5. CIRCUIT
DESCRIPTIONS
The main circuit configuration is outlined in the
block diagram
on page
15.
5.1 SIGNALPATH
Recording
Mode
The input signal from LINE INPUT is passed
via
the INPUT volumecontrol, flat amplifier andMpX
filter before being applied to the Dolby NR circuit.
The Doly NR circuit output is then applied to
the recording amplifier equalizer where the fre-
quency response
is regulated
according
to the type
of tape being used before finally being applied
to the recording
head.
Playback
Mode
The playback head output signalis applied to
the playback equalizer (gain 5B.2dB) where the
frequency response is corrected according to the
type of tape being used. Following this, the signal
is passed via the MPX filter to the Dolby NR
circuit, and
then
via
the REC/PB
switch
(HA1200b
elechonic switch) and MUTE switch (HA12006
electronic switch) to the LINE OUTPUT as the
playback output signal.

TapeTransport ModeSwitching
Pins 1, 2, 3 and 5 of IC402 (8A834) are the
input pins for PLAY, STOP,FF and REW. When
any pin is switched to L level, the tape deck
is switched to the conesponding transport mode.
For example, when 52 and S3 are switched on,
pins 1 and 2 of. IC404 are switched to L level,
resulting in the OR gate output pin 3 also being
switched to L level. This is followed by pin 1
of.1C402 being switched to L level,thereby switch-
ing the deck to play mode. Likewise, SB and 54
are switched on for fast forward mode, 52 and Sb
for rewind mode, and 54 and 55 for stop mode.

5.3 MUTING
CIRCUIT
Muting Gate
The LINE OUTPUT muting gateis incotporated
in IC401 (H412006), the output being muted
when pin 15 of this IC is at L level and pn 2 at
H level.
Pin 15 is connected to the PLAY output of the
operating mode control IC (8A843) and is switch-
ed to H level only during playback mode. +B is
applied to pin 2 vn R478 and,
R477, and the pin
is kept at H level except when Q426 is turned on
during recording mode. In this way, the line output
is muted during fast forward, rewind, stop and
play pause modes, and cancelled during playback,
recording and recording pause
modes.
Fig.

LINEOUTPUTmutins
The recording amplifier input muting gate is
gloundconnected by transistors
(Q103 and Q104).
The basesof these hansistors areconnected to pin
2 of HA12006 via R145, R143, R428, D427,
D429 and R477, thereby enabling muting to be
cancelled during recording mode. fhrring rec mute
mode, however, these bansistors are turned on,
resutling in the recording of blank sectionsof tape.

Auto-Stop
Circuit
This circuit is used to switch the mechanical
driveconbol IC (BA843)to stopmodewhen
tape
transportstops
(see
Fig.5-11).A photo-intemrpter
is used for tape
transportdetection,
andtherotary
blademechanismusedto intemrpt the light beam
iscoupled
to thetake-upreelby belt.
During
TapeTransport
1. Q401 is turned on and off repeatedlyby the
photointernrpter output, resulting in C403
being chargedup and discharged
againin re-
peated
cycles.
When
TapeTransport
Stops
When the take-up reel stops at the end of the
tape, Q401 ceases
switching on and off due to
the lossof the photo-intemrpter output.
With a current being passed
from +B to C4O3
via R405 and R406, C403 is charged up and
the Q402 base potential increases, resulting
in Q402 being turned off. Q403 isthus turned
on and pin 2 (STOP) of.tC402 is switched to
L level, thereby switching the deck to stop
mode.

