12 C 4500 BC
Description
This version of the C 4000 has been specifically designed for use in radio
newsrooms.
This large-diaphragm condenser microphone has been designed on the basis
of experience AKG and its customers have gained worldwide over decades
using AKG’s well-known studio microphones. The
C 4500 BC uses advanced,
reliable components to meet the highest professional demands and withstand
even long-time, tough handling in the studio.
The C 4500 BC provides the following features :
The diaphragm is made of a plastic foil that is gold-sputtered on one side and
prevents local shorts to the back electrode even at extremely high sound
pressure levels.
A
switchable preattenuation pad
allows you to increase the maximum SPL
capability of your C 4500 BC by 20 dB for distortion-free close-in recordings.
Many mixing console input stages use small transformers that are susceptible
to overload, particularly at low frequencies. The
C
4500 BC’s pad prevents
such overload.
A bass cut filter that is switchable on the microphone body reduces low-end
distortion due to uncontrolled rumble or wind noise even further. The filter has
a 6 dB/octave slope starting at 120 Hz.
The
all-metal die-cast body
shields the microphone very effectively against
RF interference when using it near radio transmitters or together with wireless
microphones or other communication systems.
A dual wire-mesh grille and other design features provide effective protection
against electrostatic and electromagnetic interference from the various
monitors used in advanced or automatically controlled radio studios.
In addition to high sound level capability and minimum distortion as well as
temperature and humidity resistant construction, the microphone features a
cardioid polar pattern specifically optimized for the kind of close-up usage
typical of broadcast work.
