5.1CH input mode: Now A/B/5.1CH control pins of M62446 are in high level.
L/R channel signals of 5.1 input terminal is outputted from pin 3/13 of N101
and sent to IC N106 for volume and tone adjustment; meanwhile, C/SR/SL
signals of 5.1CH input terminal are outputted from pin 14/15/4 of N102 and
then respectively sent to IC N106 for independent volume adjustment. And SW
signal of 5.1CH is outputted via pin 4 of N103 and then sent to M62446 after
being amplified by N107A.
Three analog input modes: AV250T totally has three analog input modes:
digital tuning demodulation signal, VCD and DVD, which are controlled via A/B
signal respectively.
AV250T totally has three sound field modes: Standard, Cyber Logic and Hi-Fi.
1. Standard: Under the control of overall CPU, when bass enhancer is off, L/R
channel and subwoofer output are available; when bass enhancer is on,
only L/R channel output is available.
2. Hi-Fi: Under the control of overall CPU, only L/R channel output is available
to M62446.
3. Cyber Logic: Pin 9/10 of electronic switch N101 (CD4052) select a group of
analog L/R channel input signals according to the truth table. L/R signals
are outputted from pin 13/3 via the internal electronic switch of N101, and
divided into two ways. One way is respectively sent into pin 13/15 of
M62446 for electronic volume and tone adjustment. The other way
produces SW/S-SR/S-SL and S-C signals via buffer, adder-subtractor and
low-pass filter. S-C/S-SR/S-SL signals are sent to pin 12/2/5 of N102. N102
select Cyber Logic signal input (see CD4053 truth table) from Cyber Logic
and 5.1Ch signals, outputs C/SR/SL signals from pin 14/15/4 and sends
into pin 11/8/9 of M62446 for volume adjustment. Still another way of SW
signal directly sends to pin 6 of M62446 after being outputted from N107A.
5.1CH signal sent into M62446 is outputted from pin 31-36 after volume
and tone adjustment, and then outputted to signal board by XS20 power
distributor.

2.2.2 Control circuit
Pin 23/26/27 of CPU (N100) output data, PVST and clock signals send to pin
39/40/41 of M62446, control pin 1/2/3/4 of M62446 output control level, so as
to select input signal and spectrum sampling signal. It is worth noting that
PVST signal is a latch control signal. When data and clock of CPU are sent to
M62446, an identification signal will be added, indicating that this signal can
only be used by M62446 while other IC of I2C bus cannot use current data and
clock signal.
2.2.3 Frequency spectrum sampling circuit
Only S-C/S-SR/S-SL/SW signals are sampled during frequency spectrum
sampling in AV250T and added to pin 14 of N103 via a 150K sampling resistor.
Another S-C cyber logic signal is added to pin 1 of N103, called S-C＇. 5.1CH
and LR-T of M62446 select sampling signals. When cyber logic is selected, the
control signal of 5.1CH is of low level while pin 9/11 of N103 is of low level.
According to the truth table, it is known that the outputs are X0/Z0. Sampling
signal is grounded while LR-T is of H level. Select Y1, S-C＇signal is outputted
from pin 15 of N103 to N108B, adding to OK-R signal for the amplification of
frequency spectrum signal, and then sent to frequency point gating and auto
search circuits via XS20.
2.2.4 Tuning function
The tuning function directly controls tuner and receives audio frequency signal
mainly via CPU and then outputs after amplification via power amplifier. The
clock and data line of tuner are shared with LM62446 and the other two control
lines are connected to CPU directly. L, R signal processed by the tuner can be
sent to N101 IC CD4052 directly to input the selected channel.
Section Three Signal processing board
The signal processing board superposes, mixes and amplifies 5.1CH signal
sent from the volume board, voice signal from the voice board and Karaoke
signal.

