AKG D 58E Specifications

Description
This noise cancelling microphone is a gradient model
which has its diaphragm assembly tuned to a mid-range
frequency. As such, the D 58 E will give fairly flat response to
near sources (due to proximity effect rise at low frequencies)
while exhibiting a strong mid frequency and bass roll-off for
sounds arriving from a distance. It is necessary that the
microphone be addressed at distances no greater than about
2 inches (5 cm) for the speaker's voice to be clear and
natural. The microphone is quite small and can thus be used
at very short working distances without disturbing the user.
In addition, the close-in response of the microphone
exhibits a broad rise in the mid-range between 1 and 5 kHz
in order to improve speech intelligibility when the microphone
is used in noisy environments. The D 58 E is rugged,
lightweight, and operates well over a wide range of both
temperature and humidity.
The Model D 58 E Black is the same as the D 58 E except
for a black finish.
