Features
● High-inverter energy-saving switching power supply, ultra-high-performance Class D low-power digital power amplifier.
● Black high-grade 1U aluminum alloy pane
● l ultra-thin chassis structure design, small cabinet space occupation, good heat dissipation.
● The panel has independent LED lights for signal, protection, peak clipping, output signal, green-orange indication and power input blue indication.
● Complete protection functions such as short circuit, overload, high temperature, peak clipping and DC.
● Built-in low-cut compressor effectively filters out useless music signals in the frequency range of 20HZ-20KHZ; more stable and reliable, with clearer sound quality.
● With single balanced/unbalanced audio signal input, single channel rated power 500W.
● With independent input gain control signal amplitude adjustment and compensation (-3dB -0db range adjustable VOL LEVEL).
● Constant voltage/constant resistance dual switchable impedance balanced output (100V, 8Ω).
● The channel with high-impedance filter can be switched by the DIP switch, so that the sound reinforcement output has no upper and lower limits, and the broadcast intermediate frequency is clearer and brighter.
● With automatic temperature control cooling fan, front suction and rear exhaust, forced air cooling. The cooling fan sucks air from the front and exhausts it from the back. Do not block the air intake and exhaust ports.
● XLR balanced input with output Phoenix terminal (+ -= 100V: S+=8Ω).
● The automatic standby function saves power consumption. When there is no audio signal input, the power amplifier circuit stops working and the power supply circuit continues to work, thereby saving power, reducing temperature rise and increasing product life. When there is a signal input, it automatically exits the energy-saving mode.

Q: What are the advantages of Class D Audio Amplifier compared to other types of amplifiers?
A: High efficiency: It can achieve high power conversion efficiency, reducing power consumption and heat generation.
Compact size: Due to its high efficiency, it requires less heat dissipation, allowing for smaller and more lightweight designs.
Low power dissipation: This results in less heat and lower cooling requirements, which can lead to longer component lifetimes and more reliable operation.
Q: What factors should be considered when choosing a Class D Audio Amplifier for a specific application?
A: Efficiency: Look for an amplifier with high efficiency to ensure energy savings.
Sound quality: Although the reference materials do not provide specific details on the impact of Class D Audio Amplifiers on audio quality for this application, it is still an important factor to consider.
Power requirements: Determine the power needed for the specific application to ensure the amplifier can meet the demands.
Q: How does the output filter in a Class D Audio Amplifier affect the sound quality?
A: The output filter affects the sound quality as follows: The output filter can change the sound quality of the sound, enhance the sound of certain frequencies, and weaken the sound of other frequencies. It can be used to eliminate noise, reduce distortion, enhance low and high frequencies, and improve bass. At the same time, the low-pass filter can filter out the high-frequency components of the rectangular wave.
