Carefully read and follow the manual for installation:
◆ Do not place the machine near heat sources such as radiators, heat registers or other products that produce
heat.
◆ In order to avoid being overheated please keep the unit's ventilation open.
◆ Do not expose this appliance to rain or moisture.
◆ Keep the amplifier in a certain distance so that it can be easily connected.
◆ Amplifier should install steadily and make sure all four feet are on the same level.
◆ Keep the amplifier over 15cm's distance to the surrounding walls.
Installation
Please make sure local voltage level is matched with
the input level of the amplifier, which indicates on the
rear panel. Too low or too high voltage may cause
problems or shorten the amplifier's life.

Balanced Connector:
1.This amplifier use XLR connectors that are
commonly used in professional application
for balanced connection.
2.There are two XLR wiring standards:

 European standard: pin 1=Ground,
Pin 2 = COLD, Pin 3 = HOT
American standard: pin 1=Ground,
Pin 2 = HOT, Pin 3 = COLD
3.This amplifier use American standard. When
connect to audio equipment with balanced output
wired in European, the playback signal might be in
reversed phase. We advise user to maintain the
phase of the system correctly.
Attention to Audio Connection:
1.Please refer to the manual of associated
equipment whenever necessary.
2.Do not connect the power cord until all
equipment are properly connected
3. “R”indicates the right channel; “L” indicates
left channel.
4.Please make sure all connectors are securely
installed. Bad connection might cause noise
and degrade in audio performance, or even
damaging your equipment.
5.Please do not tie the power cord, audio
interconnects, and speaker cable together or
run them in parallel because
this will produce adverse
effect on audio performance.
Note: Please make sure + and -, left and right are
connected properly.

Turn on the amplifier, the power indicator will be on and
the working indicator will keep flickering.
The working indicator will be on after 60 seconds. It
means that the amplifier is working normally. If the
working indicator is off, please turn off the power and
contact with our local agent or our company.
Select the right audio source channel, adjust the volume
to a certain position and then you can enjoy themusic
you prefer.
Turning On
Before turning on the amplifier please make sure all connections are right and power supply is stable.
1. When the audio system is under working state, don't
unplug the signal cable or speaker cables, or it will
cause damage to the amplifier and other equipments.
2. It should at least takes 2 minutes before you turn on the
power again, or it will cause damage to the vacuum
tubes.