Whenthe Pornær
is Switched on (SeeFig. 5-91
When the power is switched on, +B is passed
via
C4O4 and R415 to Q40G, being turned on for
about 1.5 to 2.5 seconds
(until C404isfully charg-
ed). This results in pin 2 (STOP) of IC402 being
switched to L level, thereby ensuringthat the deck
is orginally in stop mode. If any other switch is
pressed during this initial brief period, the deck
will remain in stop mode. +B will, however, be
applied to the capstan motor and the motor will
startup.
Playback Mode
When the PLAY switch (S2/SB)
ispressed,
pin 1
(PIÂY) of.tC4O2 is switched to L level and pin 12
(O-PLAY) to H level. +82 is thereby passed
via
F"423 and R424 to Q410, rezulting in this transist-
or being tumed on. The pinch solenoid SOL is
consequently activated and playback mode com_
menced(see
Power.Assist
Mechanism).
Recording
Mode
1. Iilhen a cassette half with the erasurepreven-
tion tabs intact is loaded into the deck (result-
ing in the erasureprevention switch S10 being
switched to the NO HOLE position) and SZ
switched on, pin 10 (O-REC) and pin 12
(0-PLAY) of.IC4O2
switched
to H level.
2. The pin 10 output is applied to the base of
Q426 vira
R481. With e426 turned on, pin 2
(REC signal input) of. IC4OI is switched to L
level. And since pin 12 is at H level, pin 1b
(PLAY signal input) of IC401 is switched to
H level resulting in pin 6 (headswitch) and pin
16 (recording/playback switch) of IC401 also
being switched to H level. The recording input
shorting relay RY301 in the record/playback
head circuit is openedand the playback output
shorting transistor Q101 is tumed on (thereby
switchingthe head
to recordingmode).
3. With'pin 10 of IC4O2
andthe playback output
shorting transistor Q301 is turned on and the
biasoscillator activated.
If a cassettehalf without the erasure preven_
tion tabs is loaded, S10 is switched to the
HOLE position, resulting in pin g (À-R) of
IC4O2 being switched to L level. In this state,
the tape deck will not be switched to recording
mode when pin Z (EE-C)
is switched to L level.
Fast Forward Mode
When the FF switch (Sg/S4) is pressed,
pin 1b
(0-FF) of.1C402 is switched to H level, reiulting
in +32 beingpassed,
to e40T via R4LT and R41g.
And once Q407 is tumed on, the FF solenoid
is activated to start fast forward mode.
Rewind Mode
When the REIV switch (S2lSb) is pressed,pin
13 (O-REW\ of.lC4O2 is switched to H level,result-
ing in +82 being passed to Q408 via R420 and
R42L, thereby turning Q408 on to activate the
REW solenoid for start of rewind mode.
Time Playback
Mode
Tape playbaek is started automatically at the
time set by the timer.
1. I{hen the power is switched on with the
TIMER switch S11 on and S12 set
to play, +B
is immediately passedto Q411 via C406 and
È426, thereby tuming Q411 on for about Bto
5 seconds (until C406 is fully charged). In
addition, +B is applied to Q406 via C404 and
R415, resulting in Q406 being turned on for
about 1.5 to 2 seconds(until C404 is fully
charged). As a rezult, pin 1 (Pf,Ây) and pin 2
(STOP) of.IC OZareswitched to L ievel. -
2. lflhile pin 2 remains at L level, stop mode has
priority over all other modes, and pin 12
(O-PLAY) of. 1C402 is switched to L level.

