1. Audio circuit (Circuit diagrams Main PWB)

1.1 Audio input

The audio signal input received from the audio input terminal (JK011) is applied to the amplifier I001 of 4
(L-CH) and 9 (R-CH) through the low-pass filter consisting of R040, R041, R042, R043, C040 and C041.
In this amplifier, controls of Volume, and mute are conducted. The audio signal controlled at the pin 6
determines the attenuation of output of the amplifiers. Since then, the signal is output to the jack P003.

1.2 Audio output

The audio signal is output from the Audio output terminal (P003) of the jack board to the internal speaker
system.

2. Power supply (Circuit diagrams MAIN PWB)

1. Line filter consists of C801, T801, C803, C804. It eliminates high frequency interference to meet EMI’s

requirement.

2. Rec & Filter

Bridge diode D801 converts AC source into pulsed DC. This pulsed DC is smoothed and filtered by C805.
R802 is an NTC ( negative thermal coefficient ) resistor, used to reduce inrush current to be within safe
range.

3. Power transformer :

T802 converts energy for square wave from power source C805 to secondary side to ge12V and
+5V.

4. Output :

The square wave from T802 is rectified by D809, D810, then filtered by C817, C822 to ge12V
and +5V respectively.

4.1 A 5V power supply for LCD module, CPU and logic is generated from the power source.

4.2 I310 : 3-terminal regulator

A 3.3V power supply for I306 analog is generated from the 5V source.

4.3 I310 : 3-terminal regulator

A 3.3V power supply for I306 digital is generated from the 5V source.

Q303, Q304 ON/OFF control for LCD Module

ON/OFF control is performed for power ON/OFF and also for the power saving sequence.

5. Driver : Q803

If the electrical potential of gate is larger than source by about 10 volts, Q803 turns on.

6. FB :

Negative feedback CKT consists of photo coupler I802 and adjustable regulator I803. It can maintain
output vo5V and +12V at a stable level.

7. PWM :

7.1 Start : When power is turned on, R805, R803 conducts due to bias from C805. C807 is charged a 16 volt

and a starting current to pin 7 of I801. I801 starts to oscillate and outputs a pulse train through pin 6 to
drive Q803.

7.2 OPP : When Q803 turns on, C805 supplies a linearly increasing triangle current through the primary

inductance of T802 to the driver Q803, once the peak value of this current multiplied by R811 exceeds1
volt, pulse train will be shut down immediately to protect Q803, T802 from being burned out.
