Atoll AM300 EVO

The AM300 EVO power block has been specially designed to meet demanding amplification needs, offering improved audio performance and remarkable thermal protection. It has new RCA connectors. In addition, it can be bridged to a mono block via an external switch and is equipped as standard with a 12V Trigger input (direct ignition in connection with a preamp). 8 mm brushed, micro-blasted, and anodised aluminium front panel with high-precision engraving. 2 mm steel chassis. Two 440 VA toroidal transformers + one 5 VA (control logic). High-quality, shielded MKP coupling capacitors. Custom-made printed circuit board with nickel/gold finish. Purely balanced XLR signal processing. Bipolar transistor and LED current sources ensure perfect voltage stability. Reworked audio stages to make the device immune to capacitive loads. Improved signal-to-noise ratio. Thermal protection. High-quality RCA input/output connectors, screwed to the chassis. Tellurium copper speaker outputs. 12V Trigger input.