2.3.2 Flow chart of Karaoke signal
When the microphone is inserted, MIC signal is sent via MIC to the transmittal
circuit combined by N201A for amplification. Amplified MIC signal gives CPU a
MIC identification signal after N202A amplification, followed by VD201
rectification and filtering control triode V200. CPU sends PKM signal, which is
of low level, causing cutoff of triode V103/V105 and enabling output of MIC
signals; another way reaches pin 6 and 11 of PT2315 after C219/C222
coupling, outputs from pin 16/17 after internal volume and tone control, mixed
into one way and sent to N202B and then reversely send to N203B for
amplification. Signals amplified by N203B are divided into two ways: one way
is directly outputted; and the other way is outputted from pin 14 after being
coupled by R222/C247 to PT2399 for internal delayed echo adjustment,
reversed by N204B and outputted by mixing with karaoke signal. While OK-R
is outputted from pin 14 after being gated by N205 and superposed to L/R
channel.
In this circuit, the bass boost network made up of triode V201 connected to the
negative terminal of N202B is primarily for bass boost of 75HZ low frequency
signal.
During delay adjustment for PT2399, first control signal is given to CPU, which
controls N207 after being expanded via N211 IC CD4094 and connects with
pin 6 of PT2399 by selecting different resistance values for purpose of delay
adjustment.
Echo control is to change the resistance value at the connection point to R229,
so as to change the superposition on through connect signal for echo control.
The wide sound field processing control signal of SOK’s karaoke is in wide
sound field mode when it is high level, and now the signal of OK-R is the OK
signal inverted by N204A.
A sense signal of OK-SW on the MIC plug detection together with the network
made up of V200. When MIC is not plugged, it is low level; when plugged, it is
of high level.
Karaoke auto mute function is also available. When P-KT fails to detect signal
for a continuous period, CPU will send a P-KM signal to mute karaoke and
avoid MIC receiving noise, which may affect on sound effect.
Signal flow chart of scene mode
AV250T has a special function that switching between 5 scene modes is
available without karaoke, which is fulfilled through part of karaoke.
When pin 9/10 of N205 are of high level, sampled L/R/C signals are outputted
via pin 3 through N205 gating. After amplification by N203, one way is
connected directly; and another way is sent to internal of PT2399 for echo
delay adjustment (controlled by IC CD4049), with the adjusted effect
superposed to L/R/C channel to form different scene modes.
In this circuit, MIC shall not be inserted and is only available in 5.1CH mode.
N203A is for the purpose of reversal.
In addition, this device is added headphone output function. PHSW is low level
and each channel has output when headphone is not inserted. But when
headphone is inserted, PHSW will be high level for the mechanical settings
thus LRM and SCM signals change into high level at the same time to realize
muting in each channel, so the signal is only outputted from headphone, that is,
there is not signal output with each channel when connecting with headphone
output.
2.3.3 Bass enhancer circuit
P-BURST is the switch signal of bass enhancer. When it is of high level and
added to the base electrode of V102, V102 will be switched into conduction.
When the collector electrode outputs low level, V107 will be cutoff; when the
collector electrode is of low level, V100 will also be cutoff. SW signal is
normally outputted to external terminal. Meanwhile, the high level signal of
P-BURST is added to the emitter electrode of V108. V108 is positively biased
and switched into conduction. The collector electrode adds high level to the
base electrode of V101. V101 is positively biased and switched into conduction,
and ground SW signal, not superposing it to L/R signal.
In reverse, when P-BURST is of high level, V100 will be switched into
conduction and SWM cannot be outputted from external terminal. Meanwhile,
V101 is cut off and SW signal is superposed to L/R channel signal.
The bass enhancer of AV250T can be divided into three steps. This principle is
to change the volume of bass enhancer by changing the SW output volume of
M62446.
2.3.4 Mixing and amplification circuit of 5.1 signal and karaoke signal
When L/R channel signal of 5.1 signal is superposed with SW signal and
amplified by N101B/N100B, it is sent to the reverse phase of N101A/N100A.
Meanwhile, OK-R/OK-L signals are also respectively added to the reverse
phases of N101A/N100A. After mixing and amplification by N100A/N101A,
they are respectively outputted from pin 1 of N100A/N101A to power
amplification circuit for power amplification.
Meanwhile, the C-1 signal sent by volume board is added to the reverse phase
of pin 6 of N102B and added to the reverse phase of N102A after amplification.
Now C1-1 signal after electronic echo processing is also added to the reverse
phase of N102A and sent to power amplification circuit after mixing and
amplification.
SR-1/SL-1 of another volume board is also added to the reverse phase of
N103B and N104B for amplification and then sent to N103A and N104A for
further amplification, and later sent to power amplification circuit.
One way of 5.1 signal after being mixed and amplified is sent to power
amplification circuit passing through XS9, and the other way forms DIST

