    Environment (domestic, light industrial). - the power supply connected to the wma-02 should be double insulated (class ii) or a selv type (selv = safety extra low voltage, typically a battery). - the wma-02 is a class iii product. Do not connect the amplifier to the mains safety earth. If this is do...

    100pf/m. The cables that are connected may well limit the maximum usable frequency. If output monitoring is required, it is recommended to connect a 10x oscilloscope probe to the output. A special bnc to probe tip connector is usually supplied with the probe (fig. 1). However, the user can choose a ...
