Neumann KK 131 nx

The KK 131 is a free-field equalized pressure transducer. The sensitivity in the free sound field is flat up to 20 kHz. In the diffuse sound field, there is a roll-off above 5 kHz.

acoustical operating principle: pressure transducer directional pattern: omni free-field equalized frequency range: 20 Hz up to 20 kHz sensitivity at 1 kHz into 1 kohm: 12 mV/Pa rated Impedance: 50 ohms rated load impedance: 1000 ohms equivalent noise level, CCIR: 24 dB equivalent noise level, A-weighted: 13 dB-A maximum SPL for THD 0.5%: 140 dB maximum SPL for THD 0.5% with preattenuation: 150 dB signal-to-noise ratio, CCIR (re. 94 dB SPL): 70 dB signal-to-noise ratio, A-weighted (re. 94 dB SPL): 81 dB supply voltage (P48, IEC 61938): 48 V current consumption (P48, IEC 61938): max. 3.5 mA matching connector: XLR 3 F weight (output stage): 70 g weight (capsule only): 11 g diameter: 22 mm length (capsule only): 18 mm length (microphone): 108 mm

The combination of the capsule KK 131 with the analog output stage KM A is only one of the numerous options within the modular Neumann 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.

FEATURES:

  • directional characteristic: omni (free-field equalized)
  • part of the modular microphone system KM A/D
  • comprehensive range of accessories
