905R
Line-cardioid Condenser Mini-gooseneck Microphone
Description
The Astatic 905R is a line-cardioid, quick-mount, miniature-
gooseneck condenser microphone designed for speech and vocal
pick-up. The line-cardioid polar pattern (Locus
TM
technology)
is engineered to attenuate unwanted sources outside of the
+/- 45 degree acceptance angle while effectively “zeroing-in”
on the desired speaker. Astatic’s Locus
TM
technology provides a
signifi cant improvement over other line-cardioid microphones
due to diaphragm size and low-noise electronics.
The 905R is appropriate for applications such as boardrooms,
courtrooms, house of worship and anywhere a gooseneck
microphone with optimal distance pick-up is needed. Locus
TM
technology allows the installer to use the 905R in place of
longer miniature-gooseneck microphones without sacrifi cing
performance. It is the perfect solution for the user who prefers
not to be distracted by an obtrusive transducer.
The 905R is a commercial-grade microphone featuring an
all-metal body. The 8mm steel memory-fl ex gooseneck
and ultra-quiet movement provide for worry-free, life-long
microphone operation. Special attention has been taken to
design the 905R with improved RF immunity to greatly reduce
susceptibility to radio interference from GSM based cell phones,
PDA/cell phones with walkie-talkie capability and other similar
devices.

1. Mark the center of the mounting location. Be sure to check
the underside of the surface for obstructions.
2. Using a 7/8" hole saw or drill bit, cut the centered hole
for the cable and bottom of the mount to pass through
the
surface.
3. Fit the mount into the hole so that the fl ange sits fl at on
the surface. Mark the three mounting holes around the fl ange.
4. Remove the mount from the hole and pre-drill the marked
mounting holes for screws appropriate for the installation.
5. Make all fi nal audio connections to the XLR connector.
