            Digital technology

            Digital technology

            The X-Power series amplifiers use digital technology similar to the PDX series, delivering high efficiency. In addition, such excellent audio performance is characterized by low distortion, high attenuation factor and high signal-to-noise ratio.

            Easily customizable to any system

            The amplifier has speaker level inputs that allow it to be connected to a factory-installed control unit that has no pre-amplifier outputs. This way you can enhance the original system with more power and better speakers.speaker level inputs

            Remote sensing

            The remote monitoring function automatically turns on the power when the amplifier detects an incoming audio signal. No separate long distance is required.

            Smaller outside dimension

            PDX digital technology means greater efficiency, so X-Power amplifiers are 29% more compact than previous models, making installation even more convenient.

            Smaller outside dimension

            Effective heat protection

            If the amplifier gets too hot, a thermal protection circuit applies, which reduces the output power by a few steps without interrupting the music. Surge and overcurrent protection is also provided.

            Bass Control Button (RUX-KNOB)

            Just add the RUX-KNOB (sold separately) and you have full control of the bass from the dashboard. With this driver, you can control multiple amplifiers through simple adapters with telephone wires.
