### Test of the supply current
By measuring the supply current I_SC, the general function of the individual amplifiers (High Power Amplifier ZHL-20W-13SW+) is to be tested. For this purpose, a multimeter (VOLTCRAFT MT-51, SN: 09126841) was inserted into the current path of the supply current I_SC. According to the amplifier's data sheet, the supply current I_SC is max. 2.8 A during proper operation (with fan). The values measured (Table 2) are within the tolerances.
