Vipre: What is “variable impedance”

Altering the input impedance changes the load against which the microphone has to push – this dramatically alters the performance of any mic, from classic ribbons, vintage and modern condensers, even dynamic mics. All microphones will respond similarly in that the apparent proximity gets ‘closer’ when the impedance is lowered, but since you’re changing the load on the mic – you’re altering the performance of the microphone, not the preamplifier. A transformerless, balanced bridging input selection is also available. Bottom line: You haven’t heard your microphones until you’ve heard them loaded at different impedances. Anyone with even a modest mic selection can multiply the selections by using Vipre.
