About the AW400
The Electrocompaniet AW400 is a high-end, fully balanced solid-state monoblock power amplifier designed for demanding loudspeakers. It uses Electrocompaniet’s Floating Transformer Technology (FTT) power supply, a 650 VA transformer, and approximately 150,000 µF of power-supply reservoir capacitance. The amplifier is specified as stable down to 0.5 ohms and can deliver very high current, making it suitable for difficult speaker loads. It provides balanced XLR connectivity and dual speaker-terminal pairs for convenient connection. Note that published specifications vary slightly between older and current documentation; the figures below prioritize the current manufacturer-listed data.
