PowerUS amplifiers come to market to bring to the consumer new cutting-edge technologies, thus strengthening the market for Brazilian amplifiers. They offer greater impedance options, innovative protections against installation errors, and also innovations in a range of operating range, where they operate from 7v to 16v, thus ensuring greater protection of the amplifier when the system runs out of power proper. It also features improvements in its construction, with robust components, thus being a more robust structure, providing a higher declared power delivery with 0.1% THD and calibration at 40Hz, including exclusive PowerUS functions as LIMITER.
