All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.
F
ATTENTION
Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler le bracelet serti d’une résistance de
sécurité.
Veiller à ce que les composants ainsi que les
outils que l’on utilise soient également à ce
potentiel.

WARNUNG
Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.

Potential halten.
WAARSCHUWING
NL
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.

I
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevità potrebbe essere fortemente
ridatta in caso di non osservazione della più
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.
GB
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,

Power
Before connecting the AC power cord to the
wall outlet, ensure that the following are done;
-If your system is equipped with a
Voltage Selector, set the VOLTAGE
SELECTOR to the local power line
voltage.
- All other connections have been made.
WARNING!
-For optimal performance, use only the
original power cable.
-Never ma ke or change any connections
with the power switched on.
To avoid overheating of the system, a safety
circuit has been built in. Therefore, your
system may switch to Standby mode
automatically under extreme conditions
.
If
this happens, let the system cool down
before reusing it (not available for all versions).
B
Antennas Connection
Connect the supplied AM loop antenna and FM
antenna to the respective terminals. Adjust the
position of the antenna for optimal reception.
AM Antenna
Position the antenna as far as possible from a TV,
VCR or other radiation source.
FM Antenna
For better FM stereo reception, connect an
outdoor FM antenna to the FM ANTENNA
terminal.

Brief Introduction on the MPEG
1. When VCD source is selected the MPEG_RESET line will go positive triggering the following:
-DRST pulse to reset 8-bit microcontroller IC 7212
-RSTOUT# pulse to reset IC 7201 ES3880
-IC7212 sends CD10_RST to reset Signal Processor IC 7802 on the CD Board.
2. Communication will establish as follows:
-DSA_ACK, DSA_STB and DSA_DAT between µProcessor IC 7401 on the Front Board and IC 7201 ES3880.
-DSA_STB to IC7204 ES3883 to select between NTSC (Lo) or PALS (Hi)
-DSA_A, DSA_D and DSA_S between IC 7201 ES3880 and microcontroller IC7212
-SILD, SICL, RAB and SDA between microcontroller IC7212 and Signal Processor IC7802 on the CD Board.
3. Other activities between IC7201 ES3880 and Eprom IC7202, Dram IC7203 and IC7204 ES3883 will follows resulting in the
OSD display on the TV set connected to the Video out socket.
4. When play button is activated the I2S signal (IIS_SCLK, IIS_WCLK and IIS_DATA) from the CD Board will enter IC7201
ES3880 which will work closely with the Eprom IC7202 and Dram IC7203. Inverter IC7205 74HC04D serves to reconstruct
the Digital signal & level required by IC7201 ES3880.
8-2
NOTES:
5. Digital Audio information (AUDIOCLK, AUDATA and BCLK) will be send to DAC (Digital to Analog Converter) of IC7204
ES3883.
6. Analog output (AOL+, AOL-, AOR+ and AOR-) is amplified by the differential Op. Amplifier IC7207 NJM4560M.
7. Digital Video information YUV(0….7) will be send to the Video processing part of IC7204 ES3883 and out to the Video out
socket.
8. The HSYNC & VSYNC from IC7204 ES3883 to IC7201 ES3880 are to synchronize the Digital Video Information.
9. Mic Echo Input into IC7204 ES3883 is converted to digital signal (ARCLK, AIN and ARFS) for IC7201 ES3880 to combine
into the Digital Audio Information.

