IN THE PACKAGE
OPTIONALACCESSORIES
M3 Tri-element Hanging Ceiling Microphone
JBM3 - Plenum rated junction box circuitry
Junction box lid
Breakout cable consisting of RJ45 female to three terminal block connectors
Seismic / Fire restraint cable
PLENHSEM3 Brass plenum bell housing (patent pending). This brass
housing is specically 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.
CAT7 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 individu-
ally 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).
Note: The Audix M3 also works with CAT 5 and CAT 6 cable, however, Audix recommends
using shielded cable.
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')
CBLM330 - Interface Cable 30 meters (98')
CBLM350 - Bulk cable. 50 meters (162’). Use with brass plenum bell housing #6 for best results.

desired length by either feeding
or pulling the cable through the
ceiling mount.

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.

M3 TRI-ELEMENT OPERATING PROCEDURE
The M3 contains three independent microphones and audio channels for interfacing into the mixing
device or audio console. The Audix provided breakout cable is designed to interface with a profes-
sional DSP controller using terminal blocks.
Audix has an optional breakout cable that terminates with three XLR connectors.
The M3 microphone requires phantom power voltage of 18-52 volts.
BREAKOUT CABLE PIN CONFIGURATION (STANDARD T568B)
Microphone Placement
Although the M3 can be hung from a variety of heights, Audix recommends 8’ to 8 ½’ AFF (above
nished oor) 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 dis-
tances. 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).
