Warning The amplifier will be warm. Due to the high class A operating point used in the Electrocompaniet design, it is normal that the amplifier feels warm. Proper ventilation will be needed, and the amplifier should not be covered in. A good rule is to allow 1-2 inches of air sidewise, and 2-3 inches above the amplifier. Replacing a blown main fuse Diagram 2 Always remove the AC cord from the Inlet. The main fuse is located in a small drawer in the AC inlet of the unit.
Technical Specification AW 400 The following technical data were measured on randomized test objects and are typical data. All measurements are made with main voltage 120/240 V 50Hz / 60Hz. Main voltage 120 / 240 V. Clipping point of the amplifier is set to a level where total harmonic distortion (THD) is 0.2%. Output impedance (20-20kHz) ............................ Input impedance mono ....................................... Input sensitivity for rated output ........................... Max.
