The Neumann KM A Analogue output stage, equipped with P48 phantom power, features a built-in 10 dB pre-attenuation switch, enabling the microphones to handle up to 152 dB, depending on the capsule type.
The Neumann KM A analogue and KM D digital output stages share identical dimensions, with a diameter of 22 mm and a length of 93 mm. Consequently, all accessories are compatible with both output stages. A mechanical adapter, the AR 100 KA, is available upon request to use KM 100 system microphone capsules (AK series) with both the KM A and KM D output stages.
