OPTIONAL ACCESSORIES
PLENHSEM3 brass plenum bell housing (patent pending). This brass housing is
specifically designed to provide a plenum seal when threaded on to the plenum
junction box. The bell housing is included with all Audix CAT 7 prepackaged
interface cables (see below for models), and may be purchased separately for bulk
cable runs.
CBLM3XLR breakout cable consisting of an RJ45 female to three XLR male
connectors. This cable is designed to be used in conjunction with Audix CAT 7
interface cable, keeping the shielded and balanced audio path intact when
connecting to the three mic level XLR inputs of a DSP Controller.
CBLM307 - Interface Cable 7 meters (23’)
CBLM310 - Interface Cable 10 meters (33’)
CBLM315 - Interface Cable 15 meters (49’)
CBLM320 - Interface Cable 20 meters (66’)
CBLM325 - Interface Cable 25 meters (82”)
Note: The Audix M3 also works with CAT 5 and CAT 6 cable, however, Audix recommends
using shielded cable.
8CAT7 Interface cable. Audix manufactures a high quality CAT 7 cable optimized for
balanced audio and cross talk elimination. The cable is LS0H (low smoke zero halogen)
and consists of four twisted pairs that are individually shielded, RJ45 male connectors
and a brass housing to further seal the cable at the plenum rated junction box. The
interface cable is available in prepackaged lengths or in bulk (see below for models).
CBLM330 - Interface Cable 30 meters (98”)
CBLM350 - Bulk cable. 50 meters (162’).
Use with brass plenum bell housing #6
for best results.
CBLM3100 - As above. 100 meters (325’)

INSTALLATION AND WIRING INSTRUCTIONS
Fig A. Remove ceiling tile and
drill 5/8” (16mm) hole in the
desired location.
Fig D. Install the threaded nut with
shoulder side down and secure.
Fig G. Fasten the lid 3on top of the
junction box. Insert RJ45/Cat cable
into JBM3 receptacle. (See back page
for installing seismic cable)
Fig J. Position the microphone by
turning the cable as necessary
and gently turn the nut clockwise to
secure (1 to 2 turns). Do not
over tighten.
Fig B. Position the JBM3 plenum rated
junction box 2over the drilled hole.
Fig E. Insert the 7 pin mini female XLR
connector into the male receptacle.
Fig H. If using Audix Cat 7 LSOH
interface cable 8 , screw on the
brass bell housing over the RJ45
connection and reset ceiling tile.
Fig K. Microphone elements are
spaced 120 degree apart. Channel 1
is directly below the Audix logo.
Fig C. Remove the nut from the
threaded portion of the M3 cable 1 ,
feed cable through the tile hole and
into the junction box.
Fig F. Set the initial height of the M3
and spool the excess cable inside
the junction box.
Fig I. Adjust the cable to exact
desired length by either feeding
or pulling the cable through the
ceiling mount.
Fig L. Connect RJ45 cables into
the breakout cable and connect
to DSP Controller.

IN THE PACKAGE
The M3 contains three independent microphones and audio channels for interfacing into the mixing
device or audio console. The Audix provided breakout cable 4is designed to interface with a professional
DSP controller using terminal blocks. Audix has an optional breakout cable 7that terminates with three
XLR connectors. The M3 microphone requires phantom power voltage of 18-52 volts.
Microphone Placement: Although the M3 can be hung from a variety of heights, Audix recommends
8’to 8 ½’AFF (above finished floor) placement. When capturing larger zone areas such as open seating or
distance learning, the M3 has a coverage radius up to 10’. Most conference table type coverage, however,
will typically utilize a smaller radius. For example: for a 10’- 12’conference table two M3 microphones are
recommended so that the gain can be lowered and extraneous table and room noise minimized.
Note: The M3 is provided with 4 feet of cable that can be adjusted to the desired height. In cases where
a longer cable is necessary, Audix is able to provide custom lengths. Please call Audix or your local Audix
Sales Representative for more details.
Wiring Tips: Audix CAT 7 cable is recommended to insure high quality, interference free audio over
long distances. For installations where a different brand of CAT 7 cable is being used, please consult
the wiring diagram below. Audix has designed a breakout cable that is available with terminal block
connectors (supplied) or XLR connectors (optional).
BREAKOUT CABLE PIN CONFIGURATION (STANDARD T568B)
SEISMIC / FIRE RESTRAINT INSTRUCTION
Wrap the cable around a beam, eyebolt or hanger.
Then slip the cable through the top of cable stay
barrel pulling excess cable until taut.
To release cable, depress the cable release pin on either
end to release the loop or to extend cable length.
