CARDIOID CONDENSER ADAPTER-MOUNT
GOOSENECK MICROPHONE
- Designed for high-quality sound
reinforcement, professional
recording and broadcasting.
- Superior off-axis rejection for
maximum gain before feedback.
- UniGuard™ RFI-shielding
technology offers outstanding
rejection of radio frequency
interference (RFI).
- Easy-to-adjust, rugged, small-
dimeter, alternating gooseneck with
virtually no “memory” permits quick
positioning into desired shape.
- UniSteep® lter provides a steep
low-frequency attenuation to
improve sound pickup without
affecting voice quality.
- Accepts interchangeable elements
to permit angle of acceptance from
90° to 360°.
- Two-stage foam windscreen yields
dramatically improved resistance to
P-pops and other breath blasts.
- Direct mounts to any "-27 stand,
or to included threaded mounting
ange.
The U857A stands 305mm from the table or podium, it is also
available in a 421mm version as U857AL. The two models are
identical in all other respects.
The microphone 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 during long-term storage.
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® filter provides easy
switching from a at frequency response to a low-end roll-off.
The roll-off position reduces the microphone's sensitivity to
popping in close vocal use. It also reduces the pickup of low-
frequency ambient noise (such as trafc, air-handling systems,
etc.), room reverberation and mechanically coupled vibrations.
The microphone features a 3m permanently attached miniature
cable. It connects to provided AT8531 power module via
a special TA3F-type connector designed to optimize RFI
immunity.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 43°C for extended periods. Extremely
high humidity should also be avoided.
