Atoll IN 400 Evolution integrated amplifier

The reference integrated amplifier from ATOLL!

The IN 400, which has also received a lot of international attention, has once again exceeded its own expectations in its latest SE version. Not only have the best ingredients been used for the outside (such as the 10mm front panel or the ergonomic ventilation openings) for this amplifier, the interior is also bursting with performance. The double mono design guarantees the best channel separation, discrete, symmetrically constructed input and output stages ensure ATOLL-typical sound, a toroidal transformer with over 1kVA supplies the power amplifier, the gain of which (as well as all other functions of the IN400) can be easily adjusted using the IR remote control included in delivery.

The playback devices - you can also connect one via symmetrical XLR connections - and the volume are selected using a rotary knob. The display provides all important status information. Seamless integration into multi-channel systems has also been ensured: the BY-PASS input bypasses the preamplifier and allows the IN400 SE to be used as a pure stereo power amplifier.

The USB port (type B) is used to connect a computer. The integrated converter ensures that music from the hard drive can also be played in audiophile quality!
