CARDIOID CONDENSER
HANGING MICROPHONE
- Designed for suspension over choirs, in-
strumental groups and the theater stages.
- Superior off-axis rejection for maximum
gain before feedback.
- UniGuard™ RFI-shielding technology offers
outstanding rejection of radio frequency
interference (RFI).
- UniSteep® lter provides a steep low-
frequency attenuation to improve sound
pickup without affecting voice quality.
- Accepts interchangeable elements to per-
mit angle of acceptance 90° to 360°.
- Low-prole design with low-reectance n-
ish for minimum visibility.
- Available in two colors: black (U853A / U853R) and white (U853AW /
U853RW).
The U853A requires 11V to 52V DC phantom power or a 1.5V AA battery for
operation. A battery need not be in place for phantom power operation.
Alkaline batteries are recommended for longest life. Remove the battery dur-
ing long-term storage.
The U853R requires 11V to 52V phantom power operation only.
A uniform 120° angle of acceptance provides well-balanced audio pickup.
The microphone should be located forward of the front-most source, above
the rear-most source, and "aimed" between them (Fig.1). Increasing the
height of the mic above the sources will tend to equalize sound levels be-
tween them, but may also increase from the mic to the rear-most pickup
should be no more than twice the distance to the front source, to maintain
front-to-rear balance (Fig.1).
Width of pickup is approximately three times the distance to the closest per-
former. If additional mics are needed for wide sources, they should be posi-
tioned apart laterally at least three times the distance to front source, to avoid
phase cancellation (Fig.2).
To orient the microphone in the proper direction, twist the housing slightly in
its wire holder. (Clockwise rotation moves the microphone to the right; coun-
terclockwise rotation moves it to the left.)
Output from the power module's XLRM-type connector is low impedance
(Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground
(shield). Output phase is "Pin 2 hot" - positive acoustic pressure produces
positive voltage at Pin 2.
At integral 80 Hz high-pass UniSteep ® lter provides easy switching from a
at frequency response to a low-end roll-off. The roll-off position reduces the
pickup of low-frequency ambient noise (such as trafc, air-handling systems,
etc.), room reverberation and mechanically coupled vibrations.
Avoid leaving the microphone in the open sun or in areas where tempera-
tures exceed 43°C for extended periods. Extremely high humidity should also
be avoided.

定最前及最后的声源位置,而话筒应瞄准两者之间的中央(图
1),然后提升话筒高度,使前后声源趋向平衡;但却可能会增加
背景噪音声及回声,所以调校话筒时,应避免最后的声源距离长
于最前声源的两倍(图 )维持前后平衡。1
而与其他话筒的宽度距离,应以最前声源的大致三倍距离为最佳设
