Operational considerations dictate the use of passive splitting of microphones in most sound reinforcement applications. Modern microphones generally require a minimum load impedance of 1,000 ohms. Since mix desk input impedances rarely exceed 1,500 ohms, passive splitting utilizing 1:1 turns ratio transformers can seriously degrade microphone performance when used to drive two or more mix desks. Transformers designed to operate in stepdown mode solve this problem and offer other benefits.
