4-Channel D Class Amplifier 4 x 100W

A401 digital amplifier 4 x 100 watt

For those who want to upgrade their music system with a compact but powerful quality amplifier, car audio specialist AXTON has the 4-channel power amplifier A401 in the program: Minimal 10.5 cm wide and 4 cm high, this amplifier with 4 x 100 watts offers a lot of power in the smallest space. Thanks to the compact dimensions, the Class D amp can be flexibly installed in the car, motor home or caravan. The elegant, black aluminum housing is first-class processed and thoughtfully designed: Despite the compact dimensions, the massive heat sink conducts the heat specifically to the outside and thus ensures an optimal operating temperature throughout. The amplifier circuitry is designed with care, the design of the board layout is optimized for low distortion and equipped exclusively with selected components. Due to the sophisticated interaction of all components, this high-quality amplifier plays at the highest level: The A401 reproduces every piece of music with transparency, gripping dynamics and, above all, genuine joy of playing. The integrated electronic crossovers, each with 12 dB/oct. slope, are continuously adjustable from 40 – 400 Hz and can be switched as high-pass or low-pass filters. In addition, there are high-level inputs with auto-turn-on function for connection to original radios without RCA output – so the amplifier can be easily combined with factory-installed radios.
