1 Safety
1.1 Important safety instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Clean only with a dry cloth.
6. Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
1.2 Suspension
Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Electro-Voice strongly recommends that loudspeakers be suspended taking into
account all current national, federal, state, and local laws and regulations. It is the
responsibility of the installer to ensure all loudspeakers are safely installed in accordance
with all such requirements. When loudspeakers are suspended, Electro-Voice strongly
recommends the system be inspected at least once per year or as laws and regulations
require. If any sign of weakness or damage is detected, remedial action should be taken
immediately. The user is responsible for making sure the wall, ceiling, or structure is capable
of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker
not associated with Electro-Voice is the responsibility of others.
Warning!
Do not suspend this product in any other manner than explicitly described in this manual, or
Electro-Voice installation guides. Do NOT use handles to suspend the loudspeaker. Handles
on Electro-Voice loudspeakers are intended to only be used for temporary transport by
people. Items, such as fiber rope, wire rope, cables, or other types of materials cannot be
used to suspend loudspeaker from the handles.
1.3 Precautions
These Electro-Voice loudspeakers were designed for use in an environment with
ambient temperatures between -20°C (-4°F) and +50°C (122°F).
These Electro-Voice loudspeakers are not rated for continuous outdoor
conditions. However, they may be exposed to occasional short-term rain, water,
or high humidity.
Electro-Voice loudspeakers are easily capable of generating sound pressure
levels sufficient to cause permanent hearing damage. Caution should be taken to
avoid prolonged exposure to sound pressure levels exceeding 90 dB.

2 Description
Thank you for choosing an Electro-Voice loudspeaker system. Please take time to consult the
manual to understand all the features built into your EV system and fully utilize its
performance capabilities.
MFX Multi-Function Monitors MFX-12MC and MFX-15MC are passive 12” and 15” coaxial
monitors with a performance level engineered to complement EV’s flagship X-Line Advance
(XLA) line array series.
MFX Multi-Function Monitors utilize high-output coaxially aligned HF and LF transducers and
an innovative, Electro-Voice engineered Constant Directivity waveguide. The dimensions and
location of the waveguide interact with the woofer to effectively create a bipole output,
resulting in precise coverage control through the midrange to the upper frequencies. In
addition to providing a stable sound image as the performer moves off-axis, the compact
coaxial design presents a significantly lower-profile footprint on stage in comparison to
competitive high-end monitors, helping to maintain audience sight lines and reducing stage
clutter. Dual monitor angles allow the enclosure to be precisely directed toward the
performer, while the rugged EVcoat finish and 1.5 mm-thick corrosion-resistant grille combine
professional-grade durability with sleek aesthetics.
These two high-performance stage monitors have a truly multi-functional design. They feature
pole sockets recessed into the side handles for use as short-throw reinforcement in portable
applications. U brackets, yokes, truss clamps, stand-mount adapters, and a rigging bar round
out a full range of mounting accessories for temporary or permanent installation.
In addition to their primary use as stage monitors, these models are also excellent solutions as
side fill, front fill, and delay speakers, as distributed speakers for events, or as the main
speakers for smaller jobs. Target applications include live performance, large corporate
events, worship services and concerts. The multi-functional aspect of the speakers makes
them an attractive investment for production, rental, and live sound companies because the
speakers can be deployed in multiple system roles, keeping more of the rental inventory
working rather than sitting in the warehouse until an appropriate job is booked.
The monitors can be used in passive or biamp configuration. Multiple DSP settings optimize
the speakers for specific uses. The recommended amplifiers for the MFX Multi-Function
Monitors are the TGX and IPX series from EV’s sibling brand, Dynacord.

3 Monitor and pole-mount operation
3.1 Monitor operation
MFX Multi-Functional Monitors provide two monitor angles, depending on the loudspeaker
orientation.
Setting up a loudspeaker as a near field floor monitor
Figure3.1: Monitor angle for close use
To set up a loudspeaker as a near field floor monitor, do the following:
1. Place the loudspeaker on a level stable surface.
2. Position the loudspeaker at an angle of 55° relative to supporting surface so that its main
axis is pointed at the performer.
3. Safely route cables to prevent injury to performers, production crew, and audience
members.
Using the alternate 35° monitor angle
Using the alternate 35° monitor angle, the loudspeaker can be set up as a distant use floor
monitor, a drum monitor, a keyboard monitor, or a side fill.
Figure3.2: Monitor angle for distant use
To set up a loudspeaker as a distant use floor monitor, do the following:
1. Place the loudspeaker on the floor or on a level stable surface at the desired height.
2. Aim the loudspeaker toward the performer at an angle of 35°.
3. Safely route cables to prevent injury to performers, production crew, and audience
members.
Notice!
Secure cables with wire ties or tape whenever possible.

3.2 Tripod or pole-mount operation
MFX Multi-Function Monitors can be mounted on a tripod stand or on a pole above a
subwoofer. Pole cups are located in the recess behind either handle.
Caution!
We recommend that two or more persons lift and place heavier loudspeakers. Single person
lift and placement of heavier loudspeakers could cause injury.
Notice!
The pole cups are only designed to support the weight of a single loudspeaker on a single
pole. Do not attempt to stack these loudspeakers using both pole cups.
Mounting a loudspeaker on a tripod stand
Figure3.3: MFX on a tripod stand (left); Short-medium throw coverage (right)
Caution!
Tripod is not evaluated for safety with this loudspeaker. Check the specifications of the
tripod stand to be certain it is capable of supporting the weight of the loudspeaker.
To mount a loudspeaker on a tripod stand, do the following:
1. Place the tripod stand on a level and stable surface.
– Fully extend the legs on the tripod stand.
– Do not compromise the tripod stand's structural integrity by trying to make the stand
taller.
– Do not attempt to mount more than one loudspeaker on a stand designed for a single
loudspeaker.
2. Lift the loudspeaker using two hands.
3. Align the pole mount socket located inside the handle cavity with the top of the stand and
slide the loudspeaker onto the pole.
Mounting a loudspeaker on a pole
These loudspeakers can also be mounted above a subwoofer, using a standard 35mm (1-3/8")
pole.