R111-R113/R142/R145/VD100-VD104, which will be added to CPU for
automatic gain adjustment, so as to control volume output.
Section Four CPU board
2.4.1 CPU control unit
N100, the overall CPU, is the overall control center, inputting all kinds of
control instructions to controlled circuits to achieve all kinds of control functions.
It adopts +5V supply with pin 40 as its supply pin. Pin 18 and pin 19 connect
externally with 12M crystal oscillator to provide working clock frequency for
itself. Pin 9 is its reset pin. When starting, +5V charges C106 via R100. The
voltage of two ends of capacitance cannot be mutated, thus B-pole of triode
V100 is low level, that is, V100 conduction gives a high-level reset signal to
CPU. When capacitance C106 finishes charge, V100 stops and then reset
finishes. The form of this reset circuit is to reset high level and keep low level.
When the machine is working, the static information of Power-on logo on
screen and Chinese characters are stored in CPU internal static memory.
N101, a status memory, can record the current working status of machine
when powering off and show the status when next time power on, avoiding
users to re-adjust. The sound field mode set by users is also stored in it and
can be called when necessary.
2.4.2 Detect input signal and automatically search circuit
DISPLAY signal from volume board is sent to N103A to amplify and limit level,
and then sent to inverse end of voltage comparator N103B after capacitance
coupling. It inputs from pin 7 of N103B and then is sent to pin 16 of CPU via
VD103, V101, R109 and R107. When N103B inputs a high level, VD103 is in
reverse cut-off status, B-pole of switch tube V101 is high level and is in
conducting status, then gets an about +5V high level (signal input) to CPU after
VD101’s stabilization and stop searching. When the output end of N103B
outputs a low level, VD103 is in conducting status, B-pole of switching tube
V101 is low level and is in cut-off status, and then CPU detects the low level
(no signal input). Its working principles are as follows:
① After starting up, under CPU internal program’s control, a data signal is
outputted via pin 23 to M62446, and then M62446 scans each input port of
N101, N102 and N103 by emitting high and low levels. When the input ports
have no signal input, it automatically becomes standby status. When any of
ports has signal input, channel paths of input N101, N102 and N103 has A/C
signal which is amplified and limited level by N108B and N103A of CPU board,
then compares with pin 5 of N103B and gets plus-minus level close to supply
power. The co-phase voltage of N103B is about 0.1V. After the direct current
voltage is over 0.1V, the output end of N103B outputs low level is close to
negative-power voltage, VD103 positive-bias conducts, switch tube V101
(S9014) stops, emitter outputs a low level to pin 16 of CPU which by controlling
IC M62446 makes search level lock on the port through which signal inputs, to
enter normal play.
② When pressing “SEARCH” button on the remote controller, it is
converted from optical signal to electric signal by the remote control receiver of
panel. Pin 14 of CPU emits a high level to conduct V102 and search according
to the same previous process.

Automatic spectrum gain adjustment circuit: To avoid two situations that
spectrum display amplitude is too low when input signal is too weak or
spectrum display is in full screen when input signal is too strong, AV250T sets
automatic spectrum gain adjustment circuit, using a single-track
one-from-eight electronic analog switch, its true value diagram is as follows:

Its main working principle is to change the value of inverse ground resistance
of transmittal N104 to change the transmittal gain multiple. Let’s see the
detailed work of the whole circuit. We’ve referred that spectrum analysis signal
source (DISPLAY) is sent to the co-phase input end of transmittal N105C to
amplify. Its amplification factor is determined by the value of the resistance
connecting with the electronic switch of its inverse end N104. When the main
volume is large, CPU will automatically increase the value of ground resistance
and decrease the amplification factor; when the main volume is small, CPU will
automatically decrease the value of ground resistance and increase the
amplification factor.
Amplitude sampling circuit: signal amplified by N105C is sent via C115
coupling to seven band-pass filters composed of transmittals. By setting its
capacity of feedback capacitance, its frequency-band range can be determined.
The frequency value of superscript of the output points is the central
frequency-point of the frequency band. The output end of each band-pass filter
is connected with a half-wave rectifier circuit. The amplified A/C signal is
rectified to direct current. The circuit is mainly to achieve frequency-point
sample. It can display the amplitude of all frequency-points of the whole sound
signal via direct-current voltage. If the low frequency of sound signal is stronger,
the current voltage of output end of 35HZ and 100HZ band-pass filter is higher.
When high frequency is stronger, the current voltage of 10K and 16K
band-pass filter is higher. The output ends of the seven band-pass filter are
connected with the seven input ends of electronic switch N108 (CD4051).
These electronic switches will quickly circularly-switch among frequency points
(referring to previous true value diagram). Pin 3 output end of N108 will output
a string voltage value representing frequency point signal amplitude (see next
diagram).

