WA-800 2 Channels 400W Class H Professional Power Amplifiers
High-power, high-efficiency output professional 2-channel 300W Class H amplifier, with its excellent quality and outstanding performance, is suitable for stage performance, concert, mobile performance, nightclub, disco and other sound reinforcement projects, which can match the sound system of major occasions.
The circuit automatically tests the input signal and will start the protection system if the abnormal standard is reached. It helps to avoid damage to the amplifier. Safety protection circuit to avoid over temperature, over current, short circuit and UHF damage.
This amplifier has a sturdy structure and advanced Class H circuitry, which has been rigorously tested before leaving the factory. Its dual-channel design allows for diverse connection options, while Class H technology ensures efficient power consumption and minimal heat dissipation.
1.Load resistance detection technology, using the music being played as a detection signal, real-time analysis of the output voltage and current, below 1.5 ohms will instantly start soft protection to limit the power crystal drive current, the fault disappears within 5 seconds to restore the output, this technology also solves the reliability problem of the bridge mode ultra-low frequency short circuit.
2.Separate detection of the output signal in the part of the signal voltage above 3KHz, 0.5 seconds accumulated beyond the high audio signal, the immediate start of the protection system to reduce the use of abnormalities in the process of damage to the tweeter driver.
3.Carefully selected materials with SMD technology and specially designed transformers make the machine smaller in size and larger in power output.
4.4 double DC variable speed fan heat dissipation, 45 degrees from the start of the control rotation so as to solve the sound of the whirring fan before singing in the private room. This machine has accurate over-temperature, over-current, short circuit, ultra-high frequency protection and anti-surge, switching impact protection function.
