The M 222 Tube Microphone Amplifier with NT 222 AC Power Supply from Schoeps has a circuit design that does not merely recycle technology from the sixties; rather it unites a first-quality tube with fully advanced circuitry. For example, the audio signal path is transformerless, and the overall specifications and performance are significantly improved. Any capsules of the Colette series can be used (including the BLM 03 Cg) as well as all active accessories such as the Active Low-CUT filter, KC active Colette cable, RC active extension tube, and GVC swivel capsule (all sold separately).
