TMK Series
The Electro-Voice® TMK Truss Mount Kits are acces-
sories that are designed to suspend Electro-Voice loud-
speakers to a truss. The bracket allows the speaker to
be rotated in both the horizontal and vertical planes for
maximum versatility (see Figure 1). There are different
suspension kits, depending on the loudspeaker that is
being suspended, as shown in the table below:
WARNING: Suspending any object is potentially danger-
ous and should only be attempted by individuals who
have a thorough knowledge of the techniques and regula-
tions of rigging objects overhead. Electro-Voice® strongly
recommends that all speakers be suspended taking into
account all current national, federal, state and local regu-
lations. It is the responsibility of the installer to ensure that all speak-
ers are safely installed in accordance with all such regulations. When
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.
The user is responsible for making sure that the truss, and any addi-
tional hardware used, is capable of supporting the loudspeaker. Any
hardware used to suspend a loudspeaker that is not associated with
Electro-Voice® is the responsibility of others.

Attaching VSA-1 to Loudspeaker
(all Speakers)
Thread the VSA-1 to the loudspeaker by using the
threaded bracket (PX1122M, PX1152M, Plasma P1) or
HA-3 or HA-5 adaptor (ZX Series) on the right side of
the enclosure. Rotate the loudspeaker to the desired
vertical tilt position, and torque the threaded stud to
the enclosure using the handle (see Figure 5).
Attaching Truss Mount and Speaker Assembly to Truss (all Speakers)
Loosen the clamping fixture on the TCA-1 and open the clamp. Attach the TCA-1 (including the strong arm and
loudspeaker) to the truss by sliding it past the clamping fixture. Adjust the clamp so it is behind the clamping
fixture, and tighten the handle (see Figure 6).

Optional: If local regulations
require an additional safety
point, attach an M10 shoulder
eyebolt (not included) to this
point on the VSA-1.
See Page 4 for required
safety points.
WARNING: The rubber pad acts as a locking mecha-
nism for the threaded shaft. If enough torque is not
applied to the handle, vibrations from the loudspeaker
may loosen the shaft over time. The user should regu-
larly inspect the shaft to ensure that the VSA-1 has not
loosened from the loudspeaker.
