500W amplifier board, the input signal sensitivity is 1.5V rms, if the input signal voltage can't 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 aluminum alloy heat sink, nice heat dissipation.
The rated supplys voltage is dual supplys ±65V, and the voltage can work normally at ±58--±70V (over 70V, it will burn).
