The combination of the capsule KK 143 with the analog output stage KM A is only one of the numerous options within the modular
KM A/D small diaphragm microphone system. Eight different small diaphragm capsules (KK 120 up to KK 185) may be combined with either an analog output stage (KM A) or a digital AES 42 output stage (KM D). A comprehensive range of accessories ensures adaptability to the most diverse fields of application.
