Neumann KM A Miniature Microphones System
The Neumann KM A Miniature Microphones System is a flexible miniature microphone system. A comprehensive selection of accessories permits adaptation to a wide range of requirements. Eight different capsules are available which are compatible to the digital miniature microphone system KM D.
The Neumann KM A / KM D Miniature Microphone System
The modular KM A / KM D miniature 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.
KM A/KM D Output Stage
The Neumann KM A Miniature Microphones System analog output stage with P48 phantom power has a switch for pre attenuation of 10 dB. The microphones can thus handle levels of up to 152 dB (depending on the capsule type). 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 Neumann KM A Miniature Microphones System and KM D output stages.
The modular solution permits the Neumann KM A Miniature Microphones System 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.
Application Hints:
KK 120 KM D
- MS Stereo microphone, in combination with the KM 184 D
- Two crossed KK 120s in Blumlein technique
- Inconspicuous spot microphone with optimum attenuation of lateral sound sources
- Single microphone for two speakers facing each other
KK 131 KM D
- For close miking of instruments when there is no need to attenuate extra neous noise, and in a balanced acoustic environment to record acoustic guitar, wind instruments, strings, percussion, and drums
- Flat frequency response for close miking, spot mic
KK 133 KM D = KM 133 D
- Its special acoustic properties make this an ideal mic for most classical recordings
Main mic, especially for capturing room acoustics - A superb AB stereo pair for perfect balance of direct and reverberant sound
- Decca tree, setup with three microphones
- Spot mic for piano, wind instruments, organ, choir
KK 143 KM D
- Polar response characteristic acts more like an omni. Therefore, it is an ideal tool to record larger instrument ensembles
- As AB stereo pair, especially in rooms with less than ideal acoustics
- As spot mic for strings, wind instruments, percussion, and Leslie speakers
- Acts very neutral when used close up to bass instruments, such as double bass, bass amps, guitar amps
KK 145 KM D
- It naturally compensates for proximity effect
- Very neutral tonal balance during close miking of speech, as in TV, movie and video, PA
- Acts very neutral when used close up to bass instruments, such as double bass, bass amps, guitar amps, leslie speakers, toms
KK 183 KM D = KM 183 D
- For close miking of instruments when there is no need to attenuate extraneous noise, and in a balanced acoustic environment to record acoustic guitar, wind instruments, strings, percussion, drums
- Ideal as AB stereo pair because of the flat frequency response in the diffuse sound field
- Main mic, especially for capturing room acoustics
- For stereo recordings with a baffle plate
- Spot mic for piano, wind instruments, organ, choir
KK 184 KM D = KM 184 D
- For universal use, especially for recording situations when it is necessary to attenuate off axis sound (mainly from the rear) from other nearby instruments.
- As XY and ORTF stereo pair
- Broadcasting mic for announcers
- Spot mic and overhead
- Close miking of strings, wind instruments, percussion, piano, Leslie speakers and guitar amps
KK 185 KM D = KM 185 D
- Especially for recording situations when it is necessary to attenuate off axis (lateral and rear) sound from other nearby instruments.
- As XY stereo pair
- Overhead, toms
- In situations that are susceptible to acoustic feedback
- To attenuate unwanted sound of nearby instruments
- Recording of speech, as in TV, movie and video productions, PA systems
- Produces especially warm and bass supporting sound for artists who perform in proximity effect range
