Atoll AM400 Evolution

The AM400 Evolution is the power amplifier of Atoll Electronique's 400 line. It uses four MOSFET pairs per channel, a 1050 VA toroidal transformer, shielded MKP coupling capacitors and a fully balanced XLR signal path, with internal wiring in silver-plated oxygen-free copper. The 10 mm front panel sits on a 2 mm steel chassis.
