Features:
500W 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 board can help you the weak signal from the audio source or pre- without changing the sound quality.
Support output short circuit protecting, output direct current bias protecting(speaker protecting) and over 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 supplys voltage is dual supplys ±65V, and the voltage can work normally at ±58--±70V (over 70V, it will burn).
Specifications:
Material: + Alloy
Supplys Voltage: Dual Direct Current Supplys ±58---±70V
Rated Output : 500W (±65V supplys 4 ohm load, distortion 10%)
Efficiency: ≥90%
Signal to Noise Ratio: 90dB
