IC5 : TDA7340P (X14-1523-10)
Description
The TDA7340 I?C bus controlled audio signal proces-
sor contains all signal processing blocks of a high per-
formance car radio, including audio processor, stereo
decoder, noise blanker, pause detector and different
mute functions.
The use of BICMOS technology allows the imple-
mentation of several filter functions with switched ca-
pacitor techniques like fully integrated, adjustment free
PLL loop filter, pilot detector with integrator and two
19kHz notch filters.
This minimizes the number of external components.
Due toa highly linear signal processing, using CMOS-
switching techniques instead of standard bipolar multi-
pliers, very low distortion and very low noise are ob-
tained also in the stereo decoder part. The audio pro-
cessor contains several new features like soft mute,
zero-crossing Mute and pause detector.
Very low De stepping is obtained by use of a
BICMOS technology.

LOADING
1. Insert a cassette tape ( @).
~
The pack slider (50) presses the lever (49) (@).
3. The lever (49) rotates and the push plate (58) lock
releases. The push plate is pulled by spring (59)
and moves forward ( @).
4. The holder (48) lowers following the groove in the
push plate (58) ( @).
5. The slide switch (S1) is pressed by the push plate
(58) and turns ON. When S11 turns ON, current is
Supplied to the motor (M1) ( @).
12

KRC-356D/L/N
MECHANISM OPERATION DESCRIPTION
6. The push arm (83) is pressed by the push plate (58)
and rotates. The push arm (83) releases the head
plate (2) lock ( @).
7. The head plate (2) is pulled forward by the spring
(80) ( @).
8. The forward movement of the head plate (2)
causes the push switch (S2) to turn ON (@).
9. Through the forward movement of the head plate
(2), the PR spring (4) causes the pinch roller as-
sembly (16, 17) to press against the capstan as-
sembly (74) (@).
10. The rotation of the motor is transmitted through
various gears (78 > 25 + 31 > 6 -) to drive the
winding side reel disk assembly (22) ( ®).
11. The sending side reel disk assembly (22) is not
driven by the motor rotation because it is sepa-
rated from the play gear (6) (@).
13

KRC-356D/L/N
MECHANISM OPERATION DESCRIPTION
PROGRAM (Manual Program Change)
1. When pressing FF/REW (92 and 93) levers at the
same time (@), the levers are placed into a slot on
the PC (Play Change) plate (94) in direction of arrow
( @) in Fig.7.
2. The PC plate (94) moves in the direction of arrow
( &), trigger arm (81) is kicked in the direction of
arrows ({ €@}) and ( @), thereby releasing the turn-
over gear (27).
3. The turn-over gear (27) is rotated in the direction of
arrow ( @) by ED (End Detector) gear (26), which
moves main plate (64).
4. The main plate (64) slides in direction of arrow (@) 20
in Fig.8 causing the following part movements;
a) Head switch (10) movement is changed per ar-
row (@).
b) Force transferred from pinch roller-spring (4)
changes the relation of pinch roller and capstan
to each other, per arrow ( @).
c) Seesaw plate (20) is moved by the main plate
and seesaw plate spring (65), and moves see-
saw working plate (84). All FF/REW operation is
performed by this seesaw plate movement. See
arrow ( @).
d) The shift plate (11) is moved in direction of arrow
(®), and head moves up and down per arrows
(®, Band®) in Figg.

take-up reel assembly in REV play. Rotation from
the play clutch (31) is transferred to take-up reel
assembly per arrows (®@ ) and (®) in Fig.11. As
mentioned above, the direction in play mode can
be changed. During play mode active, the head
panel is moved backward by head panel return
arm (88) in direction of arrow ( @) in Fig.11. The
Mute switch (S2) is turned on per arrow ( @),
and play mode is not reversed while FF/REW
levers are pushed by operation of anti-reverse
arm (33). See Fig.12.

line A of 2-line tape passes through the center of the head
shield plate (white section).
e During REV transport, adjust screws ® and ®)' so that
line B of 2-line tape passes through the center of the
head shield plate (white section).
e After the alignment above, reverse the transport direction
and check the FWD alignment again. If it is deviated,
perform alignment again. (Tape used: SCC-1659, manu-
factured by A-BEX).
