The MMA-130 is a mono class D mixing amplifier with 30 W (8 Ω). The device has been developed in-house according to the specifications of a globally operating crane manufacturer and thus is perfectly matched to the application in the crane operator's cabin. The MMA-130 is used for the crane operator's announcements made to people within the pivoting range of the crane.
The compact dimensions of the amplifier which are matched to the dimensions of a standard slot in a motor vehicle and the voltage supply of DC 12-24 V allow for a wide range of additional applications.
The temperature range from -25 °C to +50 °C required for the area of application can easily be realised due to the selected components.
