The KM D digital output stage converts the signal from the capsule directly into a digital signal. The result is an AES/EBU signal with 24 bits and a large dynamic range. The integrated digital signal processor (DSP) permits remote control of the microphones, including the digital gain, pre-attenuation (6 dB, 12 dB or 18 dB) and low-cut filter (0 Hz, 40 Hz, 80 Hz or 160 Hz). An integrated peak limiter and compressor/limiter with additional de-esser function prevents any overloading of the audio signal.
The dimensions (diameter 22 mm, length 93 mm) of the analog and digital output stages are identical. As a result, all accessories can be used in combination with both output stages.
Upon request, a mechanical adapter can be supplied to adapt microphone capsules of the KM 100 system (AK series) to the KM A and KM D output stages.
The modular solution permits the microphone capsule to be separated from the output stage by a distance of up to 100 m. 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.
The capsule heads KK 183, KK 184 or KK 185, together with the appropriate output stage, are also available as a set, in which case they are referred to as KM 183 A, KM 183 D, etc.
