SAFETY INFORMATION

1. SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground

{water pize, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA.

Leakage current tester

Reading should

not be above

0.5mA

Test all

exposed metal

surfaces

2-wire cord

@ Also test with

plug reversed Earth

(Using AC adapter ground

plug as required)

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A PO. TENTIAL SHOCK HAZARD AND MUST BE COR- RECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

2.PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance

have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual.

Electrical components having such features are identified

by marking with a A\ on the schematics and on the parts list in this Service Manual.

The use of a substitute replacement component which

dose not have the same safety characteristics as the

PIONEER recommended replacement one, shown in the

parts list in this Service Manual, may create shock, fire,

or other hazards.

Product Safety is continuously under review and new

instructions are issued from time to time. For the latest

information, always consult the current PIONEER Service

Manual. A subscription to, or additional copies of, PIONEER

Service Manual may be obtained at a nominal charge from

PIONEER.

10. ADJUSTMENTS

10.1 MECHANICAL ADJUSTMENTS

Prior to Adjustment

Clean the both reel base, the capstan and the

pinch roller with an alcohol moistened swab.

Pinch Roller Pressure Adjustment

1. Put the tape deck into the playback mode.

2. Gently push against the pinch roller arm with

the tension gauge and separate the pinch roller slightly from the capstan.

3. Then the pinch roller back onto the capstan, and read the value when the pinch roller starts

to rotate. If the reading faiis to lie within

300 ~ 500g, replace the pinch pressure spring.

Tension gauge

Pinch roller

Fig. 10-1 Pinch roller pressure adjustment

Reel Base Torque Adjustment

Measure the torque with the torque meter during playback, fast forward (FF) and rewind (REW) modes. The measured values should normal- ly lie within the allowably ranges listed in the table 1. ,

If the measured values lie outside the relevant ranges, replace the TU (take-up) reel base assembly and/or supply reel base assembly, TU idler, or drive arm full assembly.

Tape Speed Adjustment

1. Load the STD-301 test tape into the deck I,

and any blank tape into the deck II.

2. Press the SYNCHRO COPY START key and let the deck warm up for at least ten seconds.

3. Short circuit between the TP16 and TP17 terminals. (double speed playback)

4, Check that the deck I playback frequency is

6000Hz+20Hz. If the frequency lies outside

of this range, adjust V303 to 6000Hz+20Hz.

5. Open circuit between the TP16 and TP17 terminals.

6. Check that the deck I playback signal fre-

quency is 3000Hz+5Hz. If the frequency lies

outside of this range, adjust V301 to 3000Hz +5Hz.

7. Load the STD-301 test tape into the deck II.

8. Press the deck II PLAY key, and short circuit

between the TP16 and TP17 terminals,

9. Adjust V304 to obtain a double speed play-

back frequency within +10Hz of the adjusted value in deck I.

10. Open circuit between the TP16 and TP17 terminals.

11. Adjust V302 to obtain a normal speed play-

back frequency within +5Hz of the adjusted value in deck I.

12. CIRCUIT DESCRIPTIONS

The CT-1060W (CT-S77W) Stereo Dual Cassette Tape Deck features two separate cassette deck sections — one for recording and playback,

and the other for playback only. g

12.1 OUTLINE OF MAIN SECTIONS

Playback Equalizer

A low-noise operational amplifier IC (M5220L)

is used for both deck I and II. Playback equaliza-

tion is switched to match the type of tape by

transistor switching of the equalizer element in the equalizer amplifier output circuit. This switching is

automatic when the chrome tape detector hole is

detected in deck I, but requires manual switching of the TAPE SELECTOR switch in deck II.

@ CUE and REVIEW signal attenuator

When deck I is switched to cue or review mode,

the transistor switch in the output stage of the

playback equalizer circuit is turned on, resulting

in the high end frequency response being lowered in addition to the overall level being reduced.

(Deck I is switched to cue or review mode by

pressing the FF or REW button together with the PLAY button. The RELEASE button is pressed

to release the FF or REW key and return to normal playback mode.)

mS 6 46 6.

Fig. 12-1 Block diagram of AN6886

CT-1IO60W, CT-S77W

Dolby NR Section

An IC (HA12058NT) is used to switch to type B or type C Dolby NR. When in copy mode, the

Dolby NR section is bypassed, the deck I playback

signal being recorded directly in deck II.

