Description

By means of the NC-111 Ambient Noise Controller, the ratio of the desired signal (speech or background music) to unwanted extraneous signal (unwanted noise) can be considerably improved, e.g. in airports, railway stations, hotels, etc.

Features

  • The device is supplied with the ND-011 Ambient Noise Detector, which is equipped with an XLR or jack socket for connection of an electret or dynamic sense microphone.
  • An adjustable reference level is used to set a lower limiter to the output level. A level that is below the reference level is not accepted.
  • Filter performance (-width) is adjustable.
  • The LED chain (-9 dB to +18 dB) on the front panel indicates the output level. There is also a clipping LED.
  • The device includes an adjustable measuring band-pass filter with a range of 30 Hz to 15 kHz and a bypass switch for disabling the NC-111.
  • The noise detector has a phantom power switching option and can be connected by means of an AF cable with a maximum length of 500 m.
