Description
Atoll AM400 : Mono Power Amplifier
During the development of the power amplifier AM400 Signature, the attention to detail led us to take into account all the parameters, to compare and listen to each component. The power stages have 8 MOS-FET transistors per channel which provide considerable energy, perfectly controlled thanks to carefully designed audio stages. The connecting cables between the motherboard and the loudspeaker outputs are made of pure copper, deoxygenated, silver plated with Teflon insulation. One of the best French manufacturers of audio cables makes these cables on demand. Similarly, filter capacitors, with low series resistance, are made to specifications by a leading specialist.
