Directional Mic.

Directional Microphone - Description

Our directional microphone helps you to find sources of noise easily and intuitively without any special knowledge.

As soon as you get close to the noise source with the gooseneck microphone, you will immediately hear the corresponding noise with the headphones.

Monitoring Probe AV11

  • Handheld monitoring probe
  • Measuring output
  • Adjustable Headphones output
  • Amplifier: 0 dB or +20 dB
  • Switchable octave filter
  • Switchable third octave filter
  • Display with backlight
  • Overload indication
  • Internal rechargeable accu
  • Robust aluminum cabinet

Technical - Description

The 1 channel monitor amplifier AV11 is a handheld, accu driven monitoring probe, which has been constructed mainly to monitor acoustic signals or to detect noise
sources with headphones.

AV11 offers you many possibilities to locate disturbance sources. It comes with a permanently mounted 120mm swan-neck and directional Microphone.

The measuring signal can be weighted with the switchable octave filter (9 frequencies) or third octave filter (25 frequencies).

So you can detect the exact frequencies
of the disturbance source.

Monitoring Probe Display

At the output socket you get a voltage proportional to the sound pressure independent of the amplification of
the headphone amplifier. So the instrument can be used as a front end for analyzers or similar instruments.

The AV11 has been constructed for mobile uses.

he sensors, which are available in three measurement ranges
(±2, ±5 and ±18 g) covering an extremely broad spectrum of measurement scenarios, come in a leather case containing calibration certificate, standard integrated 3-meter cable, magnetic base for mounting on magnetic surfaces, instruction manual, driver, and examples of programming in a Labview environment, which enables you to develop customized measurement applications.
The sensors can be used for a wide range of applications, thanks to the available application software and accessories.
