurement
with
the
light
stroboscope.

according
to
the
information
of
the

companies
brief
frequency
fluctuations
up
to
1
%
are
possible
-
only
effect
the
stroboscope
indication
and
can
cause
the
lines
to
"wander"
although
the
platter
speed
is
as
constant
and
absolutely
accurate
as
before.
Pitch
Control
Each
of
the
two
standard
speeds
33
1/3
and
45

(78

can
be
varied
by
about
10%.
The
variablespeed
control
157/R
19
located
in
the
voltage
divider
is
adjusted
by
turning
the
pitch
control
knob
10.
By
this
the
differential
amplifier
is
altered
and
the
motor
speed
accordingly.

Tonearm
and
Tonearm
Suspension
The
feat
her-light,
extremely
torsion
resistant
all-metal
tonearm
is
suspended
in
a
gimbal.
Suspension
is
by
means
of
4
hardened
and
precision
polished
steel
points
which
rest
in
precision
ball
bearings.
Tonearm
bearing
friction
is
thus
reduced
to
a
minimum.

Bearing

(0.015

as
related
to
stylus
point.
As
a
result,
it
ensures
most
favourable
pick
-up
conditions.
Before
adjusting
the
tracking
force
to
suit
the
built-in
pick
-up
cartridge
the
tonearm
is
balanced
with
the
scale
set
to
zero.
Coarse

ment
is
carried
out
by
moving
the
weight
with
the
stem
40,
the
subsequent
fine
adjustment
by
turning
the
weight.
The
tracking
force
is
adjusted
by
turning
the
graduated
rotary
knob
64
incorporating
a
coil
spring.
The
scale
has
markings
for
a
range
of
adjustment
from
0
to
30
rnN
(0
to
3
pl
which
permit
accurate
adjustment
of
the
tracking
force.
One
graduation
in
the
range
of
2

15
mN
(0.2

corresponds
to

in
the
range
of

30
mN
(1.5

to

The
vertical
tonearm
bearing
is
correctly
adjusted
when
it
swings
in
after

Tonearnn

Automatic

The

the
main

The
automatic
tonearm
set
down
mechanism
is
designed
for
30
cm
and
17
cm
records
and
is
coupled
to
the
platter
speed
changeover.
The
setdown
points
of
the
tonearm
are
determined
by
the
spring
pin
of
segment
185
contacting
the
slide
bar
190.
Limitation
of
the
horizontal
movement
of
the
tonearm
is
pro-
duced
by
the
pin
of

contacting
the
stop
attached
to
the
slide

190.
Only
during

does
main

lift
the
slide

and
the

attached
to

which,
as
a
result,
moves

slide
bar
is
released
again
and
returns
to
its

As
a
result,
the
slide
bar
moves
out
of
the
swivel
range
of
the

so
that
unimpeded
movement
of
the
tonearm
is
possible
for
playing.

Lubricating
instructions
All
bearing
and
friction
points
of
the
unit
are
adequately
lubricated
at
the
factory.
Replenishment
of
oil
and
grease
is
only
necessary
after
approx.
2
years
of
normal
use
as
the
most
important
bearing
points
have
sintered
metal
bushes.
The
motor
bearings
have
long-life
sintered
metal
bushings
'and
thus
should
not
be
lubricated.
Bearing
points
and
friction
faces
should
be
lubricated
sparingly
rather
than
generously.
When
using
dif-
ferent
lubricants,
chemical
de-
composition
can
often
take
place.
To
prevent
lubrication
failure,
we
recommend
using
the
original
lubricants
shown
below.
