User Instructions

Safety First

The Electro-Voice® PX1122M, PX1152M, PX2122, and PX2152 have threaded points that can be used for suspension.
Please consult the user instructions that are supplied with the suspension kits for proper use prior to installation.

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 rigging objects overhead. Electro-Voice® strongly
recommends that all speakers be suspended taking into account all current national, federal, state and local regulations.
It is the responsibility of the installer to ensure that all speakers are safely installed in accordance with all such
regulations. If Phoenix speakers are suspended, Electro-Voice® strongly recommends that the system be inspected at
least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately. Any
hardware used to suspend a Phoenix speaker that is not associated with Electro-Voice® is the responsibility of others.

Ground Stack:

When using multiple Electro-Voice® Phoenix speakers

in a ground stack configuration, the feet of each
enclosure is designed to fit into grooves of the enclosure
below it. This is both for the safety of the ground stack
and serves as an alignment for properly arraying multiple
loudspeakers. Always check that the feet are resting in
the grooves when using multiple speakers (Figure 1).
Unless you can safely lift the weight of the loudspeaker
on to the ground stack, have another person to help you
place it. The ground stack should be placed on a solid,
level surface. When using subs on a surface that is hard
or slick, use a piece of carpet or other material between
the feet and supporting surface to prevent the subs (and
stacks) from “walking”. When using a ground stack in
windy outdoor conditions, when the surface is slippery , or
when in adverse conditions, Electro-Voice®
recommends using a ratchet strap to secure the
speakers. For a complete list of the configurations

possible with an Electro-Voice® Phoenix system, please

consult the Application Guide at www.electrovoice.com.

Stand Mount:

The Electro-Voice® PX1122M and PX1152M include 1-3/8" stand mounts for use with tripod stands. Check the
specifications of the speaker stand to be certain it is capable of supporting the weight of the speaker. Place the speaker
stand on a flat, stable surface and be sure to fully extend the legs of the stand. Do not try to make the stand “taller” and
compromise its structural integrity. Do not attempt to suspend more than one speaker on a stand designed for a single
speaker. Unless you are confident that you can safely handle lif ting the weight of the speaker onto the stand, ask another
person to help you place it. Route cables and position the stand so that performers, production crew and audience
members will not trip over the stand or cables and pull the speaker system over. Secure the cables with wire ties or tape
whenever possible.

Moisture:

Electro-Voice® does not recommend using Phoenix loudspeakers in the rain or in high moisture environments without
protection.

Hearing Exposure:

Electro-Voice® Phoenix loudspeakers are capable of producing sound pressure levels sufficient to produce permanent
hearing damage. Caution should be taken to avoid prolonged exposure to sound pressure levels exceeding 90 dB.

Processor Settings:

Processor settings for Phoenix loudspeaker configurations are available for Electro-Voice® speaker processors. Please

consult the Application Guide at www.electrovoice.com for more information.

Rotating the Horn:

The PX2122 and PX2152 loudspeakers have horns that can be rotated to change the coverage pattern. The coverage
pattern angles are molded on the horn flange.

1. Remove the (6) screws that attach the grille to the enclosure (Figure 2).

2. Remove the (12) screws that attach the horn to the enclosure, and disconnect the wires that attach the ND2 to the input
panel (Figure 3). The jumper that is between both ND2’s can remain connected.

3. Remove the (4) nuts and bolts that connect the manifold to the horn. Rotate the horn 90° so the desired vertical
coverage pattern is parallel to the ND2’s and manifold, then reattach the manifold using the (4) nuts and bolts (Figure 4).

4. Reconnect the wires that attach the ND2 to the input panel (reverse of Figure 3). The yellow wire corresponds to the
positive terminal, and the yellow and black wire corresponds to the negative terminal. Reattach the horn to the enclosure
using the (12) screws.

5. Reattach the grille using the (6) screws (reverse of Figure 2).