A/D conversion and output circuit display (two situations):
1. When no signal input, pin 28 of CPU sends a high level to B-pole of V104.
The positive end of N102B is low voltage, the inverse end of N102B gets
partial voltage of R189 and R172, making N102B output a low level, that is,
triode V105 stops and C-pole of V105 will give a high level to pin 12 of CPU to
let CPU not conduct AD conversion (pin 6/7/8 of CPU are inactive and keep
high level).
2. When the machine has detected the signal (the inverse end of N102B has
a current voltage representing 35HZ signal amplitude), pin 28 of CPU is
converted into low level and +5V voltage charges for C137 via V103. When
reaching the voltage value of inverse end, the comparator converts and N102B
outputs high level. Once CPU receives low-level signal, it stops 35HZ level
gating and converts into next frequency point 100HZ. During conversion, pin
28 of CPU outputs an instant high level to conduct V104, leak the voltage
capacity of C137 and make the co-phase end of N102B restart to charge
100HZ from 0-level. When the charge of 100HZ finishes, the charge and
discharge of next frequency point begin, and such process occurs circularly
under the control of CPU. The charge time form 0-level to the occurrence of
output conversion represents the signal amplitude of current frequency
point—the larger the amplitude, the longer the time and the amplitude
displaying in screen is higher; the smaller the amplitude, the shorter the time
and the amplitude displaying in screen is lower. Digital pulse outputted from
N102B output end is added by V105’s inverse to pin 12 of CPU which handle it
and output to panel to display dynamic frequency in screen. The display of
original frequency points is sequential. However, the above circular process is
extremely quick, thus, what we see in screen is the progress of the whole
spectrum displaying synchronously.
Section Five Panel control and display circuit
The panel control and display circuit of AV110 adopts the special IC 101
(PT6311), whose external buttons of pin 10/11/12/13 scan buttons matrix. After
receiving the control command of users to the machine, processing is done
inside and then outputted by two ways: one way is sent to display screen to
display the working status; and the other way is transmitted to CPU through pin
5/6/8/9 to ask for performing and finishing the corresponding control function.
N102 is remote control receiver, which transforms the received infrared remote
control signal into electronic signal and then send it to pin 13 of CPU so as to
complete remote control function.
Section Six Power amplifier board

