The modular KM A microphone system is a further development of the successful KM 100 series. The newly developed passive capsule design is available with 8 different directional characteristics, and can be combined modularly as desired with an analog (KM A) or digital (KM D) output stage in accordance with the AES 42 standard.

The new, considerably smaller microphone capsules and an extensive program of accessories permit excellent adaptation of the microphone system to a wide range of applications.

Through the use of the most up-to-date electronic components the system offers many electroacoustic and operational advantages, such as lower self-noise, a wider dynamic range and very high immunity to electromagnetic interference. The acoustics of the capsules were taken from the proven KM 100 system.

overview of microphone capsules compatible with the KM A output stage:

• KK 120: figure-of-eight
• KK 131: omni (free-field equalized pressure transducer)
• KK 133: omni (diffuse-field equalized pressure transducer, titanium diaphragm capsule with exceptional acoustic properties)
• KK 183: omni (diffuse-field equalized pressure transducer)
• KK 143: wide-angle cardioid
• KK 145: cardioid with acoustic bass roll-off in free field
• KK 184: cardioid
• KK 185: hyper-cardioid

The KM A analog output stage with P48 phantom power has a switch for pre-attenuation of 10dB. The microphones can thus handle levels of up to 152dB (depending on the capsule type).

The dimensions (diameter 22mm, length 93mm) of the analog and digital output stages are identical. As a result, all accessories can be used in combination with both output stages.

The modular solution permits the microphone capsule to be separated from the output stage by a distance of up to 100m. The LC 4 microphone cable with a length of 5 or 10 meters is available as a standard solution. Alternatively, capsule extensions of different lengths, swivel joints and stand mounts, etc., can be used for a flexible system setup.
