AB  - The transformer in a ribbon microphone interacts with the complex impedances of both the ribbon motor and the subsequent preamplifier. This paper presents a test setup that takes the influences of source and load impedances into account for predicting the amplitude and phase response of a specific ribbon microphone design in combination with different transformers. As a result, the effect of the transformer on the amplitude and phase response of the system can be simulated in good approximation by means of a generic low-impedance source. This allows for opti-mizing the ribbon/transformer/load circuit under laboratory conditions in order to achieve the desired microphone performance.
