D 58E/D 58E Black
Noise Cancelling Dynamic Microphone
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