3. Q406 is turned off once C404 has been fully
charged up, resulting in pin 2 of.l0402 beng
switched to H level (L + H). Since Q411 is
on at this time, pin 1 of ICAOZ will be at L
level, and pn 72 will be swiôched to H level
(L - H). Q410 will thereby be turned on,
and the pinch solenoid SOL activated as des-
cribed abovefor playback mode.
Timer Recording
Mode
The tape deck is started up automatically in
recording mode at the time set by the timer.
1. \[hen the power is switched on with the
TIMER switch S11 on and S12 set to REC,
Q406 and Q411 are turned on for several
seconds in ttre same $'ay as described above
for timer playback mode. As a result, pin 1
(PLÂY), pn 2 (SIO=P) and pin ? (EE-C) of
IC402 areall switched to L level.
2. During tlre period that pin 2 of. IC4O2 is at
L level, pin 10 (0-REC) and pin 12 (O-PLAY)
of the same
IC arealsoat L level.
3. Once C404 is fully charged, Q406 is turned
off, resultingin pin 2 of.lC4O2being
switched
to H level (L + H). And since pins 1 and ? of
IQ402 are at L level at this time pins 10 and 12
are switched to H level (L + H), thereby
resulting in the start of recording mode (see
normal recording mode for further details.
MSOperation
\{hen the MS switch is turned on and either the
FF or REW switch pressedduring tape play, the
tape will be stopped at an unrecorded blank
section of tape between tunes, and then switch
automatically to playback mode.
1. \{hen the FF switch (S3/S4) is pressed vdth
the MS switch S13 tumed on, pin lb (O-OFF)
of IC4O2 is switched to H level, thereby
enabling Q407 to be turned on (fast forward
standby mode) by the Q419 inhibition circuit
describedlater.
At the same time that pin 15 is switched to
H level,pin 14 (0-FAST) is alsoswitchedto H
level,
rezulting
in Q417 being
turned on.
Once Q417 is tumed on, Q418 and Q419 will
be tumed on for a period of time determined
by the C425|P"44Otime constant. And while
the Q419 inhibition circuit is on, the e40Z
basepotential drops, resulting in the transistor
being turned off to put the deck into fast
forward standby mode.
Pinch solenoid SOL. 1 is activated by the
cunent passed from Q418 to Q410 via R445
and D413 (one-kick power-assiststart), result-
ing in the headbasebeingraised.
Also as a result of Q417 being turned on,
Q421 is turned on by q420 after a delay
determined by the C4261R"446time constant,
thereby activating the MS solenoid SOL.
Upon completion of power-assist, the head
base is move to the MS position, the fast for-
ward standby mode is cancelled, and tape
transport proceeds in fast forward mode.
And since pin 6 of IC403 is switched to H
level, IC403 is switched to MS standby mode.
During this fast forward tape transport, pin 3
(input terminal) of IC403 (for inter-turn blank
detection) accepts the fast forward playback
signal(flat amplifier output signal).
If this input signal is intenupted for about
84ms, a pulse is obtained from pin 8 (output
terminal), the width of the pulse being
determined by R431 and,
C423. Q4L4 istumed
on by this pulse signal, resulting in pin 1
(PLAY) of. îC4O2 being switched to L level,
and the tape deck being switched to playback
mode.
A similar sequenceis also followed when the
RElfl switch is pressed instead of the FF
switch.

5.5 FUNCTIONSELECTOR
ïVhen ttre CT-X50 is used with the A-X30 or
A-X50, this function selector circuit passes
signals
to the A-X30 or A-X50 indicating the tape deck
operational status.
IC405 (M51202L) receives output signals via
diodes D409, D408 and D432 from different
1C402 (8A843) output pins during different opera-
tional modes. During playback, fast forward and
rewind modes, pin 1 of IC405 is at a higher po-
tential than pin 2, resulting in pin 3 being switched
to L level. If t'Lre
deck is then switched to record-
ing mode, the D432 cathode is switched to H level
and the D409 and D408 cathodes are switched to
L level. with the D432 cathode at H level, pin 2 of
IC405 is switihed to a higher potential than pin 1,
resulting in pin 3 being switched to H level. Pin 3
is also switched to H level during stop mode due
to +B being applied to pin 2. C443 and C442
have been inserted in order to prevent misopera-
tion during mode switching (use is made of the
time constants of thesecapacitors during eachtype
of modeswitching).

5.6 AUTO TAPESELECTOR
Tape selection of normal, chrome and metal
tapes in the CT-X50 is performed automatically
by detecting special detector holes in the respec-
tive cassettehalves.The presence/absence
of these
holes is detected mechanically by S14 and S15.
Depending on the rezultant switch combination,
the required supply voltage is applied to the
oscillator circuit in order to obtain the appro-
priate biaslevel for each
type of type.
