2 X 250Watt Class D Audio Amplifier Board - IRS2092(AA-AB32291)

Picture Showcase


Brief Introduction:

  • This 2 X 250Watt Class D Audio Amplifier Board - IRS2092 is a state-of-the-art dual channel Class-D audio amplifier which integrates IRS2092 Class D audio driver IC, along with IR’s digital audio dual MOSFETs. This amplifier is capable of delivering dual-channel amplification with each channel up to 250W. High quality and high performance components are used making this amplifier high-quality amplifier. Powered by ± 55V to ± 65V supply, it can be used in many ampplications like Background Music Systems. It also features thermal protection, Over-current protection, Over-voltage protection, Under-voltage protection and DC-protection. In addition, on-board heat sink ensures excellent heat dissipation.
  • This is an exceptionally well designed amplifier, with low distortion, good S/N ratio, low consumption and full protection. Having all these almost ideal characteristics this amplifier is likely to become the basic building block of your future high fidelity system, or it can also become the element that will upgrade your existing system.
  • Please pay attention:This amplifier board needs dual power supplies and it doesn't support BTL mode.