Recoding Amplifier

Employing an operational amplifier IC

(M5218L), the required recording characteristics

are obtained by switching peaking elements in the feedback circuit.

Level Meter

A 5-point LED drive IC (AN6886) equipped with two input circuits is used to connect and

combine left and right channels and drive the logarithmic (dB) bar type meter.

Control Section

Signal and indicator circuits are controlled by a

microcomputer (PD4061). (See 12.3 “Signal and

Indicator Circuit Control”’.)

12.3 SIGNAL AND INDICATOR CIRCUIT CONTROL

The signal and indicator circuits are controlled

by the PD4061 microcomputer. The tape transport

units in this model are switched to the various operating modes mechanically by the respective

mode buttons. (Since the capstan motor is used as

a drive source, the mode buttons can be operated

by light touch.) When the COPY buttons is pressed

to start tape copy mode, both tape decks are

switched mechanically — tape I (on the left hand side) to playback mode, and tape II (on the right

hand side) to recording mode. Although there is

no need for microcomputer control of the tape

transport mechanism itself, signal circuit switching,

muting circuit timing control, and indicator

control is all handled by the microcomputer.

PD4061 Specifications

1. System Clock

System clocks are generated by an RC oscillator employing a built-in oscillator circuit. Oscillating

frequency is 200 kHz. The specified timing set time is the set time when

the system clock frequency is 200 kHz.

2. Input Reception Conditions

Input sampling of 5 to 10 ms prevents chattering

when inputs are received, and also prevents mis-

operation by external noise.

3. Relay Play Mode A major feature of this tape deck is relay play-

back from deck I to deck II and from deck II to

deck I. The method used to set relay playback

mode involves stopping the motor of one or both decks by the relay play switch, and putting one of

the decks into playback standby status (*1) in advance.

Deck I is switched to playback mode when the deck I PLAY button is pressed while in relay play-

back ready status, and deck II is switched to play-

back standby status (*1) when the deck II PLAY

button is pressed after that. When deck I stops again (*2), the deck I motor stops turning (*3) and the deck II motor starts up to switch deck II from

playback standby mode to regular playback mode.

That is, playback mode is relayed from deck I to

deck II, and the operation is the same when play-

back mode is relayed from deck II to deck I. This

operation can be executed repeatedly by simply

pressing the PLAY button of one deck while the

other deck is in playback mode.

Fig. 12-4 PD4061 Pin layout

CT-1I060W, CT-S77W

The tape transport units feature a power assist

mechanism where capstan torque is used as a source of drive power to move the head base. If

the PLAY button is pressed while the motor is

stationary, the capstan does not come in contact

with the pinch roller, nor does the head come in

contact with the tape.

Relay playback can be activated when either

RELAY PLAY indicator I or II is on, or blinking on and off.

*1. PLAY button is in pressed status with the motor off.

*2. When the deck playback detector switch is turned off.

*3. Motor does not stop if the deck FAST detector switch is on.

@ Relay playback mode start conditions

(1) The COPY switch must be off.

(2) Deck II must not be in recording or recording-

pause mode.

(3). Both decks must not be in playback (or

playback-pause mode together.

The PD4061 is receptive to RELAY PLAY inputs

only when the above conditions are satisfied. The

subsequent outputs are listed in Fig. 12-3.

@ Relay playback mode cancellation conditions

(1) RELAY switch pressed a second time.

(2) COPY switch pressed (switched on). (3) Deck IH switched to recording or recording-

pause mode.

Relay playback mode is cancelled, and RELAY

indicator I or II is switched off when any one of

these conditions is met. If the FAST detector switch comes on during relay playback mode, the

corresponding motor output is switched to H level (but only while the detector switch is on). That is,

the deck which is not in playback mode can be

switched to fast forward or rewind mode.

4. Copy

Playback sound from deck I can be recorded in

deck II by this copy function at two different speeds — normal speed and double speed.

During double speed copying, the x1 output pin

is at ““H” level, and the x2 output pin is at “L”

level. COPY and SPEED switch inputs can be received

at any time. When not in normal or double speed

copy mode nor in the special modes indicated in

Fig. 12-5, COPY indicators I and III come on (“‘H” output) when the COPY switch is switched on, and COPY indicator II comes on (‘‘H”’ output) when

the SPEED switch (high speed) is switched on.

# denotes that although the PLAY and FF buttons have been pressed together, the tape trans-

For example, REW*# denotes the mode where the PLAY, REW, and PAUSE buttons have all
