1 NOTES

High voltage inside the equipment. Do not open the cover. Ask for the help from the
professionals when need servicing.
Please do not expose the equipment in the rain or moisture.
Keep adequate ventilation, do not block the port.
Be sure the voltage of this equipment complies with the local industrial voltage.
Please put off the power plug if unused for a long time.
Please connect rated load. Never working under the overload for a long time.

Symbols:

The equilateral triangle with lightning bolt warns the user of dangerous voltage levels
localized within the cabinet.
The equilateral triangle with exclamatory mark means the important operation on the
user's manual.

2 FEATURES

UA series is the amplifier with big power and excellent performance. It can meet

different audio avenues.

1> Big power,dynamic energy;
2> Innovative heat sink structure and high quality heat sink fan assure reliable working for
a long time;
3> "loading impedance temperature-power-running voltage" can be controlled alternately,
Speed of Fan is automatic adjusted by temperature. When load is too low or temperature
is too high, the equipment can adjust the power supply and lower impedance of power,
which improves sound quality and protect the equipment better. The reliability will be
improved remarkably;
4> Low distortion;
5> High slew speed, outstanding sound quality and high transparent;
6> Low noise:S/N>108dB(A Weight);
7> 20Hz~20KHz <+0/-0.25 dB;wide frequency band;
8> Small dimension, 2U rack mounting.

9> UA2002,UA1332,UA662,UA332 are specially designed for low loading imedance,and
can work for a long time under 2 .
