The complete unit uses the dual differential complementary symmetrical push pull amplifying. FET (field effect
transistor) is put to good use for the track amplifier while the following stage adopts symmetric current negative
feedback circuit with wide frequency response range and low distortion.
For each channel, there are two stages for impulse, with four pairs of well-selected high-quality HI-FI high-power geminate
transistors as field effect tube output with wide dynamic range and strong controlling ability in low frequency.
The two high-power annual transformer supply power for the left and right channels, as well as preceding and following
stages independently with the following stage equipped with fast rectifying bridge and low impedance servo power
supply for the preceding stage.
The volume control adopts the blue large-size ALPS motor potentiometer and operated by the unique method of " analog
potentiometer by indirectly digital control " of our company which ensures the shortest delivering path and lower signal
distortion.
With VFD displaying screen, the whole screen looks superb and generous, as well as being equipped with a full functional
remote control board.
The complete unit is controlled by microcomputer with varied protecting functions to provide safety and convenient use.

Install Batteries
1. Use the tool remove the rear cover of the remote control unit.
2. Install the 2 batteries (AAA,R03).
3. Reinstall the rear cover of the remote control unit.
Battery Replacement
1. Install batteries observing the correct polarity,(+) and (-).
2. Do not use new and old batteries simultaneously.
3. Batteries with similar shapes may have different rated voltages Be sure
to use the correct batteries.
4. Remove batteries from the remote control unit if it will not be used for a
long period of time.
If you use the remote control unit to control the amplifier:
1.The remote control range is approximately 7 meters.
2.Pointing the remote control on an angle to the receiver, will shorten the
useful distance of the remote control.
!!
Incorrect use of batteries can cause corrosion or damage. The lower temperature,
the shorter battery life.

Machine can be used after finishing connecting to the machine and installing the remote control. Please refer to the
following if there is any question when using:
Signal input port
Use the affiliated cable to connect this port to the power supply, power supply voltage must be limitted in the range
indicated in the features of this instruction.
Terminal Post of Speaker
Connect the left and right channel and +/- indicator to the corresponding port post, speakers with the impedances
between 4 to16W are suitable for this machine.
Remote Control
Mute: Mute button, after this button pressed,"Vol---"will display on the screen and flicker, this will set the machine in
mute status. Repressing this button can release machine from mute status, Changing the volume can also free from
mute.
F1: temperature display button, after this button pressed once, current temperature will display for 1 seconds on the
screen with the measurement error within the range of ±2°C.
S-1 to Bal: signal source selection button, corresponding to the switch on of S-1 to S-4 and Bal.
Vol+/-: volume increase or reduce button, each time pressed, the volume will increase or decrease for one unit;
continuous pressing will bring the machine into fast increase or reduce status, which will change 10 units within one
second. Adjusting range is from 0 to 120.
Signal Selection
Press this button, S1 to Bal will be selected in repetition, at the same time, corresponding channel will display on the
screen.
Volume control
Tune clockwise to increase the volume, counter clockwise to reduce volume. The volume range is between 0 and 120
current volume will display when turned on. Each lattice circumrotated, will get a volume movement.(Notice: This
volume is not the real dB value of VOL, but only the digit denotation corresponding to the relative magnitude of
VOL).When adjusting the volume, current volume value displays; after the finishing of operating, signal source channel
will display again.
Power Switch
Press the power switch to put through the power supply; Signal input channel and current volume value will display
alternatively.
After starting, please connect the S- 1 at first,then S-2 or S-3. About a few seconds later, during which the volume
adjustment and sound source switch are allowed, the output relay switches on and the machine will enter working
order. System will enter normal work status.
Functions And Operating Instructions

Notice:
When the volume exceeds 8dB and display 'Error-1',the volume will be automatically decreased to 10dB;
When the volume bellows 80dB and display 'Error-1', the system will retain current volume;
If the display of 'Error' exceeds 5 times, the volume will become into zero and locking automatically;
If display 'Error',the volume will become zero automatically.
When the machine is in the heating protection and its temperature is between 55 centigrade and 70centigrade, please
restart the machine and it can work again then.
Intelligentized Protection
If short circuit, direct current or overcurrent happens, micro computert will cut off the input and output,and display "Error-1"
after removal failure, it will regularly work again.
If there is trouble in the volume control rheostat, it will display "Error-2" and cut off the input and output in that case, the
machine is in the beyond automatic recovery. After removal failure, please restart machine,then it will regularly work again.
When radiator temperature reaches 70°C, machine will close output signals for high temperature protection, current
temperaturevalue will flick and display on the screen; when the temperature fall below 55°C, machine will restore to normal
work status.
