1) Which of these three are high & low impedence, SM58, 520DX Green Bullit, and Beta 58?
2) What advantages or disadvantages does Beta have over regular SM58?
3) Will an SM58 work in both low and high impedence systems, for example both ampliphers and PAs?
1) SM 58 = low; 520 DX = high; Beta 58 = low.
3) The SM58 will work into a high impedance system IF the A95UF transformer is added to the equipment end of the mic cable.