Brief introduction
General
1.
Playback Mode
Signal from the playback head Deck A or Deck B is selected and fed through by the Mode Selector IC7710 (HEF4952BT).
The signal is amplified by amplifier IC7720 (AN7323S) before feeding to the IC7740 (HEF4952BT) and out to the AF Board
via connector 1701.
Recording Mode
2.
Recording Signal is selected and fed through by the Mode Selector IC7710 (HEF4952BT) which is then amplified by the
amplifier IC7720 (AN7323S). The amplified output signal will pass through IC7730 (HEF4952BT) for record equalization and
back to IC7710 (HEF4952BT) before registered into the Rec/PB Head of Deck B.
3.
Dubbing Mode
In Dubbing mode, signal from the playback head Deck A is selected and fed through by the Mode Selector IC7710
(HEF4952BT) which is then equalised for playback mode by the amplifier IC7720 (AN7323S) so that a flat response is
obtained after the pre-amp. The equalised signal will then follow the same path as in the Recording mode.
Mode Selector
4.
The Mode Selector IC7710 (HEF4952BT) caters for 4 inputs signal, namely Playback Signal from Deck A, Playback Signal
from Deck B, Recording Signal and Dubbing Signal.
5.Amplifier PB/REC
Amplifier IC7720 (AN7323S) is for the purpose of amplifying the Playback and Recording signal from the Mode Selector.
6.
Automatic Level Control (ALC)
ALC circuit consists of resistors (3760, 3765, 3766, 3767), capacitors (2762 , 2763) and control by transistor 7787 (BC847B).
ALC limits the amplifier output to a constant value when input signal becomes too large, thus limiting recording current to
below saturation level, to prevent recording distortion.
Muting Circuit (For Non-Dolby version only)
7.
Switch S4 of the IC7740 (HEF4952BT) is for the purpose of muting the output during Recording mode. During Recording
mode, S4 is closed and shorted to the ground.
8.IC7740 (HEF4952BT)
The function of the IC7740 (HEF4952BT) is to change time constant between 120us Ferro (IEC I) and 70us Chrome (IEC
II) during playback mode. It will automatically determined whether the tape type is 120us Ferro (IEC I) or 70us Chrome (IEC
II). This IC will switch to Flat Gain during the Recording mode.
9.
IC7730 (HEF4952BT)
The function of the IC7730 (HEF4952BT) is to change gain and time constant according to tape type and recording speed
to boost recording current at higher frequency during recording to compensate for head loss. It will automatically determined
whether the tape type is 120us Ferro (IEC I ) or 70us Chrome (IEC II).
Bias Level
10.
Bias Level making use of the Variable resistor (3773) for adjusting the optimal level of the bias current for Ferro or Chrome.
11.
Bias Symm (For Dolby B NR version only)
Bias Symm making use of the Variable resistor (3785) to adjust the bias current for the left and the right channel to be equal.
PB Switch
12.
Playback Switch which consists of the FETs 7785 (For Dolby B NR version only) & 7786 (J111) is for the purpose of providing
a virtual ground for the Rec/PB Head (Deck B) during Playback mode. During the Playback mode, the FETs are turn on and
shorted pin 2 and 4 of connector 1720 to the ground. During Recording mode, the FETs are turn off to allow the oscillator
signal to be superposition onto the Recording signal for recording.
13.
Motor Speed (For FR versions only)
During High speed dubbing, a feedback signal from the uP through pin 03 of the IC7610 (HEF4094BT) will trigger the
transistors 7622 (BC847B) and 7616 (BC857B) to cause a change in the voltage level between High and Low, thus changing
the speed of the motor.
IC7610 (HEF4094BT)
14.
IC7610 (HEF4094BT) is a Shift Register use for issues the logic for cmos switch ICs (HEF4952BT) via 1A0, 2A1 and 2A2.
It also issues logic to On/Off SOL_A, SOL_B and MOT. Recording speed is controlled via NS/HS.
Dolby Circuit (For sets with Dolby B NR version only)
15.
IC7630 (CXA1551M)
IC7630 (CXA1551M) in the Dolby circuit is a Dolby Noise Reduction Type B IC for the Playback and Recording signal. Noise
Reduction ON/OFF are controlled by DOLBY, which is from CLK, direct from uP. After clocking in DATA, CLK is set to HIGH/
LOW for NR OFF/ON.
19kHz Filter
16.
The 19kHz filters 5631 & 5632 (LXD-210) in the Dolby circuit is for the purpose of filtering the 19kHz Pilot Tone (for Tuner
signal only) of the Recording signal.
17. Level Adjust
The Variable resistor 3635, 3636,3641 and 3642 in the Dolby circuit is for adjusting the playback level of the Dolby reference
(400Hz , 200nWb/m). Transistor 7631, 7632 are ON to enable adjustment of 3641, 3642 during Playback Deck A. Transistor
7633, 7634 and 3635, 3636 are active for Playback Deck B.
18.

Attention: In the POWER 2001 module the power amplifier IC AN7591 is used as a bridge-amplifier.
Any connection from output to ground will destroy the outpout stages!
• Via the AMP_ON control line, connected to pins 6 (Stby), the power amplifiers are switched on/off by the µP.
High level (approx. 4,5V): power amplifiers switched on
Low level (approx. 0V): power amplifiers switched off
• Super class G - operation
The power amplifiers operate as so-called super class G - amplifiers:
The supply pins 12 (Vcc) are not just connected to one fixed DC-supply as in conventional amplifiers.
Dependent on the output power there are three different DC-voltages supplied to the power amplifiers:
⇒ +C1 (+20V) for low output power
⇒ +B1 (+29V) for medium output power
⇒ +A1 (+41V for high output power

(30 - 70W Version)
Circuit details continued:
• Low power standby feature
An additional small standby transformer, reduces power consumption in standby-mode.
In case power is switched on, the control line ECO is low → relay 1210 is activated → contacts 1 and 2 are closed →
transformer 5001is connected to mains.
When the set is switched off (standby) the control line ECO is high → relay 1210 is not activated → mainstransformer is
disconnected. Via standby transformer and rectifiers 6210-6214 the supply voltage LOW_PWR_SUP is substituted. This
voltage is always available and so the microprocessor is kept running.
• DC voltages +A1, +B1, +C1
These voltages supply the Super Class G amplifier, described on previous page.
The whole power supply is optimized for the special characteristic of this type of amplifier. For that reason several “tricky”
details have been applied to ensure optimal efficiency and symmetrical load to the mains transformer.
Generation of +A1
Common full wave rectifying with bridge rectifier 6202, using 100% secondary winding of mains transformer (pin 10-14).
Generation of +B1
The supply for +B1 consists of one full wave rectifier:
– 2 diodes of bridge rectifier 6202, with 6200(6220 in parallel) 6201(6221 in parallel) for generation of +B1using approx.
70% secondary winding of mains transformer (pin 10-13 respectively pin 11-14).
As example for generation of +B1 see picture 1.
Generation of +C1
Full wave rectifying with 2 diodes of bridge rectifier 6202, using 50% secondary winding of mains transformer (pin 13-15/13-11).
See picture 2 below.

BRIEF INTRODUCTION OF THE AF9 BOARD
The AF9 Board consists of the following features :
a. TDA7468D IC
TDA7468D IC (7501) which includes functions such as source selection, loudness control, dynamic bass control, treble
control, volume control and muting function. Sound features such as ALC, DBB, DSC and IS are controllable via I2C Bus
from the microprocessor.
The TDA7468D IC caters for 4 input sources namely TUNER, TAPE, CD and AUX. It also has a Mic mix input. In our
application, software will switch the input source to previous source MUTE during STANDBY mode and some other
occasions where noise from other input source is undesirable.
