IRS2092S High-puissance 500W D-class HiFi Amplificateur Numérique Carte Finished Mono/super LM3886

Dual DC power supply range of ±45V to ±70V, with a recommended ±65V for optimal performance.
Rated sortie power of 500W at ±65V supply with a 4-ohm load and 1% distortion.
High efficiency of 90% or greater, ensuring minimal energy loss during operation.
Excellent signal-to-noise ratio of 90dB for transparent audio sortie.
Total harmonic distortion of 0.1% or less at 380W (±70V supply, 4-ohm haut-parleur) and 280W (±70V supply, 8-ohm haut-parleur), along with a frequency response range of 20Hz-20kHz.
1. Do not wire and touch the audio entrée by hand without power on. 2. The sortie should not be no-load, connect the haut-parleur and do not short circuit. 3. To be used under the specified load and voltage. According to the power formula P=U*U/R=voltage*voltage/load, it can be seen that the power is determined by the voltage and load. The higher the voltage and the smaller the load, the greater the power. The voltage range of the carte refers to the voltage within this range. The carte can work normally, not all voltages and load power are as high as the marked power sortie. Main technical parameters: 7. haut-parleur: 4-8Ω 8. Tension magnification: 50 times 9.
