Microphones For Broadcasters: Model 4115
The 4115 Broadcaster’s Noise Cancelling Ribbon Microphone is used
for close indoor talking situations where good quality broadcasting and
public address announcement speech is required to be reproduced in conditions
with high background noise present.
The 4115 has a proven reliable performance capability, being since its
introduction, used by broadcasters throughout the world.
The high degree of acoustic damping applied to the robust corrugated
aluminium ribbon ensures freedom from resonance and relative immunity
to handling noises and mechanical shocks.
There are many situations in which speech is partially or completely drowned
out by background noise; for example in aircraft, saw mills, shunting
yards, or power stations. Yet these are all places where it may be a matter
of life and death to have spoken instructions heard and obeyed without
a second's delay.
The 4115 is the microphone of choice for these circumstances.
There are two special versions for use in aircraft where, in addition
to the other requirements, it needs to be compatible with the aircraft's
electronics. These models are approved by the Civil Aviation Authority,
adn are also the choice of aircraft manufacturers and airlines.
