The ADK Z-12 is a multi-pattern tube microphone, derivative of the AKG classic with a similar name. The Z series from ADK, is their premium product line. All Z series microphones have been designed to emulate a handful of some of the most sought after vintage microphones from the ‘Golden Era” of recording. Handmade in the USA, using only the most refined materials and components, the Z-12 offers a boosted mid-frequency response and effervescent tops. Although the Z series of microphones have been designed to meet digital recording applications, ADK claim that the Z-12 and Z-251 are the most historically accurate microphones in their Z collection.
