Utilizing Earthworks Near-perfect Polar Response
Near-perfect Polar Response
Conventional cardioid microphones typically have poor polar response. They
will have a relatively uniform (i.e. flat) frequency response at the front of the
microphone (on-axis or 0 degrees), meaning they will uniformly reproduce high
frequencies, mid frequencies and low frequencies with a uniform level. However,
if you move to either side of the microphone (90 or 270 degrees) there will be
a dramatic loss in high frequency response. Perhaps the most telling demonstra-
tion of this is attempting to place three singers on a single conventional cardioid
microphone (one at the front and the other two singers on the sides). The singers
on the sides of the microphone will sound muddled and undefined due to the
loss of high frequencies at the sides of the microphone (off-axis). In figure 1a
you will see a perfect cardioid polar pattern which will pick up all frequencies
uniformly at the front and the sides of the microphone. Figure 1b shows the polar
response of a typical conventional cardioid microphone. Notice the severe loss
of high frequencies at the sides of the microphone. Figure 1c is the near-perfect
polar response of an Earthworks microphone. The Earthworks microphone has a
uniform frequency response at the sides of the microphone that is within 3db of
the on-axis response at any frequency.
The Earthworks cardioid microphone will pick up sounds with nearly the same
fidelity at the front and the sides of the microphone. This is a remarkable technical
achievement and one that will provide incredible results for you.
