500W IRS2092S Digital Power Amplifier Board Mono Channel Class D Power Amp Board Module with Cooling Fan
Features:
500W power amplifier board, the input signal sensitivity is 1.5V rms, if the input signal voltage cant reach this value, recommended to add a preamplifier.
Premium amplifier board can help you amplify the weak signal from the audio source or pre-amplifier without changing the sound quality.
Support output short circuit protecting, output direct current bias protecting(speaker protecting) and over temperature protecting, safer to use.
Made of high-quality material, it has nice durability, with cooling fan and alloy heat sink, nice heat dissipation.
The rated power supplys voltage is dual power supplys ±65V, and the voltage can work normally at ±58--±70V (over 70V, it will burn).
