Operating voltage is ±9V~±40V(±25V~±35V)RL=8Ω when the continuous output power reaches 68W (peak 135 W).
If the output power can reach 100W when connected to BLT, and its distortion is less than 0.03%, its internal design has a very perfect overconsumption protection circuit. I am also using the chip, its timbre is very sweet, mellow sound quality, quite a tube charm, suitable for playing more soft music. NS company also has LM1875, LM1876, LM4766 and other familiar chips, among which LM4766 is the latest, designed for dual channel, including overvoltage, undervoltage, overload, overtemperature and other protection circuits. Its output power is not less than 2×40W. The bass is deep and elastic, quite daring machine style
