The Evolution 403e is the most powerful three channel amplifier available today. Housed in the same chassis as the Evolution 900e, the Evolution 403e is the perfect choice for Left, Centre, and Right channel amplification in a high-performance home theater. The Evolution 403e is equipped with two 3,000 VA transformers and 188,000 microF. This power source is the backbone for the output of the Evolution 403e. With this foundation, the Evolution 403e delivers 400 watts into 8 Ohms and 800 watts into 4 Ohms with three channels driven simultaneously. The FTC mandates that power ratings are quoted using a 1,000 Hz sine wave into a fixed 8 Ohm resistor with final power specification stated at 1% distortion.
