The Type A vacuum tube microphone system is an innovative and unique solution for virtually any recording need. Combining low noise and superb transient response along with a choice of nine different interchangeable capsules (The Redheads), you’ll quickly discover the Type A is a microphone system that will provide years of dependable service and amazing sounds. In an instant, you can change the bayonet-mount capsule for a stunning variety of sounds and pickup patterns without even shutting off the power! The transformerless Class A discrete amplifier circuit of the Type A is a thoroughly modern design with a nod to the classic circuits of yesterday.
Utilizing a single hand-selected ECC88 vacuum tube, you’ll hear musical detail and subtlety previously only heard in mics costing thousands more! The Type A includes a custom-built flight case, our high-definition tube mic cable, shockmount and the innovative PowerStream power supply, which not only insures ultra-stable performance but features our soft-start feature which maximizes tube life and minimizes startup time.
