Add versatility to your Audio -Technica UniPoint
microphones with the following replacement
elements. Different pickup patterns are now
attainable with the same high-quality UniPoint
design via interchangeable elements.
These elements are screw-on replacements for
all AT851, AT853, AT857, AT871 and AT873R
UniPoint models.
AT853H - ELE
The hypercardioid element (the standard
supplied with the AT873R microphone) in-
creases directionality to 100
°
to provide better
gain- before-feedback and reduction of back-
ground noise.
AT853C - ELE
The cardioid element is the standard supplied
with the AT851, AT853, AT857 and AT871 micro-
phones. It features a 120
°
frontal pickup area.
AT853SC - ELE
Subcardioid element allows a wider 170
°
frontal
working area than a standard cardioid.

AT853O - ELE
Omnidirectional element allows operation in all
directions with a 360
°
pickup pattern.
Different combinations of the elements can be
used to obtain the desired results.
The illustrations below show the differing prop-
erties of the four pickup pattern types.
The distance factor, D, indicates the additional
pickup range available with directional elements.
The distance factor is the increase in working
distance that produces the same signal-to-noise
ratio as an omnidirectional element under the
same ambient conditions. For example, the s/n
ratio of a cardioid at 17 feet would be comparable
to that of an omnidirectional at 10 feet.
The acceptance angle indicates the pickup
width at which the sensitivity of the microphone
has dropped by 3 dB from the on-axis (front)
sensitivity.
