Anyone who is on the road in their truck for days or weeks also wants convincing sound in their vehicle: when listening to music while driving or watching videos during rest periods. Retrofitting an amplifier is a simple measure to enormously improve the performance and sound of factory systems or multimedia / navigation devices – without replacing the entire system. With the new AT-series, AXTON now has two compact amplifiers in its range that can be flexibly installed in trucks and provide power sound and a clearly audible sound upgrade. The AT-series seamlessly builds on the extraordinary performance of the AXTON A-series and is designed for trucks, truck-based motorhomes and other vehicles with a 24 V power supply. The new AXTON Class-D amplifiers perform at a very high level in terms of sound and technology. Inside the compact housings – they are only 10.5 cm wide and 4 cm high – the well-thought-out amplifier circuit ensures a sound with astonishing performance. These amps give every piece of music with transparency, thrilling dynamics and above all real joy of playing. The design of the circuit board layout is optimized for lowest distortion, encapsulated components ensure high immunity to interference. The AT401 four-channel amplifier is equipped with active crossovers and high-level inputs with auto-turn-on function.
