One of the main innovations was the High Current mode selectable on the back panel, previously used only in the flagship T+A M 40 HV monoblock amplifier. In this mode, the output stage is constantly energized, so that the actual operating range in Class A, depending on the characteristics of the connected acoustics, can exceed 75 watts. For systems requiring maximum power, the High Power mode has been retained, in which the amplifier is capable of developing up to 500 watts in class AB.
