HiFonics PLUTO I

The HiFonics PLUTO I is an exceptionally compact digital single-channel amplifier that delivers impressive output power despite its small size. As part of the PLUTO series, it combines modern Class D technology with high efficiency, extensive adjustment options, and high-quality craftsmanship.

Thanks to its advanced Class D circuitry, the PLUTO I achieves an efficiency of up to 90%. This allows the amplifier to drive high-powered subwoofers without taking up much installation space. Its compact design enables flexible integration even in tight spaces.

For use in modern vehicles, the amplifier features high-level inputs with integrated EPS® (Error Protection System). This system supports integration into vehicles with factory-installed radio diagnostic functions. The automatic power-on function also makes it easier to connect to factory-installed car radios, so that, depending on the vehicle, no additional adapters are required.

An adjustable subsonic filter, a low-pass filter, and a bass boost are available for customizing the bass response. The included bass level remote control allows you to conveniently adjust the subwoofer level from the driver's seat.

The HiFonics PLUTO I also impresses visually with its high-quality hairline-brushed heat sink, the precisely milled model name, and the recessed diamond-cut logo.