L channel signal is sent to pole B of differential amplifying stage V102 after
being coupled by R101, R103 and C101; V102 and V103 compose single
ended input/output differential amplifying circuit. Sound signal outputs from
pole C of V102 to pole B of voltage amplifying stage V105, and then outputs to
composite power amplifying stage after voltage amplifying. V104, V107,
VD102 and VD103 compose mirror image constant source circuit. VD102,
VD103 provide V104, V107 with constant base electrode current. Emitter
resistor of V104 determines working current of differential amplifying stage;
and emitter resistor of V107 determines working current of voltage amplifying
stage. V132 and V112 compose multiple unit tube amplifying to supply strong
current amplifying capacity for final stage of power amplifier, which composes
waveform positive half cycle amplifying. V133 and V113 compose waveform
negative half cycle amplifying and the circuit structure is the same with the
above. The function of temperature compensation tube V106 in circuit has two:
it is the base bias of geminate transistors firstly and its working state
determines the static working current of composite power amplifying stage,
that is, through adjusting the gating degree of V106, we may set the static
working point of composite power amplifying stage. The usual means is to
change the base electrode resistor of V107; it may also automatically adjust
the working state of composite power amplifying stage after the temperature
increases, with the adjustment process shown as follows:
Total current of output stage = working current + leakage current
When temperature increases, the increase of leakage current leads to drift
of static working point, and meanwhile leakage current of V106 increases. The
decrease of Uce makes the bias current of output stage decrease, the working
state change and the working current of back stage decrease to achieve the
function of temperature compensation.
Introduce voltage negative feedback into power amplifier circuit of AV250T,
composed of R121, R109, C105, which is capable of stabilizing static working
point of differential stage. AV250T adopts direct output means and R111, C116
connected to output terminal compose Joubert Network, capable of avoiding
high frequency self-excitation caused by the AC inductive reactance of
speakers voice coil.
Mote control: when pressing MUTE button on remote controller, a mute
signal, achieved through signal photoelectric conversion performed by remote
control receiver, is sent to CPU, and then a high level mute order is outputted
from pin 35, 36 of CPU to make V115, V101 and V116 on, left/right channel
signal has short circuit to ground to fulfill mute control function.
C, SR, SL power amplifying circuit: compared with the former models,
the three channels of AV250T adopt special power amplifiers LM1876 and IC
LM1875. As for LM1876, it has 15 pins in all, in which pin 2, 15, 4 are its
positive/negative power pin; and pin 7, 8, 12, 13 are its in-phase or reverse
input terminal. The rated output power of each channel of this power IC may be
up to 20W, with auto mute function when power on; as for 1875, it has 5 pins in
all. It is a good performance power amplifying IC, with very simple application
circuit and 15W power output in rated state. Pin 5 and 3 are positive and
negative power supply pin.
Section Seven Power board
Power board supplies working voltage required by each unit circuit and
over-current/over-voltage protection unit. Protection unit circuit is emphasized
here.
The protection means of L, R, and C channel is fulfilled through
disconnecting relay Y100 when starting up so as to disconnect the output. SR
and SL channel achieves protection function through mute. AV250T is with
power-on protection, central point over-voltage-over-current protection and
standby protection.
1. Power-on delay attracting protection circuit:
The working of circuit is unstable when power on and the generated
percussive current does great harm to speaker and power amplifying circuit, so
delay attracting protection circuit is set. This circuit is divided into two steps:
1) C, L, R. The working process is: a 22V voltage is achieved after AC
outputted by transformer being rectified and filtered by VD113, C110, and
then charges C115 through R108 to make VD111 struck through reversely
and make V105 and V104 in-phase on to finally make Y100 attract to reach
delay effect.
2) Surround left and right channels perform anti-percussion protection when
power on: after machine system resets, pin 33 of CPU outputs a high level
to pin 9, 14 of LM1876 through R164 to make LM1876 output mute. After
delay start-up of machine succeeds, pin 33 of CPU converses to low level
immediately and outputs normally through SL/SR channel.
2. Central point over-voltage protection:
An over-voltage sampling resistor is connected to the output terminal of
each channel. L channel is R116, R channel is R117, C is R118, SR and SL
channels are R119 and R120 respectively. Only when one channel’s central
point voltage is above +3.5V or below -3.5V, V101 or V102 is on to make their
C pole voltage decrease, then V103 on, relay disconnected and protection
circuit start up finally.

Over-current and short circuit protection:
An over-current sampling triode is connected to the output load resistor of
L/R channel. Sampling tube of L channel is V114 and load resistance is R126
and R127. The other three channels’ power amplifying IC is with over-current
protection inside. Only L channel appears over current, the pressure drop
produced on R126 and R127 will increase quickly. Once the pressure drop on
R129 is above 0.7V, V114 will be on, and V103 is also on. Finally relay
disconnects and protection circuit starts up.

The same, when R channel has over current, voltage on R159 will be above
0.7V to make V129 on, and then V103 on. Finally relay disconnects to reach
the purpose of protecting speaker.
4. Standby protection:
When standby time is up to 10 minutes and standby by force is needed,
PRC signal outputted from pin 34 of CPU is high level, which makes V100
saturated and on through VD108, R101 to make V103 on. Finally relay
disconnects to reach the result of standby and energy saving.
Section Eight Video board
Video board fulfills the functions of input, output and switch of the video, with
the schematic diagram shown as the following figure:
This switch function is realized through an electronic switch IC CD4051. When
high and low level of control signal A and B are changing, IC CD4051 switches
between VCD and DVD, and video signal is outputted by pin 3 VOUT.
