KMR 81/82 i
Filter and attenuation KMR 81 i
The microphone has a 10dB
attenuation switch to prevent
the input of the following unit
from overloading.
A second switch activates a
200Hz high-pass filter. To-
ward the lower frequencies
the sensitivity of the micro-
phone is attenuated by ap-
proximately 15dB at 50 Hz.
The frequency range above
200Hz is unaffected.
Filter KMR 82 i
Between 2kHz and 15 kHz the KMR 82 has
a boost to compensate for HF transmission loss-
es in air when recording distant sound sources.
This may overemphasize any
sibilance if the microphone is
used close-up.
Therefore, a two-position slide
switch allows to select the
setting that is best for balanced
upper frequencies.
The KMR82 has a high-pass
filter to suppress subsonic in-
terference. The cutoff frequency may be raised
to 120 Hz (–3 dB) with a built-in two-position
slide switch.
Use on location
The shotgun microphones feature very high
output capability and a remarkably low self-
noise level.
Their low power consumption, light weight,
and low sensitivity to wind and handling
noise, make them ideal tools for news gather-
ing on location.
Small dimensions, together with a balanced
center of gravity, make handling easy without
any whiplash effect.
However, when on location and during strong
wind conditions, we recommend using an ad-
ditional wind screen (included as standard ac-
cessory). The wind screen is made of polyure-
thane foam and also serves as soft padding of
the microphone in its leather carrying case.
For mobile use a handle and an elastic suspen-
sion are available.
