Functional characteristics
1. Industrial modeling solid iron panel, stamping concave appearance modeling, light body, easy to transport.
2. Boot soft start, to prevent the power grid to absorb large current, interference with other electrical equipment.
3. Intelligent control forced heat dissipation design, fan noise is small, stepless wind speed, intelligent constant temperature, high heat dissipation efficiency.
4. Two-channel power amplifier has three input sensitivity options, easily accept a wide range of signal source input.
5. Perfect and reliable safety protection measures and working status indicators (short circuit, overload, DC and overheating protection), so that users can use at ease.
6. Intelligent clipper limiter, control power module and speaker system work within the safe range.
7. Standard XLR+TRS1/4 "composite input interface, simple interface is more convenient for different user needs.
8. High quality transformer and low resistance and large capacity electrolytic filter, to ensure that large dynamic work can cope with freely.
9. Adapt to different occasions, optional stereo or bridge working mode.
10. Input grounding pin grounding and suspension control.

FAQ
Q
High noise level
A
It should be determined first whether the noise comes from the front stage or the back stage circuit. The signal connection plugs of the front and rear stages can be removed. If the noise significantly decreases, it indicates that the fault is in the front stage circuit;
Q
When the machine has no output or when the output volume is high or low
A
After prolonged use of the machine, dust and usage environment can cause oxidation of the volume adjustment potentiometer,
Q
Cooling fan slow or stalled
A
Whether the heat dissipation fan of the power amplifier is working properly plays a crucial role in ensuring the operation of the machine. So when the fan speed is slow or not running, the power amplifier should not continue to be used,
